The construction BN are an easy pool of manpower if you still have them
maybe keep like 10 or 20 batt. just in case.
Remember your construction also help digging fortifications - at least did, still do if there are no more bugs or will when they are fixed. If the choice is a combat unit behind lines digging or some construction units helping another onmap unit doing the same they are much more economical.
If you are relying on building a big hard wall in your rear for defence, getting rid of construction is getting rid of your best way of building it.
