- 20:02, 19 July 2022 diff hist +1,030 N As-built surveys Created page with "Throughout the construction process, it is sometimes necessary to deviate from the intended design of LID features and adapt the design to on-site conditions. The completion of a post-construction as-built survey is a standard operating procedure for engineering projects that captures any changes made to the feature’s design during construction.<sb> Survey Steps: #Use the same datum as the pre-engineering survey #If a pre-engineering survey is not available, use a ref..."

They protect building foundations or other subsurface infrastructure. They also prevent infiltration through contaminated soils. Where building foundations next to the LID feature are not waterproofed, liners can be used to protect adjacent infrastructure.<br> Construction Steps:<br> #Compact 30 – 50 mm of sand over the soil onto which the membrane will..."

Their design is determined by the drainage requirements of the feature. Construction Steps: 1. Install the underdrain to grade with a consistent slope of 0.5% to 1.0% 2. Connect overflow risers with single-elbowed ‘y’ connections or 45° elbows 3. Situate maintenance risers where siltation is expected in drain lines (such as a..."
