Background and Discussion:
The location of the work is in the Fallbrook, Ridgepoint, and Westpoint Subdivisions in the Halls Bayou Watershed. The proposed improvements include installation of new storm sewer system, roadway paving, channel restoration and desilting.
The Change in contract request includes changes due to the following:
• Time extension (Stationing stakes) - Three days are being added to the contract time due to resolving an issue with the initial stationing stake out of the channel which led to loss of time at cost of $0.00 and addition of 3 days.
• Time extension (Elevation correction) - Three days are being added to the contract due to an elevation error noted in the channel that needed Surveyor to re-visit the project at a cost of $0.00 and addition of 3 days.
• Hydro mulch seeding - Additional quantity needed for hydro mulch seeding line item # 52 due to an oversight in updating bid item quantities with an added cost of $33,005.00 and 0 days.
• Swapped Lime Stabilization of Subgrade with Cement Stabilization - To expedite construction, the contractor requested permission for substituting lime stabilized subbase with cement stabilized subbase at no extra cost to Harris County. Added new line item#89 for 5,865 square yard of 6 inch Cement Stabilized Sand subbase, deducted 1365 Tons of Hydrated lime slurry from line item #21, deducted 5,865 square yard of lime stabilized subgrade from line item #22. The total net additional cost is $0.00 and 0 days.
• Field changes due to contract plan revision - There was differences in elevations noted in the field from that shown on the contract drawings. This resulted in the revision of 10 plan and profile sheets of the contract plans. This led to delays with fabrication of concrete structures and impacted the critical path of the project, 114 days were added which led to additional quantities needed for existing line item #16 for site preparation, #66 for traffic control and #60 for SWPPP for the extended duration. Added $72,300.00 and 114 days.
• Addition of 36 inch Corrugated Metal Pipe (CMP) - Due to field conditions encountered in the channel, the project team decided to remove and replace an existing 36 inch diameter CMP. This led to introduction of a new commitment line item on the contract. Added $13,755.00 and 3 days.
Expected Impact:
This project seeks to reduce flooding and strengthen resiliency in Harris County by assisting in the alleviation of structural flood damage to homes in the Fallbrook, Ridgepoint, and Westpoint subdivision.
