Explanation

BACKGROUND: This Ordinance authorizes the Director of Public Utilities to modify and increase the professional engineering services contract with Malcolm Pirnie, Inc. for the Dublin Road Water Plant Chlorine Storage Improvements Project. The original contract provided for engineering design; Modification No. 1 provided for construction administration services for a separate chlorine storage feed system and Modification No. 2 provided for additional engineering design for a new disinfection chemical to be utilized at the Dublin Road Water Plant. This contract modification will provide for additional design services, construction services, and regulatory compliance services. Added complexities have been of significant impact to the amount of construction services required. Extended contract duration caused increased hours for engineering services during construction. Difficulties with contractor work including the temporary chlorine scrubber and the sodium hypochlorite tanks caused project delays and increased engineering evaluation and testing services. More extensive rehabilitation work in Sedimentation Basins than originally anticipated required additional engineering services during construction. The more extensive rehabilitation work in the basins was due in part to the delay between the initial design and the bidding and awarding of the project.
