Item # 11.

Council Meeting 2023

Meeting Date:	11/08/2022
Department:	General Services
Pillars:	Excellence in Asset Management
Milestones:	Effectively utilize and promote the Silver Line development with a first mile/last mile solution

AGENDA CAPTION:

Consider Action on a Resolution Approving an Agreement for Professional Services Between the Town of Addison and McKinstry Essention, LLC to Perform Professional Services for Phase I and Phase II Generator Assessment and Replacement Design for Fire Station 1 and Police Department Facility Generators and Authorizing the City Manager to Execute the Agreement in an Amount Not to Exceed $99,070.

BACKGROUND:

An Asset Management System (AMS) is utilized to track the Town's facility and fleet assets. Staff reviews and evaluates the condition of the assets on an annual basis to determine which assets warrant replacement. A review of the Fire Station 1 and Police Department facility generators determined that these items had exceeded their useful life and were in need of replacement.

Both the Fire Station 1 and Police Department generators were installed in 1999 (23 years old). Commercial generators have an effective useful life of approximately 20 years. While we do not currently have any known issues with these generators, their age increases the possibility that an issue could occur resulting in a serious disruption in public safety operations.

Due to the complexity and importance of having reliable generators for these public safety facilities, General Services is requesting approval of a Professional Services Agreement with McKinstry Essention, LLC for Phase I and II Generator Assessment and Replacement Design. McKinstry Essention, LLC has been providing professional services to the Town for Phase I and Phase II of the bond projects currently underway. As this is a professional service contract, a formal bid is not required.

PHASE I SCOPE OF WORK FOR POWER SYSTEM ANALYSIS SERVICES

McKinstry will perform an evaluation of the generator units located at Fire Station 1 and the Police Department. The scope includes, but not limited, to gathering data onsite, evaluation of utility electrical data provided to McKinstry from the Town of Addison for each site, reviewing data and feedback from facility personnel, and providing a report to list site by site, the current generation capability versus current facility estimated load, and the required generation capability to accept full facility estimated load.

PHASE II SCOPE OF WORK FOR PLANNING, SCOPING AND DESIGN

Scoping for design/build delivery including but not limited to:
- Recommendations for implementation and priority order of the installation of the new generators.
- Recommendation of controls to ensure reasonable future-proofing to allow for trending, monitoring and future load shed.
- Recommendation for generator commissioning plan to ensure new installations are producing quality electricity at all operation loads.
Design phase to include Full design of the generator installation electrical package. This includes, but not limited to the following:
- Develop electrical one line of electrical system from generator and utility down to first distribution transformer to provide insight to current system design and layout of each facility's electrical system.
- Arc Flash Analysis of each facility (if required).
- Gas piping and pressure analysis to determine if current infrastructure is capable of supporting the new generator load. If needed, design of new gas line to ensure proper loading.
- Creation of the permit set for bidding and permitting purposes.
Planning phase to include:
- Full detailed project schedule including critical path items and identification of major shutdowns and utility interruptions.
- Identify long lead time items and line up those for immediate procurement once the Town approves.

Upon approval of final deliverables from Phases I and II, the Town of Addison will start Phases III and IV; which include developing a Request for Proposal (RFP) for procurement, installation, and project management.

This item was approved by Council in the Fiscal Year 2023 Budget.

RECOMMENDATION:

Administration recommends approval.
