I have worked for main contractors for the majority of my 40-year career
As such I have seen the frustrations of trying to submit winning competitive bids - sometimes successfully - but often finding on many occasions that we have finished second, third, or worse, and that the winning bid is significantly lower than the second-place bidder. Is it not time for clients to introduce a mechanism to accept the second-lowest compliant bid?
This would stop suicide bids, negate the client’s need to have a minimum contingency of the difference between the accepted tender sum and the second place bid amount, and help to avoid the probable - if not inevitable - contract period and beyond time of aggressive, confrontational behaviour between all parties in the supply chain.
This won’t put a stop to all issues as the second-place successful contractor may still resort to confrontation rather than the more enlightened partnering principles the industry has been trying to achieve, but it won’t be because of suicide bidding.
