Ohio Construction Project Delivery Methods
Project delivery methods define the contractual and organizational framework through which an owner, designer, and contractor collaborate to complete a construction project. In Ohio, the choice of delivery method shapes procurement obligations, liability allocation, scheduling timelines, and compliance with state statutes governing public and private construction. Understanding these structures is essential for owners, contractors, and public agencies navigating Ohio's regulated construction environment.
Definition and scope
A project delivery method is the formal system that establishes relationships, roles, and risk distribution among the primary parties to a construction contract. Three principal methods dominate Ohio construction practice: Design-Bid-Build (DBB), Design-Build (DB), and Construction Manager at Risk (CMAR). A fourth method, Construction Manager/General Contractor (CM/GC), overlaps with CMAR and is used in transportation and infrastructure contexts.
Ohio Revised Code (ORC) Chapter 153 governs the procurement of public improvements and directly regulates which delivery methods are available to state agencies, school districts, and political subdivisions. The Ohio Facilities Construction Commission (OFCC) administers guidelines for state-funded building projects and publishes standard contract documents aligned to each delivery method. Private construction projects face fewer statutory constraints but remain subject to Ohio construction contract requirements and applicable building codes.
Scope and limitations: This page addresses Ohio-specific statutes, regulations, and agency frameworks governing project delivery. Federal delivery method requirements — such as those applied to federally funded highway projects under the Federal Highway Administration (FHWA) — fall outside this page's scope, though Ohio Department of Transportation (ODOT) projects may incorporate both state and federal rules. Projects in neighboring states, tribal lands, or federal enclaves are not covered here.
How it works
Each delivery method organizes the design and construction sequence differently:
Design-Bid-Build (DBB)
The traditional model separates design and construction into sequential phases. The owner contracts with an architect or engineer to produce complete construction documents, then solicits competitive bids from general contractors. Under ORC §153.12, most Ohio public improvement contracts above the statutory threshold require competitive sealed bidding, making DBB the default for a large share of public work. Separate prime contracts — for general trades, HVAC, plumbing, and electrical — may be required on Ohio public projects under the "multiple prime" requirement in ORC §153.54.
Design-Build (DB)
A single entity holds contracts for both design and construction services, transferring design risk to the contractor. Ohio authorized Design-Build for state highway and bridge projects through Ohio DOT contractor requirements frameworks. For vertical construction, ORC §153.692 established a pilot program that allowed OFCC-administered state agencies to use DB under defined conditions, subject to legislative approval thresholds.
Construction Manager at Risk (CMAR)
The owner retains a designer separately and contracts with a construction manager who provides preconstruction services and then commits to a Guaranteed Maximum Price (GMP). CMAR was formally authorized for Ohio public school construction under ORC §3318.10 and for other public buildings through OFCC guidelines. The CM assumes the contractor's financial risk once the GMP is established, distinguishing it from an agency CM role where no construction risk transfers.
The numbered phases common across all three methods:
- Project definition — Owner establishes program, budget, and delivery method selection criteria
- Procurement — Solicitation, qualification, and award in compliance with ORC Chapter 153 for public work
- Design development — Varying levels of owner-designer-contractor interaction depending on method
- Permitting — Building permit applications submitted to local building departments under Ohio Building Code (OBC) jurisdiction; see Ohio construction permits overview
- Construction — Execution, inspections, and compliance with Ohio OSHA construction compliance requirements
- Closeout — Certificate of occupancy, final inspections, and warranty activation per Ohio construction warranty requirements
Common scenarios
Public school construction: Ohio school districts using Classroom Facilities Assistance through the Ohio Facilities Construction Commission frequently use CMAR because OFCC standard documents are structured for it and preconstruction collaboration reduces cost risk on complex renovations.
State highway projects: ODOT employs Design-Build for large highway and bridge projects where schedule compression is critical. Ohio's I-270/US 33 interchange reconstruction is an example of a project where DB was used to accelerate delivery.
Municipal buildings and courthouses: Local governments subject to ORC §153.54 typically default to DBB with multiple prime contractors unless they obtain specific authority for an alternative method.
Private commercial construction: Private owners are not bound by ORC Chapter 153 and may select any delivery method. Large industrial or commercial clients often use CMAR or Integrated Project Delivery (IPD) to manage cost exposure on projects exceeding $50 million in construction value.
Decision boundaries
Selecting a delivery method requires evaluating four primary factors:
| Factor | DBB Advantage | DB Advantage | CMAR Advantage |
|---|---|---|---|
| Design control | High owner control | Limited owner control | Moderate owner control |
| Schedule | Sequential, longer | Compressed, parallel | Parallel with GMP certainty |
| Cost certainty | Fixed at bid | Fixed at award | Fixed at GMP |
| Risk transfer | Retained by owner | Transferred to DB entity | Shared to CM at GMP |
Ohio public agencies must verify statutory authority before departing from DBB. Unauthorized use of DB or CMAR on a public project can expose contracts to challenge under ORC Chapter 153. The Ohio public construction bidding process and Ohio construction procurement laws pages address the procedural requirements that apply once a delivery method is selected.
Safety obligations do not vary by delivery method. Regardless of contract structure, all contractors on Ohio projects must comply with Ohio Administrative Code Chapter 4123:1-3 (Ohio OSHA construction safety standards) and the federal Occupational Safety and Health Administration (OSHA) 29 CFR Part 1926 construction safety standards. Permitting and inspection requirements under the Ohio Building Code apply uniformly, and Ohio building codes and standards remain in force independent of project delivery structure.
