How much a sitework, building or interior improvement costs depends on many factors. Location, municipality, type of building, site conditions, design, timing and schedule are but a few of the factors that affect the cost. Cost Modeling is both Art & Craft in the sense of anticipating both a future design and market environment. The process starts from a conceptual cost study based on a small amount of information to a firm price based on bids for each element of the overall scope of work. Along the path, the accuracy of the Cost Model goes up and the uncertainty goes down.
