1. What is “Constructability”?
The extent to which a design of a facility provides for ease of construction yet meets the overall requirements of that facility

2. Brehm’s Definition of “Constructability”
“Doing for fifty cents what any damn fool can do for a dollar”

3. Design + $$$ = Solution

4. CHALLENGE
Getting the designers and constructors from diverse cultural backgrounds and different goals to work together effectively

5. ALL ABOUT ATTITUDE! It is an attitude that must prevail through:
Conceptual planning
Design and procurement
Field operations

7. Direct Benefits Construction planning is made easier
Both design and construction costs can be reduced
The construction schedule may be shortened
Better quality can be required and expected
Earlier owner occupation

8. Indirect Benefits
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

9. General Constructability Checklist
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?

10. 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?

11. General Constructability Checklist
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.

12. General Constructability Checklist
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

13. General Constructability Checklist
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

14. General Constructability Checklist
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?
