Report
Summary
The purpose of the project is to relocate existing City water and sewer infrastructure associated with the construction of South Mountain Freeway (SR202L). The project includes relocation of approximately 23,000 linear feet of various sized water mains, 9,000 linear feet of various sized sewer mains, and installation of water distribution and transmission mains, with associated appurtenances and portions of the sewer collection system. The Arizona Department of Transportation (ADOT) is managing Design Services separately.
These amendments are necessary because Wilson Engineers, LLC and Brown and Caldwell, Inc. have encountered several factors with more significant impact than anticipated. Amendment 2 further addresses utility relocation design that has fallen behind the original schedule and the design review packages that required additional reviews which were not originally anticipated. ADOT's freeway contractor also experienced considerable challenges meeting the schedule and completing construction work for water and sewer relocation associated with the freeway project. Additionally, Wilson Engineers, LLC's and Brown and Caldwell, Inc.'s level of involvement with field work and inspection hours has been higher than was anticipated. Due to these issues, Wilson Engineers, LLC and Brown and Caldwell, Inc. have expended funding quicker than expected. These amendments will provide additional funds to the agreements.
Contract Term
The term of these agreement amendments will add an additional 90 calendar days from issuance of the Notice to Proceed. Work scope identified and incorporated into the agreement prior to the end of the term may be agreed to by the parties, and work may extend past the termination of the agreement. No additional changes may be executed after the end of the term.
Financial Impact
- The initial agreements for Design Review and Construction Inspection Oversight Services for Wilson Engineers. LLC and Brown and Caldwell, Inc. were executed for a fee not to exceed $900,000 each, including all subconsultant and reimbursable costs.
- Amendment 1 increased the agreement value by $759,642 for Wilson Engineers, LLC and $375,000 for Brown and Caldwell, Inc., including all subconsultant and reimbursable costs.
- Amendments 2 will increase the agreement by an additional $442,000 for Wilson Engineers, LLC and $394,000 for Brown and Caldwell, Inc., for a new total not-to-exceed agreement value of $2,101,642 for Wilson Engineers, LLC and $1,669,000 for Brown and Caldwell, Inc., including all subconsultant and reimbursable costs.
Funding for these amendments is available in the Water Services Department's Capital Improvement Program budget. The Budget and Research Department will separately review and approve funding availability prior to execution of any amendments. Payments may be made up to agreement limits for all rendered agreement services, which may extend past the agreement termination.
