Body
BACKGROUND: The Hall Park Waterline Replacement project (WA0149) will replace dilapidated 4-inch and 6-inch ductile iron water line and construct a new water line in the greenbelt to loop dead-end water lines on five cul-de-sacs in the area. The project area is generally along and west of 24th Avenue NE and south of Creighton Drive. The project will install approximately 3,100 linear feet (LF) of 6-inch; 2,100 LF of 8-inch; and 880 LF of 12-inch water line in the project area including fire hydrants, gate valves, and household meters. Additionally, public streets and private sidewalks and driveways will be replaced or repaired.
In conjunction with funding provided by the Department of Parks and Recreation, approximately 1,800 LF of drainage swale/trail will be removed and replaced within the green belt south of Creighton between 24th Avenue NE and Montclair Circle.
On August 25, 2009, the Norman Utilities Authority (NUA) approved Contract K-0910-54 with Garver LLC (Garver) and Contract K-0910-55 with Lemke Land Surveying, Inc. (Lemke) to perform on-call design and surveying services, respectively. Lemke provided surveying services while Garver provided preliminary design, final design, bidding, and construction management services.
The Oklahoma Department of Environmental Quality (ODEQ) approved the design plans on November 16, 2010 and the NUA noted receipt of ODEQ Permit WL000014100746 on December 14, 2010.
The advertisement for bids was published in April 2012 and bids were received from four contractors on May 24, 2012. The bidding documents included a base bid for the water line improvements (WA0149) and an alternate bid to include the greenbelt drainage swale improvements (PR0124). Central Contracting Services, Incorporated (Central Contracting) was the low bidder at $452,964 for the base bid and $524,273 for the base bid plus alternates. On June 12, 2012, the NUA approved Contract K-1112-129 with Central Contracting of Norman, Oklahoma.
The contract time began July 23, 2012 with final completion required within 240 calendar days or by March 20, 2013. All waterlines were placed into service and the drainage swale was complete by March 20, 2013.
DISCUSSION: During the construction period, two additions to the project scope occurred as identified in items 1 and 2 below. Additionally, the final adjustment of quantities is included in the change order. Final Change Order Number 1 will incorporate the following changes:
1) Compensate Central Contracting for installing an additional 289 feet of 12-inch waterline and fittings along 24th Avenue NE between Lindenwood and Cottonwood at a cost of $16,665 as directed by staff;
2) Compensate Central Contracting for installing ADA-compliant sidewalks and ramps at six (6) corners along 24th Avenue NE at a cost of $11,360 as directed by staff; and
3) Reconcile the estimated bid quantities to as-built quantities resulting in a deduction of $1,371.70.
The change order will not increase the contract time and will increase the overall contract amount by $26,653.30 to a revised total of $550,926.30; this is an increase of 5.1% for the project. The unit prices for the ADA compliant sidewalks and detectable warning surface were not included in the original scope of this project; as such, Central Contracting agreed to utilize the unit price of these items from the FYE2012 Citywide Sidewalk Construction Project as reflected in the change order. As noted above and shown in the attached change order, the quantities for several unit price bid items will also be adjusted.
As shown on the change order, the Water Fund (project WA0149) will fund $24,562.30 and the Capital Fund (project PR0124) will fund $2,091 of the change order amount. The Fiscal Year Ending 2013 budget for Hall Park Water Line Replacement (WA0149) contains unencumbered funds totaling $22,610 in Construction (account 031-9683-462.61-01). To fully fund the Water Fund portion of this change order, $1,953 is requested to be transferred from the Land account (031-9683-462.60-01) in the same project. The Fiscal Year Ending 2013 Capital Fund budget for Trails: Hall Park Greenbelt (PR0124) contains unencumbered funds totaling $38,801 in Construction (account 50-9985-452.61-01) to fund the parks portion of this change order.
Sodding and other cleanup work has been proceeding since construction was completed on March 20, 2013. All work is now complete and acceptable to both the Department of Utilities and the Department of Parks and Recreation. Staff recommends approval of Final Change Order 1, acceptance of the project and authorization to make final payment of $31,528.72 to the contractor.
RECOMMENDATION: Staff recommends transfer of $1,953 from Land (account 031-9683-462.60-01) to Construction (account 031-9683-462.61-01). Staff further recommends the NUA approve Change Order 1 to Contract K-1112-129 with Central Contracting Services, Inc. increasing the contract amount by $26,653.30 to $550,926.30. Staff also recommends that the NUA accept the Hall Park Water Line Replacement Project and authorize final payment in the amount of $31,528.72 to the contractor.
