Exterior

Poor
Exterior Structure: Cracking is observed in the exterior masonry walls, as mentioned in other areas an engineering study should be performed. Additionally, re-seal the building envelope by regrouting or repointing the masonry work, filling holes, and replacing cracking or missing caulking around penetrations.
Poor
Foundation: There are indicators of foundation movement, recommend engineering study to determine cause and proper mitigation. Promote stable soil conditions around foundation by creating positive storm water drainage away from structure and eliminating standing water next to foundation.
Fair
Parking/Traffic: Slurry coat asphalt roadway surfaces and restripe all surfaces. Repair, slurry coat, and paint asphalt parking surface.
Fair
Site: Repair uneven pedestrian paved surfaces to reduce potential tripping hazards. Various playground equipment needs to be updated and repainted. Repair rubber fall zone material and add additional fall zone material to all playground areas. Review and consider Safety & Security Recommendations on the Facility Details page.
Good
Doors: Refresh interior finished wood door surface as needed. Refresh exterior rollup metal door finished surfaces as needed.
Fair
Exterior/Interior Windows: Replace damaged fiberglass window systems.
Fair
Roof: The two roof systems at Mambrino are expected to reach their life expectancy in 2029. The single-ply roof currently shows minor bubbling and uneven surfaces, with signs of detachment from the deck in some areas. These issues should be addressed by securing the roofing in accordance with the manufacturer’s recommendations. All piping supports on the roof should be inspected and either repaired or replaced as needed. For the standing seam metal roof system, fasteners and caulking should be checked for tightness and proper sealing, with repairs or replacements made where necessary. Vegetation overhanging both roof systems should be trimmed back to prevent damage and maintain clear access. Ongoing maintenance should follow the manufacturer’s guidelines, and the roof should be inspected at least twice a year and after any significant weather events.

Interior

Poor
Interior Structure: There is evidence of slab cracking and movement throughout the building. An engineering study is recommended to determine the cause and possible solutions. Additionally, repairing and sealing the cracks in the floor is required after mitigation is completed for the foundation, continue to observe for movement. Cracking observed in masonry work, utilize engineering study to determine level of action to repair or replace masonry partitions as needed. Cracking observed in framed partitions of the interior walls, repair walls, fill gaps and refinish surface; observe for movement. Deep clean, repair or replace ceramic wall tile, re-grout, and re-seal surface. Refresh high touched interior masonry wall finished surfaces. Refresh wallboard paint wall surface and repair as needed. Replace stained or damaged 2x2 lay-in ceiling tiles as needed., Repair and refinish wallboard ceiling surfaces as needed.
Good
Plumbing: No issues observed or reported.
Good
ADA: No issues observed or reported.
Fair
Furnishing, Fixtures, Equipment: Repair or replace aged or damaged lockers, cabinets, and countertops as needed. Update restroom accessories and stalls as needed.
Fair
Electrical: Update lighting fixtures to LED. Update master control panel, wiring, and PA system components as needed. Review and consider Safety & Security Recommendations on the Facility Details page.
Fair
Safety/Security: Review and consider Safety & Security Recommendations on the Facility Details page.
Fair
Flooring: Deep clean, repair or replace ceramic tile flooring, re-grout, and re-seal surface. Deep clean, repair or replace aged and damaged vinyl tile flooring. Deep clean and replace aged and damaged carpet flooring as needed.
Poor
HVAC: During the summer of 2025, the district completed a significant upgrade by replacing 36% of the total HVAC tonnage at the campus. However, the remaining 64% of the system is at or beyond its expected service life. To ensure continued reliability and maintain energy efficiency, it’s strongly recommended that the district begin developing a phased replacement strategy. As new HVAC units are installed, it’s important to update the Energy Management System to ensure seamless integration and optimal performance. Additionally, all newly installed equipment should undergo testing and balancing to confirm that each unit is operating efficiently and in alignment with design specifications.
