Condition Evaluation of Force Main Sample Clauses

Condition Evaluation of Force Main. Conduct non-destructive FM condition assessment to include the following. ▪ Visual inspection of the pipeline suspended on the bridge, where it is accessible. ▪ Confirm air valve condition by visual inspection and confirm operation of valve. ▪ Collect ultrasonic thickness readings to determine remaining pipe wall thickness at inspection location. ▪ Perform head and flow testing to estimate internal roughness of force main system. ▪ Inspect three-way plug valve that was installed in the early 2000s at the connection to the HDPE section of FM to determine if there is corrosion and if it is a potential failure point. A summary of the condition evaluation performed, and recommendations for additional evaluations or pipe replacement will be included in the preliminary design report, as applicable. If the condition evaluation determines that there are significant concerns about the condition of the force main pipe located on the bridge and more intrusive destructive-type evaluations are recommended, that additional work will be negotiated with the City under a separate scope of work. Task Deliverables ▪ Kickoff meeting minutes ▪ Topographic survey map and CAD file ▪ Condition evaluation forms ▪ Draft and final Geotechnical Data Report and Engineering Report Assumptions ▪ Kick-off meeting to be held remotely using a virtual meeting format acceptable to the City. ▪ City to provide applicable pump station documents and information to Consultant within three (3) days of Consultants information request. ▪ Lift station condition evaluations will be completed by up to five (5) members of the Consultant team. City will provide calibrated pressure gauges at the pump station to conduct flow and head testing. ▪ Force main condition evaluations will be completed by up to three (3) members of the Consultant team. City will locate and expose plug valve. ▪ Structural evaluation will be limited to visual observation and review of as-built documentation. No destructive investigation will be performed. If additional investigations or mitigation of seismic deficiencies are required they will be negotiated with the City under a separate scope of work. ▪ Geotechnical subsurface explorations assumptions: o All necessary right-of-entry permits will be provided by the City. o The subsurface material is not contaminated, and no testing will be performed to investigate the possible presence of toxic or hazardous materials and petroleum products. o No permits will be required, including p...
