"Constructabilityis the extent to which a design of a facility provides for ease of construction yet meets the overall requirements of that facility."

The main challenge is getting both the design and construction team to share a common goal to promote effective teamwork. Each team member must have the right attitude that must start from conceptual planning through field operations.

Direct benefits of a good constructability team include:

Construction planning is made easier Both design and construction costs can be reduced Construction durations may be decreased Better quality can be required and expected Early owner occupancy

Indirect benefits of a good constructability team include:

Building a collaborative team committed to project goals Cross discipline training Transfer of expertise from other projects Constructors better understand design intent, and vice versa Increased innovation in both design and construction Competitive advantage

A general constructability checklist includes:

Provide work areas when practical Verify utility locations Assure utility construction coordination with other Agencies Are pay items in the bid tabulation covered by the specs? Is all of the required work covered by pay items? General Constructability Checklist Provide access to work areas Consider access for routine maintenance in design Consider construction methods that “drive” the design Is weather a factor? Are materials available? Keep design simple and flexible Standardize design elements Do specifications allow work efficiency? Are specifications clear, and conform with current practices? Check local Agency requirements for environmental issues. Which material is more economical? Consider material type available during staged construction. Can access be constructed to remote locations? Minimize restricted areas that eliminate normal equipment use Minimize low production or hand work areas Do Special Provisions fit the job? Strive for simplicity in design Minimize architectural details Consider working areas needs around structures Check for overhead utility conflicts Consider access to structure site Can traffic conflicts be reduced? Are work zones large enough for equipment access? Can emergency vehicles travel thru without delays?
