Hiring for construction

Nobody should hire a bricklayer through a web form, and this page does not suggest it. The office is a different story.

Construction trade competence is established through certification schemes, practical assessment and on-site verification, none of which a remote skills test replaces. Verified assessment applies to the professional and supervisory layer: estimating, quantity surveying, planning, project and site management, design coordination and health and safety roles, where judgement, numeracy and regulatory knowledge determine whether a project runs to time and cost.

The short version

  • Trade cards and practical competence are verified through the relevant scheme, after reveal, and are never scored.
  • The professional layer is where the money is lost and won, and it is usually hired on reputation and referral.
  • Estimating and quantity surveying are among the most assessable roles in any sector, and among the least assessed.
  • Safety knowledge is testable and consequential, which is an unusual combination worth using.

Where a project actually goes wrong

The trades on a site are usually competent. Certification schemes, apprenticeships and the simple visibility of the work mean that someone who cannot do the job is identified quickly. Trade hiring has problems, mostly around availability and subcontracting, but competence verification is not the main one.

Projects go wrong in the office. Almost always. A mispriced tender, a programme that never had float in it, a design coordination gap discovered on site, a variation nobody documented. Each of those traces back to a professional appointment, and professional appointments in this industry are made overwhelmingly on the basis of who someone worked for and who vouched for them.

That is not irrational. A referral from someone whose judgement you trust is real information. It is also a closed loop. It is also a closed loop, which is why the professional layer of construction remains among the least diverse parts of the built environment and why the same firms keep hiring from the same small pool.

Roles where assessment is genuinely predictive

  • Estimating and quantity surveying

    Take-off accuracy, rate build-up, spotting what a drawing does not show. Directly testable, directly consequential, and the difference between candidates is enormous.

  • Planning and programme

    Sequencing, float, and understanding which dependency is the one that will actually bite. A scenario test surfaces this in an hour; a CV never does.

  • Health and safety

    Applying regulation to a site condition, and knowing when to stop work. Knowledge alone is insufficient and knowledge plus judgement is what you are hiring.

  • Site and project management

    Prioritising when three trades want the same area on the same morning. Every site manager has an opinion about this and their reasoning varies far more than their CV suggests.

  • Contract administration

    Notices, variations and the discipline to document at the time rather than afterwards. Expensive when it is missing and rarely probed at interview.

  • Design coordination and BIM

    Clash detection and information management. A technical role assessed like any other technical role.

Where this does not belong

Trade competence is not assessed here. Bricklaying, steel fixing, plant operation and every other on-tools skill are proven through certification schemes and practical assessment on site. A remote test would be worse than useless because it would produce a number that looks like evidence.

Site safety cards and equipment certifications are hard requirements verified through the appropriate scheme after reveal, never scored and never traded against anything.

Subcontractor and labour-only hiring runs on availability and day rate against an immediate need. An assessment step does not fit that model and should not be forced into it.

Construction is a strongly relationship-driven industry, and a firm that adopts anonymous screening for professional roles will find it culturally uncomfortable before it finds it useful. That is a real adoption cost and worth planning for rather than discovering.

Questions people actually ask

Can you assess trade skills?
No. Trade competence is established through certification schemes and practical assessment on site. Nothing on this platform substitutes for either, and we would not want it to.
How are safety cards and certifications handled?
As hard requirements verified through the relevant scheme after a consented reveal. They are legal and contractual facts rather than scored attributes.
Which construction roles benefit most?
Estimating, quantity surveying, planning, project and site management, contract administration, design coordination and health and safety. The professional layer, where judgement determines project outcome.
Will this work for a firm that hires mostly through referrals?
It works alongside them. Referred candidates take the same assessment, which gives you the referral’s information plus something comparable. Firms that find this uncomfortable usually find it useful about two hires in.
Does this help with the industry’s diversity problem?
Partly, and only at the professional layer. Anonymous screening removes one filter in a system with several. It does nothing about who enters the industry, which is where the larger constraint sits.

Where this connects to the rest of the platform.

  • Work-sample assessments

    A realistic, bounded task for roles where a knowledge test is not enough. Scored against a rubric written before anyone attempts it.

  • Hiring for logistics and supply chain

    Licences and certifications are gates, not scores. Assessment belongs to planning, coordination and the supervisory layer, where judgement under pressure is the whole job.

  • Hiring for technology and software teams

    The sector where application volume exploded and the resume stopped carrying signal first. Verified assessment is the only screen that still separates candidates.
