Widening and strengthening
The existing road (a surveyed layer) and its carriageway edges – typed, or from point remarks such as EOP or EDGE – and the new carriageway: its edges, crown and camber. The crown level comes from the formation / vertical alignment, or is as low as the overlay allows over the old road.
Over the old carriageway the overlay layers (BC, DBM …) go on a profile corrective course where the old surface is low; where it is high it is milled. The widening strips get the full crust (BC, DBM, WMM, GSB …) with box cutting under it, or filling where the bottom of the crust is above the ground.
The preview shows the section with the new surface and the bottom of the crust; the table the volumes (average end areas) and this section's areas. Write the layers puts the new surface and the bottom of the crust into their layers; the items can be priced in the BOQ (Widening and strengthening).

CXWIDENWidening and strengthening of a road…
An existing road widened and strengthened: the new carriageway with its camber, the overlay (BC, DBM …) with a profile corrective course where the old road is low and milling where it is high, the full crust (BC, DBM, WMM, GSB …) of the widening strips with box cutting or filling under them – section by section, volumes, an Excel report and BOQ items.
CXBOQBill of quantities with rates…
The bill of quantities: schedule items with unit and rate, each quantity from the sections (cutting, filling of any area combination, turfing, benching, overhaul, spoil, borrow) or typed – amounts and total live, Excel BOQ with formulas.
CXFORMATIONFormation levels / vertical profile…
Formation levels and PVIs with vertical curves, best-fit grade, L-section preview.
