Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to modify the professional engineering agreement with URS for Overbrook / Chatman Integrated Solutions Project. CIP#650870-100004. It is the objective of the City to mitigate overflows of DSR 335 to the 10-year level of service. The City will evaluate and determine if this LOS (level of service) is best achieved with strictly I&I elimination with GI or in combination with some gray infrastructure.
To accomplish this objective, the scope of work for this project will include all the requisite investigation, evaluation, formulation, and design to produce fully independent construction documents for the remediation of inflow and infiltration (I/I), green infrastructure (GI) technologies and other related activities and/or documents necessary for project completion.
However, due to the investigative nature of these pilot projects, additional funds are required in order to complete the requisite preliminary design elements before completing construction plans and specifications, therefore the need for this modification.
It is anticipated that another contract modification will be required in 2015 in order to provide funds to complete the tasks associated with bidding procurement, engineering services during construction, and record planning.
1.1 Amount of additional funds to be expended: $ 295,499.20
Original Contract Amount ($): $ 1,212,876.00
Modification #1: $ 295,499.20
Modification #2: $ 280,000.00
Total $1,788,375.29
1.2. Reasons additional goods/services could not be foreseen:
This was an anticipated modification. It is a planned continuation of the services originally included within the existing contract’s scope of service.
1.3. Reason other procurement processes are not used:
Re-bid of the project under the new requirements will likely result in a higher project costs as much of the project history would be lost and required to be...
