Executive Summary:

Sonoma Valley County Sanitation District (District) treatment plant has three buildings identified to have roofs in need of replacement.  This project will design roof replacements on the administration, maintenance shop, and influent/effluent buildings (Project).  Due to the unique demands placed on buildings at a wastewater treatment facility, the services of an engineering firm is desired to design the roof replacements.




There are three District treatment plant buildings that have roofs with leaks.  They are the administration, maintenance shop, and influent/effluent buildings which all have the original roofs from when they were constructed in 1977.  The Project consists of designing the replacements for aging roofs and related appurtenances.


The type of roofs necessary at a wastewater treatment plant differ from typical commercial roofs.  They require unique design adaptations to achieve the required temperature parameters for operations equipment and laboratory instruments, and to accommodate specialized ventilation systems for the equipment.  The District does not have staff with this expertise, therefore, an engineering firm is needed to design the roof structures and to determine the exact roofing system materials demanded by the site. 



On May 17, 2019, Sonoma County Water Agency (Sonoma Water) issued a Request for Statements of Qualifications (RFQ) to the 36 engineering firms listed in Attachment 2 (Recipient List).  The RFQ was also posted on the Sonoma Water and County of Sonoma Purchasing Department websites.


The 22 firms listed in Attachment 3 (Statements of Qualifications Received) submitted Statements of Qualifications (SOQs)


The following criteria were used to evaluate each firm:

1.                     Thoroughness of SOQ.

2.                     Professional qualifications and demonstrated ability to perform the work.

3.                     Exceptions to standard terms in the sample agreement).


Based on the evaluations, all 22 respondents were determined qualified and included on the list of qualified consultants.


Allana Buick & Bers, Inc. (Consultant) was selected for this project because they have specific experience designing roofs for wastewater treatment plants.


District may seek to amend or enter into subsequent agreement(s) with Board approval if required, relying upon this competitive selection process, after the preliminary or initial work is completed for the Project.



Under the proposed agreement, Consultant will prepare Project design drawings and specifications, and provide support to District during bidding and construction.


The cost of services will not exceed $245,000; the term end date is September 15, 2023.


The agreement includes two options for District to extend this agreement for a period of one year each by providing written notice to Consultant thirty days in advance of the expiration date of the agreement and of the first extension option.


Until this project is completed, Sonoma Water staff will continue to capture and divert rainwater as it enters the buildings in order to protect vital equipment.
