In his most recent column for Demolition Hub, RVA’s MD Richard Vann looks at when it’s right to say no to a demolition assignment. If you missed the article, catch up below, or read it in full here on page 96.

No matter how extensive your demolition planning techniques, you never truly know what’s around the corner. And with multiple variables at play, it’s impossible to control one single, specific route map. It would be naive to think this is the case. But that doesn’t mean you can’t be prepared for different outcomes.

As part of a regular feature for Demolition Hub, Richard Vann recently imparted must-know insight on this very topic. Here, he explores why scenario planning is crucial when managing large-scale demolition projects – providing the knowledge and agility to react when the unexpected happens, while keeping safety, costs, and timelines at the forefront.

Taking control of uncertainties

Demolition is a complex, often unpredictable process – one that involves far more than simply knocking down structures. Unlike construction, where precise plans are drawn up from blueprints and materials, demolition projects are full of unknowns. From structural complexities and outdated designs to hazardous substances that pose risks to human health, many of these may only become apparent once the work begins.

This is why feasibility and option studies are such powerful tools in our industry. They allow us to consider the different paths a project might take, each with its own variables and potential challenges, to anticipate different outcomes and create contingencies for each path. From the exploration of different asset divestment options and methodologies to resource planning and EHS considerations, this type of scenario planning empowers clients with intel, supported by evidence-based recommendations, to make informed decisions at every stage. 

Such studies are even more value-adding when accompanied by live, adjustable spreadsheets that adapt financial projects as external factors evolve. With a more dynamic approach, teams can confidently navigate any disruption without losing sight of the project’s end goal.

Flexibility in execution

Even with a comprehensive schedule of work in place, backed by a proficient project team equipped to execute the methodologies agreed, a plan should always remain flexible. Here’s why:

Every project holds surprises

Demolition projects, by their very nature, uncover unanticipated challenges all the time. And as the saying goes – you don’t know what you don’t know. So how can you plan for everything? And why would you execute every planning exercise in utmost detail if you aren’t yet clear on exactly what the detail will be?

Demolition doesn’t follow a blueprint

If you build a house, a quantity surveyor can use a design to calculate the quantity and type of materials required, as well as a project timeline, with a significant degree of accuracy. Even with this blank slate, unexpected challenges may arise along the way – so imagine the complexities when dealing with decades-old infrastructure where documentation is incomplete, inaccurate, or often nonexistent.

Complexity magnifies uncertainty

Deconstructing an asset the size of a power station, which has stood for more than 60 years, brings a whole new level of complexity. Drawings are often incomplete – if not missing altogether – and the people who operated the plant may no longer be available to provide site-specific knowledge. Educated assumptions must therefore be made until surveys can be concluded and the structure is brought to a known state. 

Planning is a living process

Structures and scenarios constantly change, so planning must remain dynamic at every stage of the demolition, adapting to developments as they arise. Planning only stops when the asset has been brought safely to the ground and prepared for its next phase, whether it’s repurposed or mothballed for future use.

Mindset is as critical as the plan

Mindset matters almost as much as the quality of the initial plan itself. You can’t take your eye off the ball, as you don’t know what tomorrow will bring. And the ongoing progress and evolution of the plan should not – and cannot – remain the responsibility of just one party.

Collaboration reduces risk

At RVA Group, we’ve long talked about the importance of a tripartite alliance between a client, contractor, and an independent consultant like RVA. For a start, nobody knows everything. A contractor may be able to prove the capabilities of a new machine that could help complete the project quicker and safer, for instance. Or there may be advanced waste management experience that would strengthen the environmental credentials of a methodology.

Failing to include all three parties at the decision-making table increases project risk. In one instance, a client engaged RVA to draft a job specification, before terminating our involvement when the contractor was appointed. The client took the programme forward without ongoing impartial project management support, and there were two major incidents on site. 

Assumptions can undermine success

Some operators bypass independent advice altogether, relying on presumptions instead of evidence. But without detailed surveys, for instance, how can a contractor provide accurate quotes? Does the client understand the supply chain’s capacity or anticipate programme delays? Have isolation strategies been designed to ensure the safety of all stakeholders? And what about resale opportunities for dismantled assets versus the scrap market? The planning considerations, of course, go on and on, but comprehensive planning answers a myriad of questions like these.

Prepare now or pay later

To organisations rationalising their operations or mothballing a redundant site to limit their liability, demolition may seem like a straightforward task. A nuisance event to move past quickly. But this mindset invites trouble. Cutting corners in planning means you’re gambling on what lies ahead – and it’s better to prepare for the unexpected than to pay the price later.
