SUBJECT: City Hall Roof Replacement, Program No. 7911

Recommendations1. Approve the plans and specifications for the City Hall Roof Replacement, Program No. 7911;2. Approve the attached Resolution Authorizing the City Manager to Execute a Contract with

Garland/DBS, Inc., through the U.S. Communities cooperative purchasing system at a not-to-exceed price of $350,384 with an allocation of up to ten percent (10%) of the contract amountallocated for contingency purposes

Fiscal ImpactStaff has received a “not to exceed” cost from Garland / DBS, Inc. to perform the work necessary torepair the roof at City Hall in the amount of $350,384. If Council approves recommendations in this staffreport, Garland / DBS, Inc., will complete the project for this amount, or less, unless there are substantialchanges to the work, or unknown conditions.

This project is fully funded by Facility Replacement Funds in Program 7911.

Council Goal(s)This project addresses Council goals involving maintaining and improving our current infrastructure tomeet community needs now and into the future.

Background and AnalysisCity Hall Roof needs to be replaced.

The roof at City Hall has surpassed its useful life. Specifically, the underlayment beneath the clay tileshas deteriorated and the roof has been leaking significantly during the past few winters. Due to the natureof the roof composition and the deteriorated condition of the current underlayment, leaks are difficult andimpractical to repair. As a result, Facilities staff has most recently placed catch buckets in the attic tominimize water intrusion to office spaces below.

This project will replace the protective underlayment beneath the tiles as well as repair all dry rot anddamaged wood framing. The project also includes installation of a new gutter and downspout system andrepairing some of the mortar on selected exterior walls.

In order to maintain the historic character of the building, the Contractor will remove the original claytiles and store them onsite while the underlayment is replaced and all other work is performed. Then thetiles will be re-installed, and broken or cracked ones will be replaced with new. The original tilemanufacturer is still in existence so the match of the new tiles should be consistent, notwithstanding thedifference in the age of the tiles.

06-11-13 City Council Meeting 04B - 1

The City planned to solicit bids for the work using its usual procedure, and retained Indigo Architects toprepare technical specifications for the repair work. Indigo Architects provided complete technicalspecifications in 2012.

The City can contract for roof repairs through U.S. Communities.

Earlier this year, City staff learned that U.S. Communities, a nation-wide government purchasingcooperative, offered a contract for roofing materials and installation. Government Code Section 6500authorizes California public agencies to procure goods and services through a contract competitively bidby another public agency, including an out-of-state agency. This practice, sometimes called “piggybacking,” can be an efficient way to obtain necessary goods and services, as it generally requires less stafftime and upfront costs than traditional competitive bidding processes. It satisfies the statutoryrequirement for competition in procuring local agency goods and services. The City executed a MasterIntergovernmental Cooperative Purchasing Agreement with U.S. Communities in 2001, which remains ineffect.

The Garland/DBS proposal is advantageous to the City.

Garland/DBS, Inc. provides roofing materials and installation through U.S. Communities and is a licensedCalifornia contractor. Garland/DBS has given the City a “not to exceed” price for the repair work basedon the City’s technical specifications and observations at the site. Garland offers very favorable warrantyterms: ten years for the sloped portion of the roof, and thirty for the flat roof area. Garland’s warrantycovers the entire roof assembly; most roofing projects have no more than a one year warranty againstleaks, although individual parts of the roofing system may have longer warranties. Garland can providethese terms because it manufactures many of the roofing materials and takes responsibility for installingthe roof. Garland also provides periodic inspection of the roof materials during and after installation.

The procedure for entering into the construction contract through the cooperative system, if Councilapproves, will be as follows:

Garland will solicit at least three bids for installing the roof. The not-to-exceed-price will beadjusted if the installation bids are less than Garland estimated.The City will then execute a lump sum contract with Garland for the roofing project on the City’sstandard contract terms.

Recommendation 3, if approved, would allow the City Manager to award the project throughU.S. Communities government purchasing cooperative to Garland / DBS, Inc.

This process is expeditious in comparison to our traditional process, will allow us to complete the projectprior to the next rainy season and places less burden on City resources. The City will benefit from theinvolvement of the roof manufacturer in the installation and inspection of the roof, which should providea better quality installation and service. Many cities in California have used U.S. Communities for reasonssuch as these.

Staff has explained this process to the City Attorney, who has found the process acceptable.
