Subject: PCO 024 – Cost Proposal for Reinternment
Mr. Luna:
In response to your Change Order Request dated January 15, 2025, we are pleased to offer the following proposal for reinternment. Please see below for PHC’s T&M proposal for the Reinternment process.
Since we don't know how long the reinternment process will take, The City and PHC have agreed to an estimated price of $500,000.00 to complete this work. If the process takes longer or shorter than what is noted in the daily rate breakdown below, will adjust accordingly.
This proposal includes a daily rate for assuming that the highlighted items (see attached rate sheet) will be onsite the duration of the project.
Pending the need for any additional equipment these will be marked up on the T&M sheet and noted in PHC’s Daily Log. If any of the highlighted items are either not needed or removed from site, this will also be captured on daily extra work sheets. We would ask that these extra work sheets be signed daily by the City’s representative.
This Daily Rate proposal includes the following:
• Equipment, Labor
• Temp Facilities (Toilets, Office Trailer, Temp Fence) Items that may be required but are not captured in this proposal are as follows:
• MISC Materials
• Any additional services not noted, but may be required Refer to the breakdown below for Mobilization, Estimated Daily Rate, Safety Training, Trucking Export, and Demobilization:
Mobilization Costs: ......................................................................................... $25,000.00 Daily T&M Rate Costs:........................................................................................ $448,000.00 • Totaling the other costs, PHC will have 32 days at $14,000/day to complete the reinterment Safety Training for MLD’s ................................................................................... $1,100.00 Trucking Export Costs: ........................................................................................ $14,375.00 • Estimated 25 Loads @ $500/load per City Request for Reinternment Document.
