Amend 1 to PSA with HDR Eng for Davis Lane Lift Station and Norton Sewer Commission Memorandum REPORT TO: Honorable Mayor and City Commission FROM: Bob Murray, Project Engineer Shawn Kohtz, City Engineer SUBJECT: Davis Lane Lift Station and Norton Sewer Project - Amendment No. 1. MEETING DATE: September 9th, 2019 AGENDA ITEM TYPE: Consent RECOMMENDATION: Approve and authorize City Manager to sign Amendment No. 1 with HDR Engineering. BACKGROUND: Attached is a copy of the partially executed Amendment No. 1 with HDR Engineering for the Davis Lane Lift Station and Norton Sewer Project. The document is in the City’s standard format. During the course of the design completed to date, there have been a number of items that came up that were not included in the original scope. Additional geotech work and cathodic protection for the bore casing had to be added to satisfy the requirements of the MRL permit. Some additional wetland delineation needed to be completed after the alignment of the main was altered. Design of a water main crossing the interstate and railroad was added so it could be completed under the same permits as the sewer crossing, and an architectural design review application has been added to meet the city site plan requirements. This amendment covers the compensation for these additional items. UNRESOLVED ISSUES: None ALTERNATIVES: As suggested by the City Commission FISCAL EFFECTS: $39,834.00 from the Wastewater Impact Fee Fund.

(Terracon) appreciates the opportunity to submit this supplementalchange order to provide additional geotechnical engineering sen/ices for the project referencedabove. The purpose of the additional proposed engineering services is to complete two boringsthat could not be advanced during the initial mobilization and provide estimated fees for twoadditional borings proposed within the railroad right of way associated with the proposedhorizontal bore crossing.A. PROJECT INFORMATIONSite LocationITEMDESCRIPTIONLocationThe proposed lift station is located east of the intersection ofNelson Road & North Frontage Road in Bozeman, Montana. Theproject includes utility installation to the south and east of theproposed lift station.Latitude/Longitude N 45.725745°, W 111.078953° (approximate)Existing ConditionsInterstate 90 and existing railroad tracks are located to the south ofthe proposed lift station.

ADDITIONAL SERVICESDuring the initial mobilization, two proposed borings, B-5 and B-6, were unable to be performed.The location of B-5 had not yet been confirmed and the soil conditions encountered at B-6 weretoo wet and soft to access with the drill rig. After a brief discussion with Mr. Jeff Heidner withSanderson Stewart, he indicated that both borings could be drilled at a later date when the locationof B-5 was finalized. We discussed with him an additional mobilization would be required toproceed.A second mobilization was made the week of June 17, 2019 to attempt to drill boring B-6 (boringB-5, B-7 and B-8 had not yet been authorized by MDT). During the mobilization, the drill rig couldnot access the location of boring B-6 as the boring location was surrounded by a raised earthenberm the rig could not navigate.A third mobilization was made the week of July 15, 2019 to complete the remaining borings (B-5through B-8). The cost for two (2)additional borings (within the railroad right-of-way) beyond thoseoriginally proposed is also being requested as a separate line item. Two additional borings locatedwithin the MRL right-of-way, advanced to a depth of approximately 25 feet or practical augerrefusal, additional laboratory testing, MRL permitting requirements, and reporting time areincluded in the breakdown of the additional two railroad borings. As requested by SandersonStewart, COP Construction made a site visit with a CAT 335F excavator to excavate an entry pathto boring B-6 for the drill rig and excavate test pits near borings B-5, B-6, and B-8 so we couldobserve and document cobble and/or boulder sizes within the gravel stratum. One day of trafficcontrol, provided by Mountain West, has also been included for the work along MontanaDepartment of Transportation right-of-way.C. COMPENSATIONBased on information outlined above, we propose to complete the work on a time and materialsbasis under the current project contract terms between HDR, Inc and Terracon. An estimate ofadditional fees requested is provided below. The below estimate anticipates all borings can bedrilled out of traffic and as such, the fees below do not include time associated with traffic control.The below costs also do not include any costs associated with acquiring permits to perform workwithin the railroad or City right-of-way.Item 1 - Additional mobilization to complete boring B-6 (June 17)EstimatedFeeMobilization for Terracon and Drill subcontractor to drill boring B-6.
