Site work, paving and renovation of a mixed-use development in Irvine, California. Conceptual plans call for the renovation of a municipal facility; for site work for a road / highway; and for paving for a road / highway.

Design-build services are contemplated for improvements to a range in the Irvine, California area with an estimated project magnitude between $1,000,000 and $5,000,000. The work includes upgrading the electrical system by providing and installing a 225-kVA transformer (208Y/120V, 3-phase) and a 600-amp main distribution panel. The project also includes erosion control improvements at the 25-yard and 50-yard ranges, including geotechnical borings, design of compliant erosion control measures such as retaining structures and drainage systems, construction of stabilization measures, drainage installation, and preparation of as-built documentation. Roadway and pavement rehabilitation work includes assessing roadway conditions and drainage patterns, performing milling operations, full-depth asphalt repairs, subgrade stabilization, hot mix asphalt paving, compaction, and final striping for approximately 30,000 square yards of pavement. Restroom renovations consist of the complete renovation of two commercial restrooms, including demolition, framing, waterproofing, electrical work, plumbing, fixture installation, finishes, and accessibility improvements. Water pressure improvements include evaluating the existing domestic water system, designing a solution to increase operating pressure to 60-70 psi, and furnishing and installing new equipment, controls, piping, and backflow prevention devices. Concrete improvements at the 25-yard range include surveying, grading, installation of a new concrete pad, walking paths, reinforced firing lanes, connection to or integration with an existing lead-collection system, and installation of durable lane markings at the 3-, 5-, 7-, 15-, and 25-yard distances. The project requires demonstrated experience with design-build construction of similar scope and complexity, including restroom renovations, water pressure system improvements, slope stabilization and erosion control, concrete pad construction, range marking, electrical upgrades, and asphalt roadway The Method of Contractor Selection has not been determined at this Time. *The value for this project is based on a financial range. The value is listed as the highest possible cost from the range provided by a stakeholder or official project document.
