The PEB Manpower Gap: When Order Books Grow Faster Than Teams

The enquiry arrives on a Tuesday. A 9,000 MT warehouse, drawings needed in six weeks, and the client has already told you which month they want the first frames on site. Your plant can roll it. Your commercial team can price it. Then someone asks the question that decides whether you bid at all: who is going to detail it?

This is now the most common constraint in Indian pre-engineered building (PEB) work. Not steel, not press brakes, not paint lines. People who can turn a design into a correct, fabricable model and a drawing set the shop can build from. This post is about sizing that gap honestly and closing it, written for promoters, plant heads and detailing managers who are being asked to grow faster than their teams can absorb.

The gap is arithmetic, not opinion

Look at what the listed players are doing with capacity. Interarch reported FY26 revenue of about ₹1,898 crore, up 30.6% year on year, with an order book of roughly ₹1,703 crore at the end of April 2026, and it has taken total manufacturing capacity to 221,000 MT a year with further plants in Andhra Pradesh and Gujarat heading for commissioning (ICICI Direct, Business Upturn). EPACK has moved into data-centre structures through a dedicated subsidiary, arguing that speed to market is now the deciding factor in that segment (EPACK Prefab). Market researchers put the Indian PEB market in the region of USD 2.3 billion and growing at double digits (IMARC Group).

Treat those market figures with the caution any commissioned forecast deserves. The part you can verify yourself is simpler: tonnage capacity across the industry is being added in blocks of tens of thousands of tonnes a year, and nobody announces a matching expansion of their drawing office.

The wider labour picture says the same thing. The Project Management Institute's Construction Project Management Talent Gap Report 2026 estimates India will need close to 395,000 construction project professionals by 2035, with the South Asian gap widening from 291,000 to as much as 558,000 people. The same reporting notes that 72% of projects exceed budget, 73% run late and 70% suffer scope creep, and that many engineering graduates arrive "without sufficient exposure to practical project environments" (Outlook India).

That last phrase is the one that costs PEB companies money. The shortage is not of graduates. It is of graduates who can work.

Find your own ratio before you plan anything

Most firms cannot answer a basic question: how much tonnage does one detailer actually deliver in a month, in your office, on your kind of buildings?

Work it out from your last four completed projects.

1. Take the tonnage of each project, and the detailing hours booked against it, including checking and revisions.
2. Convert to detailer-months at your real working hours.
3. Divide tonnage by detailer-months. Do it separately for straightforward warehouses and for complex jobs: mezzanines, crane buildings, heavy bracing, odd geometry, fussy client standards.

You will usually find two very different numbers, and a third for anything involving a new client's standards. That spread is your planning tool. Multiply next year's expected mix by those rates and you have the size of bench you need, not the size you hope to get away with.

Two corrections make the number honest. First, subtract the capacity your senior people lose to checking: a checker reviewing juniors is not also detailing. Second, add the revision load that actually occurred, not the one in the estimate.

Why the bench is always short

Detailing is the narrowest skill in the chain. A fabricator can hire a welder from another industry. A detailer needs structural understanding, software fluency, drawing discipline and shop knowledge at the same time, and the combination takes months to build.

Experienced detailers are already employed. In a growing market, the only way to hire one quickly is to pay above the market and take them from a competitor, who will then do the same to you. Salary escalation spreads and nobody's bench gets bigger.

The work arrives in bursts. Order intake is lumpy. Detailing demand peaks immediately after award, then falls away while the shop and site catch up. A team sized for the peak is idle later; a team sized for the average is the reason drawings are late.

Attrition hits at eighteen months. That is roughly when a trained fresher becomes independently productive and therefore valuable to everyone else. Firms that treat training as a cost lose exactly the people whose training has just paid off.

Three ways to close it, with real costs

Hire experienced detailers

Use when: you need capacity this quarter and the work is complex.

Real cost: a salary premium over your existing band, a notice period you cannot compress, and the internal effect on people already on your payroll doing the same job for less. Expect four to eight weeks to first useful output even from a good hire, because your standards, templates and client preferences are not theirs.

Limit: it does not create capacity in the industry. It moves it, at a higher price, and the same person can be moved again.

Train freshers into the role

Use when: your demand is structural rather than a single project spike, and you can protect three to four months of ramp-up.

Real cost: training fees or trainer time, licences, and supervised months where output is low and checking load is high. The honest part of this option is that the first project a trained fresher touches will consume senior attention.

Payoff: it is the only route that adds net capacity, it costs less per head over two years than repeated lateral hiring, and it gives you people who learned your standards first. It works when the training is on real project workflows: modelling, connections, numbering, GA and fabrication drawings, bills of material, and NC output. Tekla's own documentation makes the point that settings such as pop-marks and contour marks must be fixed before numbering and drawing creation, because both affect numbering. That is the level of process discipline a new detailer has to arrive with, and it is learned on projects, not slides.

Outsource to a detailing partner

Use when: you need to absorb a peak without permanent headcount, or you want to keep a plant loaded while your own team handles the complex work.

Real cost: a rate per tonne or per hour that looks high next to a junior salary and is often correct once you count supervision. Add your own checking time, which does not disappear; it usually increases for the first two projects while the partner learns your standards.

Limit: you do not build institutional knowledge. If the partner's team changes, you start again. Keep the standards, the templates and the checking in-house whatever else you outsource.

Most firms that get through a growth phase intact use all three: a small permanent core they trained themselves, one or two senior lateral hires for complexity, and a vetted partner for overflow.

A 90-day plan for a bench you can defend

Days 1–15. Calculate your tonnage-per-detailer ratios. Publish the number. Map the next four quarters of expected award against it and mark the months where you are short.

Days 16–30. Decide the mix. Write down how many heads come from training, from lateral hiring and from outsourcing, and what each is allowed to cost. Name the person who owns each channel.

Days 31–60. Start the training intake and the partner qualification in parallel, because both have lead times and neither is reversible in a hurry. For the trained intake, agree which live project they join and who checks their work.

Days 61–90. Put the retention structure in place before the first trained batch becomes valuable, not after. That means a visible path from detailer to checker to lead, a review at month twelve rather than month twenty-four, and a reason for a good detailer to stay that is not only salary.

Keeping the people you train

The cheapest capacity you will ever have is the detailer you trained who is still with you in year three. Four things decide whether that happens, and only one is money.

• A named next role. People leave when the job looks like the same drawing for ever. A checker or lead path, written down, changes the conversation.
• Checking as training, not punishment. Offices where juniors are taught to check their own work produce independent detailers faster, and the juniors know they are being invested in.
• Certification that travels. Engineers value credentials they can carry. Paying for a certification and keeping the person is still cheaper than replacing them.
• Variety. Two years of identical warehouses is a resignation letter waiting to be written. Rotate complexity deliberately.

What to measure

Track four numbers monthly and you will see the gap before it becomes a delay:

• Tonnage detailed per detailer-month, by project complexity
• Backlog in detailer-months against confirmed and likely orders
• Percentage of checker time spent on rework rather than first-pass checking
• Attrition at the twelve-to-twenty-four month band, separately from overall attrition

The fourth is the one most firms never isolate, and it is the one that tells you whether your training investment is building a bench or a supply line for your competitors.

Where STEEL fits

STEEL is a Tekla Authorized Training Centre running a 12-week classroom program in PEB steel detailing and Tekla Structures, weighted 70% practical, ending with a complete PEB project. If you are closing the gap by training, we run corporate and enterprise batches for teams and new hires. If you are closing it by hiring people who have already done the work, you can share a hiring requirement and receive profiles of candidates who have detailed a full building, not just finished a course.
