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). The DI pipe was failing due to acidic soils, causing water outages, water loss and damage to driveways, streets, and yards.
On February 26, 2013, the Norman Utilities Authority (NUA) approved Contract No. K-1213-87 for Project WA0187 with Central Contracting Services, Inc. (CCS) in the amount of $934,225. Due to ongoing work by CCS on other NUA projects, staff granted a postponement of beginning construction, which began during August 2013, with a contract completion time of 180 calendar days.
DISCUSSION: All work was complete June 15, 2014 and the contract is now satisfied. Proposed Final Change Order Number 1 (CO1) increases the contract amount by $14,999 from $934,225 to $949,224, or an increase of about 2%. 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;
· Owner Furnished Meter Boxes: All 303 units were deleted for a decrease of $13,635, since the existing boxes were reused, and no replacements were necessary
Staff desires to publicly commend the employees and management of CCS. Despite almost a year of construction directly impacting the property and residences of over 300 customers and the neighborhood park, some damage to every street in their subdivision, and a significant creek crossing, staff only received a single customer complaint. Even that one was minor in nature, and was immediately resolved by CCS. This superior performance reflects the excellent communication between CCS and the residents, and the care exercised during the work by CCS.
CCS requests, and staff recommends approval of a 147-calendar day time extension due to the delay in starting for the convenience of NUA. Also, staff believes that the extra time delay of completion from April 21, 2014, to June 15, 2014, directly correlates to the care demonstrated by the contractor throughout its performance of the work. The one DI pipe failure in the project area which occurred during the project period was repaired by the contractor at no cost, so no losses were incurred by the NUA.
The Fiscal Year Ending (FYE) 2015 budget for WA0187 includes an unencumbered balance of $46,709.76 for Construction (031-9360-462.61-01), which is sufficient to fund the increase.
RECOMMENDATION: Recommend the NUA approve Change Order No. 1 with Central Contracting Services, Inc., increasing the contract amount by $14,999 to $949,224, accept the Pendleton Drive Area Waterline Project, and authorize final payment in the amount of $24,342.24.
