Natural Gas Uprating

The City of Mesa is seeking professional services to assess and potentially uprate the maximum allowable operating pressure (MAOP) of its high‑pressure “Magma” natural‑gas distribution system. The contractor must conduct a comprehensive study—including records review, GIS data analysis, interviews, site visits, potholing planning, and a gap analysis against CFR 192.619/192.624 TVC criteria—to determine the current MAOP, identify feasible uprating options, and produce a detailed implementation plan. The award is a single‑vendor, time‑and‑materials contract valued at approximately $107,400, with a base term of two years and an optional one‑year renewal. • Scope: MAOP determination, uprating feasibility, regulatory compliance plan, and related data‑handling (OCR scanning, GIS). • Deliverables: Final report with current MAOP, recommended new MAOP, asset replacement/reinforcement recommendations, and a TVC compliance gap analysis. • Requirements: Minimum 6 on‑site working days in Mesa, use of City‑provided GIS geodatabase, OCR‑processed scans of needed records, and coordination for potholing activities.
