California Structural Engineer Bus. & Prof. Code § 6736 Attorney Fee Petition Mechanics: SE-NNNNN License Verification at search.dca.ca.gov as Primary Welch Anchor (THE ONLY § 6736 Structural Engineer Page — DISTINCT FROM Civil Engineer § 6730, Architect § 5536, and General Professional Engineer § 6762; SEAOC Blue Book Seismic Design Advisory [PURE KETCHUM]; AISC Code of Standard Practice Advisory [PURE KETCHUM]; TWO PRIVATE STANDARDS ON ONE PAGE), CCP § 1021.5 Private Attorney General Mandatory Attorney Fees

Statutory Framework: Bus. & Prof. Code § 6736 and SE Licensure — Structural Engineer Requirements, Scope of Practice, SEAOC Blue Book [PURE KETCHUM], AISC Code of Standard Practice [PURE KETCHUM], and CCP § 1021.5 Mandatory Attorney Fees

California Business and Professions Code § 6736 is the Structural Engineer licensure requirement within the Professional Engineers Act, establishing that the structural design of specified building categories must be signed and stamped by a person holding a California Structural Engineer (SE) license — a designation that requires passage of the California-specific two-day SE examination in addition to the standard 16-hour Professional Engineer examination, plus separate SE-NNNNN license issuance from the BPELSG. The categories requiring SE oversight include: any building over three stories in height used for human occupancy; essential facilities (hospitals, fire stations, police stations, emergency operations centers); all steel moment-frame structures in Seismic Design Category C, D, E, or F; all concrete shear-wall structures in SDC D, E, or F; and any structure where the California Building Code (CBC) requires a licensed SE by reference. § 6785 prohibits unlicensed practice of structural engineering; a violation of § 6736 constitutes unauthorized practice actionable under CCP § 1021.5 when it vindicates a public right affecting safety of building occupants. Primary Welch anchor for all § 6736 fee petitions: BPELSG License Verification at search.dca.ca.gov (SE-NNNNN module).

The BPELSG SE-NNNNN module is authoritative for SE license status, license number, issuance date, renewal expiration, and any disciplinary restrictions. The attorney searches by the defendant’s full legal name and any SE-NNNNN number stamped on the structural drawings to confirm: (1) absence of a valid SE license during the plan-stamping and engineering services period at issue; (2) license expiration date if a prior SE license existed; (3) any disciplinary restrictions or revocations. Secondary Welch anchors are city or county building department permit records (plan-check documents showing who signed structural plans and the license number) and BPELSG enforcement records (prior § 6736 unlicensed practice citations or cease-and-desist orders).

SEAOC SEISMIC DESIGN RECOMMENDATIONS (BLUE BOOK) ADVISORY — THE ONLY PAGE IN THE FEE-PETITION-MECHANICS SERIES WITH A SEAOC BLUE BOOK ADVISORY — PURE KETCHUM: The Structural Engineers Association of California (SEAOC, founded 1957, Sacramento CA) is a private nonprofit professional organization representing structural engineers practicing in California. The SEAOC Blue Book establishes California-specific structural engineering standards. Section 4.04 (Structural System Performance Objectives) requires that structural systems be designed to achieve Life Safety performance in the Design Earthquake (10% probability of exceedance in 50 years, 475-year return period), which means the structure must remain safe for evacuation without collapse. For wood-frame soft-story residential buildings, Section 4.04 requires explicit analysis of the soft-story drift mechanism — the tendency of the flexible lower story (ground-floor parking or open commercial) to concentrate lateral drift — with lateral force-resisting system design that limits story drift to Code-allowable levels; an SE who stamps soft-story residential plans without performing or documenting the soft-story drift check commits a Section 4.04 deviation. Section C-IV (Connection Documentation Standards) requires that structural drawings show all connection force demands (shear, moment, axial) with the corresponding connection capacity schedule; an SE who stamps steel-frame or wood-frame drawings with connection locations but no force demand or capacity data commits a Section C-IV deviation that the structural engineering expert documents in the lodestar declaration. SEAOC Blue Book creates no statutory fee-shifting; it is a PURE KETCHUM advisory standard.

AISC CODE OF STANDARD PRACTICE FOR STEEL BUILDINGS AND BRIDGES ADVISORY — THE ONLY PAGE IN THE FEE-PETITION-MECHANICS SERIES WITH AN AISC CODE OF STANDARD PRACTICE ADVISORY — PURE KETCHUM: The American Institute of Steel Construction (AISC, founded 1921, Chicago IL) is a private nonprofit trade organization representing the structural steel industry. The AISC Code of Standard Practice defines the allocation of design responsibility between the SE and the steel fabricator. Section 4.4.2 (SE Responsibility for Connection Design) specifies that the SE of Record must include in the design documents the type and size of all connections, the connection force demand (maximum shear, moment, and axial demand for each connection), and the minimum weld size and type required; an SE who provides connection locations on structural drawings without specifying force demand and capacity creates an ambiguous division of responsibility that the fabricator cannot resolve without exceeding their authorized scope. Section 9.2 (Fabrication Tolerances) defines maximum permissible out-of-plumb, out-of-straightness, and cross-section dimension tolerances for erected steel members; when structural failures occur, the attorney uses AISC Section 9.2 as the benchmark against which as-built measurements of failed members are compared. AISC Code creates no statutory fee-shifting; it is a PURE KETCHUM advisory standard.

CCP § 1021.5 (private attorney general doctrine) provides mandatory attorney fees to a successful plaintiff who enforces an important right affecting the public interest where the necessity and financial burden of private enforcement make fee shifting appropriate. Structural engineering licensure under § 6736 is a public safety statute protecting life safety of building occupants; a plaintiff who successfully sues an unlicensed SE or a PE who stamped § 6736 structures without an SE designation vindicates a public interest in building safety that is broader than the plaintiff’s individual recovery. CLRA § 1780 provides an alternative fee-shifting theory for structural engineering services rendered to individual homeowners or residential property owners who are consumers.

Three-Track Harm: Soft-Story Seismic Collapse ($285K), Expired-SE Steel Connection Failure ($285K), and Hillside Retaining Wall Overturning ($95K)

• SE STAMPS SOFT-STORY WOOD-FRAME RESIDENTIAL CONDOMINIUM BUILDING PLANS WITHOUT PERFORMING SEAOC BLUE BOOK SECTION 4.04 SOFT-STORY DRIFT ANALYSIS (LIFE SAFETY PERFORMANCE OBJECTIVE IN DESIGN EARTHQUAKE) — INADEQUATE LATERAL FORCE-RESISTING SYSTEM AT GROUND-FLOOR GARAGE STORY — Mw 6.3 EARTHQUAKE — SOFT-STORY MECHANISM — GROUND-FLOOR COLLAPSE — TWO OCCUPANT DEATHS TRAPPED IN COLLAPSED PARKING GARAGE DURING EVACUATION — $285,000 WRONGFUL DEATH. The 4-story wood-frame condominium building (12 units over ground-floor parking) was designed with a soft story because the ground-floor garage had minimal shear walls on three sides to allow vehicle access. SEAOC Blue Book Section 4.04 requires explicit soft-story drift analysis and LFRS design that limits ground-story inter-story drift to 2% of story height under design earthquake lateral forces. The SE stamped the structural plans without performing or documenting the soft-story drift check; the structural drawings showed the ground-floor LFRS (4 plywood shear panels at one end of the building) but omitted the story-drift calculation confirming Code compliance. During a Mw 6.3 earthquake, the soft-story mechanism activated: ground-floor story drift exceeded 8% of story height, the plywood shear panels failed in nailing, and the ground floor collapsed pancake-fashion, trapping two occupants in the parking garage during evacuation. The attorney retains a structural engineering expert to opine on the SEAOC Blue Book Section 4.04 soft-story drift analysis omission and causation of the Life Safety performance objective failure and the two wrongful deaths.
• EXPIRED SE LICENSE (SE EXPIRED 8 MONTHS PRIOR) STAMPS 7-STORY MIXED-USE STEEL MOMENT FRAME STRUCTURAL DRAWINGS WITH CONNECTION FORCE DEMANDS OMITTED FROM DRAWINGS (AISC CODE OF STANDARD PRACTICE SECTION 4.4.2 VIOLATION) — STEEL FABRICATOR DESIGNS BEAM-COLUMN CONNECTIONS WITHOUT FORCE DEMAND DATA — FIELD WELDS UNDERSIZED FOR GRAVITY LOADS — PARTIAL PROGRESSIVE COLLAPSE DURING CONSTRUCTION — ONE WORKER FATALITY — $285,000. The 7-story mixed-use building (steel moment frame, SDC D, Seismic Design Category requiring SE) was designed by a structural engineer whose SE license had expired 8 months before plan submittal; the drawings bore the SE stamp and number but the license was not current (BPELSG SE-NNNNN module would show expired status). The structural drawings showed beam-column connection locations and general type (moment connection) but omitted the connection force demand — the maximum shear, moment, and axial demands for each connection — in violation of AISC Code Section 4.4.2. The steel fabricator, lacking force demand data, designed the field-weld connections using only the minimum weld size specified by AISC Table J2.4 without confirming capacity against demand. During construction, a floor beam-column connection at Level 3 failed under gravity loads (dead load plus construction live load exceeded the undersized field-weld capacity), initiating partial progressive collapse of Level 3 and Level 4 bays. One ironworker died in the collapse. The attorney retains a structural engineering expert to opine on the AISC Code Section 4.4.2 connection force demand omission, the expired SE license violation, and the causation chain from undersized field welds to partial progressive collapse.
• PERSON HOLDING ONLY PE-CE (CIVIL ENGINEER) LICENSE — NOT SE DESIGNATION — STAMPS HILLSIDE CANTILEVER RETAINING WALL STRUCTURAL CALCULATIONS FOR 8.5-FOOT MASONRY RETAINING WALL IN SEISMIC DESIGN CATEGORY D WITHOUT SE LICENSE (§ 6736 UNAUTHORIZED STRUCTURAL ENGINEERING) — SEAOC SECTION C-IV SEISMIC ACTIVE EARTH PRESSURE OMITTED FROM CALCULATIONS — 100-YEAR STORM SATURATION — RETAINING WALL OVERTURNS — NEIGHBOR’S PROPERTY DAMAGED — $95,000. The 8.5-foot masonry cantilever retaining wall was required by the grading plan for a hillside residential lot in a California county with SDC D designation. A retaining wall of this height in SDC D is a § 6736-regulated structure requiring SE stamp for the structural calculations. The party who stamped the calculations held only a PE-CE license (civil engineer designation) without the separate SE designation; the BPELSG search shows PE-CE module but no SE-NNNNN record. The calculations used standard Rankine active earth pressure for the stem and footing design but omitted the seismic active earth pressure increment (delta_PAE per ASCE 7-22 Section 11.8.3), which for SDC D sites adds approximately 30–50% to the lateral load demand on retaining walls. Following a 100-year storm event, the saturated backfill exerted hydrostatic plus seismic-level lateral pressures on the wall; the retaining wall overturned at the footing-stem interface, releasing approximately 80 cubic yards of soil and landscaping onto the neighboring property, damaging the neighbor’s backyard structure, garden hardscape, and irrigation system. The attorney retains a structural engineering expert to opine on the PE-CE/no-SE license deficiency and the SEAOC Section C-IV seismic earth pressure omission as causation of the retaining wall overturning.

Distinct From Civil Engineer (§ 6730), Licensed Architect (§ 5536), and General Professional Engineer (§ 6762)

• DISTINCT FROM Civil Engineer (Bus. & Prof. Code § 6730) — Civil Engineer (PE-CE; BPELSG PE-NNNNN at search.dca.ca.gov) is licensed to perform civil engineering services including site grading, drainage design, horizontal infrastructure, and geotechnical work, but may NOT sign and stamp structural plans for buildings requiring SE designation under § 6736; a PE-CE who stamps structural drawings for a § 6736 building commits unauthorized structural engineering regardless of general PE licensure; the attorney must search both the PE-NNNNN module (confirming only civil PE) and the SE-NNNNN module (confirming absence of SE designation) to establish the license deficiency: § 6736 requires a separate examination and SE-specific license; passing the PE-CE examination and receiving a PE-CE license creates no SE authority.
• DISTINCT FROM Licensed Architect (Bus. & Prof. Code § 5536) — Licensed Architect (California Architects Board C-NNNNN at search.dca.ca.gov) is licensed to prepare architectural documents including architectural drawings for buildings of all types, but may NOT prepare structural design documents (structural calculations, structural drawings) for any building; structural design requires either a PE or SE license depending on building category; an architect who takes responsibility for structural design without a PE or SE license commits unauthorized engineering practice; the § 6736 fee petition requires confirming that the defendant holds no SE-NNNNN (and for smaller buildings, no PE-NNNNN) credential: the architect’s C-NNNNN architectural license covers architectural design; it does not extend to structural engineering calculations or structural plan-stamping authority.
• DISTINCT FROM General Professional Engineer (Bus. & Prof. Code § 6762) — General Professional Engineer (BPELSG PE-NNNNN — any branch designation including mechanical, electrical, chemical, industrial) is licensed for engineering in their specific branch, but no general PE designation (including civil, mechanical, electrical) authorizes structural design stamps for § 6736 buildings without the specific SE designation; a mechanical engineer (PE-ME) who stamps structural calculations for a building qualifies as unauthorized structural engineering: § 6762 establishes the general PE license; only the SE designation added to a PE or granted directly authorizes § 6736 structural engineering stamps.
• DISTINCT FROM Geotechnical Engineer (Bus. & Prof. Code § 6736.1) — Geotechnical Engineer (BPELSG GE-NNNNN at search.dca.ca.gov) is licensed to perform geotechnical engineering services including foundation design, soil bearing capacity analysis, liquefaction assessment, and slope stability analysis, but is NOT licensed to perform structural design of buildings, steel connections, or retaining wall structural calculations without a separate PE or SE designation; a GE who provides foundation design recommendations for a § 6736 building acts within GE scope, but a GE who also stamps the structural drawings for the building superstructure without SE designation commits § 6736 unauthorized practice: GE-NNNNN module at search.dca.ca.gov is entirely separate from SE-NNNNN; the attorney must search both to distinguish geotechnical from structural engineering license scope.

Billing Gap 1 — Pre-Complaint Advisory: BPELSG SE-NNNNN License Verification, Building Department Plan-Check Records, SEAOC Blue Book Section 4.04/C-IV Deviation Analysis, AISC Section 4.4.2 Deviation Analysis (5.25 hrs/yr = $1,575–$2,625)

• Searching the BPELSG License Verification at search.dca.ca.gov (SE-NNNNN module) and cross-referencing building department permit and plan-check records to document the structural engineering license deficiency: confirms absence of a valid SE-NNNNN license during the plan-stamping period; documents the search with timestamped screenshots as the primary Welch anchor; cross-references city or county building department permit records to identify the license number stamped on the structural drawings and the date of plan check approval; identifies any prior BPELSG enforcement actions for § 6736 unauthorized practice.
• Analyzing SEAOC Blue Book Section 4.04 structural system performance objective deficiencies (soft-story drift analysis omission; Life Safety objective not demonstrated) and Section C-IV connection documentation omissions (connection force demand and capacity schedule missing from structural drawings) for each harm track: soft-story collapse track — do the structural drawings include inter-story drift calculations for the soft-story at design earthquake ground motion; is there a lateral force-resisting system analysis showing story drift within Code-allowable limits; steel connection failure track — do the structural drawings include connection force demand tables for each moment connection; is there a field weld schedule specifying weld size based on computed demand; retaining wall track — do the retaining wall structural calculations include seismic active earth pressure increment per ASCE 7-22 § 11.8.3.
• Analyzing AISC Code of Standard Practice Section 4.4.2 connection force demand specification omissions and Section 9.2 fabrication tolerance documentation failures for the steel connection failure harm track: documents the AISC Section 4.4.2 deviation (connection force demand omitted from structural drawings) in structured analysis for the expert declaration supporting the CCP § 1021.5 lodestar.
• Advising the client across three advisory calls: BPELSG registry results, SEAOC/AISC standards analysis for each harm track, and expert strategy for structural engineering and seismic performance analysis.

Billing Gap 2 — Expert Coordination: Structural Engineering Expert and Seismic Performance Expert (4.00 hrs/yr = $1,200–$2,000)

• Retaining the structural engineering expert for all three harm tracks — opining on the SEAOC Blue Book Section 4.04/C-IV and AISC Code Section 4.4.2 deviations and the structural failure causation mechanisms: soft-story collapse track — SEAOC Section 4.04 soft-story drift mechanism analysis; the structural system performance objective failure (Life Safety not achieved at design earthquake ground motion); causation of the soft-story collapse from inadequate LFRS design; correlation of ground-story inter-story drift with observed collapse pattern. Steel connection failure track — AISC Section 4.4.2 connection force demand omission; the undersized field-weld causation mechanism; the partial progressive collapse initiation sequence from connection failure to multi-level bay collapse. Retaining wall track — seismic active earth pressure increment under ASCE 7-22 § 11.8.3; the retaining wall overturning moment calculation with and without seismic increment; causation of overturning from omitted seismic load case.
• Retaining the seismic performance expert for the soft-story collapse harm track — opining on the site-specific ground motion demands and the SEAOC Life Safety performance objective: the seismic performance expert provides: (a) USGS probabilistic seismic hazard analysis for the site confirming design earthquake ground motion parameters (Ss, S1, SMS, SM1); (b) the SEAOC Section 4.04 performance objective framework and the ground-story drift prediction under the design earthquake ground motion; (c) the collapse vulnerability index for the specific soft-story configuration and the expected failure mode under design earthquake loading.

Billing Gap 3 — Fee Petition: Lodestar Declaration, Ketchum Multiplier, and Missouri v. Jenkins Fees-on-Fees (4.00 hrs/yr = $1,200–$2,000)

PURE KETCHUM: no federal statute creates mandatory civil fee-shifting for clients harmed by unlicensed California structural engineering; SEAOC Blue Book and AISC Code of Standard Practice are private standards; full Ketchum contingency multiplier applies on the complete lodestar under CCP § 1021.5.

• Preparing the lodestar declaration from the BPELSG SE-NNNNN license verification (primary Welch anchor) and building department plan-check records (secondary Welch anchor) through settlement or judgment, organized by harm track: documents all time consistent with Hensley v. Eckerhart (461 U.S. 424 (1983)) billing judgment standards; the three-track harm structure (soft-story seismic collapse, steel connection failure, retaining wall overturning) requires separate time allocation entries for each expert coordination strand.
• Preparing the Ketchum multiplier brief under Ketchum v. Moses, 24 Cal.4th 1122 (2001) and PLCM Group Inc. v. Drexler, 22 Cal.4th 1084 (2000): PURE KETCHUM; no federal fee-shifting statute applies; the full contingency enhancement is available because: (1) defendant is an unlicensed structural engineer presenting complex technical causation issues across seismic engineering, steel fabrication, and retaining wall structural analysis domains; (2) SEAOC Blue Book and AISC Code expert advisory analysis requires retention of specialized structural engineering and seismic performance experts; (3) contingent fee engagement with no recovery guarantee justifies the Ketchum multiplier.
• Recovering Missouri v. Jenkins fees-on-fees for all fee petition preparation time through CCP § 1021.5: all petition preparation time is recoverable because CCP § 1021.5 enforces an important public right (structural engineering licensure for building occupant life safety); Missouri v. Jenkins fees-on-fees cover BPELSG registry search, SEAOC/AISC standards analysis, expert coordination billing, and lodestar declaration preparation time.
