The Four Phases of the Construction Process
3
Interfacing the Supervisor with the Estimate

• Supervisor should meet with the estimator during
  the bid preparation and provide construction
  productivity information to the estimator.
• The supervisor should review the estimate to
  identify the vital few and the useful many.
• Supervisor reviews contract drawings and
  specifications to determine base bid work and
  potential change order work.
• Supervisor reviews project supplementary
  conditions to identify unique project clauses
  that may cause the supervisor difficulties if
  they are overlooked.
• Supervisor should sign off that pre-planning
  tasks have been performed.

4
Criteria for Identifying the Vital Few

• Cost of the work
• Risk or variation in the production process
• Work tasks that dictate or drive the project
  schedule
• Work tasks the firm and supervisor have seldom
  done previously

5
Pre-Planning Production Budgets(1. Calculate
needed production per day)

• Quantity of work to perform 20,000 sfca
• Divided by number of work days 10 days
• Equals 2,000 sfca/day

6
Pre-Planning Production Budgets(2. Calculate
production rate performed per crew-hour)

• (5 craft-hours) x (10 sfca) (50 sfca)
• (crew-hour) (craft-hour) (crew-hour)

7
Pre-Planning Production Budgets(3. Calculate
production performed by the crew per day)

• (8 crew-hours) x (50 sfca) (400 sfca)
• (day) (crew-hour) (day)

8
Pre-Planning Production Budgets(4. Calculate
number of crews required)

• (2,000 sfca) divided by (400 sfca) (5 crews)
• (day) (day/per crew)
