Background:
Approval of this item will authorize Change Order No. 1 with Mar-Con Services, LLC. for the League City Pkwy at Brittany Lakes Dr/Fennigan Ln Intersection Improvements Project (TR1101A) in an amount of $42,099.76.
On December 8, 2020, City Council awarded the construction contract for the League City Pkwy at Brittany Lakes Dr/Fennigan Ln Intersection Improvements Project (TR1101A) to Mar-Con Services, LLC. in the amount of $1,735,087.10. Work Change Directive No. 1, in the amount of $47,529.13 was approved administratively on January 4, 2022. This Work Change Directive included the additional cost to utilize high-early strength concrete at Brittany Lakes Dr to reopen the intersection more quickly and the cost of concrete seal slabs to provide a suitable base upon which to construct the wing walls.
To close out the contract, City has been negotiating with Mar-Con Services on few construction changes due to unforeseen field conditions, additional quantities, traffic control, etc. This Change Order No. 1 includes items and amounts which contractor and the City have agreed on and contractor has requested that City consider payment of these items. Change Order 1 includes additional concrete riprap that was underestimated during design; additional cost of traffic control, pavement marking, street signs and electrical work due to field-directed changes; and concrete ditch bottom lining, which was a missed line item.
With approval of Change Order No. 1, the contract amount will be adjusted as follows:
Original Contract Amount $ 1,735,087.10
Work Change Directive No. 1 $ 47,529.13
Change Order No. 1 $ 42,099.76
Adjusted Contract Amount $ 1,824,715.99
The original contract time for completion of construction was 240 calendar days. Work Change Directive No. 1 added 7 calendar days. Change Order No. 1 will add an additional 7 calendar days.
City staff is currently working with the contractor on other close out items to reach an agreement. Items will pertain to construction changes and additional contract time due to high groundwater encountered during construction. Upon completion of negotiations, a Change Order No. 2 will be prepared and brought before Council at a later date.
This project reached final completion on April 1, 2022. Upon approval of Change Order No. 2, the project will be closed out.
