Approval of a Consultant Agreement with OTAK, in the Amount of $207,958, for the Connection to King County Wastewater System - Avondale Way
OVERVIEW STATEMENT:
recommendation
Public Works is requesting approval of a consultant agreement with OTAK in the amount of $207,958. This agreement is for design services for the Connection to King County Wastewater System - Avondale Way, which will replace 20 lineal feet of existing 18” reinforced concrete pipe with 27” reinforced concrete pipe. The work will include a new saddle manhole at the connection point with the King County Trunk, and abandonment of the existing connection.
Three consultants were selected from the MRSC roster for Engineering Services to submit proposals. Two proposals were received, and OTAK’s proposal was rated the highest. Scope and budget were then developed with OTAK to move forward.
