AGENDA CAPTION:

Consider Action on a Resolution Approving Change Order #1 to the Contract Between the Town of Addison and TDIndustries, Inc. for Additional Electrical Work at the Police and Municipal Courts Upgrade Project and Increasing the Contract Amount by $123,114; and, Authorizing the City Manager to Execute the Change Order in an Amount Not to Exceed $779,774.51.

BACKGROUND:

On November 5, 2019, voters approved Proposition D which included $7,395,000 for facility improvements at existing municipal facilities including the replacement of Heating, Ventilation and Air Conditioning (HVAC) systems. Phase One included the replacement and upgrade of the Police gun range HVAC which will filter the air within this facility to provide a safe environment for users of the range. Staff, along with the Town's representative McKinstry, solicited bids through a Request for Proposal (RFP) process. TDIndustires was the low bidder with a final cost of $656,660.51 (including payment bond, performance bond, and maintenance bond).

Despite efforts to determine the anticipated electrical load during the design phase, it was later determined that the facility needed a larger transformer to accommodate the increased demand with the new HVAC units. The Town's consultant will be on-site at the meeting to answer any detailed questions.  When Oncor conducted a site visit they indicated that the current transformer location did not meet their current standards because it lacked the minimum 10’ clearance to allow Oncor staff to safely work on the transformer. To meet Oncor's requirements, the new transformer will be relocated across the parking lot (see attached diagram).

This change order is for TDIndustries to run all necessary wiring, conduit, provide a new pad, provide a pathway for the utility conductors from the pole drop, and connections from the new transformer location, across the parking lot and reconnect power to the facility. In addition, they will decommission the old transformer. Oncor will provide the new transformer and pole to provide the power. The $123,114 for this change is not included in the bond funds but will be included in an end of the year budget amendment from the Self Funded Special Projects Fund.

One Town tree will be trimmed to allow crane access to set the transformer. A shrub on an adjoining property that is located in Oncor's easement will be removed.

The careful observer will note that signatures normally provided in the proposed document are yet to be filled in. A last minute update necessitated making a new document which did not afford us the time to obtain the signatures prior to posting. These will be obtained prior to the Town executing the document.

RECOMMENDATION:

Administration recommends approval.
