Construction Project Delivery Methods Used in New York
Project delivery methods define the contractual and organizational structure through which an owner, designer, and contractor relate to one another from project inception through substantial completion. In New York — where public construction contracts are governed by state procurement law and commercial renovation and high-rise work operate under the New York City Building Code and state Department of Labor regulations — the choice of delivery method carries direct consequences for schedule, cost risk, and regulatory compliance. This page identifies the primary delivery methods used in New York, explains how each functions, and defines the boundaries that distinguish one from another.
Definition and scope
A project delivery method is the system that allocates responsibility for design, construction, and risk among the project's primary parties. The four methods in active use across New York commercial and public construction are:
- Design-Bid-Build (DBB) — owner contracts separately with a designer and a contractor; the contractor is selected after design is complete.
- Design-Build (DB) — a single entity holds contracts for both design and construction.
- Construction Manager as Agent (CMa) — an independent construction manager advises the owner and manages multiple prime contracts on the owner's behalf.
- Construction Manager at Risk (CMaR) — the construction manager holds subcontracts directly and guarantees a maximum price.
A fifth structure, Integrated Project Delivery (IPD), uses multi-party agreements to share risk and reward among owner, designer, and contractor simultaneously, though its use in New York remains concentrated in complex healthcare and institutional projects.
Scope of this page: Coverage applies to construction projects located within New York State and subject to New York State law, New York City Administrative Code where applicable, and relevant federal overlay programs. It does not address project delivery structures in other states, federal agency procurement outside New York, or private residential construction governed solely by New York's one- and two-family dwelling code provisions. For details on licensing obligations tied to each delivery method, see New York Construction Licensing.
How it works
Design-Bid-Build proceeds in three sequential phases. The owner engages an architect or engineer of record under a separate professional services agreement. Once construction documents reach a defined completion threshold — typically 100% construction documents — the project is advertised for competitive bids. On public projects, New York State Finance Law §135 (New York State Legislature) mandates separate prime contracts for general construction, plumbing, HVAC, and electrical work on projects above applicable thresholds, a requirement that adds coordination complexity absent in private work.
Design-Build collapses design and construction into a single contractual entity. New York State authorized DB for state agencies through the Accelerated Renewable Energy Growth and Community Benefit Act (2020) and has expanded its use to transportation and infrastructure through the New York State Department of Transportation. Under DB, the owner defines performance requirements in an Request for Proposals; the DB entity assumes design liability that would otherwise rest with the owner's separate architect. For a focused treatment, see New York Design-Build Construction.
CMa preserves the owner's direct contractual relationship with each trade contractor. The construction manager provides preconstruction scheduling, cost estimating, and constructability review, then manages contractor coordination during construction — all as the owner's agent, without holding construction contracts directly. This model is common in complex institutional projects where owners want maximum transparency.
CMaR shifts cost risk to the construction manager through a Guaranteed Maximum Price (GMP). The CM holds subcontracts, absorbs cost overruns beyond the GMP, and typically shares savings below the GMP with the owner under a predetermined formula. New York's public sector has adopted CMaR most notably through the Metropolitan Transportation Authority's capital programs.
Common scenarios
Public infrastructure and transit: The MTA and New York State DOT use DB and CMaR to compress schedules on projects where sequential DBB would add 12–24 months of pre-bid design time. New York infrastructure construction projects frequently cite schedule compression as the primary driver.
New York City commercial high-rise: Large commercial towers in Manhattan typically use CMaR. The construction manager is brought in during schematic design at 30–50% design completion to run early trade-contractor packages — excavation, foundation, structural steel — before full design is complete, a practice called "fast-tracking."
Institutional and healthcare: Hospital and university projects often use CMa when the owner's facilities department has deep internal capacity and wants to maintain direct contracts with specialty trades. Infection control and phased occupancy requirements make owner-controlled sequencing advantageous.
Public school construction: The New York City School Construction Authority (SCA) operates under its own procurement rules and has used CMaR for multi-building capital programs. DBB remains the baseline for smaller individual school projects subject to standard public bidding.
Decision boundaries
Choosing among these methods depends on four factors: risk tolerance, schedule requirements, design complexity, and regulatory constraints.
| Factor | DBB | DB | CMa | CMaR |
|---|---|---|---|---|
| Owner risk (cost) | High | Low–Medium | High | Medium |
| Schedule compression | None | High | Moderate | High |
| Design control | Maximum | Limited | Maximum | Moderate |
| Public sector eligibility (NY) | Always | Agency-specific | Always | Agency-specific |
New York's separate-prime mandate under State Finance Law §135 applies only to DBB on covered public projects; DB and CMaR structures can consolidate trade contracts under a single entity without triggering that requirement.
Safety obligations under New York OSHA standards and Part 23 of the New York Industrial Code apply regardless of delivery method. The general contractor or CM at Risk typically assumes the role of "controlling contractor" for site safety under 29 CFR Part 1926 (OSHA), establishing fall protection, scaffold, and excavation compliance obligations. Under CMa, those obligations must be explicitly assigned in each prime contract because no single entity holds all construction contracts.
Permitting follows the project, not the delivery method. Every structure requires plan approval and permit issuance under the applicable building code — the NYC Building Code for New York City projects, the Uniform Code for the rest of the state — irrespective of whether design and construction are held by one entity or three.
For cost benchmarking across delivery methods, New York construction cost benchmarks provides current per-square-foot ranges by project type and borough.
