Construction Design Contract Template: Complete Guide for Design-Build Projects 2025
Master construction design contract templates for design-build projects. Learn key clauses, risk allocation, and best practices for integrated design and construction agreements.
A well-crafted construction design contract template is essential for any project that combines design and construction services. Whether you're pursuing design-build delivery, hiring an architect as a design-build contractor, or structuring a CM at-risk arrangement with preconstruction services, the right contract protects all parties and sets clear expectations.
This guide covers everything you need to know about construction design contracts: the different types, essential elements, standard forms, and strategies for negotiating fair terms that protect your interests while enabling successful project delivery.
Design-Build Growth
Design-build delivery now accounts for over 45% of all nonresidential construction spending in the U.S. This integrated approach requires different contract structures than traditional design-bid-build, making specialized design contracts essential.
Understanding Construction Design Contracts
Construction design contracts govern the relationship between parties providing design services (architecture, engineering) and those providing construction services. Unlike traditional contracts where design and construction are separate, integrated contracts combine these responsibilities.
- • Architectural design
- • Structural engineering
- • MEP engineering
- • Civil engineering
- • Interior design
- • General contracting
- • Construction management
- • Trade coordination
- • Project scheduling
- • Quality control
- • Design-build
- • CM at-risk with design
- • IPD (Integrated Project)
- • Progressive design-build
- • Bridging
Types of Construction Design Contracts
Single entity provides both design and construction under one contract with the owner.
Advantages
- Single point of responsibility
- Faster project delivery
- Early cost certainty
- Reduced claims potential
Considerations
- Less owner control over design
- Requires clear criteria documents
- Selection process more complex
- Change order pricing less transparent
Construction manager provides design-phase services while design is developed by separate architect.
Advantages
- Contractor input during design
- Owner retains design control
- GMP developed collaboratively
- Schedule acceleration possible
Considerations
- Multiple contracts to manage
- Potential for finger-pointing
- GMP negotiation can be contentious
- Preconstruction fees add cost
Two-phase approach: Phase 1 develops design and pricing, Phase 2 executes construction.
Phase 1 - Preconstruction
- • Programming and criteria
- • Concept design development
- • Cost modeling
- • GMP negotiation
Phase 2 - Construction
- • Final design completion
- • Permitting
- • Construction execution
- • Commissioning and closeout
Essential Contract Elements
Every construction design contract template should include these critical elements:
- Design phases and deliverables (schematic, DD, CD)
- Design disciplines included (architecture, structural, MEP)
- Owner's criteria and design requirements
- Permitting and regulatory compliance responsibilities
- Sustainability/LEED requirements
- Construction work included
- Owner-furnished items
- Site conditions and access
- Quality standards and testing
- Warranty obligations
Design Compensation
- • Fixed fee or percentage
- • Phase-based payments
- • Reimbursable expenses
- • Additional services rates
Construction Compensation
- • Lump sum or GMP
- • Cost-plus with fee
- • Savings sharing provisions
- • Allowances and contingencies
- Design phase milestones
- Permitting timeline
- Construction start and completion
- Phasing requirements
- Liquidated damages provisions
Design-Build Contract Specifics
Design-build contracts have unique requirements compared to traditional design-bid-build arrangements:
The foundation of every design-build contract. Defines what the owner wants without prescribing how to achieve it.
Typically Includes
- • Program requirements
- • Performance specifications
- • Space needs and adjacencies
- • Quality standards
- • Budget constraints
May Include
- • Conceptual design (bridging)
- • Aesthetic requirements
- • Specific equipment
- • Site constraints
- • Sustainability goals
- Prepare complete design documents
- Meet performance criteria
- Obtain necessary permits
- Construct in accordance with design
- Coordinate all design disciplines
- Provide clear design criteria
- Timely review and approvals
- Site access and information
- Payment per contract terms
- Designate representative
Risk Allocation in Design Contracts
Proper risk allocation is critical in construction design contracts. Key risk areas include:
Who bears responsibility when design is deficient?
Traditional Approach
Designer liable for professional negligence standard. Contractor can claim for design errors impacting construction.
Design-Build Approach
Design-builder assumes all design risk. Owner's criteria package becomes baseline for claims.
Who bears risk for unforeseen site conditions?
- Type I (Subsurface): Typically owner risk with adjustment provisions
- Type II (Concealed): Risk allocation varies by contract
- Hazardous Materials: Usually owner risk unless created by contractor
Integrated contracts must address delays in both design and construction:
- Owner-caused delays (decisions, approvals)
- Designer-caused delays (late deliverables)
- Contractor-caused delays (construction issues)
- Force majeure and excusable delays
Standard Form Design Contracts
Several organizations publish standard construction design contract templates:
- A141: Owner-Design-Builder Agreement
- A142: Design-Builder-Consultant Agreement
- A145: Design-Build Amendment (converting traditional to DB)
- B143: Design-Builder-Architect Agreement
- 410: Standard Design-Build Agreement and General Conditions
- 415: Design-Build Amendment
- 420: Design-Build Contractor-Design Professional Agreement
Design-Build Institute of America publishes forms specifically for design-build:
- • Standard Form of Agreement
- • General Conditions
- • Teaming Agreement
- • Progressive Design-Build Agreement
Contract Negotiation Tips
Clearly define the design criteria
Ambiguous criteria leads to disputes. Document all owner requirements before contract execution.
Address ownership of design documents
Clarify who owns the designs and under what circumstances they can be used by others.
Include appropriate professional liability requirements
Ensure adequate E&O insurance for design services portion of the work.
Define the change process clearly
Establish how changes are priced and scheduled, especially for owner-initiated design changes.
Balance indemnification provisions
Avoid broad indemnities that exceed insurance coverage or create uninsurable risks.
Common Design Contract Issues
- • Vague performance criteria
- • Unlimited design liability
- • Missing coordination provisions
- • Unclear approval processes
- • Inadequate insurance requirements
- • No termination provisions
- • Detailed scope definitions
- • Professional standard of care
- • Clear communication protocols
- • Defined decision milestones
- • Appropriate insurance levels
- • Fair dispute resolution
Frequently Asked Questions
In traditional design-bid-build, the owner contracts separately with an architect and a contractor. Design-build combines both under one contract, with the design-builder responsible for both design and construction. This creates single-point responsibility and typically faster delivery.
Design-builders can provide design services in three ways: (1) in-house design staff, (2) subcontracted architect/engineer, or (3) joint venture with a design firm. The design-builder remains responsible to the owner regardless of how design services are provided internally.
Require adequate professional liability insurance, establish clear design criteria documents, include provisions for owner review at design milestones, and ensure the contract maintains a professional standard of care for design services rather than strict liability.
