Exterior Drainage Does water stand on the property for more than 24 hours after a heavy rain? Yes No Unknown Comments Are gutters and downspouts in good repair? Yes No Unknown Comments:
Road Surfaces (1) Grade, shape, crown, and/or outslope surface and shoulders.
Groundwater The groundwater shall not be degraded as a result of the waste maintained at the facility.
Surface Grade and shape the road surface, turnouts, and shoulders to the original shape on the TYPICAL SECTION SHEET. Inslope or outslope as directed to provide a smooth, rut-free traveled surface and maintain surface water runoff in an even, unconcentrated manner. Blading shall not undercut the backslope or cut into geotextile fabric on the road. If required by the Contract Administrator, water shall be applied as necessary to control dust and retain fine surface rock. Surface material shall not be bladed off the roadway. Replace surface material when lost or worn away, or as directed by the Contract Administrator. Remove shoulder berms, created by grading, to facilitate drainage, except as marked or directed by the Contract Administrator. For roads with geotextile fabric: spread surface aggregate to fill in soft spots and wheel ruts (barrel spread) to prevent damage to the geotextile fabric.
Fill, Backfill and Landscaping No soil found on Site, or transported to the Site from remote locations, which contains debris or waste or Hazardous Materials shall be used for fill, backfill or landscaping topsoil.
Potable Water Contractor shall provide potable water and ice for the Stage 2 Site use, and ensure that a safe and plentiful supply of potable water and ice is available for all activities on the Stage 2 Site until Substantial Completion of Subproject 3. The water and ice for human consumption shall be of suitable quality.
Compaction of surfaces 5 Compaction of ground surface under floors etc including scarifying for a depth of 150mm, breaking down oversize material, adding suitable material where necessary and compacting to 95% Mod AASHTO density. m2 96
Wastewater i.e. wastewater and storm water collection, treatment and management systems.
Prohibition Against Selecting and Installing Products Containing Hazardous Materials The Contractor shall not select, install or otherwise incorporate any products or materials containing Hazardous Materials within the boundaries of the Site. Should the Contractor or any Subcontractors have knowledge that, or believe that, an item, component, material, substance, or accessory within a product or assembly selected by the Contractor or any Subcontractor may contain Hazardous Materials it is the Contractor’s responsibility to secure a written certification from the manufacturer of any suspected material which identifies the specific Hazardous Material(s) contained, together with the Material Safety Data Sheets (MSDS) for such materials which shall be submitted to the Owner and Design Professional.
Drainage ▪ Prevent silt bearing road surface and ditch runoff from delivering sediment to any streams or wetlands. ▪ Maintain rolling dips and drivable waterbars as needed to keep them functioning as intended. ▪ Maintain headwalls to the road shoulder level with material that will resist erosion. ▪ Maintain energy dissipaters at culvert outlets with non-erodible material or rock. ▪ Keep ditches, culverts, and other drainage structures clear of obstructions and functioning as intended. ▪ Inspect and clean culverts at least monthly, with additional inspections during storms and periods of high runoff. This shall be done even during periods of inactivity. Preventative Maintenance ▪ Perform preventative maintenance work to safeguard against storm damage, such as blading to ensure correct runoff, ditch and culvert cleaning, and waterbar maintenance.
