Consulting Agreement for Construction

The unique risks of construction consulting

Three risks define this industry. First, professional licensing. A consultant reviewing structural details, sizing HVAC equipment, or stamping electrical drawings without a PE license commits unauthorized practice in every state. State boards (e.g., NCEES model law, Texas PELS Act, California PELS Act) have jurisdiction to issue cease-and-desist letters, refer for criminal prosecution, and notify the contractor's insurance carrier. The consulting agreement should expressly state the consultant is NOT performing services requiring a license, or if licensed, attach the license number and jurisdiction.

Second, site safety and multi-employer liability. OSHA's multi-employer worksite policy (CPL 02-00-124) makes any "controlling," "creating," "exposing," or "correcting" employer citable for violations. A consultant who points out a fall hazard and tells a foreman to "fix it" may have become a controlling employer. The Solis v. Summit Contractors line of cases held that GCs can be cited for subcontractor violations they had authority to correct. The contract should clarify the consultant has no safety direction authority unless that is the actual scope.

Third, indemnity and risk transfer. 38 states have anti-indemnity statutes restricting how broadly construction parties can shift liability. California Civil Code 2782 voids "Type I" indemnity (indemnifying for the indemnitee's sole negligence). New York General Obligations Law 5-322.1 voids any agreement requiring indemnification for the promisee's own negligence. Texas Business & Commerce Code 130.002 voids broad-form indemnity in construction contracts. The consulting agreement must mirror what is enforceable in the project jurisdiction.

The Spearin doctrine (United States v. Spearin, 248 U.S. 132 (1918)) is a fourth fault line. When the owner gives the contractor defective plans and specs, the owner impliedly warrants their adequacy and the contractor is not liable for the defect. A consultant who reviews plans for the owner may, depending on scope, shift or assume part of that risk; the contract should be explicit about whether the consultant's review is a warranty.

Industry-specific clauses to include

• Professional Licensing Representation: Either (a) consultant is licensed PE/RA in [state] with license number [X], or (b) consultant is NOT performing services requiring a professional license and any work that would require licensure is excluded; covers state engineering board exposure.
• OSHA Multi-Employer Disclaimer: Consultant has no "controlling employer" authority under OSHA CPL 02-00-124, will not direct or supervise trades, and will report observed hazards in writing to the GC's competent person rather than to workers; reduces multi-employer citation exposure.
• Means and Methods Exclusion: Consultant is not responsible for construction means, methods, techniques, sequences, or procedures, or for safety precautions and programs incidental to construction (mirrors AIA B101-2017 §3.6.1.2 and ConsensusDocs language).
• Standard of Care: Services performed with the degree of skill and care ordinarily used by similar construction consultants in the same locale; expressly NO express warranty of fitness, success, or compliance with plans (the courts will not imply more if the contract is clear).
• Limitation of Liability (jurisdiction-tested): Liability capped at fees paid or insurance limits, whichever greater, but drafted to comply with state anti-indemnity statutes — in CA add the 2782 carve-out for sole negligence; in NY mirror 5-322.1 partial-comparative-fault structure; in TX confirm Bus & Com 130.002 anti-indemnity compliance.
• Indemnity (intermediate form, not broad): Each party indemnifies the other for claims arising from its own negligence or willful misconduct in proportion to its fault; avoid broad-form "regardless of fault" structures that void under most state anti-indemnity laws.
• Insurance Schedule: Professional Liability / E&O $1M/$3M (higher for design-adjacent work); General Liability $1M/$2M (occurrence form) naming owner/GC as additional insureds via ISO CG 20 10 + CG 20 37 endorsements; Auto Liability $1M; Workers' Comp per state statute; Umbrella $5M+ on large projects.
• Prevailing Wage / Davis-Bacon Compliance: On federally funded jobs (40 USC 3141), federally assisted jobs (Davis-Bacon related acts), or state public works subject to little-Davis-Bacon laws, consultant complies with applicable wage determination and provides certified payroll records on request.
• BIM & Project Data Rights: Owner gets a project-specific license to use BIM models, schedules, cost estimates, and reports for the named project; consultant retains pre-existing methodology, scripts, and templates; references ISO 19650-2 if BIM Level 2 is required.
• Lien Waiver / Notice Compliance: Consultant complies with state mechanic's lien notice statutes (e.g., CA Civil Code 8200 preliminary 20-day notice; TX Property Code 53.252 second-month notice) where the consulting services may be lienable.
• Termination & Suspension: Owner/GC may terminate for convenience or suspend on 7 days' notice (mirroring the prime contract); consultant compensated for work performed plus reasonable demobilization, not lost profits on unperformed work.

Common mistakes in construction consulting agreements

• Letting an unlicensed consultant "review" drawings. Saying "just take a look" at structural calcs is unauthorized practice in most states. Either bring in a licensed PE under their seal, or scope the consultant to non-engineering review (constructability, cost, schedule).
• Broad-form indemnity in California, New York, Texas, or any of 35+ other states. The clause is void or unenforceable in whole or part. Use comparative-fault intermediate-form language.
• Telling the consultant to direct subs on site. One Slack message of "tell that crew to don their fall arrest" can convert the consultant into a controlling employer under OSHA's multi-employer policy. Route safety direction through the GC's competent person.
• Not naming additional insureds with the right endorsements. ISO CG 20 10 covers ongoing operations; CG 20 37 covers completed operations. Both are required for owner/GC additional insured status. A bare "additional insured" certificate of insurance without the endorsements is not enforceable.
• No teaming with the prime contract terms. If the prime is AIA A102/A201, the consulting agreement should mirror Article 3 services definitions and Article 13 dispute resolution to avoid procedural traps in claims.
• Forgetting state mechanic's-lien notices. A consultant who fails to send the 20-day preliminary notice in California (Civil Code 8200) or the second-month notice in Texas can lose lien rights entirely on unpaid fees.
• Open-ended schedule/cost advice without disclaimers on labor and materials volatility. Post-2021 lumber and steel volatility, plus 2024–2025 tariff shifts, mean cost estimates need express assumptions about pricing, lead times, and tariff regime; otherwise the consultant absorbs the risk.

Regulatory landscape

Federal: OSHA construction standards at 29 CFR Part 1926 (fall protection 1926 Subpart M, scaffolding 1926 Subpart L, excavations 1926 Subpart P, silica 1926.1153, electrical 1926 Subpart K, and the 2024-effective heat illness rulemaking under 1926 Subpart D); Davis-Bacon Act (40 USC 3141 et seq.) for federally funded construction; Davis-Bacon related acts for federally assisted projects; Contract Work Hours and Safety Standards Act (40 USC 3701) for overtime on federal jobs; Miller Act (40 USC 3131) for payment and performance bonds on federal projects $150,000+.

Local: building codes (IBC adoption with state amendments); permit and inspection regimes; project labor agreement requirements on certain public jobs; storm runoff and erosion control under municipal MS4 permits.

Industry standards: AIA documents (B101-2017 Owner-Architect, B102/B132 alternative, A101-2017 Owner-Contractor Stipulated Sum, A102/A103 GMP, A201-2017 General Conditions); ConsensusDocs (200 Series Owner-Contractor, 800 Series Subcontracts); EJCDC (Engineers Joint Contract Documents Committee) E-Series for engineering services. ISO 19650-1, -2, -3 for BIM information management. ANSI/ASSP A10 series for construction safety. ASTM standards for materials testing. LEED v4.1 / LEED v5 for green building if certification is in scope. WELL Building Standard if health-and-wellness certification is in scope.
