Construction Management
- Owner's like to have control over their own project, but know the process can be overwhelming. This is where our Construction Management program is the best construction solution. The Cowen Team will manage the planning, design, construction and day to day operations of the project. The Owner can still have the financial controls.
Program & Project Management
- More than one project at a time - No problem for the Cowen Team! We can provide our proven successful process of standard technical and managerial expertise for simultaneous projects. Our Company can handle the day to day management & administration, financial responsibilities, logistics and overall project coordination. The Owner can sit back & relax knowing their project is in the capable hands of Cowen.
Design-Build
- Sometimes it can be easier to deal with just One contact. Cowen Construction has a team of individuals that can not only design the best construction project for our clients, but can build it as well. Cowen works with you on a complete design and budget from conception to completion. Our Owners have full input and knowledge and know how much money will be spent and when the project will be complete before it ever begins!
General Contracting
- After the Owner and Architect have prepared plans, Cowen reviews the information and obtains pricing from the many subcontractors and suppliers that will be needed. By bidding the various areas, the lowest price is obtained and passed along to the Owner. Cowen makes the final selections and begins on constructing the project you have always dreamed of!
