Title
Consider and take action on a resolution authorizing Change Order 4 to the contract with G.W. Phillips Concrete Construction, Inc. for Bay Ridge Flood Reduction - Phase 1 (DR 2004), in an amount not to exceed $32,800 (Executive Director of Capital Projects)
Background:
Approval of this resolution will authorize Change Order 4 to the construction contract with G.W. Phillips Concrete Construction, Inc. for the construction of the Bay Ridge Flood Reduction - Phase 1 (DR 2004), in an amount not to exceed $32,800.
This project is the third of four planned projects impacting the Gum Bayou Watershed and Bay Ridge Subdivision. All these projects are designed to help with street ponding and reduce the flooding potential during large rainfall events. This project scope is to raise a section of Bay Ridge Blvd. to avoid sheet flow from SH 96 during a storm event to migrate down into the subdivision.
Summary of Change Orders 1 thru 3 to date which were administratively approved as well as the proposed Change Order 4 being considered:
Change Order 1: After design plans were completed, the waterline being altered as part of the project was taken out of service. This line connected the SH 96 crossing to the water plant site at Bayridge Park. Instead of complete removal from the project, the waterline alignment was modified to allow for a looped system in the neighborhood. $39,238 contract increase.
Change Order 2: Covers remobilization and work performed on the old waterline before the alignment was modified. $0 contract increase.
Change Order 3: Due to the age of the existing waterline in the neighborhood and some unforeseen conflicts underground this change order had to be issue. One additional fire hydrant, removal of a large abandoned underground meter vault in the median, a new gate valve to tie in the existing hydrant at the gas station and a new service bore for the gas station were added. $0 contract increase.
Change Order 4: After City Council award of the construction contract, TxDOT required changes to the traffic control plan for the project. This change in design requires temporarily paving the median at the entrance of the neighborhood along Bayridge Drive. As part of the bid, there were no items for the Contractor to cover these changes. Approval of this change order will create the necessary items for billing. The funding for this change order will come from the “Work Change Directive” budget approved with the original construction contract. The new traffic control plan will allow for more efficient traffic movement through the SH 96 intersection during construction which is scheduled to be completed in June. $32,800 contract increase.
This project is part of the 2019 GO Bond Drainage Program.
