The Contractor justifies cost spent, and the Project Manager assesses the evidence offered Ask ten commercial teams who must prove that a cost qualifies as Defined Cost under NEC4, and you will hear several answers. Too many contractors submit an application, then wait for the client’s cost assurers to decide whether the data is good enough. That sequence inverts the contract. Project Managers assess the Price for Work Done to Date. Contractors supply the evidence that suppor

Most suppliers can contribute far more than their clients ever ask of them.​‌​‌​​​‌​‍​⁠​​‌⁠‌⁠‌​‌‌‌⁠‌‍​‌​​⁠‍ The ideas are in the asset, on the site and in the design office. They just rarely reach the client. That is seldom a capability problem. It is a context problem: the procurement, the contract and the client’s own behaviour tell suppliers what is safe to say and what is worth the effort.​‌​‌​​​‌​‍​⁠​​‌⁠‌⁠‌​‌‌‌⁠‌‍​‌​​⁠‍ PAS 4010 changes that context by asking the client

Can your leadership state, in one sentence, why your organisation wants higher productivity? Most infrastructure clients ask the same question when productivity stalls:​‌​‌​​​‌​‍​⁠‌‍⁠‌​‌⁠​​‍‍​‍‌​⁠⁠‍​‍ what is the supply chain getting wrong? It is usually the wrong place to start. Contractors, designers and suppliers respond to the signals they receive. They price what the client asks for and pace themselves to the client’s decisions.

Consider the moment an enhancement transfers into service and the operations team registers nothing unusual, because the new asset behaves precisely as the network expected.​‌​‌​​​‌​‍​⁠‍‍⁠‍​‍‍​‌​​⁠⁠‌‍​‍‍⁠​ Its data populates the correct systems, its maintenance regime is already resourced, and customers experience continuity rather than change. That outcome is attainable, and it rests less on engineering excellence than on a single organisational discipline: maintaining an un

Picture an infrastructure programme in which every decision, from the initial investment case to the final maintenance intervention, is made at the right time by competent people holding the right information.​‌​‌​​​‌​‍​​⁠‌⁠​​‌⁠⁠​‌​‍‌​​​​⁠‍⁠ There is no rework, and nobody reopens the budget in year three. That is what a functioning value chain looks like, and it sits closer than most organisations realise. Most programmes operate differently, more like a relay in which every

Reading time: 3 minutes Here's something that's causing real confusion in infrastructure right now. Two terms are now mandatory, or close to it. The Green Book talks about Value for Money. PAS 4010 requires a System for Productivity Management. And most people think they're the same thing. They're not. And understanding the difference changes everything about how you structure your contracts and your teams. Value for Money is About the Decision to Invest Let's start here. Val

Reading time: 3 minutes In two months, PAS 4010 is published. The Department for Transport and the ICE's Infrastructure Client Group have made it clear: expectations around productivity in regulated UK infrastructure are about to shift. Most asset owners maybe treating this as compliance overhead. Fill in the spreadsheet. Tick the box. Move on. They're about to find themselves on the wrong side of the timing curve. The Problem: Mistaking a Map for a Form PAS 4010 (Productivit

Collaborative delivery models only work when everyone is looking at the same trustworthy set of numbers. Assurance is not a bolt-on to the integrated client. It is the connective tissue. The way infrastructure has traditionally been bought and delivered is, in the blunt words of the Institution of Civil Engineers' Project 13 work, broken. The transactional model piles up interfaces and hand-offs and pushes risk down the chain rather than sharing it. Everyone protects their ow

The appetite for digital change in construction is real. So why does adoption keep stalling? The blocker is rarely the engineers. It is usually the people holding the purse strings. A commercial director on a major rail programme was recently asked how ready the construction industry really was for a proactive, digital approach. His answer turned the question on its head. The appetite, he said, is already there. Most larger consultancies deploy artificial intelligence and dig

Put artificial intelligence on top of inconsistent cost data and the result is not better answers. It is wrong answers, delivered faster and with more confidence. The foundation has to come first. The pitch is everywhere. Add artificial intelligence, point it at your cost data, let it forecast and spot anomalies in seconds rather than a fortnight. There is something to it. But the pitch usually skips the awkward question underneath: what, exactly, is the tool reading? On most

Latham said it in 1994. Egan said it in 1998. The industry is still saying it in 2026. Three decades of construction reform have delivered little on cost. What, finally, is different now? Every so often the industry rediscovers that it has a problem, commissions a report, agrees the diagnosis, and largely fails to change. The same conversation has now run for thirty years, and by some counts considerably longer Simon 1944 and Banwell 1960s. Sir Michael Latham's Constructing t

A cost data problem at the bottom of a programme does not stay at the bottom. It compounds upward from every tier of the supply chain, and by the time it reaches the summit it has stopped being a spreadsheet problem. Cost assurance is usually framed as a client's concern, the programme worrying whether the numbers rising up to it are true. Sit with a tier one contractor on a billion pound job, however, and the identical problem stares back, one floor down. It is not a client

· 1 OF 6 · 2.5 MINUTE READ On a major infrastructure programme, the small things deferred to the final account have a habit of returning with interest. This is how the drift happens, and why the monthly assurance cycle is where you stop it. Every commercial manager on a large infrastructure programme knows the feeling. An application for payment lands, month end is bearing down, and something in the numbers does not sit right. The certificate still has to go out, so a judg

Here's a question worth sitting with for a moment. If you commissioned a structural engineer to design a bridge, and paid them by the hour, what would happen if the bridge turned out to be unbuildable? You'd pay for it to be redesigned. By the hour again. And if the redesigned version still had coordination problems with the drainage engineer? More hours. Nobody loses money but the client. That's not a cynical take on the profession. It's just what happens when the commercial

Britain wastes £8 billion annually on strategic national infrastructure due to deep-seated systemic inefficiencies. UK construction labour productivity has flatlined, growing at barely one per cent per year over two decades and leaving the nation lagging significantly behind France, Germany, and the United States. This stagnation is compounded by an escalating maintenance backlog and an outdated project management culture that prioritises isolated local speed over workflow p

Why PAS 4010 and Sophiotelic governance are pointing at the same failure in UK infrastructure productivity. Most UK infrastructure programmes have a productivity problem they will not name directly. You can see it in the National Audit Office reports, in the PAC hearings, in the gap between what major programmes promise at the business case stage and what they actually deliver. The pattern is depressingly consistent: technically capable organisations, significant public inves

Artificial intelligence is transforming the construction industry, from design and planning to project management and safety monitoring. Yet, as AI tools become more common on construction sites, managing their use responsibly and effectively becomes critical. The ISO 42001 (2023) AI Management System standard offers a clear framework to help construction professionals align their AI practices with best management principles. Understanding why this standard matters can help c

Who is next to walk? The most expensive asset in your multi billion pound programme is not the TBM or the digital twin. It is the collective intelligence of the people operating them. Yet the UK infrastructure sector is currently a sieve. We are not just losing people. We are losing the institutional memory required to deliver complex outcomes. At Black Pear Advisory Ltd, we see this brain drain as a structural failure to architect high integrity alliances that value human po
