On a high-rise build, every hour matters. Labour costs are rising, crane time is expensive, and programme pressure is relentless. Edge protection is often treated as a procurement afterthought, but the system you choose has a direct, measurable impact on your programme, your budget, and your bottom line.
The Real Cost of Edge Protection Is Not on the Invoice
When contractors and procurement teams compare edge protection systems, the conversation usually starts and ends with the day rate or the purchase price. That is the wrong place to start.
The true cost of an edge protection system is the sum of every hour it takes to install and move, every additional post that needs to be drilled and fixed, every repair that follows slab penetration, every COSHH control measure required for silica dust exposure, and every day of programme delay attributable to slow installation. On a complex, multi-storey build, those costs accumulate fast.
UK construction costs are under significant pressure. Labour costs rose by 7.1% year-on-year by mid-2025, and specialist trades are in short supply. With the CITB projecting a need for nearly 48,000 additional workers per year through to 2029, site teams are stretched and expensive. Any system that adds time to installation adds cost directly to the labour line.
Edge protection that installs faster, requires fewer components, and moves efficiently floor-to-floor is not a premium, it is a programme tool.
Installation Speed: Where the Time Is Won or Lost
On a high-rise concrete frame, edge protection must move upward with the build. Each floor cycle, typically five to seven days on a fast-track project, requires edge protection to be struck, moved, and reinstalled at the next level. On a 30-storey building, that means 30 installation cycles. The speed of each cycle matters.
Traditional drill-and-fix edge protection posts require a team to drill into the slab, insert chemical anchors or expansion fixings, torque to specification, and then repeat the process in reverse on removal, before making good the slab penetration. On a typical floor, this process is slow, creates silica dust exposure requiring COSHH controls, and leaves the slab requiring remedial repair.
Compression-based systems, which fix between the soffit and the slab above without drilling, eliminate every one of those steps. No drilling, no chemical anchors, no slab penetration, no dust, no remedial repairs. Installation is measured in seconds per post, not minutes.
The Rapid Post – Rapid-EPS’s flagship compression post – installs ten times faster than a conventional drill-and-fix post, and six times faster than any other compression post on the market. It requires no tools, no torque wrench, no specialist fixings, and leaves no mark on the slab. On a live programme, that speed differential translates directly to labour hours saved and floor cycles accelerated.
Fixing Centres: Why 2.7 Metres Matters
The fixing centre of an edge protection post, the maximum span between posts, directly affects how many posts are required on a given perimeter. More posts means more components to deliver, more to install, more to move, more to store, and more to return. On a large-footprint high-rise, the difference between a 2.4m and a 2.7m fixing centre can mean hundreds fewer posts across the life of the project.
The Rapid Post offers industry-leading fixing centres of up to 2.7m, the widest available anywhere in the market. All competing systems operate at 2.4m and under. That 300mm difference compounds across every floor, every perimeter run, and every cycle of the programme.
Fewer posts also means fewer deliveries, reduced crane picks, less site storage, and a simpler logistics operation. On a constrained city-centre site, where storage is limited and crane time is scarce and expensive, this is a meaningful operational advantage.
Silica Dust: The Hidden Cost of Drilling
Drilling into concrete generates respirable crystalline silica (RCS) dust, a serious occupational health hazard linked by the HSE to silicosis, lung cancer, and COPD. COSHH regulations require that silica dust exposure is controlled on construction sites, which means respiratory protective equipment (RPE), local exhaust ventilation (LEV), wet suppression methods, and documented risk assessments.
All of this takes time and costs money. It also adds administrative burden to site management teams and increases health monitoring obligations. For a large high-rise project with multiple floor cycles, the cumulative cost of managing silica dust from edge protection installation alone is not trivial.
A compression post system eliminates the need to drill entirely. No drilling means no silica dust from edge protection installation, which removes the associated COSHH obligations, reduces the RPE burden on operatives, and simplifies site management. That is a safety benefit and a cost saving.
Programme Delays: The Most Expensive Cost of All
Research from the CIOB and analysis by construction consultancies consistently identifies programme delays as one of the most significant financial risks on high-rise projects. On a typical multi-storey build, a single week of delay on a critical path activity can cascade into additional scaffold hire, extended crane contracts, extended prelims, and delayed occupation or handover, each of which carries a material cost.
Recent analysis by Elecosoft notes that on a project valued at £25 million running over two years, even modest delays can translate to hundreds of thousands of pounds in additional costs when all cascading effects are accounted for.
Edge protection is not typically the primary driver of programme delay, but it is one of the factors that can quietly absorb time on every floor cycle. A system that installs and strikes in a fraction of the time of an alternative does not just save a few hours. Across a 25-storey programme with weekly floor cycles, that efficiency compounds into days saved on the overall schedule.
Slab Repairs: A Cost That Is Rarely Budgeted
Drill-and-fix edge protection leaves anchor holes in the slab that must be made good before the floor can be finished. On a residential high-rise, where each floor will be handed over to fit-out contractors, those repairs must be carried out to a standard acceptable for screeding or other floor finishes.
The cost of slab repairs is often overlooked at the procurement stage. But across a 200-post installation on a single floor, with 30 floors to complete, the remedial work adds up, in materials, labour, and programme time.
Compression post systems leave no mark on the slab. There are no holes to repair, no delays to finishing trades, and no additional cost to the concrete frame contractor or the fit-out programme.
Product Lifespan: The Longest-Term Cost Factor
For hire companies and contractors who own their fleet, the lifespan of edge protection equipment is the single biggest determinant of its total cost of ownership. A system that lasts three to five years before it requires replacement will be purchased multiple times over the life of a business. A system that lasts 20 years or more, with proper maintenance, represents a fundamentally different capital commitment.
Rapid-EPS products are engineered for a 20+ year product lifespan, the longest in the industry. Competitors’ systems typically offer three to ten years before significant component replacement or system retirement is required. Over a 20-year period, the total cost of ownership of a premium, long-life system is significantly lower than a cheaper alternative bought multiple times.
This is not a marketing claim. It is an engineering decision, built into the specification of every component, from the coating systems used to resist site environment degradation to the structural design of connections that can withstand hundreds of hire cycles.
Putting It Together: What Does This Mean on a Real Project?
Consider a 25-storey concrete frame residential building. Edge protection must be installed and moved on every floor, 25 cycles over the course of the programme. Each cycle involves installing posts, hanging panels, moving the system to the next level, and striking and re-installing.
With a drill-and-fix system, each cycle involves drilling, anchoring, and on completion, making good every penetration. With a compression system operating at 2.7m fixing centres – reducing post count by approximately 11% compared to a 2.4m system – and installing at ten times the speed, the programme and labour savings over 25 cycles are material.
Projects like Karlatornet in Gothenburg (the tallest building in Scandinavia), Atlantis The Royal in Dubai, and One Blackfriars in London chose Rapid-EPS because programme performance and reliability at height are non-negotiable on builds of that complexity. The speed and certainty of the system is not incidental to the choice — it is central to it.
Key cost savings from engineered edge protection on a high-rise build:
- Labour savings from faster installation and strike – time saved per floor cycle compounds over the full programme
- Reduced post count through wider fixing centres – fewer deliveries, less crane time, less storage, simpler logistics
- Elimination of silica dust COSHH obligations – no drilling means no dust, no RPE costs, less site management burden
- Zero slab repair costs – compression posts leave no penetration to make good, removing a cost that is consistently underestimated at procurement
- Lower total cost of ownership for hire fleets – a 20+ year system replaces itself far less often than a 3–10 year alternative
The Decision Is Not About Price. It Is About Cost.
Edge protection procurement decisions made solely on day rate or purchase price systematically undervalue the operational impact of the system chosen. In an environment where UK construction labour costs are forecast to rise by a further 16% through to 2030, where crane time on major city-centre builds is constrained and expensive, and where programme delivery is increasingly scrutinised, the efficiency of every process on site matters.
A genuinely engineered edge protection system – one designed for speed, for durability, for wide fixing centres and tool-free installation – is not the most expensive decision on a high-rise build. It is one of the most cost-effective.
At Rapid-EPS, that principle is not a marketing position. It is the engineering brief behind every product we design.
