Pre-Construction Services

Our experienced professionals determine how best to approach the physical development and construction process.These services are unique to each client and in line with the specifics of each project.

Our team approach is to work hand in hand with the client and architect throughout the design concept, leaving room for possible schedule adjustments and any challenges that can arise. And we review the documents with you, so everyone understands how the project will come to fruition. You will know the detailed strategy our team will follow to execute a successful construction plan.

Pre-Planning Services

The careful decisions made in this initial phase will be crucial for the success of your construction project. Our team will use our clear understanding of our clients’ needs and strategize to make your construction vision a reality.

During this phase we will discuss location requirements and limitations, such as: any historical value that needs to be preserved, energy or sustainability initiatives that need consideration, and any obstacles that we might need to prepare for.Then we gather materials options, analyze how they effect the estimate and find the subcontractors who can best work with this initial project outline.

Cost Estimating

With 50 years of construction experience, our in-house estimating team turns complex plans into clear, reliable budgets you can trust. By providing accurate, detailed estimates early, we give you confidence in your project’s feasibility and help guide smart decisions before construction begins.

Our estimators work directly with our trusted subcontractors, ensuring every number reflects real-world costs and practical construction methods. This collaboration also allows us to identify cost-saving opportunities and value-engineered alternatives—maximizing quality while controlling expenses.

Having an in-house team means your estimates are fully integrated with the project team, keeping everyone aligned and reducing surprises during construction. The result is a smoother process, informed decisions, and a project delivered on budget, on schedule, and to the high standard you expect.

Project Management

Our Project Managers are the driving force behind every successful project we build. As your general contractor, they lead the construction process with a clear focus on organization, communication, and accountability—so clients always know their project is in capable hands.

From the outset, our Project Managers coordinate schedules, budgets, subcontractors, and on-site operations to keep work moving efficiently and safely. Working side by side with our superintendents, they provide hands-on leadership in the field while maintaining consistent oversight of quality and progress.

Equally important, our Project Managers serve as your primary point of contact throughout construction. They anticipate challenges, communicate clearly, and guide decisions with your goals in mind—delivering a well-managed project and a positive building experience from start to finish.
