Man hours, counted not estimated

Ask a utility contractor how many man hours went into a particular site and you will usually get a calculation rather than a number. Four on the crew, roughly two weeks, call it three hundred and twenty. It is derived from the plan, not from what happened. It does not include the day two of them were pulled onto another job, or the three days the crew was stood down, or the supervisor who was there every morning for an hour.

Everyone knows the number is approximate. It still ends up in the cost report, the client report, and the next bid.

Check in, check out, and the number counts itself

In Utility Work X, everyone attending a site checks in when they arrive and out when they leave — operatives, supervisors, subcontractors, visitors. That is it. There is no separate timesheet exercise and no additional admin task at the end of the week.

What comes out of it is the actual hours worked on each site, by each person, by each company, on each day. Not the planned hours. The real ones. Because Utility Work X is structured by project, scheme, site and micro site, those hours roll up cleanly to whatever level you need to look at — one excavation, one street, one scheme, one framework.

Why does accurate man-hours data matter?

Three reasons, in ascending order of how much they are worth.

Costing. Labour is the largest controllable cost on most utility work. If the hours attributed to a site are estimated, the cost of that site is estimated, and so is the margin. Actual hours make the cost report something you can defend rather than something you present.

Bidding. The most valuable thing a contractor owns is an honest record of how long its own work actually takes. Every estimate is a guess made more accurate by evidence, and every scheme completed with real hours attached makes the next estimate better. Contractors who price from real data stop winning the jobs they should have lost.

Safety reporting. Accident frequency rate is calculated per number of hours worked. The hours are the denominator. If they are estimated, the safety statistic reported to clients, to the board and in prequalification is built on an estimate — and it is the number that most often decides whether a contractor stays on a framework. A denominator produced automatically from site attendance is one that stands up to scrutiny.

The questions this answers that nobody could answer before

How many hours did that scheme actually consume against what we priced? Which sites take consistently longer than planned, and what do they have in common? How many hours has a particular subcontractor delivered this month, and does that reconcile with what they have invoiced? Who was on site on the fourteenth?

That last one stops being a filing question the moment something goes wrong. When a client, an insurer or the HSE asks who was present at a specific site on a specific day, the answer is either a searchable record or a week of phone calls.

Does site check-in mean tracking staff?

No. Check-in and check-out records attendance at a site — the same information a signing-in sheet at a compound gate has captured for decades, and for the same reasons: you need to know who is on site in an evacuation, and you need an accurate record of who was present. It is not continuous location monitoring and it is not a productivity score. It is attendance, held properly, in a system where it can actually be used.

It is also worth saying that it replaces something rather than adding to it. The sheet on the clipboard already exists on most sites. It is just illegible, incomplete, and impossible to total up at the end of the month.

The wider point

A lot of utility contracting still runs on numbers that everyone treats as facts and everyone knows are estimates. Man hours is one of the clearest examples — quoted in cost reports, in client reviews and in safety statistics, and almost never measured. Counting it properly costs a crew ten seconds a day.
