California Bus. & Prof. Code § 6731 California Licensed Geotechnical Engineer (GE) attorney fee petition mechanics: BPELSG License Verification at check.bpelsg.ca.gov GE specialty license as primary Welch anchor — ASTM D1586-18 SPT N₀ Correction Advisory and ASCE/SEI 7-22 Site Class F Advisory — TWO PRIVATE STANDARDS — PURE KETCHUM

Billing gap 1 — BPELSG GE license verification, ASTM D1586-18 N₆₀ correction advisory, and ASCE/SEI 7-22 Site Class F advisory hours (5.25 hrs)

Every California professional licensing board fee petition under Code of Civil Procedure § 1021.5 begins with the institutional threshold verification that grounds the entire fee petition chronology. For a California Licensed Geotechnical Engineer matter under Bus. & Prof. Code § 6731, the attorney begins with the BPELSG License Verification system at check.bpelsg.ca.gov — the primary Welch anchor. The Board for Professional Engineers, Land Surveyors, and Geologists (BPELSG) administers the California professional engineering licensing framework and maintains a searchable online database of all active, inactive, suspended, revoked, and expired California professional engineering licenses, including the GE specialty licenses issued under Bus. & Prof. Code § 6731 as a license category entirely separate from the Civil Engineer PE licenses issued under Bus. & Prof. Code § 6730. An attorney investigating a § 6731 unlicensed geotechnical engineering matter accesses check.bpelsg.ca.gov, enters the respondent's full name or license number, and receives a license status record showing the respondent's license type (PE, GE, CEG, or PG), license number, current status, expiration date, and the specialty designation — or, in the case that the respondent holds no GE specialty license, a result confirming only a PE designation with no GE specialty. This record is the primary Welch anchor under Welch v. Metropolitan Life Ins. Co. 480 F.3d 942 (9th Cir. 2007): a timestamped government record generated by the BPELSG, entirely outside the attorney's control, confirming whether the respondent held a valid GE specialty license on the dates the geotechnical investigation report at issue was prepared, signed, and submitted to obtain the California building permit. In many § 6731 matters, the respondent holds an active Civil PE license — making the § 6731 unlicensed practice claim turn on the distinction between the broad civil engineering scope of the PE license and the geotechnical engineering specialty practice authorized only by the GE license, a distinction that is captured precisely in the BPELSG check.bpelsg.ca.gov GE specialty registry that confirms no GE designation even when a PE designation is present. Conducting the BPELSG license verification search, reviewing the license status across PE, GE, CEG, and PG categories, drafting the license verification memo documenting the GE specialty absence, and preparing the scope-of-practice analysis distinguishing the § 6731 GE authorization from the Civil PE (§ 6730), CEG (§ 7832), and PG (§ 7828) practice scopes requires 0.75 hours.

The BPELSG license verification is supplemented by secondary institutional confirmation from city and county building department records — the engineer-of-record records from the building permit file for the project at which the unlicensed geotechnical engineering occurred. California building departments maintain permit files that include the geotechnical investigation report submitted with the building permit application, identify the engineer who signed and stamped the geotechnical report with their license number, and typically include the plan check record documenting any review of whether the submitting engineer's license authorized geotechnical engineering practice. Requesting the permit file for the project at issue — through a California Public Records Act (Gov. Code § 7920.000 et seq.) request to the issuing city or county building department — returns a government record from a California governmental entity separate from BPELSG confirming the identity of the engineer whose signature appears on the geotechnical investigation report and, in many jurisdictions, whether the building department plan checker raised any concern about the engineer's licensing status. In cases where the building permit was issued without a plan checker verification of GE specialty licensure — which was typically the case in the Riverside County grading harm track, where the city issued a grading permit without verifying that the soils report signatory held a GE specialty license rather than only a Civil PE license — the permit file constitutes secondary institutional evidence from a separate governmental entity that the unlicensed geotechnical work proceeded through the building permit process without the mandatory GE specialty license review that § 6731 requires. Requesting, reviewing, and documenting the building department engineer-of-record secondary record requires 0.50 hours.

After the institutional anchors are established, Billing Gap 1 continues with the ASTM D1586-18 advisory — the first of the two private standards in the § 6731 GE fee petition pattern. ASTM International — the American Society for Testing and Materials — is a private voluntary standards development organization founded in 1898, headquartered in West Conshohocken, Pennsylvania, and is one of the world's largest voluntary standards development organizations, producing over 12,500 standards governing materials, products, systems, and services across a wide range of industries including construction materials, geotechnical testing, and soil mechanics. ASTM D1586-18 Standard Test Method for Standard Penetration Test (SPT) and Split-Barrel Sampling of Soils is the governing standard for the SPT — the most widely used in-situ soil testing method in California geotechnical practice, used on virtually every geotechnical investigation involving building foundations, retaining wall design, or seismic site classification. The SPT involves driving a standard split-barrel sampler with an outside diameter of 2 inches and an inside diameter of 1 3/8 inches into the undisturbed soil at the bottom of a borehole using a 140-pound hammer dropped 30 inches, recording the number of blows (N-value or blow count) required to advance the sampler through three successive 6-inch increments after an initial seating drive — the sum of the blow counts for the second and third 6-inch increments constitutes the reported SPT N-value. Three ASTM D1586-18 provisions are directly applicable to the San Jose mixed-use building harm track. First, ASTM D1586-18 Section 5.3 energy ratio requirement — Section 5.3 establishes that automatic trip hammers must deliver an energy ratio (ER) of at least 60% to the drill rod system to produce consistent, reproducible N-values that can be used reliably in bearing capacity and liquefaction triggering calculations; the energy ratio is the ratio of the actual energy delivered to the drill rod to the theoretical free-fall energy of the hammer, measured using a calibrated energy measurement system attached to the drill rod directly above the sampler, and the 60% minimum reflects the standardization that underlies all published SPT-based bearing capacity correlation charts used in California practice. Second, ASTM D1586-18 Section 7.2 mandatory N₆₀ correction procedure — Section 7.2 establishes the mandatory corrected SPT blow count calculation: the corrected N-value (N₆₀) equals the measured raw N-value multiplied by the ratio (ER_actual/60), where ER_actual is the measured energy ratio of the specific hammer system used on the specific borehole; this correction must be applied before N-values are used in bearing capacity formulas, liquefaction triggering calculations, or any other geotechnical design analysis that relies on published SPT correlation charts calibrated to the 60% energy ratio standard. In the San Jose mixed-use building harm track, the automatic trip hammer delivered ER_actual = 78%, meaning that every raw N-value recorded in the boring logs was 30% below the N₆₀ value that should have been used in design — raw N = 12 blows should have been entered into the bearing capacity calculation as N₆₀ = 12 × (78/60) = 15.6, producing an allowable bearing pressure of approximately 4,800 psf using Terzaghi's general bearing capacity equation; instead, the unlicensed engineer used the raw N = 12 value directly, producing an allowable bearing pressure of 2,800 psf — only 58% of the correct value, meaning the allowable bearing pressure was overstated by a factor of 1.8 and the spread footings were sized for a load they could not actually support. Third, ASTM D1586-18 Section 10.1 boring log documentation requirements — Section 10.1 requires the boring log to document the SPT N-values at each 2.5-foot test interval, the soil description in accordance with ASTM D2488 Unified Soil Classification System, the groundwater depth encountered during drilling and its stabilized level upon completion, the sample recovery percentage for each split-barrel sample, and critically — the hammer type and the measured energy ratio for the specific rig and hammer combination used on the boring. Failure to document the hammer energy ratio in the boring log makes post-hoc N₆₀ correction impossible and constitutes a Section 10.1 violation that undermines all bearing capacity and liquefaction triggering analyses derived from the boring program; in the San Jose building harm track, the boring logs documented N-values without any energy ratio information, precluding the city's plan checking engineers from independently verifying the N₆₀ correction that should have been applied. ASTM International is a private voluntary standards development organization — ASTM D1586-18 creates no private civil right of action and no mandatory attorney fee-shifting mechanism for property owners, building occupants, or workers harmed by unlicensed geotechnical engineering practice. PURE KETCHUM: the attorney fee entitlement flows from CCP § 1021.5. Drafting the ASTM D1586-18 advisory memo — including the Section 5.3 energy ratio requirement and the 60% standardization basis, the Section 7.2 N₆₀ correction calculation for the San Jose building ER = 78% hammer (N_raw = 12 → N₆₀ = 15.6 → bearing capacity overstatement analysis), the Section 10.1 boring log documentation audit confirming energy ratio was not recorded, the ASTM International organizational background, and the PURE KETCHUM distinction — requires 1.50 hours.

The ASTM D1586-18 advisory is immediately followed by the ASCE/SEI 7-22 advisory — the second private standard that makes this § 6731 Billing Gap 1 the only billing gap in the California professional licensing board fee-petition-mechanics series with BOTH an ASTM D1586-18 STANDARD PENETRATION TEST SPT N₆₀ CORRECTION ADVISORY AND an ASCE/SEI 7-22 MINIMUM DESIGN LOADS SITE CLASSIFICATION ADVISORY — TWO PRIVATE STANDARDS ON ONE PAGE. The American Society of Civil Engineers (ASCE) is a private nonprofit professional engineering organization founded in 1852, headquartered in Reston, Virginia, and is the oldest national engineering society in the United States, representing over 150,000 civil engineers worldwide. ASCE publishes ASCE/SEI 7 — Minimum Design Loads and Associated Criteria for Buildings and Other Structures — through its Structural Engineering Institute (SEI), drawing on the expertise of structural engineers, geotechnical engineers, wind engineers, and seismic hazard specialists across industry, academia, and government, to establish the minimum structural design load and performance criteria that are adopted by reference into the California Building Code and used on every California structural engineering project. The 2022 edition, ASCE/SEI 7-22, is the current adopted edition in California and governs the seismic site classification procedure and associated ground motion parameters for every California building permit application. Three ASCE/SEI 7-22 provisions are directly applicable to the Santa Barbara County hillside retaining wall harm track. First, ASCE/SEI 7-22 Section 20.3 Site Classification procedure — Section 20.3 assigns sites to one of six Site Classes (A through F) based on three possible measurement approaches: measured average shear wave velocity Vs,30 (average shear wave velocity of the top 30 meters), average corrected SPT blow count N₆₀ across the top 30 meters, or average undrained shear strength Su in the top 30 meters. Site Class F — the most hazardous classification requiring site-specific ground motion analysis — applies whenever the site profile contains any of the following: soft clay more than 10 feet thick where soft clay is defined as soil with undrained shear strength Su less than 500 psf, water content at least 40%, and plasticity index greater than 20; or liquefiable soils, quick and highly sensitive clays, collapsible weakly cemented soils. The 16-foot thick soft alluvial clay layer underlying the Santa Barbara County hillside retaining wall site — with SPT N₆₀ values of 3–6 blows per foot, water content of 42–48%, and plasticity indices of 28–34 — satisfied all three of the Section 20.3 Site Class F soft-clay criteria simultaneously, making the Site Class F classification mandatory rather than discretionary. Second, ASCE/SEI 7-22 Section 11.4.3 site-specific ground motion requirement — Section 11.4.3 states that when Site Class F conditions are determined to be present, the design ground motion parameters Ss (short-period spectral acceleration) and S1 (1-second period spectral acceleration) must be determined using a site-specific ground motion analysis procedure conforming to Section 21.1 rather than reading from the standard USGS National Seismic Hazard Maps; the standard mapped values at the Santa Barbara County site location assume a Site Class D baseline condition — using the standard Site Class D mapped values for a Site Class F site can underestimate the spectral acceleration at the fundamental period of the retaining wall-soil system by a factor of 1.3 to 1.6, producing a proportional understatement of the seismic lateral earth pressure acting on the retaining wall during an M 4.8 earthquake with a Site Class F site amplification response. Third, ASCE/SEI 7-22 Section 11.8 geotechnical investigation report content requirements — Section 11.8 establishes that for projects requiring seismic design, the geotechnical investigation report must describe subsurface conditions including boring locations and depths, SPT N₆₀ values and recovery percentages, groundwater elevation, liquefaction potential with triggering analysis using the Robertson and Wride (1998) or Youd et al. (2001) methodology, post-liquefaction settlement estimates, and the basis for the Seismic Design Category determination; a geotechnical report that fails to identify a Site Class F condition in the presence of a 16-foot soft clay layer with N₆₀ = 3–6, water content = 42–48%, and PI = 28–34 is a report that fails the Section 11.8 content standards because it does not document the investigation that would have identified the Site Class F condition — specifically, the undrained shear strength testing (lab UU triaxial or field vane shear) required by Section 20.3 to confirm or refute the apparent Site Class F indicators from the SPT N₆₀ data alone. The American Society of Civil Engineers is a private nonprofit organization — ASCE/SEI 7-22 creates no private civil right of action and no mandatory attorney fee-shifting mechanism. PURE KETCHUM: the attorney fee entitlement flows from CCP § 1021.5. Drafting the ASCE/SEI 7-22 advisory memo — including the Section 20.3 Site Class F identification analysis for the Santa Barbara County hillside retaining wall site (N₆₀ = 3–6, water content = 42–48%, PI = 28–34 satisfying all three soft-clay criteria), the Section 11.4.3 mandatory site-specific ground motion analysis requirement and the spectral acceleration underestimation that resulted from using Site Class D mapped values for a Site Class F site, the Section 11.8 geotechnical report content audit confirming absence of undrained shear strength testing documentation, the ASCE organizational background, and the PURE KETCHUM distinction — and preparing the CCP § 1021.5 pre-suit demand letter documenting the § 6731 certification violation, the ASTM D1586-18 Section 7.2 N₆₀ correction omission and bearing capacity overstatement, the ASCE/SEI 7-22 Section 20.3 Site Class F identification failure, and the public interest basis requires 1.00 hour for the ASCE advisory and 1.50 hours for the demand and intake, bringing the total Billing Gap 1 time — BPELSG license verification (0.75 hrs), building department secondary record (0.50 hrs), ASTM D1586-18 advisory (1.50 hrs), ASCE/SEI 7-22 advisory (1.00 hr), and client intake and CCP § 1021.5 pre-suit correspondence (1.50 hrs) — to 5.25 hours, recoverable at $300–$500/hr under the Ketchum lodestar.

Billing gap 2 — Tyler Odyssey complaint filing and three-track harm documentation (4.00 hrs)

Billing Gap 2 begins when the attorney files the civil complaint through Tyler Technologies Odyssey File & Serve — California's electronic court filing platform used by the superior courts in Los Angeles, San Francisco, Alameda, Contra Costa, San Diego, Orange, Riverside, San Bernardino, Sacramento, Santa Clara, Ventura, and the majority of California's 58 counties, covering the geographic markets where § 6731 unlicensed geotechnical engineering harm most frequently arises because California's seismically active built environment — spanning the San Francisco Bay Area's infilled Bay Mud soils and liquefaction-susceptible alluvial deposits, the Los Angeles Basin and Inland Empire's expansive clay and alluvial fan soils, Orange County and San Diego's coastal hillside and canyon sites with soft clay and landslide susceptibility, and the Central Valley's compressible alluvial and agricultural soils — creates extensive demand for geotechnical investigation services where foundation, slope stability, and seismic site classification errors have disproportionately large consequences, and creates corresponding risk when geotechnical services are performed by Civil PE engineers operating outside their license scope or by individuals with no current California professional engineering license at all. The Tyler Odyssey filing timestamp constitutes the primary contemporaneous record under Welch v. Metropolitan Life Ins. Co. 480 F.3d 942 (9th Cir. 2007): it is a government-generated, immutable record establishing the date, the case number, the parties, and the relief sought, created by a system entirely outside the attorney's control at the exact moment of filing. In a California GE matter under Bus. & Prof. Code § 6731, the complaint alleges violation of § 6731 and the unlicensed practice prohibition (performing geotechnical engineering services including preparation of geotechnical investigation reports with foundation recommendations, bearing capacity determinations, and seismic site classifications without holding a valid GE specialty license — signing a geotechnical investigation report for a six-story mixed-use building on Bay Mud-influenced soils without the GE specialty license that authorizes SPT-based bearing capacity analysis, or designing the seismic earth pressure loading on a hillside retaining wall without the GE specialty license that authorizes seismic site classification and liquefaction triggering analysis, or submitting a grading soils report for a 4.2-acre commercial grading project without the GE specialty license that authorizes geotechnical engineering-of-record services for graded fill pads), violation of CCP § 1021.5 (by seeking enforcement of an important right affecting the public interest — the requirement that all California geotechnical investigation reports containing foundation recommendations, bearing capacity determinations, slope stability analyses, and seismic site classifications be prepared and signed only by licensed GEs who have demonstrated the examination competency and experience under responsible charge that underpin the GE specialty license — that protects thousands of California building occupants, property owners, and workers from foundation failures, differential settlement, seismic collapses, and grading catastrophes caused by deficient geotechnical engineering practice), and seeks injunctive relief, civil penalties, and mandatory attorney fees under CCP § 1021.5. Drafting, reviewing, and filing the complaint through Tyler Odyssey requires 1.25 hours of Billing Gap 2 time.

The three-track harm documentation phase of Billing Gap 2 begins with the retention and briefing of qualified geotechnical and structural engineering expert witnesses under Sargon Enterprises, Inc. v. University of Southern California (2012) 55 Cal.4th 747. In a § 6731 California GE matter with the three identified harm tracks, the appropriate expert witnesses are: (1) a California Licensed Geotechnical Engineer (GE) with SPT-based bearing capacity analysis and Bay Mud soil mechanics experience to address the San Jose mixed-use building harm track — specifically, the ASTM D1586-18 Section 7.2 N₆₀ correction calculation demonstrating that N_raw = 12 at ER_actual = 78% produces N₆₀ = 15.6 and an allowable bearing pressure of approximately 4,800 psf rather than the 2,800 psf calculated from the uncorrected N-value, the 1.8× overstatement factor that caused the spread footings to be undersized, and the causal relationship between the undersized footings and the 3.2-inch differential settlement and structural frame cracking in the 6-story building; (2) a California Licensed Geotechnical Engineer (GE) with soft clay seismic site classification and liquefaction triggering analysis experience to address the Santa Barbara County hillside retaining wall harm track — specifically, the ASCE/SEI 7-22 Section 20.3 Site Class F identification methodology for the 16-foot soft clay layer with N₆₀ = 3–6, water content = 42–48%, PI = 28–34 satisfying all three soft-clay criteria, the Section 11.4.3 site-specific ground motion analysis that would have produced spectral accelerations approximately 1.3–1.6 times the Site Class D values used in the retaining wall seismic design, and the causal relationship between the Site Class F misidentification and the seismic lateral earth pressure deficit that caused the retaining wall to fail during the M 4.8 earthquake; and (3) a California Licensed Geotechnical Engineer (GE) with grading compliance and compaction monitoring experience to address the Riverside County commercial grading harm track — specifically, the BPELSG GE specialty license requirement for geotechnical engineering-of-record services on commercial graded fill pads under the Riverside County Grading Ordinance, the absence of a GE-stamped compaction specification, and the city's grading permit revocation and stop work order. Briefing all three experts, providing the BPELSG license verification records, ASTM D1586-18 advisory, and ASCE/SEI 7-22 advisory materials requires 1.00 hour of Billing Gap 2 attorney time.

Track 1 harm documentation — SAN JOSE — 6-STORY MIXED-USE BUILDING — GROUND-FLOOR RETAIL AND FIVE FLOORS RESIDENTIAL — GE LICENSE EXPIRED 22 MONTHS BEFORE GEOTECHNICAL REPORT DATE — ASTM D1586-18 SECTION 7.2 N₆₀ CORRECTION OMITTED — RAW N-VALUES USED DIRECTLY IN TERZAGHI BEARING CAPACITY EQUATION — ALLOWABLE BEARING PRESSURE OVERSTATED BY FACTOR OF 1.8 — SPREAD FOOTINGS UNDERSIZED — POST-CONSTRUCTION DIFFERENTIAL SETTLEMENT 3.2 INCHES — STRUCTURAL FRAME CRACKING AT SECOND AND THIRD FLOOR BEAM-COLUMN CONNECTIONS — BUILDING RED-TAGGED AND EVACUATED — BPELSG COMPLAINT FILED — $285,000. The engineer — a civil engineer who had previously held a GE specialty license but whose license had expired 22 months before the geotechnical report date, who retained only an active Civil PE (§ 6730) license with no current GE specialty, and who continued to offer and perform geotechnical investigation services in the San Jose Bay Area market — was retained to prepare the geotechnical investigation report for a six-story mixed-use building on infilled downtown soils. The boring program used an automatic trip hammer with a measured energy ratio of ER_actual = 78%, but the boring logs recorded only raw N-values without documenting the measured energy ratio as required by ASTM D1586-18 Section 10.1, and the bearing capacity analysis used the raw N-values directly in Terzaghi's general bearing capacity equation without applying the Section 7.2 N₆₀ correction. At the critical stratum depth for footing design, raw N = 12 blows was used directly, yielding an allowable bearing pressure of q_a = 2,800 psf; the N₆₀-corrected value would have been N₆₀ = 12 × (78/60) = 15.6, yielding q_a = 4,800 psf — a factor of 1.8 higher than the calculated value used for design. The spread footings for the six-story building were sized based on the overstated 2,800 psf allowable bearing pressure, resulting in spread footing areas approximately 42% smaller than required for the actual N₆₀-corrected bearing capacity of the bearing stratum. Post-construction monitoring installed by the structural engineer of record revealed differential settlement exceeding 3.2 inches between the northwest corner footings on the softer compressible fill stratum and the central core footings on the firmer native alluvium within 18 months of occupancy — a settlement pattern inconsistent with the uniform settlement predicted by the geotechnical report's overstated bearing capacity and consistent with the N₆₀-corrected analysis showing significantly lower bearing capacity in the fill-influenced soils. Structural frame cracking developed at the second and third floor beam-column moment connections as the differential settlement imposed unintended lateral loads on the moment frame; the city building official, upon a complaint from a structural engineer retained by the residential unit owners, issued a red-tag requiring vacation of all five floors of residential units. A BPELSG complaint was filed documenting the expired GE specialty license; BPELSG opened a formal investigation confirming the license had been expired 22 months before the geotechnical report was signed. Total Track 1 harm: $285,000 (emergency structural assessment and evacuation costs, temporary relocation of residential tenants, underpinning and foundation remediation costs, BPELSG civil penalty assessment, structural repairs to moment connections at beam-column joints). Documenting Track 1 — the BPELSG records confirming the GE license expired 22 months before the report date, the ASTM D1586-18 Section 7.2 N₆₀ correction analysis and bearing capacity overstatement, the boring log Section 10.1 documentation audit, the post-construction settlement records and structural damage documentation, and the BPELSG complaint and investigation records — requires 0.50 hours of Billing Gap 2 time.

Track 2 and Track 3 harm documentation encompasses the Santa Barbara County hillside retaining wall liquefaction collapse and the Riverside County commercial grading permit revocation — SANTA BARBARA COUNTY — HILLSIDE RESIDENTIAL RETAINING WALL — 14-FOOT REINFORCED CONCRETE RETAINING WALL — UNLICENSED CIVIL PE WITHOUT GE LICENSE — ASCE/SEI 7-22 SECTION 20.3 SITE CLASS F SOFT-CLAY DEPOSIT NOT IDENTIFIED — SEISMIC DESIGN USED SITE CLASS D — WALL FOOTING UNDERSIZED FOR SITE CLASS F SPECTRAL ACCELERATIONS — M 4.8 EARTHQUAKE — LIQUEFACTION TRIGGERED — WALL COLLAPSED — $195,000; and RIVERSIDE COUNTY — COMMERCIAL GRADING PROJECT — 4.2-ACRE RETAIL PAD SITE — NO GE REVIEW — GE LICENSE NEVER OBTAINED — COMPACTION SPECIFICATION ABSENT — GRADING PERMIT REVOKED — STOP WORK ORDER — $95,000. For Track 2, a residential property owner retained a Civil PE — who held an active § 6730 PE license but had never held a § 6731 GE specialty license — to prepare a geotechnical investigation and structural design for a 14-foot reinforced concrete retaining wall on a hillside residential lot in the Santa Barbara County hills. The geotechnical investigation identified a 16-foot thick layer of soft alluvial clay beginning at 4 feet below grade; SPT N₆₀ values in the clay layer (using N₆₀-corrected values where energy ratio data was available, or directly from low raw N-values where not) ranged from 3 to 6 blows per foot — consistent with soft to very soft clay. Moisture content testing on samples from the clay layer returned values of 42–48%, and Atterberg limits testing yielded plasticity indices of 28–34. These measurements satisfied all three of the ASCE/SEI 7-22 Section 20.3 Site Class F soft-clay criteria — undrained shear strength Su less than 500 psf (confirmed by unconfined compression tests at Su = 280–340 psf), water content at least 40% (confirmed 42–48%), and plasticity index greater than 20 (confirmed 28–34) — making Site Class F classification unambiguous. The Civil PE classified the site as Site Class D — the default classification used in practice when no Vs,30 measurement has been performed and N₆₀ values exceed the soft soil threshold — without conducting the undrained shear strength testing or water content measurements required by Section 20.3 to confirm or refute the apparent Site Class F indicators from the SPT data alone, and without performing the site-specific ground motion analysis under Section 11.4.3 that Site Class F mandated. The retaining wall footing was designed using the standard USGS Site Class D mapped spectral accelerations for the Santa Barbara County hillside location, which at the site's Ss and S1 map coordinates produced a seismic coefficient for the retaining wall design that was approximately 40% below what a site-specific analysis for Site Class F would have required — directly causing the wall footing to be undersized for the lateral earth pressures that a Site Class F M 4.8 earthquake would generate. During a M 4.8 earthquake centered near the Santa Barbara area, ground shaking triggered liquefaction in the soft clay layer; the seismic lateral earth pressure acting on the retaining wall exceeded the passive resistance capacity of the undersized footing by a significant margin, and the wall rotated and collapsed outward, depositing approximately 200 cubic yards of liquefied saturated soil and wall debris onto the adjacent lower terrace and into the neighboring yard. The homeowner sustained $195,000 in property damage, retaining wall replacement costs, neighbor damage remediation costs, and geotechnical investigation and design fees for the replacement wall — with the Civil PE unable to provide professional liability coverage for the unlicensed geotechnical practice because his errors and omissions insurer denied coverage for geotechnical engineering services conducted outside the scope of a PE license. Documenting Track 2 — the BPELSG records confirming no GE specialty license, the ASCE/SEI 7-22 Section 20.3 Site Class F analysis showing the three criteria simultaneously satisfied, the Section 11.4.3 site-specific ground motion analysis omission, the M 4.8 earthquake records from USGS and SCEC confirming the seismic event date and Richter magnitude, and the property damage and insurance declination documentation — requires 0.75 hours of Billing Gap 2 time. For Track 3, a commercial developer retained a Civil Engineering firm whose principal held only a Civil PE (§ 6730) license to submit a grading plan and soils report for a 4.2-acre commercial pad site in Riverside County. The soils report bore the Civil PE's stamp and stated that no geotechnical investigation was required because the site was underlain by competent native alluvium; no GE was involved in preparing or reviewing the report. The City of Riverside Grading Inspector noted during field inspection of grading operations that imported fill was being compacted without a geotechnical engineer-of-record monitoring compaction in real time, that no field density testing program had been established, and that no compaction specification existed in the permit file. The City Building Official reviewed the permit file, confirmed that the soils report had been signed by a Civil PE rather than a licensed GE as required by the Riverside County Grading Ordinance for commercial graded pads intended to support structures, and issued a stop work order and permit revocation notice. The developer was required to obtain a BPELSG-licensed GE, prepare a complete geotechnical investigation from scratch including SPT borings to establish N₆₀-based bearing capacity for the fill pads, prepare a GE-stamped compaction specification and earthwork inspection protocol, resubmit grading plans under BPELSG GE-of-record certification, and pay $95,000 in City of Riverside civil fines for grading without a valid permit and for altering natural drainage patterns without proper authorization — in addition to the cost of demolishing and recompacting previously placed fill that lacked GE-certified compaction documentation. Documenting Track 3 — the BPELSG records confirming no GE specialty license, the Riverside City permit records showing the Civil PE signature without GE designation on the soils report, the stop work order and permit revocation records, and the civil fine assessment — requires 0.50 hours of Billing Gap 2 time. The total Billing Gap 2 time — complaint filing (1.25 hrs), expert retention and briefing (1.00 hr), Track 1 documentation (0.50 hrs), Track 2 documentation (0.75 hrs), and Track 3 documentation (0.50 hrs) — sums to 4.00 hours.

Billing gap 3 — fee petition, lodestar, Ketchum multiplier, and fees-on-fees (4.00 hrs)

Billing Gap 3 in the California Licensed Geotechnical Engineer GE fee-petition-mechanics pattern is the fee petition itself — the formal court filing presenting the attorney's lodestar calculation, requesting a Ketchum enhancement, and seeking fees-on-fees for the time spent preparing the petition. California's mandatory attorney fee petition practice in professional certification matters is governed by the lodestar methodology established by the United States Supreme Court in Hensley v. Eckerhart 461 U.S. 424 (1983) and adopted by the California Supreme Court as the standard for calculating reasonable attorney fees under California fee-shifting statutes including CCP § 1021.5. Under the lodestar methodology, the reasonable fee is the product of the reasonable number of hours expended on the litigation multiplied by the reasonable hourly rate — the lodestar figure — which may then be adjusted upward based on the factors identified in Ketchum v. Moses 24 Cal.4th 1122 (2001) and PLCM Group Inc. v. Drexler 22 Cal.4th 1084 (2000). Drafting the fee petition for a § 6731 California Licensed GE matter requires the attorney to assemble the complete billing record — all ClaimHour-generated contemporaneous time entries for Billing Gaps 1, 2, and 3 — and present them in a format satisfying Welch v. Metropolitan Life Ins. Co. 480 F.3d 942 (9th Cir. 2007): each entry must show the date, the timekeeper, the hours spent, and a description of the task sufficiently specific to allow the opposing party and the court to evaluate the reasonableness of the time claimed without requiring reconstruction from memory. In a § 6731 matter, the fee petition declaration must address the technical content of the ASTM D1586-18 advisory and the ASCE/SEI 7-22 advisory — explaining why reviewing the Section 7.2 N₆₀ correction calculation and bearing capacity overstatement analysis for the San Jose building required the specific time claimed for the ASTM advisory memo; and why reviewing ASCE/SEI 7-22 Section 20.3 Site Class F identification methodology, Section 11.4.3 site-specific ground motion analysis requirements, and Section 11.8 geotechnical report content standards for the Santa Barbara retaining wall required the specific time claimed for the ASCE advisory memo — and identifying the GE bearing capacity analysis, seismic site classification, and grading compliance experts whose involvement the attorney coordinated under Sargon Enterprises v. USC (2012) 55 Cal.4th 747. Drafting the fee petition and supporting declaration requires 1.50 hours of Billing Gap 3 time.

The lodestar calculation in a § 6731 California Licensed GE matter proceeds from the community standard hourly rate for the work performed. Under PLCM Group Inc. v. Drexler 22 Cal.4th 1084 (2000), the reasonable hourly rate is the prevailing market rate in the relevant community for attorneys of comparable skill, experience, and reputation performing the same type of work. For professional certification fee petition work involving unlicensed geotechnical engineering claims in the San Francisco Bay Area, Los Angeles Basin, Orange County, Santa Barbara County, and Riverside-San Bernardino Inland Empire markets — the geographic markets where § 6731 unlicensed GE disputes most frequently arise because California's seismically active geology, its extensive hillside residential and commercial development, its extensive use of SPT-based geotechnical investigations for building permit applications, and its large population of Civil PE engineers who may be tempted to extend their practice into geotechnical engineering without obtaining the separate GE specialty license create substantial conditions for unlicensed geotechnical practice — the prevailing market rate for experienced consumer protection and professional licensing board attorneys ranges from $300 per hour at the lower end to $500 per hour at the higher end. At $300/hr, the 13.25 annual hours across the three billing gaps produce a lodestar of $3,975. At $500/hr, the same 13.25 hours produce a lodestar of $6,625. The PLCM rate declaration must support the claimed hourly rate with declarations from attorneys of similar experience in the same geographic market and evidence from published hourly rate surveys for public safety enforcement, geotechnical engineering malpractice, and professional licensing board practice in California. Calculating the lodestar, applying the PLCM community-rate analysis, and preparing the rate declaration requires 0.75 hours of Billing Gap 3 time.

The Ketchum multiplier analysis is the component of Billing Gap 3 that most distinguishes California professional licensing certification fee petition practice from federal fee-shifting practice. In Ketchum v. Moses 24 Cal.4th 1122 (2001), the California Supreme Court held that the lodestar figure may be adjusted to account for factors including the contingent risk borne by the attorney, the novelty and complexity of the issues, the skill displayed in presenting them, the results achieved, and the extent to which the case precluded other employment. In a § 6731 California Licensed GE matter, the Ketchum multiplier analysis focuses on three distinct enhancement arguments: (1) the contingent risk — unlicensed geotechnical engineering typically presents collection uncertainty because the respondent may be a sole-proprietor civil engineering consultant or small PE firm who operated without professional liability coverage for geotechnical engineering services (professional liability insurers routinely exclude from PE policies any geotechnical engineering claims if the insured does not hold a GE specialty license, because geotechnical engineering presents a distinct risk profile from general civil engineering practice), whose net assets as a small engineering firm may be insufficient to satisfy a judgment without insurance proceeds, and whose insurance coverage may have lapsed before the harm was discovered given the typically long development time between geotechnical report preparation and the manifestation of foundation failure or differential settlement; (2) the technical complexity — reviewing ASTM D1586-18 Section 7.2 N₆₀ correction calculations for a specific automatic trip hammer energy ratio, reconstructing the bearing capacity analysis from raw N-values and demonstrating the quantified overstatement factor of 1.8× using Terzaghi's general bearing capacity equation and the applicable California geotechnical practice parameters, establishing the causal relationship between the overstatement factor and the observed 3.2-inch differential settlement in the six-story mixed-use building through geotechnical settlement analysis; reviewing ASCE/SEI 7-22 Section 20.3 soft-clay Site Class F criteria against three independent measured soil parameters (undrained shear strength, water content, and plasticity index), analyzing the site-specific spectral acceleration differences between Site Class D and Site Class F at the Santa Barbara County site's Ss and S1 mapped values, calculating the seismic lateral earth pressure deficit for the retaining wall footing design using Mononobe-Okabe seismic earth pressure theory with the Site Class F versus Site Class D spectral coefficients, and establishing the causal pathway from the Site Class F misidentification through the wall footing size to the wall collapse during the M 4.8 earthquake; coordinating bearing capacity analysis, seismic site classification, and grading compliance GE experts across three technically distinct geotechnical harm scenarios — each involving different soil conditions, different ASTM and ASCE standard provisions, and different BPELSG licensing scope issues; and translating Terzaghi bearing capacity equations, ASTM D1586-18 N₆₀ energy correction procedures, ASCE/SEI 7-22 Site Class F classification criteria, and seismic lateral earth pressure calculations for a lay jury across multiple geotechnical subdisciplines within a single GE licensing enforcement action; and (3) the public benefit — Bus. & Prof. Code § 6731 protects California property owners, building occupants, and the public from geotechnical investigation reports prepared and signed by civil engineers who have not demonstrated the GE specialty examination competency and four-year geotechnical engineering experience that underpin the GE specialty license; a building founded on bearing capacity calculations derived from uncorrected SPT N-values can experience differential settlement that damages the structural frame and requires evacuation; a hillside retaining wall designed without proper Site Class F seismic site classification can collapse during an earthquake, destroying structures and injuring adjacent property owners; and a commercial graded fill pad certified without GE engineering-of-record services can fail under structural loads placed on improperly compacted fill. A Ketchum multiplier of 1.5 applied to the $6,625 lodestar maximum produces an enhanced fee of $9,938. PURE KETCHUM: because there is no concurrent federal claim — Bus. & Prof. Code § 6731 and CCP § 1021.5 are California statutes governed by California fee-shifting law — this enhancement faces no Burlington Northern Railroad Co. v. Dague 505 U.S. 557 (1992) constraint. Drafting the Ketchum multiplier section requires 1.00 hour of Billing Gap 3 time.

The final component of Billing Gap 3 is the fees-on-fees calculation — the recovery of attorney fees for the time spent preparing the fee petition itself. In Missouri v. Jenkins 491 U.S. 274 (1989), the United States Supreme Court held that time spent preparing a fee application is compensable under federal fee-shifting statutes, and California courts have adopted the same rule for CCP § 1021.5: a prevailing plaintiff who enforces an important public right under § 1021.5 is also entitled to recover the reasonable attorney time spent preparing and litigating the fee petition. Fees-on-fees in a § 6731 California Licensed GE matter apply to all 4.00 hours of Billing Gap 3 work — the fee petition drafting (1.50 hrs), the lodestar calculation (0.75 hrs), the Ketchum multiplier analysis (1.00 hr), and the fees-on-fees calculation itself (0.75 hrs). At $300/hr, 4.00 hours of Billing Gap 3 time produce $1,200 in fees-on-fees. At $500/hr, the same 4.00 hours add $2,000. The fees-on-fees component ensures that the fully recovered annual fee reaches $3,975–$6,625 in total — reflecting all 13.25 hours across all three billing gaps — without the attorney absorbing any of the fee petition preparation time as non-recoverable overhead. The GE bearing capacity analysis, seismic site classification, and grading compliance experts retained under Sargon Enterprises v. USC (2012) 55 Cal.4th 747 do not need to opine on the legal standard for fee recovery; the attorney's own fee petition declaration is the evidentiary vehicle for the fees-on-fees claim. Drafting the fees-on-fees calculation and the Missouri v. Jenkins citation block requires 0.75 hours of Billing Gap 3 time. The total Billing Gap 3 time — fee petition drafting (1.50 hrs), lodestar calculation (0.75 hrs), Ketchum multiplier analysis (1.00 hr), and fees-on-fees calculation (0.75 hrs) — sums to 4.00 hours, bringing the complete three-billing-gap total to 13.25 hours and the annual recoverable fee range to $3,975–$6,625 per year at $300–$500 per hour, subject to Ketchum enhancement at the court's discretion.
