Why New Subcontractors Take Two Weeks to Get on Site
When a programme requires new subcontractors, the cost of the delay to get them on site is rarely calculated but always felt. The bottleneck is almost never availability. It's the paperwork.
The programme cost of slow onboarding
In construction, time on programme is money in a way that is rarely true in other industries. A subcontractor who should be on site on Monday but doesn't start until the following Wednesday has introduced a two-day slip before they've done a single hour of work. On a tight programme with follow-on trades, that slip compounds quickly: two days becomes five, five becomes ten, and the project manager is managing client expectations about a delay that could have been avoided entirely.
the Health and Safety Executive's guidance on pre-construction planning is explicit: the time spent ensuring subcontractors have the correct qualifications, insurances, and induction records before they arrive on site is not optional. It is a legal and commercial obligation. But the way most construction firms fulfil that obligation (manually, by email, chasing documents one by one) introduces delays that are structural, not incidental.
What the manual process looks like
The typical subcontractor onboarding sequence in a construction business involves collecting a defined set of documents: CSCS cards, public liability insurance, employer's liability insurance, method statements, risk assessments, and site-specific induction records. Each of these has to be requested, received, checked, filed, and confirmed before work can begin.
In practice, this means an email requesting documents, a wait for them to arrive, a chase when they don't, a check to ensure they're in date and valid for the scope of work, a follow-up for anything missing or expired, and a manual update to whatever system (often a spreadsheet) is being used to track compliance. Multiply that across five or ten subcontractors on a single project and the administrative burden becomes significant.
The person managing this process is typically the same person managing the programme, ordering materials, and fielding client queries. The paperwork waits because everything else is more pressing, until it can't wait any longer and the start date slips.
The compliance risk in a manual system
Beyond the programme impact, a manual compliance process carries a risk that is easy to underestimate in a busy period. Documents that were valid when they were collected expire. Insurance renewal dates pass unnoticed. A subcontractor whose CSCS card lapsed six months ago is on site because nobody checked when they moved from one project to the next.
For principal contractors, the liability implications of having an unqualified or uninsured subcontractor on site are material. They are also entirely avoidable, but only if the compliance tracking system can do something a spreadsheet cannot: alerting the right people when something is about to expire, before it already has.
What an automated onboarding system handles
Construction businesses that have automated their subcontractor onboarding describe the same outcome: from the moment a subcontractor is confirmed, they receive a structured, automated request for every document they need to provide. Reminders go out automatically if documents aren't received within a defined window. Once everything is in, the relevant person is notified and the subcontractor is cleared to start, without a single chasing email being written manually.
Expiry dates are tracked automatically. Ninety days before a certificate or insurance policy expires, the subcontractor receives a renewal reminder and the site manager receives a flag. Nothing falls through the cracks because nothing is relying on someone remembering to check.
The result is a faster, safer, more consistent process, and a site manager who is spending time managing the project rather than chasing paperwork.
