  2. Engineer and Contractor discuss work and payment - pay items or force account
  3. Engineer confirms negotiated items and Equipment Rental Rates for Force Account with Estimating Unit or 651-366-4693.
  4. Engineer completes SA Part A form by hand or with typewriter using large font or print so it can be read through the faxing process.  Use informal language to complete SA Part A

  6. Engineer obtains signatures - Engineer, Contractor or representative and Assistant District Engineer Faxed signatures are acceptable and can be on separate copies of SA Part A
  7. Engineer ensures that SA Tech receives faxed copies of SA Part A with all signatures
