L25911.A1 – Approve an amending ordinance to Ordinance 2017-0419, approved on June 7, 2017, 2017, to increase the maximum contract amount from $12,569,673.00 to $15,712,091.25 for contract number 4600014350 between the City of Houston and Denali Water Solutions LLC for onsite water treatment and sludge dewatering and disposal services for Houston Public Works.
Specific Explanation:
The Director of Houston Public Works and the Chief Procurement Officer recommend that City Council approve an amending ordinance to increase the maximum contract amount from $12,569,673.00 to $15,712,091.25 for an agreement between the City of Houston and Denali Water Solutions LLC for onsite water treatment and sludge dewatering and disposal services for Houston Public Works.
The contract was awarded on June 7, 2017 by Ordinance No. 2017-0419 for a five-year term in the amount of $12,569,673.00. Expenditures as of November 29, 2021 totaled $12,569,673.00. Spending authority has been exhausted earlier than anticipated due to an increase in wet hauling, caused by substantial changes in raw water quality. Wet hauling is more expensive due to the dense volume of the material to empty the thickeners (approximately 420,000 gallons per thickener). In such water quality events, the thickeners need to be emptied by wet hauling due to settleability issues with solids. Therefore, an increase to the maximum contract amount is needed to ensure that these services continue through the end of the contract term. All other terms and conditions shall remain as previously approved by City Council.
The Scope of work requires the contractor to furnish all supervision, labor, parts, tools, materials, equipment, supplies, and transportation necessary to perform all operations and maintenance functions of the sludge dewatering system at the Northeast Water Purification Plant (NEWPP) located at 12550 Water Works Way, Humble, Texas 77396.
