Maintaining Budget & Schedule

You expect to have projects stay on time and within budget; this is why we maintain a larger in-house workforce than other builders our size. We make sure our subcontractors meet our high standards of performance and share our company’s commitment to quality.

The longstanding relationships that LeFrois maintains with employees, subcontractors, suppliers, and government officials have made a real difference in providing cost certainty for our customers.

When we’re completely in control, we can ensure that your project finishes on schedule and within budget.

Our Responsibilities

As your General Contractor, we analyze the project plans with all participants. We also arrange for permits and necessary inspections to ensure that everything is in place before work begins.

Once construction begins, LeFrois is on-site regularly to facilitate all day-to-day tasks, inspect progress, and resolve issues. This way, we are fully knowledgeable to address all your questions and concerns.

Lastly, we’ll walkthrough the completed project with you to make certain that everything you were expecting has been accomplished and that you are fully satisfied.

Design / Build Services

With LeFrois’ Design/Build services, you can have peace of mind knowing your project’s quality and timeline are firmly in control.

We provide personalized designs to guarantee budget accuracy from the very beginning so that all team members function as one unit for a seamless final result. To ensure clarity during each step of progress, we also offer 3D renderings to give an accurate visualization of what is being built.

Issues With Hard Bid

Hard Bid projects have the potential to become costly nightmares when designers fail to anticipate field conditions.

With multiple teams (electricians, plumbers, HVAC, and more) all working separately towards their own goals it can be difficult for a cohesive outcome that matches your expectations.

Benefits of Design/Build

Want to avoid the potential issues caused by Hard Bid?

Choosing Design/Build with LeFrois give you the ultimate oversight of your construction endeavor, from inception to move-in day. When we take total responsibility for a project, we’re able to provide firm control over quality, completion dates, and costs.

Construction Management

Our construction management services grant all parties involved in large-scale projects an efficient and effective view of cost progress, ensuring that stress is kept to a minimum while avoiding unwanted financial surprises.

Commercial Construction

Progressive Contract Benefits

Large projects involving multiple parties can lead to many different expectations. Disagreements can bring costly change orders.

When you choose construction management with LeFrois, it allows us to start working on your extensive project without a contract. By holding off on completing a contract until the final stage of a project, everyone is able to add to the expenses on an as-needed basis.

There are a vast amount of moving parts that go into a massive building. Construction management eliminates stress when something unexpected pops up since a rigid contract wasn’t established. Unexpected needs can be handled much easier when a contract develops along with the project.


When you choose Construction Management from LeFrois, you can expect accurate and detailed construction budgets and schedules.

Prior to construction, we obtain all required occupancy permits. We formulate purchasing strategies and direct all bidding and negotiation activities. We then review and approve all contractors’ submissions and establish procedures for administration of the project, including the approval of construction expenditures.

When construction begins, we inspect the work site on a daily basis to monitor progress and ensure the project will be completed on time and within budget. As the project approaches completion, we finalize all punch list items and close out all subcontracts.

Have a large project riddled with uncertainties?

As a premiere commercial general contractor, our construction management services allow us to start construction before signing a contract. This ensures everyone involved will view costs gradually as the building develops.
