Design-Build
One team. One contract. One point of accountability.
Design and construction under a single agreement — a collaborative workflow that puts the people drawing it and the people building it on the same side of the table from day one.
About the Approach
Design-build, where vision and execution never leave the same room.
In the traditional model, an owner hires a designer, then hires a builder, then spends the whole job refereeing between the two. Design-build ends that. Design and construction sit under one contract with one accountable team — so the estimate, the schedule, and the constructability of every decision are on the table while it can still be drawn differently.
For EAJ, it is the way we already like to work. We are builders and developers, so we bring cost and field reality to the drawing board early, catch the expensive problems while they are cheap to fix, and give an owner a single number to hold and a single team to answer for it.
- A single contract for design and construction
- One accountable team from first sketch to final walkthrough
- Early cost and constructability input, fewer change orders
Design + build, one team Design-Build vs. Traditional
The difference is who is accountable — and when.
In the traditional design-bid-build model, the owner sits between two separate firms and absorbs the gaps between them. Design-build closes those gaps.
Traditional (Design-Bid-Build)
- Separate contracts for design and construction
- Builder arrives after the design is already set
- Cost surprises surface late, as change orders
- Owner referees disputes between designer and builder
- Sequential phases stretch the schedule
- Accountability is split when something goes wrong
Design-Build with EAJ
- One contract covering design and construction
- Builder shapes cost and constructability from day one
- Budget is built alongside the design, not after it
- One team owns the outcome — no one to point at
- Overlapping phases shorten the path to occupancy
- A single principal accountable start to finish
What’s Included
Everything under one roof, one contract, one team.
Design-build folds the whole arc of a project into a single agreement. Expand each to see the work involved.
01 Single-Contract Delivery
One agreement covers design and construction, so accountability never falls into the gap between two separate contracts.
- A single point of responsibility for the whole project
- One contract to negotiate, manage, and hold
- No finger-pointing between designer and builder
- Clear scope, budget, and schedule from the outset
02 Integrated Design Coordination
We bring architects, engineers, and design partners to the table and coordinate them against how the building actually gets built.
- Architect and engineering partners managed as one team
- Constructability reviewed as the design develops
- Systems coordinated before they collide in the field
- Owner decisions guided with real cost context
03 Early Cost & Budget Certainty
Because the builder is in the room from the start, the budget is shaped alongside the design instead of discovered after it.
- Live budgeting as the design takes shape
- Value decisions made on purpose, not by change order
- Fewer surprises between estimate and final invoice
- A single number the owner can plan around
04 Streamlined Schedule
Design and construction overlap where it makes sense, so procurement and early work can start before the last detail is drawn.
- Overlapping design and construction phases
- Early procurement of long-lead materials
- Fewer handoff delays between separate firms
- A faster, more predictable path to occupancy
05 Self-Performed & Coordinated Construction
The same principal-led team that shaped the design carries the build, with a vetted bench of trade partners under hands-on oversight.
- Principal-level oversight from groundbreaking to closeout
- A vetted bench of trade partners, coordinated in-house
- Quality held to an in-our-own-home standard
- One team’s name on the finished result
06 Development Partnership
As builder and developer, we can carry an owner’s program from feasibility and approvals all the way to a finished, occupied building.
- Feasibility, site, and approvals support
- Financing and development guidance
- Vision and execution united in one team
- Accountable across the full life of the project
Why Owners Choose Design-Build
Less coordination, fewer surprises, one team that answers.
The value of design-build isn’t just speed — it’s a simpler, more honest way to build.
One point of accountability
When design and construction live under one contract, there is no gap for responsibility to fall into. One team answers for the whole project.
Cost certainty, earlier
The builder prices the design as it develops, so the budget is a decision you make up front — not a surprise revealed after the drawings are done.
A faster path to done
Overlapping design and construction, plus early procurement, compresses the timeline without cutting corners on quality.
Fewer change orders
Constructability and cost are checked while the design is still on paper, heading off the expensive rework that plagues split-contract projects.
A truly collaborative workflow
Designers, engineers, and builders work as one team from the first sketch, so decisions are made together instead of thrown over a wall.
Simpler for the owner
One contract, one team, one number, one principal to call. You get to focus on the vision instead of managing the middle.
The Collaborative Workflow
How a design-build project comes together with EAJ.
Five stages, one team the whole way. Expand any step to see what happens.
- 01
Align
Understand the vision, program, budget, and site.
What happens Less
We start by understanding what you’re trying to build and why — the program, the budget, the site, and the constraints — so design and construction pull in the same direction from the first meeting.
- 02
Design Together
Design develops with cost and constructability in the room.
What happens Less
Architects and engineers develop the design while we price it live and check it for constructability, so every decision is made with real cost and field context — not discovered later.
- 03
Lock Scope & Budget
One documented scope, budget, and schedule.
What happens Less
Scope, allowances, and schedule are documented and agreed before construction, giving you a single number to hold and a realistic timeline built around how the work actually sequences.
- 04
Build
The same team carries it into the field.
What happens Less
The team that shaped the design carries the build, with a principal on site coordinating every trade and keeping you current on cost, schedule, and the next decision.
- 05
Deliver
Punch list closed, keys in hand, one team accountable.
What happens Less
We walk the finished project with you, complete the punch list rather than defer it, and hand over a building one accountable team is proud to put its name on.
About EAJ
Builders and developers — which is why design-build fits us.
EAJ Services started as a father-and-son construction and development firm rooted in New Jersey, with a second office in South Florida. Because we build and develop, we already think about design through the lens of what it takes to deliver it.
That is the heart of design-build: cost, schedule, and craft considered together, from the start, by one accountable team — the way we have always preferred to work.
- Family owned and operated
- Builder and developer — vision and execution united
- A principal accountable on every project

ExploreDesign-Build FAQ
Design-build questions, answered.
Straight answers to what owners and developers ask us most about design-build delivery.
What is design-build?
Design-build is a delivery method where design and construction are provided under a single contract by one accountable team, instead of the owner hiring a designer and a builder separately. It puts the people drawing the project and the people building it on the same side of the table from the start.
How is design-build different from design-bid-build?
In traditional design-bid-build, the owner signs separate contracts with a designer and a builder, and the builder only arrives after the design is finished — so cost and constructability problems surface late as change orders. In design-build, one team handles both, so budget and buildability are shaped alongside the design and one party is accountable for the whole result.
Does design-build save money?
Often, yes — mostly by avoiding it. Because the builder prices the design as it develops and catches constructability issues early, design-build typically means fewer change orders, less rework, and better budget certainty than a split-contract job. You also spend less of your own time coordinating between firms.
Is design-build faster?
Usually. Design and construction can overlap, and long-lead materials can be procured before the last detail is drawn, so the path to occupancy is shorter and more predictable than the strictly sequential traditional model.
Do I still get to choose the design?
Absolutely. Design-build doesn’t take design decisions away from you — it gives you better information to make them. You work with architects and designers just like you would otherwise; the difference is that cost and constructability are in the room as those choices are made.
Can EAJ work with my architect?
Yes. We can bring our own design partners or collaborate with an architect you already trust, coordinating the whole team under one accountable contract. Either way, we manage the design-to-construction handoff so it doesn’t become your problem.
What types of projects suit design-build?
Commercial, institutional, residential, and multi-unit developments all suit design-build, especially when an owner values a single point of accountability, budget certainty, and a faster schedule. If you’d rather hold one team responsible than referee two, it’s a strong fit.
Who is accountable if something goes wrong?
One team — us. That’s the point of design-build. There’s no gap between designer and builder for responsibility to fall into, and no dispute for you to mediate. A single principal answers for the project start to finish.
What areas do you serve for design-build?
New Jersey, New York, and South Florida, with offices in Matawan, NJ and Delray Beach, FL. For the right project, we’ll travel.
