Three tenders land in the same fortnight. Your estimator is already flat out on one, the second has a return date you can't move, and the third is the job you actually want. So you turn one down, rush all three, or find help. Outsourced estimating services exist for exactly this: an external team that measures and prices work for you, so your tender list isn't capped by how many people you've got sat at desks.
The option most main contractors think of first is hiring another estimator. Sometimes that's right. Often it isn't.
Tenders don't arrive evenly, and neither does the workload
Tender work comes in waves. A quiet month, then four invitations at once, half of them with drawings that turn up late. An in-house team sized for the busy weeks sits partly idle in the quiet ones. A team sized for the quiet weeks can't cope when it gets busy, so something gives: pricing gets rushed, packages go out to subbies without a proper measure, or you decline tenders you'd have liked to win.
That's a capacity problem, not a skills problem. And capacity is the thing outsourcing fixes best.
We've written before about the estimating job nobody on the team has time to do properly. For a main contractor it's usually the measure: the slow, detailed takeoff that everything else depends on.
Hiring an in-house estimator vs outsourced estimating services
An in-house estimator is a salary plus employer costs, software licences, a desk and management time. It's a fixed cost you carry whether there are ten tenders this month or none. You also get one person's capacity and one person's holidays. If they leave in the middle of a busy spell, you're back to square one.
There's also the time it takes to recruit. Finding a good estimator isn't quick, and the tender peak you're hiring for may well be over before they start. Then there's fit: someone used to commercial fit-out won't necessarily price a housing scheme the way you would.
What you get in return is someone who knows your business, your supply chain and the way you like a price presented. That's worth a lot. For a contractor with steady, high tender volume it can be the right call.
Outsourcing works differently. You pay per job, when you need it, and the cost follows the workload instead of sitting on the payroll. You're drawing on a team rather than an individual, so a tender peak doesn't have to become a bottleneck.
Plenty of contractors do both. A small in-house team owns the bid, adjudicates subcontract quotes and makes the commercial calls, while the heavy measurement and first-pass pricing are sent out. That split tends to work because it keeps the judgement inside the business and moves the hours outside it.
If you're weighing up a single freelancer against a firm, our post on a freelance construction estimator versus an estimating service covers the practical differences.
What a remote estimating department actually does
Think of it as a remote estimating department you can switch on per tender. You send the drawings and tender documents. The team measures every element to NRM2, prices it on current UK rates local to the job, and returns a breakdown you can review, adjust and submit under your own name.
What you should expect back
- Measured quantities for each element, traceable to the drawings.
- Rates that reflect the market now in that part of the country, not a national average from years ago.
- A breakdown clear enough to pull sections out and send to subcontractors for their packages.
- Assumptions and exclusions written down, so you know where the risk sits before you submit.
What you keep is the decision. The outsourced team gives you a properly built cost. The margin, the risk allowance and whether to bid at all stay with you, because your company is the one signing the form of tender.
Because the measure is done to NRM2, anyone on your team can pick it up and follow it. That helps when the bid manager, the contracts manager and a director all want to look at the same figures before sign-off.
When it makes sense to outsource construction estimating
It isn't right for every contractor or every job. It tends to pay off when:
- tender volume swings month to month and another full-time salary is hard to justify;
- you're bidding outside your usual region and need rates that reflect local labour and materials;
- your own estimator should be spending time on adjudication and client meetings rather than measuring;
- you've been declining tenders purely for lack of time.
It's less useful when the information is very thin and the job needs weeks of back-and-forth with the design team before anything can be measured. Outsourcing can still help there, but you'll need to stay closer to the process.
The question to ask yourself is simple. Are you losing work, or losing margin, because nobody had time to price it properly? If the answer is yes, it's worth looking at how outsourced estimating services for main contractors would sit alongside your own team.
Making outsourced tender pricing work day to day
Most of the friction comes from the handover, not the pricing. A few habits help.
Send everything at once: drawings, specification, tender instructions and the return date. A document that turns up halfway through is where time gets lost. Say which packages you'll price yourself or already have subcontract quotes for, so nobody measures the same work twice. And agree the fee before anything starts. With MPE that's a fixed fee, set once we've seen the drawings, so there's no hourly meter running in the background.
Then review what comes back the way you'd review your own estimator's work. Check a few quantities against the drawings. Read the assumptions. If something looks off, ask. A good estimate should be easy to question, because every figure came from somewhere you can point at. (Our post on a tender price that survives being read by someone else makes a decent checklist for that review.)
Done properly, outsourced estimating becomes part of how you tender rather than an emergency measure. You bid for the jobs you want, not just the ones you had time for.
