Body
Dear Sir:
On September 2, 2010, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 07-168-3P Scum Concentration, Centrifuge Building, Preliminary & Imhoff Tanks, Elevator Improvements, Diffuser Plates and Trailer Replacement, Stickney Service Area, LASMA, to IHC Construction Companies, LLC, in an amount not to exceed $23,544,400.00. The scheduled contract completion date is September 16, 2012.
As of November 4, 2011, the attached list of change orders has been approved. The effect of these change orders resulted in a decrease in the amount of $1,026,667.97 from the original amount awarded of $23,544,400.00. The current contract value is $22,517,732.03. The prior approved change orders reflect a 4.36% decrease to the original contract value.
Item 1: According to the contract plans, the sluice gate stems were to be installed through existing openings below the hand-operated floor stands. While completing this work, the contractor discovered 11 locations where the centerline of the existing sleeve through the slab was not in alignment with the sluice gate at the bottom of the tank, making it impossible to complete as shown in the contract drawings. After notifying the engineer of the problem, the contractor completed the work by coring new openings in the concrete. This work was needed to allow for proper installation of the sluice gate stems. This work is completed. The contractor proceeded at his own risk with this work as determined in his own best interest in executing the overall contract. The contractor submitted an extra work claim (CCO-017) in the amount of $12,868.90 for this work. The engineer reviewed the submitted information, found it to be reasonable, determined it to be extra to the contract, and stated via correspondence 368, that the Engineering Department would recommend its approval.
Item 2: During the coring of the new holes for the alignment of the sluice gates at the bottom of the tank, the contractor encountered and severed some electrical conduit. Before starting the coring work, the contractor requested drawings, but none were available that showed the location of the conduit. The contractor used ground penetrating radar and x-ray devices to locate items embedded in the concrete but only rebar was detected. This conduit needed to be repaired immediately due to its importance to plant operations. This work is completed. The contractor proceeded at his own risk with this work as determined in his own best interest in executing the overall contract. The contractor submitted an extra work claim (CCO-019) in the amount of $5,235.62 for this unforeseen work. The engineer reviewed the submitted information, found it to be reasonable, determined it to be extra to the contract, and stated via correspondence 383, that the Engineering Department would recommend its approval.
It is hereby recommended that the Board of Commissioners authorize the Director of Procurement and Materials Management to execute a change order to increase Contract 07-168-3P in an amount of $18,104.52 (0.08% of the current contract value) from an amount of $22,517,732.03 to an amount not to exceed $22,535,836.55.
Funds are available in Accounts 401-50000-645750 and 645780.
