Yes! IMHO this one is an easy fix
Here's how I deal with this particular Safeguard kink ....
1)Accept that they are not going to approve or pay us to do work like installing new double paned glass, and bid for what Safeguard is asking us to do. Give yourself some peace of mind by stating the scope of work in your bid; "reglaze 1 broken window 32x29" using single paned glass" or "install 1 new sheet of single paned glass 32x29" etc.
2)Bid over the allowable or price list amount, state that on your bid and also state why you feel it is justified. You can do this for ALL Safeguard bids but here I'll just stick to window reglazing.
"Reglaze 1 broken window 32x29" using single pane glass. Unable to complete per allowable due to increased cost of materials needed."
"Reglaze 1 broken window 32x29" installing new single paned glass. Unable to complete per price list due to increased cost of materials needed. Special order glass is required due to size, this has increased the bid amount needed."
Like I said use this for any Safeguard bids you want. Bid over the allowable price and state that you can not complete per allowable and why. Need a chainsaw? Requires commercial equipment? Going to use a bush hog? Extra labor needed to move from rear fenced yard? Glass shop required due to size? Say so! If you give this statement on your bids you'll see alot less of those "your bid has been reduced" notices.
