A construction planner develops and owns the programme that gets a build delivered on time and on budget, managing the critical path, sequencing the works and resource-loading labour and plant across the whole life cycle of a project. Getting that hire right is one of the highest-leverage decisions you will make, because the wrong planner sends ripple effects through your site teams, procurement and subcontractor interfaces long before anyone notices the programme is slipping.
On building and housing projects the planner is the central coordinator between design, procurement, delivery and the client. They write and maintain the programme, run lookaheads, manage the critical path, resource-level labour and plant, and advise on constraints and mitigation.
The best planners are communicators as much as technicians. They drive delivery meetings, challenge procurement lead times, and anticipate clashes with other trades and client milestones before those clashes reach site.
A planner who can only produce a Gantt chart is a scheduler. A planner who can protect your programme is the person you actually want to hire.
Technical ability is non-negotiable, and it is easy to overstate on a CV, so look past job titles and probe for specifics.
In the UK the tools that matter most are:
Whichever tool a candidate names, ask what they actually did in it rather than accepting the logo on the page.
Strong planners pair that software fluency with genuine commercial awareness: float negotiation, the basics of delay analysis, change control, and an understanding of how NEC or JCT contracts treat time-impact assessments. Exposure to BIM and 4D sequencing is increasingly valuable, as is enough Excel and Power Query skill to clean data and build resource histograms quickly.
Finally, confirm the practicalities of site access. A CSCS card is expected for regular site attendance, a PTS card is mandatory on rail projects, civils and heavy-lifting work brings its own plant and access considerations, and mechanical and electrical programmes bring confined-space rules of their own.
A capable planner arrives with a clear way of working rather than waiting to be told how to plan.
Expect discipline-led weekly or fortnightly lookaheads that surface constrained activities and procurement needs, forward and backward resource levelling that avoids spikes in labour and plant, and genuine critical-path analysis that identifies true float, near-critical chains and contingency actions on long-lead items.
Good planners also run rolling 13-week lookaheads linked back to the baseline rather than free-floating sequences. And they treat programme change control seriously, with issued-for-construction dates, change logs and time-impact registers that keep everyone honest as the job evolves.
Assertions in an interview mean little, so build two or three short, focused exercises into your process:
A sharp brief attracts sharper candidates. Picture a building and housing planner in the South West on a permanent or six-to-twelve-month contract, reporting to the Head of Construction or the project manager.
The core responsibilities are to maintain the baseline programme and issue weekly lookaheads, own the critical path and resource histograms, produce procurement milestone lists that protect long-lead items, and run weekly delivery meetings with recorded actions.
The most revealing questions ask for lived experience, not theory. A few worth asking, and what a good answer sounds like:
The right route depends on how quickly you need cover and how long you need it.
Verify recent short-term programme fixes, set a rapid assessment task and confirm immediate availability and notice period. Speed is the whole point of an interim hire, so references that confirm hands-on delivery matter more than long-term potential.
Weigh cultural fit, longer-term programme ownership and development ambitions such as NVQ progression or chartered planner aspirations. In both cases, check site-access tickets and card status and look for recent employer references that confirm hands-on delivery rather than desk-bound reporting.
A few honest metrics tell you whether a hire is protecting the job:
A few patterns are worth pausing on before you shortlist:
We recruit planning professionals across building, civils, mechanical and electrical, and rail projects throughout the South West and the wider UK. Our vetting includes practical tool tests and programme exercises, so you see real outputs rather than claims on a CV, and we verify site-access cards and references before anyone reaches your shortlist. For interim cover we can usually present candidates within 48 to 72 hours, while permanent searches typically take four to eight weeks depending on notice periods and sector experience.
See how we support employers or get in touch to discuss your planner vacancy.
A construction planner develops and maintains the project programme, manages the critical path, sequences the works and resource-loads labour and plant to keep a build on time and on budget across its full life cycle.
Look for fluency in Asta Powerproject, Primavera P6 or Microsoft Project, advanced Excel, and an understanding of NEC or JCT contract time provisions, backed by a CSCS card for site access and three or more years of relevant planning experience.
Choose interim or freelance cover when you need programme support fast or for a fixed stage, and a permanent hire when you want long-term ownership and cultural fit. Harbron can advise on the right mix for your project.
For interim cover we can usually present suitable candidates within 48 to 72 hours. Permanent recruitment typically takes four to eight weeks, depending on notice periods and the sector experience required.
If the planner will attend site regularly, a CSCS or equivalent access card is required, and a valid PTS card is mandatory for rail projects. We check and record card status during vetting.
