Our Responsibilities
We are responsible for turning an architect's design and a project owner's visions into reality. Whether we are building a bank, church, recreation center, school, library, medical building, retail space, commercial office building or other project ... and whether it is a large or small project - We are your partners working to deliver a quality project to you on time and in a cost-effective manner. This is what excellence and integrity in the construction industry is about.
Pre-Construction
We are available to meet with project owners and architects in the pre-construction stage. Our extensive Construction Management and General Contracting Services background is very useful while planning a project. If you feel you need our assistance or input on your upcoming project, call us today. We would be happy to meet with you.
Our Commitment to Technology with C-bid Process
As part of the Construction Management and General Contracting Services process we signed up for the C-bid system in 2001. We were the first major General Contractor in the Denver area to go online with the bid process for sub-contractors. What makes our commitment to this technology exceptional is that we do not charge our subs to access our C-Bid system nor do we make them purchase additional software.
