Agenda Title:

Council action is requested to issue a purchase order to HDR Engineering, Inc., in the amount of  $417,180.00 for an architectural and engineering services biosolids improvements plan for the Water Pollution Control Department. 

Council action to issue a purchase order.


Due to changes in federal air emissions regulations, the incinerator at the Rock Creek Wastewater Treatment Plant (WWTP) was taken out of service in March 2016.  Since that time, the biosolids produced from the treatment processes at the Plant have been disposed of in the Courtney Ridge Landfill.  As this is not a sustainable solution, a Solids Facility Plan was completed for the City by HDR Engineering, Inc.  This Plan recommended the construction and implementation of lime stabilization facilities and the disposal of the biosolids through land application. It is recommended to proceed with design services for a Class A biosolids process.

The design portion of the project will be funded by the capital project for Sewage Sludge/Incinerator Improvements (Project #70301505), which was approved by Council several years ago. This project has an available balance of $997,557.78.

The proposed contract with HDR Engineering, Inc. will provide project design services and construction management, at an amount not to exceed $417,180.  This cost was included in the total project cost estimate of $5.1M.

HDR Engineering was selected per State Statute 8.285, et seq, which calls for seeking architectural, engineering and land surveyor services based on qualifications.  The Procurement Division issued a Request for Qualifications annually and has established a qualified list for such services.


Approval of this item authorizes the Procurement Manager to issue change orders up to a total of ten (10) percent of the original authorized amount for each order, providing appropriations are available.
