For the construction arm far more than the FM concerns, intelligent journos have started to pick up on the impact of the firm's collapse on other than direct employees. The real pain is likely to be felt by sub contractors and suppliers - with an impact on tens of thousands of people working for smaller firms carrying out specialist works for the fallen behemoth.
Subbies are always the last to be paid anyway, and have the longest wait for their money as main contractors will generally not pay until their own monthly claims have been passed, and even then may pay only a percentage, with their own retention in place. Main contractors who have won work by underbidding will also squeeze subbies already contracted. I know from personal experience how very close to the edge many subbies on big jobs walk.
Ideally, if the job is to be finished, the subcontractors will be novated to the new main contractor on the same terms - but even this takes time, and when it is likely that Carillion haven't paid them for three months (and they may end up with nothing) the prospect of waiting another three for a payment from a new principal contractor will force many to the wall.
Clients will only find main contractors to replace Carillion on cost-plus terms if continuity is to be maintained; there is simply no time to cost and negotiate new contracts. And rescue firms will know they must secure rock solid fee agreements now, up front; clients happy to agree crash costs at times of crisis will always backtrack once the hiatus of the rescue is over; getting it sewn up tight whilst you have the advantage is the only way.
And make no mistake, it's the clients that will pay. As long as the crash costs now are equal to or less than costs of demobilising the schemes, mothballing, re-tendering and re-mobilising, with all the substantial costs of delayed delivery, they will pay. And that means us - taxpayers - in many cases. There really is no alternative. The least-cost options will still cost us a fortune.
