The Contractor is hereby directed to make the herein described changes from the plans and specifications and/or perform the following described work not included in the Plans and Specifications for this project.
WRF3 Sewer Lift Station
Department of Water and Power
CONTRACT CHANGE ORDER NO. 2
Construct a sewer lift station.
69880572
DESCRIPTION
Install soldier beam and steel plate shoring system in
unexpected groundwater conditions.
CONTRACT VARIANCE SUMMARY
The exploratory work performed by NMG Geotechnical, Inc. in May 2017 for the geotechnical study and report included two borings to 27 feet below ground surface (BGS). No groundwater was observed in either boring. The geotechnical report was provided as an appendix to the bid documents and a reference for contractors bidding the job. The shoring sub-contractor began drilling the first soldier pile for the shoring system on 2/22/2021 and encountered groundwater on 2/24/2021. The remaining work encountered groundwater consistently at 21 ft BGS. The shoring system design prepared by the shoring sub-contractor includes installation of 22 soldier piles to approximately 37 feet below ground and steel plates and lagging between the piles to approximately 27-30 feet below ground. The productivity impact caused by the unknown groundwater conditions has been estimated at 4.5 hours per soldier pile plus additional equipment and materials costs based on daily inspection records and cost information provided by the contractor. The contract change order for $130,394.49 includes all extra work of any nature associated with installation of the shoring system. The contractor has requested 84 noncompensable additional working days on the contract.

Subject: Proposal for Changed Conditions - Revised
As outlined in our original cost proposal, and subsequent correspondence, PHC considers the ground water we have encountered at approximately 21ft below ground level to be a changed condition to the contract.
Additionally, after consideration and discussion with McMahon we also feel that consistent refusal at 21ft +/- rather than 27ft as noted in the soils report to be changed condition as well and further impacting our ability to deal with the groundwater. In consideration of these changed conditions, we have attached the following cost proposal which is summarized as follows:
TOTAL Extra Work.................................................................. $169,978.80 As noted by McMahon in their cost proposal narrative (also attached) we have proceeded to maintain production and move forward on the shoring holes in good faith with the expectation that our request for extra work will be considered justified and that we will work together to finalize this change order in a spirit of cooperation and good faith. It is our hope that we can finalize this change promptly as our subcontractor is incurring significant unexpected additional cost which deserves compensation.
As for time impact, PHC has prepared a schedule update for progress through April 8, 20201 which allows 3 weeks for pit excavation starting April 19th, 2021. We would propose to use this updated progress schedule as the basis for a no-cost time extension to the project completion with a new project completion date of March 1, 2022.
Further to our earlier correspondence, McMahon has enlisted the help of Cornelius Consultants to assist them in their presentation of facts related to their request for additional compensation due to changed conditions. The full report is attached for added information. The attached report has certain key sections highlighted which are paraphrased as follows:
• Cornelius points out that “refusal” to the relatively small CME-75 geotechnical drill would not necessarily mean refusal to the more powerful MAIT HR130 rig first employed by McMahon. • Cornelius clarifies the Plan A and Plan B approaches envisioned by McMahon to deal with the indicated soils and expected gravel/cobble layer below 27ft with “Plan A” being to utilize a continuous flight auger to drill to 27ft without extracting soil and then vibrating beams to depth through loosened soil and beyond through the gravel/cobble layer to completion. If gravel/cobble prohibited vibrating the beams, then “Plan “B would provide for removal of soil from the holes with the continuous flight auger making multiple passes. In neither case, did McMahon consider anything less than 4 holes per day in their plans. • From the start, McMahon instead discovered that at a depth of just 21ft, drilling became “markedly different” indicating that the auger was encountering much larger material than indicated or anticipated.
Additionally, subsequent investigations confirmed the presence of groundwater at 21ft. The combination DocuSign Envelope ID: 79225A20-BF10-4B73-B3DF-ECC43A56F7D5

of groundwater and cobbles/boulders caused the shaft walls to collapse. • Continued attempts to advance drilling below 21ft resulted in inconsistent return of soil being removed to the surface with the water washing even the sandy soil off the flights leaving very little to be spun off at the surface.
• In consultation with our dewatering expert (Rain-for-Rent) and out of an abundance of caution, it was determined that using slurry may have a detrimental effect on our dewatering efforts. Therefore, PHC did advise McMahon that drilling slurry would not be allowed for the 22ea holes. Additionally, in discussing with McMahon at the time, it was decided that the significant additional cost of adding slurry to the drilling operation (not part of their cost proposal) would likely not offset any potential time savings.
In summary, while PHC and McMahon appreciate the offer of 1.5hrs/hole as additional compensation, we feel that that amount is far short of reasonable compensation for this unfortunate changed condition. Given that McMahon’s production rate diminished drastically from even their lowest anticipated rate of installation to barely 1 per day, we respectfully request that the City consider allowing 5.0hrs/hole with the other 3.0hrs/hole providing compensation for both the changes in equipment and the extra time/expense experienced when drilling from 27ft to completion.
Per McMahon, the reason for the increase from 4.0hrs to 5.0hrs is justified as Cornelius Consultants discussed in the Differing Site Conditions letter that if it took approximately 15 - 20 minute to get from 0’ to 21’, and you could reasonably estimate another 5 to 10 minutes to reach 27.5’ if there was no groundwater or refusal present between 21-27.5. With this timing in mind, it’s a fairly conservative estimate to core a dry hole an additional 7.5’ to
9.5’ in 2 to 2.5 hours seems more than reasonable timeframe. With that noted, that left McMahon with 5 hours of added time to complete each shaft with refusal and groundwater starting at 21’.
Additionally, per the original proposal comments, McMahon has attached and highlighted the labor and equipment rates that were incurred while drilling.
It should be noted that in the spirit of cooperation, PHC is requesting a non-compensable time extension. In addition, PHC has not included our additional cost for manpower and equipment needed to support this extended time spent drilling and setting these beams. While we have been somewhat productive with potholing efforts and building the block wall, this is far short of the total additional effort needed to support the extended drilling time.
As requested, PHC will prepare and forward a separate cost proposal for dewatering of the completion of our “test well” dewatering efforts and return of RFI 009 (Structure backfill).
