Our project management philosophy focuses on developing an interactive and inclusive team relationship between the client and design and construction teams. Preconstruction services are paramount to the process to provide value, savings costs, and informed decision making to the client to achieve budget and design intent as efficiently as possible. We provide planning, estimating, value engineering options, scheduling, and pre-qualification of subcontractors. Sigma develops and monitors budgets and coordinates ordering of long lead-time items. During construction, we oversee the purchase of required materials, subcontractor services, the building, and subsequent successful operation of your project.
