end that the cost of poles not installed equals the cost of the Astro brackets installed.
4 HIND; Pavement removal on Sheet B.06 needs two saw cuts. The quantity tabulations only show enough quantity for 1 saw cut. The
detals however, show two cuts are needed. It is agreed that the contractor be paid for only half of the extra saw cut length and the
contractor bear the cost of the other half.

C-2 — Justification for cost(s)
1- Traffic Signalization
a. The radio communications prices appear justified based on City's previous experience with that type of work and equipment. Thi
supplier was also directly contacted the supplier to make sure the prices are justified.

administrative time to come up with the solution.

control per Iowa DOT standards.
