Explanation
1. BACKGROUND:
This legislation authorizes the Director of Public Utilities to modify the professional engineering services agreement with EMH&T, Inc., in connection with the Blacklick Creek Sanitary Interceptor Sewer, Part 6C Project. The consultant has performed the requisite field surveys, geotechnical investigations, and hydraulic calculations necessary to generate the Preliminary Engineering Report which outlined the recommended horizontal and vertical alignments for the proposed sewer. The report concluded that the most economical method for constructing the sewer will be via tunneling methods.
In the future the consultant will perform all necessary geotechnical investigations, field surveys, obtain and prepare all permits necessary, generate detailed construction plans and specifications, prepare site-specific maintenance of traffic plans, and supply all construction documents required for bidding. There is at least one future modification planned. The updated contract timeline is January 2015.

Reason other procurement processes are not used:
Given the highly technical nature of the project and the specialized knowledge of the project area required to complete the services, it would be more costly to solicit proposals for completion of the services by other partie...
