"Construction management" is sold three different ways in the DC market, and the differences decide who holds your trade contracts, who owns the schedule, and who pays when the drawings and the budget disagree. Here is what each version actually means for a commercial owner, property manager, or board — and when a $500K renovation needs one at all.
The term covers three distinct arrangements, and firms in the District use all three under the same label. The questions that separate them are simple: who signs the trade contracts, and who carries the cost risk?
CM-agency (CM as advisor). The construction manager works for a fee as the owner's professional, and the owner holds the contracts with the trade contractors directly. The CM plans, bids, schedules, and coordinates, but does not guarantee the price or self-perform the work. This gives an owner maximum transparency and control, and maximum exposure: if a trade contractor fails, that is the owner's contract to sort out. The arrangement sits close to owner's representation, and on small projects the two roles are often the same person.
CM-at-risk (CMAR, sometimes CM/GC). The construction manager joins during design for a preconstruction fee, then converts into the builder: it holds the trade contracts and commits to a guaranteed maximum price (GMP) once the drawings are far enough along to price. The AGC/NASFA guidance on the method describes the GMP as typically finalized near the end of construction documents, after the CM has competitive subcontract pricing for the main trades, with 90 to 95 percent of the cost usually priced and the remainder held as allowances. Cost overruns above the GMP, absent owner-driven changes, are the CM's problem — that is the "risk" in the name.
A general contractor offering preconstruction. Many projects in the $250K to $5M range are not big enough to justify a formal CMAR procurement, and AGC's own paper notes that projects over roughly $5 million are the typical candidates because below that the CM fee can exceed the savings. For smaller work, the practical version of construction management is a commercial general contractor who comes in during design, prices the drawings as they develop, and then builds under a lump-sum or GMP contract. Functionally it is CM-at-risk without the ceremony.
The honest answer is a range, and the AGC/NASFA guide is the source for it: it puts preconstruction services at roughly 1 to 5 percent of project cost and the CM's fee at 2 to 5 percent of estimated construction cost, with general conditions and contingency carried separately. For a $2 million renovation, that is a preconstruction budget in the tens of thousands, not hundreds — and it buys the work that prevents the expensive problems: constructability review, estimate reconciliation against the design, long-lead equipment identification, logistics planning for an occupied building, and permitting analysis before the permit set is finished.
What it does not buy is a lower bid on finished drawings. If your scope is fully designed, straightforward, and competition is your board's priority, hard-bidding the documents to three qualified GCs remains a perfectly good way to buy construction. Construction management earns its fee when the design is still moving, the schedule is tight, the building is occupied, or the systems are technical enough that a builder's input during design will change the drawings.
Occupied buildings. A phased renovation of an operating medical suite, a nonprofit headquarters, or a condominium common area lives or dies on logistics: hoisting, after-hours work, dust control, elevator reservations, and keeping tenants informed. Planning that during design is construction management; discovering it during construction is a change order.
Schedule-driven tenant work. A tenant paying rent on a space that is not open loses money every week. CM-style preconstruction lets permit packages be sequenced and long-lead items ordered before the drawings are complete, the same logic that makes design-build fast. Our tenant improvement page for Washington DC covers the permit side in more detail.
Boards and associations. A condo or co-op board approving a six- or seven-figure envelope repair, garage restoration, or amenity renovation usually needs two things it does not have in-house: someone to translate the engineer's drawings into a real budget, and someone to level the bids. That is CM-agency or owner's-rep work, and the independence question matters — see whether your board needs an owner's representative.
Multi-prime or multi-contractor projects. When an owner has separate contracts for, say, a specialty waterproofing contractor, a mechanical contractor, and a finishes GC, somebody has to own the master schedule and the interfaces between them. That coordination role is the textbook definition of a construction manager.
The District has recently tightened who may call themselves a construction manager. D.C. Law 25-244, the General Contractor Licensing Amendment Act of 2024, establishes a Board of Construction Managers and General Contractors and creates separate license categories for construction managers, commercial contractors, and residential contractors; the Act defines a construction manager as an entity contracted to supervise and coordinate design professionals and multiple contractors, and bars the use of the title without a license. The law's applicability date was tied to January 1, 2026 or inclusion in an approved budget, whichever is later, so confirm the current licensing status of any firm you interview with the Department of Licensing and Consumer Protection rather than taking a website's word for it. Permits in the District are pulled through the Department of Buildings, and in a CM-agency structure the owner should settle up front which licensed contractor is the permit holder of record.
Public owners have their own framework. In Virginia, Code § 2.2-4382 lets local public bodies use construction management only after a written determination that design-bid-build is not practicable or fiscally advantageous, requires a licensed architect or engineer to advise on the method, limits the CM to self-performing no more than 10 percent of the work by cost (the remaining 90 percent goes to subcontractors by competitive sealed bidding to the extent practicable), and requires the CM contract to be signed no later than the end of schematic design. Federal and District agencies operate under their own procurement rules; our government and public sector page covers how OAK fits those.
OAK Builders is a Virginia Class A licensed commercial general contractor based in Falls Church, licensed and insured in DC, Maryland, and Virginia, and we offer construction management in both forms: CM-agency for owners who want an advocate while holding their own trade contracts, and CM-at-risk where we hold the subcontracts and the schedule under a GMP. Our principal, Sean Abadian, PMP and FAC-COR III, spent 15+ years on the owner's side of federal construction, managing $133M+ across 37 projects for GSA, the Department of Defense, and the Library of Congress, including portfolios of ten or more concurrent projects. That background shapes what we actually deliver as a CM:
A baseline schedule you can hold us to. Master schedules built in MS Project or Primavera P6, with a documented critical path, updated monthly against the baseline rather than redrawn to match whatever happened.
Estimates reconciled to the design at each milestone. Schematic, design development, and construction documents each get a reconciled estimate with explicit inclusions, exclusions, and allowances, so the GMP is not a surprise.
Documented QA/QC and reporting owners actually read. One-page monthly reports: cost to date against budget, schedule variance, open RFIs and submittals, upcoming decisions with dates. Federal-grade documentation, sized for a property manager or board.
Independence where it matters. If you hire OAK as your owner's representative or CM-agency on a project, we do not bid the construction on that project. An advisor who may also be a bidder is not an advisor.
Scope-wise, we focus on commercial interiors and renovations, envelope and waterproofing programs, and small capital and facility projects, with estimating and budget management up to about $12 million. You can see everything we self-perform and manage on our services page, and what commercial interiors are costing in this market in our DC-area build-out cost guide.
Whoever you interview, including us: Which contracts will be in my name, and which in yours? When is the GMP set, and what is still an allowance at that point? What is the preconstruction fee, and what deliverables does it buy at each design milestone? Who holds the DC contractor license and pulls the permit? And if you are advising me on this project, are you also bidding it? A firm that answers all five in writing is a firm you can hold accountable.
A general contractor builds the project under a contract with the owner and holds the subcontracts. A construction manager in the agency form advises the owner for a fee while the owner holds the trade contracts; in the at-risk form, the CM joins during design, then holds the subcontracts and guarantees a maximum price, so it ends up functioning as the general contractor with an earlier start.
Often not as a formal CM-at-risk procurement, which AGC guidance notes is usually reserved for larger projects. The useful version for smaller commercial work is a licensed GC providing preconstruction services during design and then building under a lump sum or GMP, or a CM-agency/owner's representative when the owner needs independent bid leveling and oversight.
Under D.C. Law 25-244, the District created a construction manager license and a Board of Construction Managers and General Contractors, with applicability tied to January 1, 2026 or budget funding, whichever is later. Verify a firm's current license status with the DC Department of Licensing and Consumer Protection before contracting.
Not on a project where we serve as CM-agency or owner's representative. OAK holds the trade contracts only under CM-at-risk or general contracting engagements where that is the role you hired us for from the start.
Send us the current set and the number. We'll tell you honestly whether CM-agency, CM-at-risk, or a straightforward GC contract fits — and what it should cost.
