In this proposal to amendment the existing preconstruction services contract, we have prepared a detailed scope of work (Attachment 1) and schedule of values (Attachment 2) for your final review and approval. Based on the current schedule established with City and Hazen staff, we are assuming an additional 6- month preconstruction services duration commencing in January 2026. We have used Exhibit A CM@Risk Pre-Construction Services Scope of Work document and Archer Western’s past experience to develop the requirements and corresponding schedule of values. Archer Western will continue to invoice monthly with back-up information provided as described in the scope of work. Allowances will only be used upon written approval from the City. We are looking forward to continue providing exceptional preconstruction services to ensure the City and Hazen are provided with the greatest value for the Pecos WTP and ongoing operations. In your review, please let us know if you have any questions/comments or if you need additional information to complete the review. Respectfully, Nathan Antonneau, P.E.
