CC: Kent Power,P.E., Jerry Shoemaker,P.E.;Anne Hoskins,P.E. FROM: Richard Provolt,CCM SUBJECT: Change Order No.5-Pipeline DATE: February 16,2016 PROJECT: Mary Rhodes Phase 2 Pipeline Project—Pipeline Contract Mr. Edmonds, This memo serves as a summary for the reasons and recommendation for the items in Change order No. 5 for the pipeline contract. Item No 1.—CP 20/RCP 03 Pipeline grade adjustment at RR berm at station 1037+60 This Request for Proposal to the contractor was generated from an Owners request to change the profile of the pipeline in this location.The change made the pipeline grade line flatter and took out a hill that would be challenging to work around if maintenance procedures needed to be done in this location.Two additional days of Contract time are recommended for this work. Item No 2.—CP 04 Conflict-Enterprise Pipeline affecting Tunneling Sub at station 1132+65 This claim from the contractor was to compensate for the delays and additional work associated with an Enterprise gas line that was 2.5 foot deeper than indicated in the Contract Documents.This required the contractor to excavate deeper, lower the location of the pipeline casing and use additional materials to compensate for the extremely wet soils in this area.The onsite CM team monitored the situation closely and documented the work described in this change package. Four additional days of Contract time are recommended for this work. Item No 3.—CP 07 FOC Conflict @3131/CR423 This claim from the contractor was to compensate for the delays associated with the discovery of buried fiber optic cable and telephone lines that were not indicated in the Contract Documents.The contractor was able to reinstall the pipeline at a slightly different grade and avoid production of any further piping or relocation of the existing utilities. One additional day of Contract time is recommended for this work. Item No 4.—CP 08 Field location verification of new FOC utilizing Vac Truck at station 1735+25 This claim from the contractor was to compensate for the delays associated with locating a fiber optic cable that was installed after this contract was let. The contractor utilized a vacuum truck to locate this new utility.The work took close to a week to perform however equipment and manpower were able to be utilized in other areas of the project minimizing the impact of the delay claim.The onsite CM team monitored the situation closely and documented the work described in this change package. Four additional days of Contract time are recommended for this work. Memo February 10,2016 Page 2 of 2 Item No 5.—CP 10/RCP 08 Move power from MOV3001 to MOV3003(Existing Emergency Breaker) This Request for Proposal to the contractor was generated from LNRA's request to change the power supply connection location for two new motor operated valves so they would be connected to an existing backup emergency generator. No additional days of Contract time are recommended for this work. Item No 6.—CP 11 Bollard modifications at rectifiers This claim from the contractor was to compensate for the additional work associated with revising fabrication of the protective bollard system protecting the cathodic protection system rectifier cabinets.The specified cabinet doors would not be able to open fully for maintenance with the standard bollard system hence the modifications. No additional days of Contract time are recommended for this work. Item No 7.—CP 18 Photocells for GST lighting This claim from the contractor was to compensate for the additional work associated with adding photocells at the existing pole mounted LED lights at the new ground storage tank.This change will allow the pole mounted lights to operate in sync with the photocells on the electrical control structure. No additional days of Contract time are recommended for this work. Item No 8.—CP 19 Additional AEP easement surveys for underground electrical This claim from the contractor was to compensate for the additional work associated with obtaining surveys for new easements that AEP required to run underground electrical supply for 9 of the 18 cathodic protection system rectifiers. No additional days of Contract time are recommended for this work. Item No 9.—CP 21 Unsuitable soils at eastside of Navidad River bottom This claim from the contractor was to compensate for the additional work associated with installation of pipe above unsuitable soils. In the river bottom on the east side of the Navidad River the contractor encountered highly plastic,wet and unstable soils in the bedding area of the pipeline profile.The unstable soils needed a bedding layer that would stabilize the subgrade for sound pipe installation. Bull rock and 1.5"gravel were brought in and utilized to establish a solid bed for the pipe sections.The contractor had to outsource these materials which accounts for a significant part of the cost in this change.The onsite CM team monitored the situation closely and documented the work described in this change package.Four additional days of Contract time are recommended for this work. Item No 10.—Additional days added to Contract-15 Calendar Days Embedded within the nine items listed above, FNI recommends the addition of 15 additional days to the overall Contract time. Based on negotiations between the PCM and the Contractor FNI recommends approving these changes.The pricing is considered fair and reasonable as well as the requested contract time for each item. �r% FREESE ` ' al.MICHOLS .of. . 2.,:1.,'.P,.,-,,#),.4.'
