	CONTROL SYSTEMS

	Mount Hope Water Main Project Panama The General Contractor engaged Nielsen-Wurster to review a number of claims submitted by its subsidiary company on the Mount Hope Port Water Main Project in Panama. The Project involved placement of approximately 12,000 linear feet of ductile iron water main within a 300-day period. A number of impacts were introduced during the course of the Project by the Panama Canal Commission, in addition to differing site conditions and severe weather conditions that delayed the Project substantially from its scheduled completion date. Nielsen-Wurster reviewed six claims submitted by Contract Plumbers that had been subsequently denied by the Panama Canal Commission. It was Nielsen-Wurster's opinion that three of the six claims were valid for additional direct and overhead expenditures by Contract Plumbers and were beyond the contractual requirements of the Project. Nielsen-Wurster prepared a report of its findings that was presented to the Panama Canal Commission and enabled all issues to be resolved favorable to the Client.

	Nespelem Domestic Water System Improvement Project Nespelem, Washington, USA Nielsen-Wurster was engaged by the engineer of record to evaluate the adequacy of design standards employed by the design engineer on the $1 million Nespelem Domestic Water System Improvement Project. Nielsen-Wurster reviewed the design for the water system and provided deposition testimony on the standard of care exhibited by the design engineer. The case was settled following depositions of Nielsen-Wurster personnel.

	Pawling Wastewater Treatment Project Pawling, New York, USA Nielsen-Wurster provided claims management services for a wastewater treatment plant under construction in Pawling, New York. Nielsen-Wurster reviewed and evaluated change orders submitted by the General, Mechanical and Electrical Contractors and to made recommendations to the Town of Pawling and the New York Department of Environmental Protection regarding approval of such change orders. The total cost of the change orders reviewed by Nielsen-Wurster was approximately $1.9 million. Nielsen-Wurster provided an analysis of project documentation and excess costs through extensive review of the submitted change orders, meetings with Project personnel and interface with legal staff. Finally, Nielsen-Wurster recommended that $625,000 in change orders be disallowed; thereby providing the Town's attorney a basis for negotiation.

	Pinellas County Water System Pipeline Pinellas County, Florida, USA Nielsen-Wurster evaluated professional responsibility for construction phase services related to a claim submitted by Pinellas County against CH2M Hill on a water pipeline project. The Pinellas County Water System contracted with CH2M Hill for the design of approximately 12.5 miles of a 54-inch and 60-inch pre-stressed concrete and steel cylinder pipe water pressure main as part of the County's main distribution system. The County solicited bids and awarded contracts for the manufacture and installation of the pipe using CH2M Hill plans and specifications. The County also placed its own crew of inspectors on the Project. Approximately one year after completion, one segment of pipe failed and, subsequently, a second segment failed under hydrostatic testing. The County filed a claim against CH2M Hill for failure to perform its professional responsibilities during the construction phase of the contract. Nielsen-Wurster evaluated the contract documents and national standards of specification for design, manufacturing and installation of pressurized concrete pipe. Based on the results of the evaluation, Nielsen-Wurster provided testimony supporting CH2M Hill's design and construction phase services.

	Bergen Point Wastewater Treatment Plant Babylon, New York, USA Suffolk County engaged Nielsen-Wurster to analyze claims for the 400 MGD sewerage treatment plant in Babylon, New York. The General Contractor sought in excess of $20 million in damages for alleged Owner and Architect/Engineer contract breaches, delays and disruptions. The Owner sought return of the full $60 million-plus contract price, alleging deficient Contractor workmanship, delay and contract breaches. Nielsen-Wurster developed detailed delay analyses using its Window Analysis* technique to identify, quantify and assign responsibility for Project delay by utilizing the contemporaneous project schedules and analyzing the delays which occurred between each of the issued schedules. Additionally, Nielsen-Wurster evaluated actual and alleged workmanship issues, design issues, inspection adequacy issues, then developed detailed damages quantification support. Through Nielsen-Wurster's analysis, Suffolk County was able to receive a favorable settlement on the case.

	Bowery Bay Wastewater Treatment Plant Queens, New York, USA Nielsen-Wurster analyzed construction disputes for the City of New York on the Bowery Bay Wastewater Treatment Plant built in the l970s. The Project involved upgrading and expanding certain existing facilities to meet the current EPA requirements for discharge and was funded substantially by EPA and the New York State Department of Environmental Control (DEC). At the conclusion of the Project, the Prime Contractors filed claims against the City of New York totaling about $36 million against a total contract value of $75 million. The Contractors' claims included issues of changed and unanticipated subsurface conditions impacting excavation, pile driving and foundation work; defective design by the Architect/Engineer; and lack of proper coordination among the Prime Contractors. Nielsen-Wurster analyzed the schedule impact and the responsibility for the impact(s). The analysis also required a comparison of various schedules developed for the Project and during the Project such as the bid schedule, contractors proposed schedule and ongoing revisions to the schedule to meet the EPA's imposed timetable for meeting the requirements of discharges to the river. The case was settled.

	Hamilton Wastewater Treatment Plant Hamilton, New York, USA Nielsen-Wurster analyzed the delay claims pursued by the General Contractor hired by the Village of Hamilton to construct modifications to the existing wastewater treatment plant. The Contractor filed a Demand for Arbitration against the Village of Hamilton claiming a total of 114 days of delay and 6 months delay damages plus interest, costs and legal fees. Nielsen-Wurster reviewed the entire Project for total delay and responsibility and also reviewed the validity of the Contractor's claims. Nielsen-Wurster reviewed all the available Project technical and non-technical documentation and subjected those documents to expert analysis. Using Project schedules developed by the Contractor, with input from other prime contractors, Nielsen-Wurster compared scheduled progress against actual progress according to the engineer's daily reports and chronologies developed through the document review. Nielsen-Wurster then employed its expertise in the area of construction engineering and construction management to analyze the claims set forth. Based upon Nielsen-Wurster's report, the Village of Hamilton was able to reach a favorable settlement to the claim.
