Title
Consider and take action on a resolution awarding a construction contract to Vaca Underground Utilities, Inc., in the amount of $193,030, for the repair and restoration of the Bay Area Blvd. sound walls at Alderwood Street as part of the Sound Wall Repair Project (WW1501), and authorizing the expenditure of $23,163 for a Work Change Directive and Material Testing Services budget (Deputy City Manager)
Background:
If approved, this resolution will award the construction contract to Vaca Underground Utilities, Inc. for the repair and restoration of the Bay Area Boulevard sound wall at Alderwood Street.
The purpose of this project is to repair the failed concrete slope paving, located under the Bay Area Boulevard sound walls. The sound walls were constructed by TxDot in 1996, as part of the Bay Area Blvd. Extension Project. Drainage from the residential backyards is flowing under the slope paving, towards Bay Area Boulevard, causing the soil under the slope paving to erode. The sound walls are supported by drilled shafts and are not in danger of collapsing, but continued erosion will cause additional slope paving failure.
The project generally consists of removing the existing slope paving and replacing with a concrete retaining wall. The residential backyards will be stabilized and re-graded to drain over the retaining wall. In addition, the adjacent sidewalks will be removed and replaced due to settlement.
Sealed bids for the project were received November 17, 2015. Vaca Underground Utilities, Inc. submitted the lowest bid in the amount of $193,030. Attached is the City’s engineering consultant’s recommendation of award, along with the bid tabulation.
Staff requests the approval of the award of the construction contract and the authorization of funds, as follows:
1. Construction contract with Vaca Underground Utilities, Inc. in the amount of $193,030
2. Work Change Directive budget in the amount of $19,303 (10% of construction amount) which will allow staff to approve minor field changes to expedite decisions, avoid possible construction delays and/or damage claims by the contractor.
3. Material Testing Services budget in the amount of $3,860 (2 percent of construction amount). The concrete and soil materials, used in this project, require testing in accordance with the contract documents, whereas the City is responsible to employ and pay for services of an independent testing laboratory.
This project is anticipated to take 90 calendar days from the notice to proceed.
