Who actually decides what happens on a construction project?
It sounds like a simple question.
The client wants something changed. The designer agrees. The contractor can build it. Everyone appears to be saying yes.
And yet the work still cannot proceed.
Why?
Because what looks like one construction decision is often several different decisions.
Someone may need authority to spend the money. Someone else may need authority to instruct the contractor. A planning authority may control statutory consent. A regulator, operator, funder, insurer, utility company or board may hold another form of authority.
None of those decisions necessarily substitutes for another.
In Nobody Knows Who Decided, Thomas Marriner follows that problem backwards.
Beginning with the everyday site question - who decided that? - the book explores the difference between authority, responsibility, expertise, influence and control. It asks why the person who knows the most is not always allowed to decide, and why the person responsible for delivery may not possess the authority required to act.
Why can a client own a project without being free to make every decision about it?
Why can a contractor control the site but not change what it has been instructed to build?
Why can a regulator, planning authority, board, lender or operator each possess a different kind of yes?
And who decided what each of those people was allowed to decide in the first place?
To answer that, the book travels from Victorian railway promoters and Railway Mania to modern megaprojects and regulated infrastructure, including HS2, Edinburgh Trams and Heathrow.
It asks what changed between the nineteenth-century railway boom and today, why authority was divided, and what each new boundary was trying to protect: public money, property rights, safety, competition, customers, the environment or the long-term operation of an asset.
The problem is not simply that construction has too many decision-makers.
The deeper problem is that projects frequently fail to distinguish between different kinds of authority.
A board approving expenditure is not the same as a contractual instruction. Technical approval is not planning permission. Planning permission is not operational acceptance. A regulator's consent is not the client's investment decision. A contractor's expertise is not authority to change the requirement.
Once those distinctions become visible, familiar problems in construction management, project management, infrastructure delivery, design management, contracts, governance and project controls begin to look very different.
The real question becomes:
Which authority is missing?
Where does that authority come from?
Who possesses it?
What still has to happen before the physical work can move?
Written from inside construction, Nobody Knows Who Decided is for project managers, construction managers, contractors, consultants, engineers, architects, quantity surveyors, commercial managers, design managers, developers and clients.
It is also for anyone interested in major infrastructure, railways, government projects, regulation, planning, corporate governance and how large organisations actually make decisions.
This is not a management manual and it is not an argument for abolishing regulation or giving one powerful person control of everything.
It asks a harder question:
If we want projects to make decisions faster, which boundaries could safely be removed - and which exist because somebody had a good reason for putting them there?
Before asking why nobody knows who decided, perhaps we should ask something more fundamental:
Who was ever allowed to decide?
