Construction Managers

Our construction managers have an in-depth knowledge of the construction industry and profoundly influence the success of each and every project.  WSG construction managers are involved in developing, implementing and achieving the strategic project goals set by the company. They ensure that all WSG policies, practices and objectives are properly interpreted, uniformly enforced, and compliant with all applicable laws and regulations. They oversee operations at every stage of project.

Project Managers

Our dedicated project managers are exceptionally experienced at directing and organizing even the largest of construction projects. Their tireless workmanship is essential in overseeing projects through to completion, and in addressing issues such as structural deficiencies, warranties and as-built close-out documents. 


It all starts with an estimate. Our team's professionalism and experience allows them produce accurate, fair and realistic cost estimates and project budgets.  We’ve developed estimating processes that can seamlessly take projects from conceptual pricing to a guarantee fixed amount with a complete emphasis on efficiency. Extensive quantity take-off, cost analysis, forecasting, vendor relations and evaluation of sub-contractor bids are all part of our full service suite.  

Site Superintendent

Our site superintendents ensure projects run smoothly and efficiently. They are task oriented, and focused on the bigger picture but with an eye for the smaller details. Each site superintendent we employ has a strong background in scheduling, safety, and budgeting. Our site superintendents also receive the latest education and training to ensure they’re up-to-date on new materials and methods within our industry.

Design integration is a critical element in the home addition process. It’s a consideration that includes both the structured layout of the home and the aesthetics of the addition. Each addition we complete is planned to perfection. We ensure a precise match with the property’s floor plans, as well its current interior and exterior design motifs. That’s how our additions become a logical, natural extension of the client’s home.

The ultimate goal for the WSG team is to create a space that functions seamlessly while meeting your exact requirements. During the initial design process, we’ll develop a customized project plan that details the timeline and budget for the completed project. Our commitment to professional communication means homeowners always know the next step in the process and have direct access to qualified project coordinators.
