hi john
no cis is in top of that,
all trades contracts have between 5% and 10% retention, and when the house bubble burst 20 months ago, developers wrote to a lot of trades asking them to write off the retentions.
some even asked trades with monies owing to re invoice at discounted rates, and then asked to retender at a prescribed level, if they didnt do this then they just went to another contrator.
bearing in mind that build cleans were already extremely tight, it is difficult to imagine how that was achieved.
regards
martin
