Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to modify and increase an engineering services agreement with CT Consultants, Inc., for professional engineering services for the Terrace/Broad Stormwater System Improvements Project. This project involves creating stormwater flood routing and eliminating structural and roadway flooding issues along West Broad Street near the intersection of Eldon Avenue.
Work performed to date includes analysis of the existing stormwater system within the project area as well as preliminary alignment layout and plan preparation. This includes several other smaller areas within the project limits that were previously undocumented flooding issues that were included after field investigations were conducted.
As part of the modification, several deteriorated water mains will also be replaced along Steele Avenue and Eureka Avenue which will increase the level of service to the local residents and reduce the likelihood of water main failures. The stormwater design and assessment work will be funded by the Division of Sewerage and Drainage (DOSD) while the water main replacement portion will be funded by the Division of Water (DOW).
1.1 Amount of additional funds for Modification 1 to be expended: $278,123.40
Original Contract Amount Ord. 0809-2011 $226,726.00 (EL010957)
Modification #1- Current $278,123.40
Total (Original + Modification #1) $504,849.40
1.2. Reasons additional goods/services could not be foreseen:
Upon completing the initial stormwater analysis it became apparent that a much larger system is required than originally anticipated. The entire roadway would have to be rebuilt (sidewalk to sidewalk) and all subsurface utilities would have to be relocated to accommodate the larger pipe at DOSD’s cost. The estimated construction cost for the work on Eldon Avenue was $2.9 million, not including work along West Broad Street.
In order to significantly reduce constructi...
