Subject:

Construction Manager at Risk (CMAR) Construction Services Agreement No. WA2103.402, with Archer Western Construction, for the Pecos Surface Water Treatment Plant SCADA Upgrades GMP-2

Proposed Motion:

Move City Council award CMAR Construction Services Agreement No. WA2103.402, to Archer Western Construction, for the Pecos Surface Water Treatment Plant SCADA Upgrades GMP-2, in an amount not to exceed $8,360,342.

Background/Discussion:

The Pecos Surface Water Treatment Plant (PSWTP), located at 1475 East Pecos Road, was put into service in 1989 and produces drinking water for the city's residents and businesses. The plant's automation technology, commonly called the Supervisory Control and Data Acquisition (SCADA) system, controls, and monitors the PSWTP and approximately 50 remote facilities. Operational control for the water system relies heavily on automation to reliably communicate within the PSWTP and remote water facilities. Beyond system control, SCADA also captures numerous data points for system analysis and regulatory reporting. The SCADA system has approximately 3,200 inputs and outputs, otherwise known as I/O. The 2019 SCADA Master Plan identified the need to replace the outdated control system that was installed during the original plant construction with modern technologies, bringing it up to current industry standards.

On November 10, 2022, City Council approved Guaranteed Maximum Price No. 1 (also known as GMP-1) for the first phase of this project in the amount of $2,766,254.46 with Quantum Integrated Solutions, Inc. GMP-1 included the procurement of long lead time items. Upon conclusion of GMP-1, Quantum and the City mutually agreed to part ways rather than partner on GMP-2, which includes the (final) construction phase of the project. A Request for Qualifications (RFQ) process was conducted and Archer Western Construction was selected as the recommended vendor to continue the project.

The project scope of work consists of upgrades to the legacy SCADA hardware and software systems at the PSWTP and remote locations and unifying the control hardware across all networks, as well as replacement of control panels and controllers with standardized programmable logic controllers, cabinet replacements, new servers and software, cellular modems, ethernet devices, electrical supply and backup, digital input modules, switches, fiber optic cables and conduit, equipment racks, and mounts. Work also includes routing wiring inside existing conduit, trenching for new conduit, and restoration of affected existing improvements and facilities. The agreement completion time is 600 calendar days following Notice to Proceed.

A related Professional Services Agreement with Jacobs Engineering Group, Inc., for the Pecos Surface Water Treatment Plant SCADA Upgrade GMP-2 Construction Management Services, is also scheduled for this City Council meeting.

Evaluation:

The selection process was followed in accordance with city policy and procedure and state law. Staff recommends agreement award to Archer Western Construction based on qualifications, relevant firm experience, team experience, project understanding, and project approach. Staff reviewed the Guaranteed Maximum Price proposal and determined it to be reasonable.
