STATEMENT OF WORK (SOW) updated 6/16/2026 1. Contract Title. Comprehensive Underground Utility Location and Mapping 2. Background. The purpose of this contract is to provide comprehensive Subsurface Utility Engineering (SUE) services in accordance with ASCE 38-22 for the identification, designation, mapping, and verification of underground utilities across the Dayton VA Medical Center property. The property includes approximately 270 acres of federal property consisting of the Dayton VA Medical Center campus, the historic Dayton National Cemetery and the fire station on VA grounds. Portions of the infrastructure date back to 1867. Due to the age, complexity, and incomplete historical documentation of underground systems, a structured, quality-leveled SUE investigation is required to reduce construction risk, prevent utility strikes, and support long-term infrastructure planning. 3. Scope. The Contractor shall provide all labor, supervision, equipment, traffic control, restoration, and professional services necessary to identify, designate, and map underground utility systems across approximately 270 acres including the Dayton VA Medical Center campus and the Dayton National Cemetery. Utility Systems Include: Storm sewer systems Sanitary sewer systems Potable water distribution Fire protection mains Chilled water systems Steam distribution lines Condensate return lines Primary electrical distribution Secondary electrical distribution Natural gas lines Emergency power feeders Telecommunications and data systems Fiber optic infrastructure Site lighting circuits Abandoned or unknown utility lines encountered Underground Storage Tanks Fuel lines coming from above and underground fuel storage tanks Irrigation systems Utility easements Capped landfill Aqueducts Abandoned building foundations Abandoned tunnels 4. Definitions a) Quality Level D (QL-D) Collection and review of all available records including as-built drawings, historical maps, GIS data, central plant records, engineering archives, cemetery infrastructure documentation, historical utility documentation, archived campus records, and available historical site development information. b) Quality Level C (QL-C) Survey of visible surface features and correlation with existing records. c) Quality Level B (QL-B) Surface geophysical designation using electromagnetic locating, ground penetrating radar (GPR), and appropriate conductive/inductive methods. Horizontal location markings and digital capture required. d) Quality Level A (QL-A) Vacuum excavation (soft dig) test holes to confirm horizontal and vertical location, depth to top of utility, material identification, photographic documentation, and full restoration. 5. Campus Conditions. The Contractor shall account for active 24/7 hospital operations, high-voltage electrical systems, pressurized steam and condensate, fiber optic backbone systems, burial areas within cemetery grounds, and infrastructure of varying age and material.
