MEASUREMENT AND PAYMENT STANDARD SPECIFICATION ROADWORKS DoI REFERENCE TEXT December 2015 Page 153 23.10 SLURRY SURFACING Payment will be made at the tendered rates for the actual quantity of accepted slurry surfacing mix spread. Measurement; - Slurry surfacing laid per m2 @ average 9 mm thickness, including surface preparation and supply and laying of slurry surfacing mix. - Slurry correction volume per m2. 23.11 MISCELLANEOUS CONCRETE Make allowance for excavation, bedding and backfilling in the following items. 23.11.1 Footpaths Measured in linear metres for each type. 23.11.2 Vehicle Crossings and Access Strips Measured in square metres for each type. Make allowance for reinforcement. 23.11.3 Kerbs and Gutters Measured in linear metres for each type (any drainage structures/crossings excluded from measured lengths.) 23.11.4 Inverts Measured in linear metres. 23.11.5 Wheelchair Crossings Measured by number. 23.11.6 Traffic Island and Median Infill Measured in square metres. 23.12 DRAINAGE WORKS 23.12.1 Excavation in Trenching Measured in in-situ cubic metres for the specified range of depths to invert. The length of the trench shall be measured between the outside face of headwalls or between the centre of pits. The width of the trench shall be the outside width of the culvert plus 300 mm on each side. The depth of the trench is the average of the depths to invert measured at the structure at each end of the section. The depth to invert is the lesser of the depth below natural surface and the depth below finished surface level. In the case of kerbside structures, the finished surface level is measured at the top of kerb. Make allowance for shoring, bedding, inlet and outlet structures and irregularities in the natural surface where applicable. 23.12.2 Supply, Load, Transport, Bed, Lay and Backfill Culverts Measured in linear metres along the invert of the culvert as the distance between the outside face of headwalls or other structures for the type and size scheduled. Multiple barrel culverts are measured as the single distance between the outside face of headwalls or other structures. Excavation is measured separately. 23.12.3 Excavate, Supply, Load, Transport, Bed, Lay and Backfill Culverts Measured in linear metres along the invert of the culvert between the outside face of headwalls/inside face of pits or other structures for the type and size scheduled. Multiple barrel culverts are measured as the single distance between the outside face of headwalls or other structures. Make allowance for RC floor slabs for precast box culverts. 23.12.4 Concrete Headwalls, Maintenance Holes and Other Structures Measured in cubic metres. Measured by number. 23.12.5 Collar Joints, Bandage Joints, Anchor Blocks and End Caps Measured by number. Make allowance for splay ends. 23.12.6 Inlet and Outlet Channels Measured in in-situ cubic metres. Not measured separately for culvert waterways less than 2 square metres in cross-sectional area and channels less than 50 metres long. 23.12.7 Open Unlined Drains Measured in in situ cubic metres. 23.12.8 Subsoil Drains Measured in linear metres. Make allowance for blocks, headwalls, filter material, geotextiles, and connection to existing drainage system. 23.12.9 Demolish and Remove Existing Drainage Structures Measured as an item. Make allowance for backfilling. 23.13 PROTECTION WORKS 23.13.1 Geotextile Fabric Measured in square metres of completed area. Make allowance for supply and placement. Make allowance for laps and folds. 23.13.2 Stone Pitching Measured in square metres of the face area.
