Construction Management
Owner's-agent CM from feasibility through close-out. Honest budgets, defended schedules, a superintendent on site every day, and weekly reporting your real estate, finance, and design teams can actually use.
Serving Manhattan, the outer boroughs, Long Island, Westchester, and Northern New Jersey.
What we cover
Test-fit pricing, market-grounded square-foot benchmarks, and order-of-magnitude budgets before the design is final, so the proforma stays honest as the program evolves.
Competitive, level bid packages to NYC's best union and merit-shop subcontractors. Scope leveling, qualifications review, and a recommendation backed by reasoning, not relationships.
Master CPM schedules driven by trade input, not wishful thinking. Weekly look-ahead, milestone tracking, and early warning when something is slipping before it becomes a recovery problem.
Disciplined change order process with cost transparency. RFI tracking, PCO review, ASI integration, and monthly cost reports that match how owners and lenders actually read budgets.
OSHA-30 supervision on site, site-specific safety plans, daily JHAs, and active QC of the work in place. A clean site is a productive site, and an injury never makes the schedule.
Weekly OAC meetings, monthly project reports, financial dashboards, and access to the underlying schedule, budget, and submittal log. You see what we see.
How we work
Call (212) 947-6441 or email mahenegan@henegan.com. We sit down with you, your architect, and your real estate team to understand the program, the schedule, and the constraints we have to work inside.
Conceptual estimates, value engineering, site evaluation, long-lead identification. We get the budget and schedule honest before the GMP is signed, so the surprises are small and the answer is yes.
Buy out the trades, run the BIM coordination, sequence the work, keep the site safe, hit the milestones. Weekly OAC meetings, real schedule updates, and a superintendent on site every day.
Punch list, commissioning, sign-offs, O&M manuals, warranties, and the documentation your facilities team needs to actually run the space. We don't disappear after substantial completion.
Pricing
CM fees on NYC commercial interiors typically run 3–6% of construction cost depending on size, complexity, and engagement model. We tailor the structure, agency CM, CM-at-risk, or GMP, to fit how the owner and design team want to work together.
Our fee proposal lays the staffing plan out by role, hours, and rate, so you understand exactly what the CM organization on your project looks like and what it costs.

A construction manager acts as the owner's agent, transparent fees, open-book pricing, and an aligned incentive to optimize the build. A general contractor takes lump-sum risk and delivers a fixed price. For most NYC interiors we run a hybrid CM-at-risk or GMP model, which gives owners the transparency of CM with the price certainty of a GC contract.
The earlier the better. Bringing us in during programming or schematic design lets us help the team test the budget against the proforma, identify long-lead procurement, and avoid late-stage VE that compromises the project. By design development we can be giving you firm pricing on real packages.
Yes. Most of our work is owner-furnished design, we collaborate with whichever architect and MEP team the client has retained. When a client needs help selecting a team or wants a design-build delivery, we have long-standing relationships with NYC firms we trust to deliver alongside us.
Both models work. In agency CM, the owner contracts directly with the trades and we manage the process. In CM-at-risk or GC delivery, Henegan holds the subcontracts. The choice usually comes down to how the owner wants to manage risk and cash flow.
We'll sit down with your team and walk through what the right delivery model looks like for the program, schedule, and proforma.
