FROM: BRUNO RUMBELOW, CITY MANAGER
MEETING DATE: NOVEMBER 21, 2023
SUBJECT: PURCHASE OF GEOPOLYMER STORM SEWER REHABILITATION
SERVICES IN OAK CREEK DRIVE AND APPROVAL OF
APPROPRIATION ORDINANCE
RECOMMENDATION: City Council to consider the approval for the purchase of geopolymer
rehabilitation services of an arch storm sewer line in Oak Creek Drive
from PM Construction and Rehab, LLC and an ordinance appropriating
the funds.
FUNDING SOURCE: Upon approval of the attached ordinance, funds will be available in the
Storm Drainage Utility Fund for an amount not to exceed $410,000.
BACKGROUND: The corrugated metal arch pipe under Oak Creek Drive between
Timberline Drive to Big Bear Creek, south of Rosecliff Terrace, has been
deteriorating. The bottom of the invert has corroded and the pipe joints
are allowing soil infiltration. This pipe, approximately 910 feet long, will be
rehabilitated with a thin spray -on liner and invert rehabilitation to protect
the integrity of the culvert, as well as prevent soil infiltration to protect
adjacent utility structures and the roadway structure above from sinkholes.
The City proposes to rehabilitate the arch pipes and invert with a
geopolymer liner installed by PM Construction and Rehab, LLC (an entity
of PURIS LLC). PM Construction and Rehab will provide all labor,
materials, supervision and equipment to inspect, clean, apply the
geopolymer material and perform post -lining inspection.
Staff recommends awarding to PM Construction and Rehab, LLC in the
amount of $356,225 and an additional 15% to cover field changes and
inspection related services for a total amount not to exceed $410,000. The
contractor has 90 days to complete the projects after notice to proceed.
This purchase will be made in accordance with an existing interlocal
agreement with Houston -Galveston Area Council (H-GAC) as allowed by
Texas Local Government Code, Chapter 271 and Texas Government
Code, Chapter 791.
Bids were taken by the Cooperative and a contract was awarded to
PURIS LLC. The Public Works and Purchasing staff reviewed the
contracts for departmental specification compliance and pricing and
determined that the contracts would provide the best products and pricing
for meeting the needs of the City.
