Ongoing development
A specialised street design and build company: build-up, landscaping, and the particular expertise of designing urban streets and parks, with standing arrangements with city authorities to deliver them.
The gap this fills is institutional rather than technical. A city authority can procure a road. It cannot easily procure a street, because a street is a road plus drainage plus shade plus lighting plus places to sit plus a surface a trader can work on plus a boundary that respects the plots — and those sit in different departments, different budgets and different years.
So the street is delivered as a series of unrelated projects and the result is a road with a pavement added afterwards and a drain that floods the pavement. Everybody involved did their part.
A single entity that takes the street as one object, with a standing arrangement to build them repeatedly, changes the economics. Repetition is what makes quality affordable: the same bench, the same tree pit, the same kerb detail, built fifty times, gets cheaper every time and better every time.
The authority gains a partner that can be held to a standard rather than a contractor that can be held to a specification. And a city that builds fifty streets a year with one team learns something, which a city that tenders each street separately never does.
The risk is capture — a standing arrangement with a city is a monopoly with a friendly face — so the arrangement needs to be a framework with published standards, not an exclusive contract.
Build the same good street many times. That is the whole strategy.
