Analysis
On April 7, 2015, the City of Grand Prairie awarded a construction contract to S.J. Louis Construction of Texas, Ltd. in the amount of $2,185,279.40 and approved a 5% contingency of $109,263.97 for a total of $2,294,543.37 for the Avenue K Street Relief Trunk Sewer construction project.
The current Change Order/Amendment No. 5 in the net amount of -$59,597.20 provides for several outstanding items included as part of the re-alignment of the new wastewater main as well as the reduction in the overall amount of work by ending the project at the corner of Westpark Drive and Avenue K. Construction on this project was to begin in mid-May 2015 but due to the heavy rainfall received in the month of May, construction did not begin until mid-June 2015. Due to the depth of the proposed wastewater line and several significant changes in field conditions, several bid items required revisions. The major change in field conditions is the presence of several telecommunication lines that were previously unknown by the design engineer as well as City staff and were not discovered until the contractor began construction in the area. This necessitated a change in the wastewater line alignment, placing it under the median and pavement of the westbound lanes of Avenue K for approximately 1,500 feet. In addition, it was also determined during construction that what was previously believed to be a City wastewater main adjacent to Bell Helicopter’s property at Avenue K and Westpark Drive is actually a private wastewater line on Bell Helicopter’s property and is thus their responsibility for maintenance of this line. The decision was made amongst the City, the Engineer, the Contractor, and Bell Helicopter that this project would now terminate at the corner of Westpark Drive and Avenue K, which is the location where Bell Helicopter’s private wastewater line enters the City’s wastewater system.
Change Order/Amendment No. 5, incorporating the reduction in the scope of work as described above and some additional quantity changes as a result of the substantially completed project, results in the following amounts:
Total Change Order No. 5 Increases: $128,157.20
Total Change Order No. 5 Decreases: -$187,754.40
Total Cumulative Amount for Change Order No. 5: $315,911.60
Total Net Change In Contract for Change Order No. 5: -$59,597.20
Change Order. No. 1 in the net amount of $10,830 is for pre-construction TV inspection of the existing wastewater mains.
Change Order. No. 2 in the net amount of $4,790 is for the extension of a bore by an additional 10 linear feet.
Change Order No. 3 was a time extension.
Change Order. No. 4 in the net amount of $183,563.30 was for the re-alignment of the wastewater main to a location within the pavement limits of Avenue K in order to avoid utility conflicts along the pipeline alignment proposed in the original construction contract.
City staff recommends this change order to resolve the remaining project scope changes and prepare the project for closeout. The overall project completion date for this construction contract is March 31, 2016, and the only outstanding work remaining is to establish 80 percent of the hydroseeding in the areas disturbed by construction before closing the project.
