Costing assumptions
AS 2634-1983 / BS EN 13121 — pending manufacturer data
AS 2634-1983 Table 3.1 — the minimum wall for that DN
the flat wall when the basis is the default; the alternative is the AS 2634-1983 Table 3.1 minimum
R = k·DN — AS 2634-1983 gives no bend radius factor
branch DN = factor × DN where not stated
used only where AS 2634 Table 3.1 does not tabulate the DN
a longer straight run is split into spools
SS316 A4 — editable; 15 USD/kg default (no vendor price in this project)
on the GRP component cost
fallback where the vendor table gives no rate
fraction of the base subtotal (0.35 = 35 %)
fraction of the base subtotal (0.20 = 20 %)
fraction of the base subtotal (0.10 = 10 %)
fraction of the base subtotal (0.10 = 10 %)
lump sum
Values in force; the report prints the same numbers. The weight allowance applies to the GRP component cost only. Wall thickness basis in force: —.

on the HDG base rate
