Lesson 7.3Lesson 7.3 · The Team, Consultants & Procurement
Procurement Routes
How a building is bought - traditional, design-and-build, construction management - and how each route trades cost, time, quality and risk
How you buy decides who carries the risk
Two clients build identical buildings. One hands the finished design to a builder and pays for exactly what is built; the other hands a brief to a single firm and pays a fixed price for a promised result. Same building, utterly different projects - different risks, different timelines, different roles, and a completely different job for the architect. The choice between them is the procurement route, and it is made, or bungled, before a single drawing is priced.
Same building, three clients, three different routes. The route follows the fear.
What 'procurement route' actually means
Procurement is simply how a client buys a building - the structure of contracts and responsibilities through which design and construction are delivered and paid for. It answers a handful of decisive questions before construction begins: Who designs, and who builds - are they the same party or separate? When does the builder join - after the design is complete, or early enough to shape it? How is the price fixed - a firm lump sum, rates against measured quantities, or the actual cost plus a fee? And, above all, who carries which risk if things go wrong - the client, the contractor, or the design team? The answers define the whole commercial architecture of the project.
This matters to the architect more than almost any other decision, because the route determines where you sit. In one route you are the client's independent adviser, holding the design and administering the contract; in another you work for the contractor and serve their commercial interests; in a third you are one of many consultants coordinated by someone else. A client who chooses a route without understanding these consequences - or an architect who does not advise on the choice - sets up conflicts that no goodwill can later resolve. Choosing the route is one of the first and highest-value pieces of advice an architect gives, and it should follow from the client's real priorities: whether they most need certainty of price, speed, quality and control, or the simplicity of a single point of responsibility. There is no best route, only the right route for this client, this project and this appetite for risk.
There is no best route - only the right route for this client and this risk appetite.
Traditional (design-bid-build)
The traditional route - often called design-bid-build - is the oldest and, worldwide, still the most common for building work. The sequence is in the name: the design team, led by the architect, completes the design; the completed design is put out to tender and contractors bid to build it; the client appoints the winning contractor to build what was designed. Design and construction are separate contracts with separate parties, and the architect typically administers the building contract during construction, certifying payment and quality on the client's behalf. Its great virtues are quality and control: because the design is fully worked out and independent before pricing, the client knows what they are buying, competition drives a keen price, and the architect remains the client's independent guardian of design intent and quality.
Its costs are time and price-certainty risk. Because design must largely finish before construction starts, the traditional route is slower than routes that overlap the two, and the client cannot begin building while still designing. And because the contractor only prices what is drawn, anything the drawings miss or the client later changes becomes a variation - extra cost and time claimed by the contractor, with the risk of that incompleteness sitting largely with the client and design team. Traditional works best where quality and design control matter most, the brief is stable, and the programme can accommodate a proper design period - a bespoke house, a considered institutional building, a heritage project. It is the route in which the architect's independent, client-side role is strongest, which is one reason the profession tends to favour it.
Design and build (D&B)
In design and build, the client contracts with a single firm - usually a contractor - who takes responsibility for both designing and constructing the building. The client sets out requirements (often prepared with an architect's help as 'employer's requirements'), and the D&B contractor delivers a finished building for a largely fixed price, carrying single-point responsibility for the whole. Its attractions are real: price and time certainty are stronger, because one party owns both design and construction and can overlap them; the client has one point of contact and, in principle, one party to blame if anything fails; and buildability is designed in from the start because the builder is designing. For clients who value certainty and speed over fine design control - a commercial developer, an industrial client, a standard building type - D&B is often the rational choice.
The trade-off falls on design quality and control, and squarely on the architect's position. In D&B the architect frequently works for the contractor, not the client - either engaged directly by the D&B firm, or novated to them after helping the client set the requirements. This changes everything: the architect's client is now a contractor with a commercial incentive to build to the minimum the contract allows, and the independent guardianship of design intent weakens. Clients mitigate this by writing tight employer's requirements and sometimes retaining a separate 'client-side' architect to monitor quality. The lesson for the practitioner is to understand exactly whom you serve before you sign - a novated architect who still imagines they work for the client, or a client who assumes their vision is protected without tight requirements, are both heading for disappointment. D&B is powerful, but it moves the architect from the client's side of the table to the builder's.
In design-and-build the architect often works for the builder. Know it before you sign.
Construction management and management contracting
When speed is paramount and the client can tolerate less price certainty, two related routes let construction begin before design is finished by breaking the work into packages let over time. In construction management (CM), the client appoints a construction manager as a professional adviser - paid a fee to manage and coordinate the works - while the client contracts directly with each of the many trade contractors. In management contracting (MC), a management contractor is appointed who in turn holds the contracts with the works contractors, sitting between them and the client. Both allow fast-track delivery, because packages can be designed, tendered and built in overlapping waves rather than one long sequence, and both keep the client close to the specialist trades and their pricing.
The price of speed is cost uncertainty and client involvement. Because the total is not fixed at the outset - the later packages are priced as design develops - the client carries more of the risk that the final cost exceeds expectations, and both routes demand a sophisticated, hands-on client (or a strong PMC) able to make fast decisions and carry more risk knowingly. They suit large, complex, time-critical projects with experienced clients - a major commercial fit-out, a phased development - far more than a one-off private client. In CM in particular, the architect works alongside the construction manager as part of a fast, integrated team, coordinating a design that is being built even as later parts are still drawn. These routes reward speed and flexibility and punish clients who wanted certainty; matching them to the right client is exactly the advice an architect is there to give.
EPC, turnkey and management by consultant
Two more arrangements complete the picture, both common in India. EPC - engineering, procurement and construction - is a turnkey route in which a single contractor takes total responsibility to design, procure and build a complete, ready-to-use facility for a fixed price and date, handing the client a finished 'turn-key' asset. EPC is the norm for large infrastructure, industrial and power projects, where certainty of cost and time and single-point accountability matter far more than bespoke architecture; it is D&B's heavy-industry cousin, with the client even further from the design detail. The client's control is exercised almost entirely through the contract and its performance specifications, so writing and monitoring those becomes the decisive skill.
The project management consultant (PMC) route is less a contract form than a management overlay: the client appoints a PMC to manage the whole delivery - the consultants, the procurement, the programme and the contractors - on their behalf. It can wrap around a traditional or D&B contract and is common on large Indian corporate, institutional and public projects where the client lacks in-house delivery capacity. For the architect, the PMC route means working within a structure where the PMC, not the architect, may hold the lead-management role - so, as Lesson 7.1 stressed, the division of duties must be agreed in writing. The broad map to carry is a spectrum of risk transfer: at one end the traditional route keeps design control with the client and design risk shared; at the other, EPC and turnkey transfer almost everything to a single contractor for a fixed price. Every route is a different answer to the question 'who carries the risk, and what does the client pay for that certainty?'
Every route is one answer to: who carries the risk, and what does certainty cost?
Item-rate versus turnkey on the ground
In India, two poles dominate everyday practice, and they cut across the formal routes above. At one end is the item-rate contract - the traditional workhorse of Indian construction and the backbone of public works under agencies like the CPWD. Here the contractor is paid for the actual quantities of work executed, measured on site against a schedule of agreed rates for each item (so much per cubic metre of concrete, per square metre of plaster). It is transparent and fair when quantities are uncertain, and it keeps the client paying only for what is built - but it offers little price certainty, invites disputes over measurement, and can incentivise a contractor to maximise measured quantities. Item-rate work sits naturally inside the traditional route, with the architect and a cost consultant measuring and certifying as work proceeds.
At the other end is turnkey (and lump-sum) contracting, where a single agency delivers a complete, finished result - often design included - for a fixed price, popular with private clients and corporates who want certainty and simplicity and are willing to trade design control for it. Between these poles sit lump-sum contracts on a fixed design, percentage-rate contracts, and every hybrid a negotiation can invent. The practical Indian reality is that the formal 'route' often matters less than these payment-and-responsibility structures, and that many projects are procured informally, on trust and relationships, without the tidy contractual clarity the textbooks assume. The architect's value is to bring clarity to this - to advise the client honestly on the trade-off they are making between price certainty, flexibility and control, to insist on a clear contract whatever the route, and to keep all specific legal and tax questions with a lawyer and a chartered accountant. Whatever the local custom, the underlying logic is universal: someone always carries the risk, and the price reflects who.
Item-rate: pay for what's built. Turnkey: pay a fixed price for a promise.

Workshop - recommend a route for three different clients
This exercise builds the judgement an architect is paid for: matching a procurement route to what a client actually fears and values. You will reason from priorities to a recommendation, and see how the same building demands different routes for different clients.
The route comparison from this lesson and honest reasoning; no software needed.
Goal: a reasoned procurement recommendation for each of three clients Inputs: three client briefs (below) and the routes from this lesson Time: ~60 minutes
- 1Take three clients: (a) a family building a bespoke home who care most about design quality and control; (b) a developer building a standard office block who care most about fixed price and speed; (c) a corporation building a large campus fast, with an experienced in-house team.
- 2For each, name their single most important priority (certainty / speed / quality / simplicity) and their tolerance for risk and involvement.
- 3Recommend a route for each and justify it in two or three sentences - and say explicitly where the architect sits and whom they serve under that route.
- 4For each recommendation, name the biggest risk the route leaves on the table (e.g. variations, quality slippage, cost drift) and one thing you would do to manage it.
- 5Now flip one client's priority (the family suddenly needs a fixed price and a fast move-in) and show how your recommended route changes - proving the route follows the priority, not the building.
You’ll walk away with
A one-page procurement recommendation for three clients, each with the priority diagnosed, a route justified, the architect's position stated, and the main residual risk and its mitigation named.
Three altitudes on the same idea
Read the band that fits you — or all three.
Advising on the procurement route is one of the highest-value services you offer, and you should give it before the design is priced, not after. Diagnose the client's real priority - price certainty, speed, quality, or single-point simplicity - and match the route to it honestly, even when the route that is best for the client (say, D&B) weakens your own independent position. Above all, know exactly whom you serve under each route, and never let a novation or a PMC quietly move you to the other side of the table without a written scope.
As the project lead, the route shapes your entire delivery: in traditional you manage a clean design-then-build sequence with variations to control; in D&B you deliver buildability and defend the employer's requirements; in fast-track CM you juggle packages being built while later ones are still drawn. Know which risks your route leaves with the client and manage them actively - variations and scope creep in traditional, quality slippage in D&B, cost drift in construction management - because the route tells you exactly where your job will try to go wrong.
Studio never mentions procurement, yet it decides who you work for and what your job even is. Learn the four or five main routes and, for each, three things: who designs and builds, when the builder joins, and who carries the price risk. Then notice that the 'best' route depends entirely on what the client fears most. Understanding this early will make you unusually useful in practice, because most young architects can design but cannot yet advise a client on how to buy the building.
“Design and build is a cheaper, faster, better modern way to procure - so a good architect should steer clients toward it and away from the slow, old-fashioned traditional route.”
Do it yourself
Reason from priorities to a route on projects you know.
- 1For your last project, which route was used - and did anyone consciously choose it, or did it just happen by default?
- 2Name a client who most needs price certainty and one who most needs design quality. Would you recommend them the same route? Why not?
- 3Under design-and-build, who does the architect actually work for on your project - and is that written down?
- 4In an item-rate contract, where does the price risk sit, and what tempts a contractor about how work is measured?

Once a client and route are chosen, the building has to be priced and a contractor selected - which is its own discipline of pre-qualification, tender, bid evaluation and award, with a famous trap at the end. That is tendering and bidding, where we finish the module.
