Understanding the Model

What Is Design-Build and Why Is It
Better in Ontario?

Design-build is a project delivery method where a single company is responsible for both the design and the construction of a project — eliminating the traditional separation between the design team and the construction team. Instead of hiring an architect, then an engineer, then a contractor and hoping they all communicate effectively — you have one accountable team managing everything.

For Ontario clients, the design-build approach means faster delivery, lower risk, fewer conflicts, and a single point of contact throughout the entire project. MAY Engineering's design-build model is unique because it combines technically trained engineers providing structural engineering with an affiliated construction company — Tomas Construction Services — creating a genuinely seamless concept-to-completion delivery.

A

Traditional Method

Hire an architect. Hire an engineer. Tender to contractors. Manage the conflicts between them. Hope nothing falls through the gaps.

B

The Design-Build Method

One team handles everything — engineering, drafting, permitting, project management, and construction coordination. One contract. One accountable partner. No gaps.

C

The Result

Faster project delivery. Fewer change orders. Lower total cost. Less stress. And one team to call when you have a question — from concept to completion.

Our Process

Concept-to-Completion
Design-Build Process

Ten steps. One team. No handoffs. Every phase managed by engineering-educated professionals.

01

Planning

We begin with a thorough review of your project goals, site conditions, budget, and timeline. This phase defines the scope and sets the foundation for every decision that follows.

02

Design

Our team develops the design concept — from initial sketches through design development. We coordinate architectural, structural, and civil requirements from the start.

03

Drafting

Complete drawing packages are prepared by our experienced drafters — including architectural plans, elevations, sections, and all coordination drawings needed for the project.

04

Engineering

Structural, civil, and specialty engineering is completed by our technically trained team. All engineering is reviewed for Ontario Building Code compliance.

05

Permit Applications

We prepare and submit the full permit application package to your municipality — managing the review process and responding to any comments from the building department.

06

Project Management

Once permits are in hand, our project management team takes over — establishing the construction schedule, managing the budget, and coordinating all consultants and contractors.

07

Construction Coordination

We manage the relationship between all parties on site — ensuring trades are coordinated, conflicts are resolved quickly, and the project stays on schedule.

08

Site Inspections

Our engineers perform regular site inspections throughout construction — verifying that work is being completed to the approved drawings and specifications.

09

Construction

Through our affiliated company, Tomas Construction Services, we can manage or self-perform the physical construction — from foundations through finishes.

10

Project Closeout

We manage the closeout process — deficiency review, occupancy coordination, as-built drawings, and all final documentation needed to close out the project.

The Advantage

Why Ontario Clients Choose
Design-Build with MAY Engineering

One Team.
One Contract.
No Gaps.

The traditional method splits design and construction between separate companies — creating communication gaps, finger-pointing, and costly delays. Design-build puts everything under one roof, one contract, and one accountable partner.

Outcome

Single Point of Contact

One phone number. One team. One person to call when you have a question — from concept through completion.

Faster Delivery

Design and construction phases overlap instead of running sequentially — projects reach completion in less time without sacrificing quality.

Lower Risk

Single-point accountability eliminates the blame game. When the designer and builder are the same team, problems get solved, not passed around.

Better Outcomes

Engineering-educated professionals oversee every phase, catching issues early and ensuring the finished project matches the original vision.
