Our value engineering efforts involve our cost estimators and consultants, and often involve reliable general contractors, subcontractors, and suppliers with whom we have established working relationships. Access, staging, and construction sequences are often important considerations in constructability. Location of mechanical and electrical rooms frequently can impact costs. Alternate products or brand names of equal quality can reduce costs. Metal studs have proven to be less expensive than wood. Steel bracing or wood shear walls may be less expensive than concrete shear walls.
