Report
Summary
On Feb. 18, 2020, the City and Project Engineering Consultants, Ltd. entered into the Large Diameter Sanitary Sewer Rehabilitation - Grade 5 Pipe Engineering Services agreement. The City received notification on Dec. 3, 2022, from Project Engineering Consultants, Ltd. indicating the name changed from Project Engineering Consultants, Ltd. to Consor North America, Inc. and is now operating under the name of Consor North America, Inc.
The purpose of this project is to rehabilitate the Large Diameter Sanitary Sewer System, which includes approximately 220 miles of pipe with diameter sizes greater than 15 inches and over 1,900 sanitary sewer manholes. The 2019 Large Diameter Sanitary Sewer Condition Assessment Report recommended rehabilitation of 55 pipe segments with Grade 5 Structural Rating. Grade 5 pipe segments contain severe defects that are the highest priority to rehabilitate.
This amendment is necessary as the project was phased into four design packages versus a single package, and the project deliverable was changed to manhole rehabilitation work sheet versus typical design sheet. This change increased overall project duration and review periods. This amendment will provide additional time to the agreement.
Project Engineering Consultants, Ltd.'s additional services include, but are not limited to: administer the construction schedule, review of submittals, issue interpretations and clarifications, certify contractor progress payments, inspections, survey, material testing, record drawings and project documents, and field administration.
Contract Term
The term of the agreement amendment is five years from the issuance of the Notice to Proceed. Work scope identified and incorporated into the agreement prior to the end of the term may be agreed to by the parties, and work may extend past the termination of the agreement. No additional changes may be executed after the end of the term.
Financial Impact
The initial agreement for Engineering Services was approved for an amount not to exceed $1.55 million. This amendment will increase the agreement by an additional $1.5 million, for a new total amount not to exceed $3.05 million, including all subconsultant and reimbursable costs.
Concurrence/Previous Council Action
