Provide utility line depths, bedding, and backfill as required by applicable requirements and geotechnical recommendations. Minimum cover over pipes is 0.6 meters; greater than frost penetration; or sufficient to support imposed dead and live loads for the pipe materials used; whichever is more stringent. Place plastic warning tape along the route of the buried pipe after installation at a height of 0.3 meters above the pipe.

Coordinate all required installation, relocation, improvement and protection of utilities held by third party (e.g. public or private utility). This includes coordination of any work to be performed by the utility owner. Choice of materials and products for utility installation must be coordinated with the utility owner (customer or third party) to ensure proper integration and compliance with existing systems and allow for easy maintenance and repair of the utilities in the future.

Provide utility materials per IBC requirements. Provide corrosion protection for utilities that provides the minimum life expectancy specified in Section 1.0- GENERAL. Any piping or equipment exposed to sunlight must be coated with protective coatings suitable for UV exposure with a minimum expected coating life of 10 years before recoating.
