Beware of D1.5 limitations on Both Engineer acceptance of previous WPS's (SWPS) which will not provide the PQR's behind them, and the limitations on what type of WPS's may be prequalified in D1.5
It would be wise to pass this SWPS idea by the authority in jurisdiction to see if they will accept or not.
5.2.3
The Engineer may accept evidence of previous WPS or
pretest and verification qualification testing, provided (1)
the PQR (procedure qualification record) is complete and
shows compliance with the requirements of these specifications,
and (2) the results of the tests are certified as
accurate by a state representative or an independent third
party acceptable to the state.
