TRITEC Building Company · Construction Management
TRITEC Building Company is a third-party construction manager for owners across Long Island, New York and the Washington, D.C. region. We join during design to lock in cost, schedule and quality before ground is broken, then hold the whole team to it.
An open-book process refined on Long Island since 1986.

What construction management is
In construction management, the owner involves the builder during the design phase rather than after drawings are complete. As your construction manager, TRITEC represents your interests from the outset by pricing the evolving design, evaluating constructability, establishing the schedule, and securing top regional subcontractors.
Once construction begins, we manage the budget, schedule, trades, quality, and safety. Design and budgeting advance together, allowing teams to evaluate design choices against cost and schedule in real time. This integrated approach improves change management by clarifying the impact of decisions on budget and timeline before final documents are issued. Issues are identified early, not during construction. The owner, architect, and builder collaborate as a unified team rather than as separate parties in a bid process.
Why owners choose CM
01
We price the design at every milestone, so value decisions are made while the design is still flexible.
02
Open-book reporting and shared project software let owners see cost and schedule as they move.
03
Preconstruction forecasting and contingency planning catch issues before they become change orders.
04
Owner, architect and builder aligned from day one, with a single point of contact at TRITEC.
05
Trades are engaged during design, so bid and award move faster than a traditional bid on final documents.
Ways to engage us
We structure each engagement around the owner’s goals, timeline and risk tolerance. Every option runs on the same methodology and the same open books.
| Model | How it works | Best for | Examples |
|---|---|---|---|
| CM at Risk (GMP) | TRITEC joins during design and commits to a guaranteed maximum price. We hold the trade contracts, and every trade is competitively bid. | Owners who need early cost certainty and one accountable builder | Station Yards, Shoregate, The Shipyard, Community Ambulance |
| GMP with shared savings | A capped price, with savings under the cap returned to the owner. | Owners who want a ceiling and a share of the upside | Tower Fasteners |
| Cost plus (open book) | Actual cost plus a fixed fee, with full transparency. | Fast-moving or evolving scopes | Hassel BMW, Audiovox, Eppendorf |
| Agency CM (owner’s representative) | TRITEC manages design, bidding and construction for a fee while the owner holds the trade contracts. | Institutions, public owners and multi-prime projects | Kincora |
Need a different route? The same team also delivers design-build and general contracting.
CM vs. GC vs. design-build
Both build the project. The difference is when the builder is hired, and whose side they are on during design.
The earlier the builder joins, the more of the budget can still be shaped. With TRITEC as construction manager, the GMP is set before the drawings are finished, early work packages can start while design wraps up, and owners can bring us in as early as Planning through our Project Prep services.
| Construction management | General contracting (bid) | Design-build | |
|---|---|---|---|
| When the builder joins | During design | After drawings are complete | At concept, before design |
| How the builder is chosen | Qualifications, approach and fee | Lowest qualified lump-sum bid | Qualifications and a combined proposal |
| Builder’s role | The owner’s advocate, paid a set fee | Delivers the drawings for the bid price | Holds both design and construction contracts |
| When cost is known | Early, refined at each design milestone, then fixed as a GMP | When bids come in | Early, from the design-build proposal |
| Builder’s design input | Constructability and value engineering at 10, 30, 70 and 100 percent | Little or none before the bid | Full, since one team owns the design |
| Books | Open | Closed | Usually open |
| Best fit | Complex projects, firm budgets, owners who want a voice in design | Complete documents, simple scope, price-driven decisions | Speed and a single point of accountability |
A bid can look cheaper on day one. Over the life of a complex project, an early, open-book construction manager usually costs less: fewer redesigns, fewer change orders and fewer delays.
Our CM process
Four phases, each with defined deliverables, from the first budget to final sign-off.
01
A defined scope, control budget and schedule. Constructability reviews and value engineering at 10, 30, 70 and 100 percent design, each priced against the budget.
02
Every trade competitively bid with at least three qualified bidders. Bids leveled side by side, with the owner part of every award. Never price alone.
03
We represent the owner’s interests: on-time completion, budget control and contract conformance. Long-lead items released early, trades coordinated daily.
04
A task is not done until it is done. As-builts, O&M manuals, warranties, systems training, a final cost report and the Certificate of Occupancy.
Optional early-stage support: Before preconstruction begins, TRITEC can also help owners with site feasibility, entitlements and approvals, and defining the project program.
Methodology and project controls
Our project controls system tracks budget, schedule, documents, and meetings and reports on every job. The owner sees the same data our team and the trades see.
A control budget built on historical data and subcontractor benchmarking, updated at every design stage. Deviations go to the owner with a recommended fix, and monthly reports track open RFIs, proposed changes and executed change orders.
A baseline schedule built with the design team and trades and reviewed weekly with the architect and owner. Two-week look-aheads keep the trades focused, and long-lead items are tracked from day one.
Submittals, RFIs and change requests logged with “ball in court” accountability. Daily logs, meeting minutes and project photos live in one system.

The professionalism of TRITEC in addressing all our concerns turned what could have been a difficult and stressful undertaking into an almost effortless and pleasurable project.
John F. Napurano, United States Postal Service
The simple thing to say would be the project will be done on time and probably under budget, but my thoughts and feelings go way beyond that.

A construction manager joins the project during design and works on the owner’s behalf through completion. TRITEC Building Company prices the design as it develops, reviews constructability, builds the schedule, competitively bids every trade, and then manages construction: budget, schedule, subcontractors, quality and safety.
A general contractor is usually hired by bid after the drawings are complete, with a price fixed against those drawings. A construction manager is hired on qualifications during design, works for a set fee with open books, and shapes cost and constructability before the design is final.
In CM at Risk, the construction manager commits to a guaranteed maximum price (GMP) and holds the trade contracts. The owner gets early cost certainty and one accountable builder, and savings below the GMP can be shared with the owner.
The CM fee is set up front and every trade is still competitively bid. Early pricing and value engineering reduce redesign, change orders and delays, so the final cost of a complex project is often lower than a bid that looked cheaper on day one.
As early as possible, ideally before the design team is hired. Our Project Prep services cover site feasibility, entitlements, programming and A/E selection, when the biggest cost and schedule decisions are made.
No. TRITEC Building Company works for outside owners as a fully third-party construction manager, including healthcare systems, manufacturers, hotel owners, senior living operators, schools and public agencies.
No. We act as the owner’s advocate and competitively bid every trade to the region’s best subcontractors, so there is no conflict of interest in who gets the work.
Our home base is Long Island, with work across Nassau and Suffolk, New York City, Westchester, Connecticut, Florida, and the Washington, D.C. region including Northern Virginia.
