Sigma’s repeat clients rely on the firm for insight and consultation beyond that provided by a general contractor. Sigma offers its perspective at the earliest stages of many projects regarding site selection, design and concept, and will provide accurate conceptual budgeting information to help determine the potential building, site, and offsite construction costs. During preconstruction, Sigma utilizes its vast database of information accumulated over the years to assist clients in creating highly accurate and reliable cost models. These are invaluable when for the team when making decisions about systems, materials, and equipment. This input is derived throughout the process from senior management, estimators, and superintendents (many of whom are LEED Accredited). This is critical to determining the viability of a project through analysis of proposed sites, creating conceptual budgets, and determining appropriate construction systems and schedules. The actual scope of work and constructability of a project can be confirmed and a detailed construction schedule outlined that is realistic and reliable to meet the needs of both owner(s) and design team. This process has successfully helped clients save time, control costs, and increase value.
