CHANGE ORDER NO. ONE TO CONTRACT NO. K-1213-87: BY AND BETWEEN THE NORMAN UTILITIES AUTHORITY AND CENTRAL CONTRACTING SERVICES, INC., INCREASING THE CONTRACT AMOUNT BY $14,999 FOR A REVISED CONTRACT AMOUNT OF $949,224 AND EXTENDING THE CONTRACT 147 CALENDAR DAYS FOR THE PENDLETON DRIVE AREA WATERLINE PROJECT AND FINAL ACCEPTANCE OF THE PROJECT.
Body
BACKGROUND: The Pendleton Drive Area Waterline Project (WA0187) replaced 13,557 feet of ductile iron (DI) water line with eight-inch (8") & six-inch (6") diameter C900 PVC pipe in the Prairie Creek Addition (Map attached).

CO1 is the reconciliation of "as-bid" to "as-built" final quantities. The major cost differences include:
*??10" HDPE Waterline: 65 feet were added under Bid Item 3 for an increase of $9,750;
*??Fire Hydrant Assembly: Six (6) units were added under Bid Item 15 for an increase of $15,000;
