The following information is included in this recommendation letter for your and the Commission's review: Summary of Scope Changes, and the General Construction Contract Summary. Summary of Scope Change: • Change Order Request No. 2 — FRP Wall Panel Improvements • Cost Increase: $25,620.00 • Contract Time: +14 Days • During the early construction phase,Western Municipal suggested and provided a quote for removing the existing drywall finish and replacing with insulated FRP paneling.The poor condition of the existing walls was noted during the design but value-engineered out of the Bidding Documents to save on project budget. The Contractor noted this work is best to complete while the process piping and existing electrical is "gutted" from the facility and wanted to give the City this option while the opportunity was present. AE2S and the City agreed with the contractor's approach and decided to move forward with the proposed improvements. The change order covers the following work: removal of the existing drywall panels, insulation, and framework; and installation of new wall framing, support header, rigid foam insulation, dry-wall, and FRP panels per construction the detail sketch provided in WCD No. 2. The improvement provides the following benefits: cleaner finished work environment, easier cleaning and maintenance with water resistant finishes, and sturdier support headers for hanging electrical panels. The estimated labor included in the PCO price was generally in line with the labor and time AE2S observed and recorded on-site, and the Contractor has provided the invoice for the materials estimated. Advanced Engineering and Environmental Services, Inc. 1288 North 14th Avenue,Unit 103 • Bozeman, MT 59715 • 406-219-2633 4t\; • Extension of Contract Time • Cost Change: $0.00 • Contract Time: +9 Days • A total of 9 calendar days are added as a result of the following change of conditions: i. Discrepancy between the record drawing, project drawings, and the field condition of the existing supply line located in the northwest corner of the building. ii. Alignment issues depicted on the existing pump discharge lines. iii. Orientation difficulties on the surge anticipation line due to existing bolt patterns. • The change of conditions listed above are legitimate changes AE2S observed on site. AE2S will reflect the changes in the record drawings as best as reasonably possible. • Modification in Process Piping: • Cost Decrease: ($581.12) • As mentioned in the extension of contract time section, WMC had to utilize an additional reducer in We of a new 12" valve. As a result of this field modification the new 12" valve was not installed.WMC offered a cost deduct for the difference in cost between the fitting and the valve. • Stop Work Order: • No Cost Change • WMC will shut down construction activities for the Christmas Holiday and requested a Stop Work Order to suspend contract days between December 23,2019 and January 5, 2020. During this time, no work will be performed in the field by either WMC or AE2S and the contract days will be suspended to allow Substantial Completion to be achieved after the holiday break.

MT Q oorr� December 11,2019 AE2S Attn:Brian Viall,PE 1288 North 14"Ave,Unit 103 Bozeman,MT 59715 406-579-5104 RE: PCO5—Request for Time Extension Due to Misc.Change of Conditions Pear Street Booster Station Project—Bozeman,MT I Mr.Viall: This Proposed Change Order(PCO)outlines miscellaneous field conditions differing from the conditions represented in the Project Drawings and Specifications for the Bozeman Pear Street Booster Station Rehabilitation Project and,resulting from these changes,requests an extension in Contract Time. For projects similar to the Pear Street Booster Station,we expect a certain level of changes to be identified in the field and hope the City will agree. Because Western Municipal Construction strives to build reputation with our Owners based upon positive relationships,we have not previously asked for any change in Contract Price—nor are we asking for any increase in Contract Price in this PCO.WMC proposes to absorb the additional cost of these changes in exchange for a reasonable extension in Contract Time. A brief summary of the changes significantly impacting our Construction Schedule is outlined below with an associated time extension WMC feels is reasonable. 1. 25 hp pump shipped with incorrect pump skid. a. All reasonable efforts were made to coordinate the details of the pump skid with the process piping based on reviews of the submittal drawings provided by the pump Supplier.However,upon arrival of the pump shipment,we identified a discrepancy in the shop drawings and the pump skid actually provided by the supplier. The discrepancy resulted in the alignment on the pump suction and discharge connections being more than 3 inches off from the alignment we had set our pump pad and process piping to match. Had the pump arrived with the proper skid,all of the other time delays could have been absorbed into the Contract Time's previously included in Change Orders and Work Change Directives to date,however given this change of conditions was only identified on December 3,2019,there was not sufficient time remaining on our contract to make 1 the adjustment. NC" i. Additional Contract Price Requested:$0.00 ,ii. Additional Contract Days Requested, 2. Pump Supplier Changed Ownership Between Design,Bidding,and Construction: a. Industrial Systems(IS)was the pump supplier for the Pear Street Booster Station.WMC understands IS was one of the suppliers AE2S worked most directly with during design. In the Summer of 2019,IS changed Ownership. Given so Hutch administrative turn-over, WMC put in extra time to work with the new business owners to coordinate the approval, manufacture,shipment,and delivery of these pumps. Though we acknowledge this change of conditions is a natural part of construction supply chains and is completely out of AE2S' or the City's control,we also feel this change is out of WMC's control and respectfully request a time extension to cover the time this change in supplier ownership caused on the project. Most directly,it was the shipment and delivery schedule provided from the pump supplier that influenced WMC's decision to start construction on September 23 rather than September 15(the day the Contract would have allowed us to start). b. Additional Contract Fee Requested: $0.00 n„ _ � /A),* c. Additional Contract Days Requested + ^'�'r�ct 3. Existing Process Pipe Alignments Differ from Project Drawing The existing process piping was"fixed"by the concrete floor penetrations and presented the following complications during the course of construction: a. Supply line in NW corner was represented as 10"in record drawings and in the Project Drawings. That line is actually 12"and required an additional reducer to replace where a new 12"valve was scheduled to be installed.This one change then matriculated down the distribution manifold and the bypass line because of the fitting dimensions. WMC will offer a Cost Deduct for the difference in cost between the Fitting and the Valve. i. Credit for Contract Fee:-$581.12 ii. Additional Contract Days Requested:3 Days b. Pump discharge lines are represented as uniform and centered r a single line. Th pipes are in fact not in any single alignment,nor are they perfectly parallel to the suction header as the drawings would imply. This required numerous changes to process pipe layout and required custom sizing fittings and spools for field installation. i. Additional Contract Fee Requested: $0.00 ii. Additional Contract Days Requested:4 Days c. Pipe supports—WMC supplied and installed pipe supports ab and beyond the umber of pipe supports specifically identified in the project drawings. These were installed at WMC's option given our expertise in field installation and support of process pipe. Additionally,the revisions included in WCD No.2,had unforeseen impacts to the pipe supports along the back wall for the PRV on the suction side supply header. i. Additional Contract Fee Requested:$0.00 ii. Additional Contract Days Requested: 0 Days d. Surge Anticipation Line orientation—plans show a pair of 45 deg angles to get the surge line out of the building. Due to the orientation of the existing bolt pattern on the existing flange—fixed by the discharge pipe penetrating through the concrete floor-this could not be built as drawn with the 45 Degree fittings already purchased. Measurements had to be taken and new fittings(tea 22.5-deg, lea 9.3-deg flange wedge)were ordered at no additional cost to the owner. ^,, i. Additional Contract Fee Requested:$!4�4 00 ii. Additional Contract Days Requested: ays 4. Changed the Location of the Electrical Light Switch. a. We submitted an RF1 for the location of the main light switch in the building that was installed per plan by our electrician. After installation,we requested the location be reconsidered as it was drawn and installed in a less then optimal location for the City's use. AE2S approved the RFI and agreed it would be more convenient for the Owner to have the switch on the other side of the door. There was no cost associated with this change and we are not requesting any additional contract days at this time. i. Additional Contract Fee Requested:$0.00 ii. Additional Contract Days Requested:0 Days i 5. Addition of security bypass switch for door contact. a. 12/9/19 John Alston asked how the door contact would be shutoff when someone enters. This is not addressed on the plans and the door contact would be live at all times,thus resulting in constant alarms and the City Shop. On 12/10/19 we had our electrician install an operational bypass switch for the door contact.There was no cost to the City associated with this change and WMC will waive any additional time this work required. i. Additional Contract Fee Requested:$0.00 ii. Additional Contract Days Requested:0 Day �L 6. 60 Ton of Aggregate added for improved site access and maintenance. a. Since being on-site,WMC purchased and laid 60TN of aggregate to improve site drainage,access,and maintenance. We did this for our workers safety,work-site and facility cleanliness,and to build and maintain a cooperative relationship with the City's neighbor to the west that has been inconvenienced by this job. WMC is not requesting j any additional payment or contract time for this project improvement,however,we hope that the City's perception of this addition is positive and shows a good-faith-effort to complete this project to the City's utmost satisfaction. i. Additional Contract Fee Requested: $0.00 ii. Additional Contract Days Requested 0 Days. If painting is also required for the City to issue WMC's Certificate of Substantial Completion,we would also request that a"Stop Work Order"be issued for the oliday Season. With the Stop Work Order, WMC would not work on site between December o January 5,2020. With the City's approval of these Contract Time Extensions and Stop Work Orders,WMC estimates that Substantial Completion would be obtained on or before January 19,2020 with Final completion achieved by February 22,2020. We have enjoyed working on this job and appreciate the open lines of communication with AE2S and the City of Bozeman Operations(John and Nick). We hope this request is fulfilled to allow us to finish this project with the utmost quality and care for the City of Bozeman. Thank you again for your time and consideration of this request.
