TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
VIA: SERGIO GONZALEZ, CITY MANAGER
FROM: DANIEL BOBADILLA, P.E., DIRECTOR OF PUBLIC WORKS/CITY ENGINEER
DATE: APRIL 2, 2018
SUBJECT: AUTHORIZATION TO SOLICIT BIDS FOR THE WEST WING CEILING
ABATEMENT PROJECT
SUMMARY:
An air quality test and material survey were conducted in the City Hall West Wing building. Test results
recommend thorough cleaning above the drop ceilings and replacement of insulation and ceiling tiles
throughout the entire West Wing. The proposed action will authorize Staff to solicit bids from qualified
contractors to rehabilitate the ceiling at City Hall West Wing.
RECOMMENDATION:
Staff recommends the City Council take the following actions:
1) Approve the project plans; and
2) Authorize Staff to solicit a Notice of Inviting Bids for the West Wing Ceiling Abatement Project
DISCUSSION:
On September 8, 2015, Aurora Industry Hygiene, Inc. performed an air quality test and visual inspection
of the spaces above the drop ceiling system in the West Wing of City Hall. The test results
recommended removal and replacement of the drop ceiling system and insulation. Prior to proceeding
with these improvements, Staff obtained the services of Owen Group and Ninyo & Moore to conduct a
thorough analysis of all the materials in the ceiling system. The material survey, conducted on August
24, 2017, affirms the removal and replacement of the existing drop ceiling system and fiberglass
insulation and also recommends the abatement of various materials within the ceiling system.
If approved by the City Council, Staff will solicit bids from qualified contractors. Staff will review
submitted bids and request approval from the City Council to award a contract at a future meeting.
