Report
Summary
This project includes the removal and replacement of concrete pavement panels in the Terminal 4 North Apron area that are displaying degradation from a chemical alkali-silica reaction (ASR). ASR occurs in Portland Cement Concrete Pavement when a certain type of silica sand is used in the rock material as part of the concrete mix. The concrete panels were placed in 1989 and ASR has resulted in accelerated deterioration of the pavement, as evidenced by surface cracking and spalling. Airport staff has been actively and systematically replacing the impacted concrete panels, based on funding availability. This is a multi-phased project that will span several years consistent with Federal Aviation Administration grant funding.
The Consultant, CH2M Hill Engineers, Inc. (CH2M Hill) will function as an extension of staff to attend coordination meetings with the designer, Construction Manager at Risk (CMAR) and stakeholders, provide constructability reviews, review and evaluate the CMAR's schedule, project sequencing, inspection, reporting, documentation, and the closeout process for the project.
Procurement Information
CH2M Hill was chosen for this project using a qualifications-based selection process according to section 34-603 of the Arizona Revised Statutes.
Contract Term
This phase of services is expected to take approximately two years to complete.
Financial Impact
CH2M Hill's fee for this phase of the project will not exceed $1,650,000, including all subconsultants and reimbursable costs. Contract payments may be made up to contract limits for all rendered contract services, which may extend past the contract termination.
