Report
As a contractor that designs, installs, commissions, and maintains facilities, MacDonald-Miller's engineering staff brings innovation and a practical approach to every design. For us, pure Design-Build has always meant that design and construction are provided by a single company, integrating the approach, and guaranteeing all aspects of the work.
Estimating
Report
It's not just a price, it's a partnership. From the first conceptual layout to the final construction documents, MacDonald-Miller's estimating team identifies our partners' needs and translates that knowledge into an accurate representation of the project's mechanical costs. The tools at our disposal, complemented by our meticulous approach, enable our team to leverage assets developed from engineering, estimating, detailing and fabrication models.The entire MacMiller team uniquely works from the same modeling database.
