By Martin Leekblade, Pre-Construction Director
In the competitive world of façade remediation, cost scrutiny is intense. That is entirely understandable. Many projects arise from urgent building safety concerns. Budgets are under pressure. Stakeholders are expected to demonstrate value at every stage.
However, we continue to see procurement decisions influenced by one recurring issue: an over-reliance on low preliminaries as a measure of contractor value.
What Are Prelims and Why Do They Matter?
Preliminaries, commonly referred to as prelims, are the essential resources required to establish and manage a construction site. They include access arrangements, welfare facilities, supervision, temporary works, health and safety management, logistics coordination, programme planning and quality assurance oversight.
They are not part of the façade system itself. But they determine how safely, efficiently and compliantly that façade can be delivered.
In façade remediation, prelims are not secondary costs. They are fundamental to project control.
The Illusion of Cost Savings
At Regency Facades, we regularly review remediation tenders that present minimal site prelim allowances in order to make the overall package appear commercially attractive.
What is often missing are realistic allowances for:
- Resident liaison and communication
- Complex access sequencing
- Temporary works design and coordination
- Welfare and safety management
- Quality assurance and compliance monitoring
- Detailed programme management
These omissions may not be obvious at award stage. However, they tend to surface quickly once mobilisation begins.
Cheap prelims rarely translate into genuine lifecycle savings. Instead, they introduce risk, uncertainty and avoidable disruption.
Why Remediation Projects Are Different
Façade remediation is not comparable to straightforward new build delivery.
Projects are frequently carried out in occupied buildings. They involve legacy design constraints, evolving fire safety requirements, strict compliance oversight and safety-critical sequencing. The early stages of a remediation programme are particularly sensitive.
Under-resourced prelims limit a contractor’s ability to plan thoroughly, adapt to unforeseen issues and maintain control under pressure. In live environments, that lack of structure can quickly affect programme certainty and stakeholder confidence.
What Well-Structured Prelims Look Like
Well-considered prelims reflect a clear and responsible delivery strategy.
They account for the realities of the site, the nature of the works and the obligations introduced by the Building Safety Act. They support:
- Smoother mobilisation
- Clearer communication with residents and stakeholders
- Robust supervision and site management
- Stronger programme resilience
- Transparent compliance processes
In short, they demonstrate how a contractor intends to operate, not just what they intend to install.
A Procurement Lens, Not a Line Item
Prelims should not be viewed as a secondary cost line. They should be treated as insight into delivery capability.
Procurement teams should be asking:
- What assumptions have been made?
- What has been deliberately included or excluded?
- Has access and sequencing been accurately costed?
- Are safety and resident liaison adequately resourced?
- Is there sufficient allowance for coordination, monitoring and compliance?
The answers to these questions are rarely visible from a number alone.
The Bigger Risk
Cheap prelims may help win tenders. But they often compromise control once work begins.
In the façade remediation sector, the consequences of delivery failure are significant. Safety, compliance, programme certainty and public confidence are all at stake. Early commercial decisions influence behaviour on site, and prelims are among the earliest decisions made.
When structured properly, they reduce downstream costs, strengthen delivery confidence and improve safety outcomes across the project lifecycle.
Clients should not be persuaded by headline figures alone. They should look closely at what sits behind them.
