New Mexico Navajo South Agency Tohaali Community School – WO# AB856959 Highway 491, Route 19 Newcomb, New Mexico 87455 Statement of Work (SOW) 09/02/2026 Concrete Sidewalk Demolition and Replacement

Overview Tohaali Community School is in need of demolition and replacement of deteriorated and damaged concrete sidewalk sections located on the school campus. The existing concrete sidewalk is not ADA-compliant, has areas of cracking, spalling, settlement, deterioration, and/or other deficiencies that create uneven walking surfaces and may present trip hazards to students, faculty, staff, visitors, and school maintenance personnel.

The purpose of this project is to remove the identified defective concrete sidewalk sections and replace them with new concrete sidewalks that provide a safe, ADA accessible, durable, level, and accessible pedestrian walking surface.

The Contractor shall field-verify the existing sidewalk conditions, dimensions, quantities, elevations, drainage requirements, adjacent structures, utilities, and other site conditions prior to beginning work.

The completed sidewalk shall provide a durable pedestrian surface and shall be properly integrated with existing sidewalks, curbs, entrances, drainage areas, and surrounding grades.
