De-risking Projects - PCSA & Commercial Leadership
Supporting Safe, Compliant, and Sustainable Delivery Under the Building Safety Act
Daniel Jessimer, Commercial Director at Starfish Construction, joins us in this edition of our In-Focus series.

In today's construction landscape, few areas carry more weight than the pre-construction phase. With the introduction of the Building Safety Act and increasing regulatory oversight from the Building Safety Regulator, projects face unprecedented scrutiny at every stage. A structured Pre-Construction Services Agreement (PCSA), combined with robust commercial management, has become essential for de-risking projects across façades, roofing, and complete building envelope remediation, ensuring compliance and providing clients with cost and programme certainty before works even begin.

In this Starfish Construction Insight Q&A Interview, we speak with Daniel Jessimer, Commercial Director, about the essential role of PCSA and project commercial management.

Daniel explains how Starfish Construction supports clients with investigation, regulatory submissions, and cost assurance, while integrating its Principal Designer and Principal Contractor expertise to deliver clarity, compliance, and confidence from the very start of a project.
01

Daniel, let's start with the basics—what is a PCSA, and why is it so important today?


Daniel: A Pre-Construction Services Agreement (PCSA) sets the foundation for safe, efficient, and compliant project delivery. It allows clients to appoint a contractor before the main construction works begin, giving access to technical expertise, design validation, and cost planning.

In practice, this means we can thoroughly examine the design, conduct surveys, and plan logistics in detail before the project site kick-off. In today's Building Safety Act environment, early involvement isn't just practical; it's essential. It's the point where we identify project risks, prepare safety case documentation, and the project aligns with regulatory expectations.

02
How do PCSA and Gateway submissions connect, and what challenges do clients face with these requirements?

Daniel: The Building Safety Act introduced three Gateways for higher-risk buildings, each designed to stop projects progressing until project safety is evident in all phases. Gateway 1 involves planning, Gateway 2 requires approval before construction, and Gateway 3 confirms safe completion.

For Gateway 2, especially, submissions to the Building Safety Regulator can take approximately 25–40 weeks to assess. If your documentation isn't complete or compliant, delays are inevitable. That's where a well-managed Pre-Construction Services Agreement (PCSA) makes all the difference. By front-loading condition surveys, technical design, safety case preparation, and aligning the Golden Thread of information, we give our clients confidence that their Gateway submissions will withstand scrutiny and avoid costly rework.

03
What role does Starfish Construction play as Principal Designer and Principal Contractor in the PCSA stage?

Daniel: Acting as both Principal Designer (PD) and Principal Contractor (PC), we provide a seamless approach to safety and compliance. As PD, we design out risk wherever possible, coordinating input from architects, engineers, and fire consultants. As PC, we document and plan how we'll build safely, integrating sequencing, procurement, and logistics.

Combining these roles at the PCSA stage means duty holders get one integrated team, one Golden Thread of safety information, and one accountable partner. That clarity is invaluable when preparing Gateway submissions and demonstrating compliance.

How does commercial management during PCSA support cost certainty and programme clarity for clients?


Daniel: Commercial leadership in the PCSA phase is about turning uncertainty into clarity. We validate design proposals against real-world buildability, provide accurate cost forecasting, and develop procurement strategies that reflect the market.

One of the most significant risks we often encounter is procurement, particularly with specialist cladding, roofing, and fire-rated systems, where lead times extend without proper procurement management. Without early engagement, this can cause severe programme delays. That's why, as part of the PCSA process, we engage our procurement teams in the planning. We establish honest and transparent relationships with our supply chain partners early, validate material availability, and ensure the secure supply of compliant products in line with Gateway requirements.

By doing this, we protect our clients from supply chain shocks, avoid last-minute substitutions, and ensure that procurement strategies are realistic, transparent, and aligned with budgets and programme delivery. The result is cost certainty, programme confidence, and compliance assurance—three things every duty holder needs under today's regulatory and financial pressures.

05

What risks do clients face if they don't fully invest in the PCSA stage?


Daniel: The risks are significant. Without a structured PCSA, projects often suffer from incomplete design, underestimated budgets, and insufficient risk assessment. That can lead to rework, disputes, and worst of all, non-compliance with the Building Safety Act.

For higher-risk buildings, you cannot bypass Gateway requirements. If your submission isn't comprehensive, you face delays of months or even years. Investing in a thorough PCSA isn't an added cost—it's the best insurance policy a project can have.

How does sustainability and ESG integration fit into PCSA and project commercial management?

Daniel: We embed sustainability measures from the outset. In the PCSA stage, we advise on materials with low embodied carbon, plan insulation and energy efficiency measures, and build waste reduction into logistics. We also ensure projects align with our and our clients' ESG goals and future-proof assets for regulatory changes.

Making these decisions early, rather than bolting them on later, saves costs and delivers real long-term value for both the building owner and the communities interacting with properties, including residential blocks, public buildings, and mixed-use developments.

07

Finally, what advice would you give to building owners and duty holders navigating PCSA, Gateways, and commercial management?


Daniel: My advice is simple: act early, and act with competence. Engage with experienced partners who understand not only the technical and commercial aspects, but also the regulatory landscape. We've managed and supported clients on some of the most complex and challenging building remediation projects in the UK.

Don't wait for Gateway deadlines to loom. Prepare your safety case, cost plan, and procurement strategy upfront. By doing so, you'll not only de-risk your project but also create a smoother, faster path to safe and compliant delivery.
