How poor communication kills more projects than poor workmanship

In construction, failure is often blamed on workmanship. When something goes wrong on site - a defect, a delay, a cost overrun - the immediate instinct is to look at the quality of the work itself, but in reality, poor workmanship is rarely the root cause. More often than not, the real issue is far less visible and far more systemic - it is poor communication, writes John Ridgeway.

Across the construction industry, projects do not typically fail because people cannot build. They fail because people are not aligned - on scope, on expectations, on timing or on responsibility. And when communication breaks down, even the most skilled teams can deliver poor outcomes.

The scale of the issue is well documented. According to a report by Project Management Institute (PMI), ineffective communication is a primary contributor to project failure in nearly one-third of projects, with organisations losing millions each year as a result.

In construction specifically, the challenge is amplified. A study by Autodesk and FMI found that poor communication and data management were responsible for a significant proportion of rework in the industry, contributing to billions in avoidable costs globally. This is a critical point. Rework - often attributed to poor workmanship - is frequently the result of unclear or miscommunicated information.

Where communication breaks down

Construction projects are inherently complex. They involve multiple stakeholders, including clients, consultants, contractors, subcontractors and suppliers. Each has their own priorities, timelines and responsibilities. In this environment, communication is not just important - it is fundamental - yet breakdowns occur at every stage.

At the design phase, information may be incomplete, unclear or subject to change. Drawings may not fully reflect buildability, or key details may be missing altogether. During procurement, scope can be misunderstood or poorly defined, leading to assumptions that later result in disputes.

On site, communication becomes even more critical. Instructions may be passed verbally, but details may be interpreted differently and changes may not be fully understood by all parties. By the time issues emerge, they are often embedded in the work itself.

One of the most damaging aspects of poor communication is that its impact is rarely immediate. A misunderstood detail might not become apparent until weeks later. A missing piece of information might only surface during installation. A change in specification might not reach the right person at the right time. When these issues eventually come to light, the consequences can be significant.

Work may need to be removed and redone. Programmes may be delayed. Costs increase. Relationships come under strain.

According to the Construction Industry Institute, rework can account for up to 5% of total project costs, much of which is linked to errors in communication and information flow. This is not a workmanship issue. It is a coordination issue.

The myth of the “Bad Contractor”

When projects go wrong, blame is often directed at those delivering the work. But this overlooks a key reality. Contractors build what they are instructed to build. If information is unclear, inconsistent or incorrect, even the most competent teams will struggle to deliver the right outcome.

The Chartered Institute of Building (CIOB) has highlighted that many project issues stem from poor coordination and communication between stakeholders, rather than a lack of technical ability. This is not to say workmanship does not matter. It does. But it is rarely the primary cause of failure.

At its core, communication in construction is about people. Projects are delivered by teams, often under pressure, working to tight deadlines and complex programmes. In these conditions, communication can easily become rushed, informal or assumed.

Phrases like “it should be obvious” or “that’s how we always do it” are common on site. But assumptions are where problems begin. The Health and Safety Executive (HSE) has long emphasised that clear communication is critical to both safety and performance, noting that misunderstandings can lead not only to errors, but also to increased risk. In other words, communication is not just about efficiency - it is about control.

In recent years, the industry has invested heavily in digital tools designed to improve communication. Common Data Environments (CDEs), project management platforms and real-time reporting systems have all been introduced to streamline information flow.

These tools are valuable, but they are not a solution in themselves. Technology can facilitate communication, but it cannot replace it. If information is unclear at source, digitising it does not make it clearer. If teams are not aligned, no platform can resolve that. The issue is not a lack of tools. It is a lack of clarity.

What good communication looks like

If poor communication is the problem, what does good communication look like in practice? It starts with clarity. Information should be complete, consistent and accessible. Drawings should be buildable. Specifications should be unambiguous. Changes should be clearly communicated and documented. It also requires accountability.

Everyone on a project should understand their role, their responsibilities and how they connect with others. This reduces reliance on assumptions and ensures that decisions are made with the right context. Perhaps most importantly, it requires a culture of openness. Teams need to feel able to ask questions, challenge information and raise issues early. Problems identified early are far easier to resolve than those discovered later.

For the construction industry, addressing communication issues requires a change in mindset. Instead of focusing solely on output - what is being built - there needs to be greater focus on input and how information is shared, understood and acted upon.

This means recognising that:

• Communication is a process, not an afterthought
• Clarity is more important than speed
• Alignment is more important than assumption

It also means moving away from a blame culture. When issues arise, the question should not be “who got it wrong?” but “where did communication break down?”

This is because construction is a highly skilled industry. The ability to build is not the problem. The challenge lies in ensuring that everyone involved in a project is working from the same understanding, at the same time, with the same information. Because when communication fails, even the best workmanship cannot compensate.

Projects do not fail because people cannot do the work. They fail because people are not told - clearly, consistently and at the right time - what needs to be done. And until that is addressed, poor communication will continue to undermine more projects than poor workmanship ever could.
