S CITY OF OSHKOSH WATER FILTRATION PLAN' MODIFICATIONS AND DEMOLITION PROJECT Reprised Professional Engineering Services In addition to the original Design Scope of Services and subsequent Contract Amendments, CH2M HILL, in collaboration with AECOM and Kaempfer & Associates, Inc., will provide to the City additional assistance with inspection, construction management and engineering through project completion December 31, 2009. The primary reason for this contract amendment are as follows; o Expanded Resident Project Representative Services + Additional Engineering Related to Unforeseen Site Conditions • Extended Duration of Construction Contract Schedule Expanded Resident Project Representative Services In response to the needs of the construction team, C 21M HILL increased the level of on -site construction inspection to ensure quality control and assist the Contractor meet the intent of the Contract Documents, The level of effort for Resident Project Representative (RPR) services was increased from approximately Ih -time to full -time. This additional effort has resulted more comprehensive quality assurance monitoring and improved: communication between the Contractor and the City. Additional Engineering Related to Unforeseen Site Conditions For over 120 years, the City has operated water supply, treatment and storage facilities at the current Wafter Filtration Plant. Over the years, some buried piping, small facilities, other utilities, and unsuitable soils have been abandoned in place. The City maintains eery good documentation of historic changes at the site, but the documentation, especially the oldest information, is not 100- percent accurate or complete. As a result, unplanned situations, occur during construction and additional engineering services are required to solve problems and minimize the impact to the construction schedule_ For example, Engineered solutions were needed to address undocumented site conditions (leaking buried piping and valves, abandoned buried features (i.e., old well), or unsuitable soils). Design changes were required to adjust for incorrectly located buried utilities, as shown on existing record drawings, so that connections could be made in this project. • Design changes resulted in changes orders that required scoping, detailed review and negotiation with the Contractor by engineering and RPR staff. Extended Duration of Construction Contract Due primarily to unforeseen site conditions, the Construction Contract Times has been extended 90 days by change order. Consequently, the construction activities originally 2 ATTACHMENT 1- SCOPE OF SERVICES AMENDMENT NO.5 CITY OF OSHKOSH WATER FILTRATION PLANT MODIFICATIONS AND DEMOLITION PROJECT scheduled for completion July 30, 2009 have a contract completion date of October 30, 2009. In addition to this agreed extension to the Contract Times, the Contractor has proposed in 2009 schedule updates that the Contractor's anticipated construction completion is late November 2009. Given this available information, we recommend the City on needing engineering assistance through December 2409 for project closeout activities.
