What "losing control" really means
The fear of losing control in fact covers two distinct anxieties, which it helps to separate.
The first is the fear of no longer understanding the figures — of receiving a bulky document full of measurements and unit rates without being able to validate it. That fear is well founded if the economist does not document their assumptions and does not take the time to explain their choices. It disappears with an economist who presents their work transparently: assumptions stated, bands justified, risks flagged.
The second is the fear of no longer being able to take the right decisions, because the expertise sits with the provider and not in house. That confuses technical expertise with decision-making. The economist brings the expertise; the decision always stays with the client or the architect. A good external economist does not take decisions in their client's place, they give them what they need to decide with full knowledge.
ℹ The right question to ask Not "do I understand how the economist calculated this?" but "do I understand what the figures mean for my project and the decisions I have to take?" What is outsourced is the calculation, not the judgement. The judgement stays with you.
In house or outsourced: the real comparison
| Criterion | In-house economist | Outsourced economist |
|---|---|---|
| Fixed cost | Salary and on-costs, 65–90 k€ a year fully loaded | None; a variable cost per assignment |
| Availability at a peak | Limited to one person | Capacity adjustable to volume |
| Specialisation by project type | Generally a generalist | Possible: choose the right profile |
| Continuous knowledge of the project | Strong, the economist follows everything | Depends on the quality of the brief and the follow-up |
| Responsiveness to a one-off question | Immediate | Depends on availability |
| Independence from the client's decisions | Sometimes compromised by hierarchy | Total, an outside view |
| Control over the quality of the deliverable | Direct | Through the brief for the assignment |
| Suitability for one-off or unusual projects | Limited outside the speciality | Strong, select the right profile |
| Access to market databases | Depends on subscriptions held | Included in the fee |
The table shows the question is not "in house or outsourced?" but "for which assignments and at what frequency?" A developer with a steady pipeline of ten operations a year often benefits from an in-house economist for the routine stages, using external help for specialist assignments or peaks. An independent architect delivering two or three operations a year has no economic interest in bringing the function in house.
Which assignments to outsource, by profile
| Assignment | Architect with no economist | Developer / social landlord | Public client |
|---|---|---|---|
| Outline estimate | ✓ Routine | ✓ Supporting the in-house team | ✓ Systematic |
| Developed-design measure | ✓ Routine | ✓ Supporting or supplementing | ✓ Systematic |
| Tender package: specification and schedules | ✓ Complete assignment | ~ Partial, ordinary packages | ✓ With engineering coordination |
| Tender analysis at award | ✓ Routine | ~ Support on complex packages | ✓ Mandatory on public contracts |
| Cost control on site | ✓ Where there is no site coordinator | ~ According to in-house resources | ~ Often kept in house |
| Producing the final account | ✓ At the end of the assignment | ~ Support on disputed packages | ✓ Systematic |
| Budget optimisation on an overrun | ✓ Urgent one-off | ✓ Urgent one-off | ✓ Urgent one-off |
Complete outsourcing suits architects with no economist of their own, and public clients on their statutory assignments. For developers and social landlords a hybrid is common: an in-house team for daily monitoring and the routine stages, external help for the complex assignments or an overrun.
How to keep control with an outsourced economist
Define the assignment clearly before it starts
The first instrument of control is the brief. Before any commission, the architect or client defines precisely what is expected: which stages are covered, which deliverables in what format, what deadlines apply, what base assumptions are to be adopted. A precise brief is the best protection against misunderstanding and disappointing deliverables.
Insist on transparent assumptions
Every estimate or measure delivered by an external economist must come with a note of assumptions: the reference areas used, the ratios adopted and their source, the correction factors applied, the items treated by assumption. Without that transparency the deliverable is a black box — impossible to validate, impossible to update.
Build in review points at each key step
Outsourcing does not mean an absence of dialogue. A review of the outline estimate before it goes to the client, a review of the developed-design measure before the tender package is launched, a meeting to present the award report: these synchronisation points let misunderstandings be corrected early and confirm that the economist has taken the project's specifics on board.
Keep the trade-off decisions in house
The basic principle is simple: the economist prices the options, the architect or client decides. The decision to revisit the brief, to adopt a technical variant or to accept an overrun always belongs to the client, not to the economist. Formalising that separation of roles at the start of the assignment avoids drift into the economist taking decisions that are not theirs.
The signs of a good outsourced economist
Not all providers are equal. These are the criteria that distinguish a reliable external economist from someone merely executing:
- They document their assumptions systematically: every figure comes with its method and its source.
- They flag risks proactively: they do not simply produce a total, they identify the items at risk and the residual uncertainties.
- They offer alternatives: faced with an overrun or a structuring technical choice, they price several scenarios without imposing one.
- They meet the deadlines announced: a late estimate can hold up a funding approval or a planning submission.
- They are available to explain their work: a deliverable with no discussion of its findings is an incomplete deliverable.
ℹ What should stop you An external economist who refuses to document their assumptions, who delivers figures with neither a band nor a risk note, or who cannot answer "on what basis did you calculate this item?" is not offering the minimum transparency required. Transparency is not a comfort; it is the condition on which outsourcing stays an instrument of control rather than becoming a black box.
What outsourcing to Quostra changes in practice
Quostra is built so that outsourcing cost studies is fluid and transparent. Every deliverable comes with a detailed note of assumptions, a stated band and an identification of the items at risk. Deliverables are supplied in editable formats — Excel for the financial tables, Word for the written documents — so that client or architect can bring them into their own tools.
Communication during the assignment is direct with the economist responsible, not through a salesperson or an intermediate project manager. And every deliverable is presented in a meeting or a call before final issue, so that adjustments can be made and questions answered.
You have better things to do. Submit your project on quostra.com and an economist takes on your cost studies with total transparency on the assumptions.
In summary
Outsourcing cost studies does not mean losing control, provided the assignment is defined precisely, transparency of assumptions is insisted on, and the trade-off decisions stay in house. The right model is neither wholly internal nor wholly external: it is an intelligent hybrid that draws on the external economist's specialisation while keeping the strategic steering with the client or the architect. The key is the quality of the brief and the quality of the debrief.
