Anyone building with a general contractor hands over a great deal of responsibility and faces an experienced professional as a layperson. This is exactly where client representation comes in:
It actively represents your interests towards the general contractor, checks the work delivered, the variations and the quality, and makes sure you get what was agreed. Unlike owner's advisory, which advises selectively on single questions, client representation supports the project actively and continuously.
It evens out the imbalance between an experienced contractor and a private client. raumwert plus takes on this role as an independent body that represents your interests only.

Are you facing the general contractor alone?
Independent client representation makes sure your interests count on the construction site.
1. What is client representation?
Client representation actively represents the client's interests towards everyone involved in the build, and above all towards the general contractor. It is the client's professional voice: it checks the work and the quality, reviews variations and makes sure that what was agreed is actually delivered.
At its core it comes down to one thing: it makes sure your interests are represented in the project, even if you are not from the industry yourself. Client representation acts independently of the contractor and solely on your instructions.
2. What is the difference from owner's advisory?
Owner's advisory advises selectively, for example on a single question or a single decision. Client representation goes further: it supports the project actively and continuously and represents you towards third parties. Advice gives answers, representation acts in your name.
When independent support is worth it in general is covered in the article When is a building consultant worthwhile. Client representation is the more active, ongoing form of that support.
3. Client representation general contractor: why it matters most
The client representation general contractor projects need starts from a simple fact: you hand the execution to an experienced professional who follows their own commercial logic. Without a professional counterpart on your side, the client often notices only late where quality has been reduced or the scope of works interpreted narrowly. How much you hand over depends on the procurement model: general contractor (GU), total contractor (TU) or trade-by-trade contracting.
Client representation provides that counterpart. It checks whether the general contractor delivers what the construction contract promises, and puts your position on an equal footing.
4. What tasks does client representation cover?
The tasks depend on the mandate, but they typically cover ongoing control and representation.
Review of the construction contract and the specification before signing
Checking variations and claims for additional costs
Monitoring quality and the agreed standard
Support during sample selection and important decisions
Attending site meetings as your voice
Support at handover and with defects
That covers exactly the points where laypeople are at a disadvantage against the general contractor.
5. When should client representation start?
The earlier the better. The greatest leverage is before the construction contract is signed, because at that point everything is still negotiable. How much a contract review matters is covered in the article Have the construction contract and specification checked.
A later start still makes sense, for example when variations get out of hand or questions of quality come up. What matters is not to wait until problems have escalated.
6. How does it protect against additional costs and loss of quality?
Client representation checks every variation before you agree to it and makes sure that only what is justified is charged. It controls whether the quality delivered matches the agreed standard and steps in before defects arise.
How additional costs can be kept under control in general is covered in the article Cost control during the construction phase. Client representation puts that control into practice actively and in your name.
7. Does client representation take over construction management?
No. Construction management is the operational running of the site and lies with the general contractor or with the appointed construction manager. Client representation has to be kept clearly separate from it: it controls and represents in the client's interest, but it does not run the site itself.
This separation matters because it secures independence. Whoever runs the build cannot neutrally check their own work at the same time. Client representation therefore deliberately stays outside the operational construction management.
8. What does client representation cost?
The costs depend on the scope of the mandate, from selective support through to continuous representation. In early phases that are hard to estimate, billing by time spent with an estimate of hours is usually the fairest option; as soon as the scope is clear, a lump sum can be agreed.
Service | Scope | Guide price |
Review of construction contract and specification | One-off, before signing | approx. CHF 1,000 to 2,500 |
Selective support | Individual decisions or variations | by time spent, approx. CHF 150 to 180 per hour |
Ongoing representation during the construction phase | Continuous, through to handover | approx. 0.5 to 1.5 per cent of the construction sum |
Guide values, depending on the project and the scope. Representation often pays for itself through a single reduced variation.
Measured against the construction sum and the possible additional costs, client representation is inexpensive. It often pays for itself through a single variation that is avoided or reduced.
9. Which typical mistakes does it prevent?
Client representation stops you from accepting variations unchecked, from having quality quietly reduced and from taking important decisions under pressure and without expertise.
It equally stops you from overlooking defects at handover or missing the deadline for the notice of defects. It makes sure you are professionally represented at every critical point.
10. Three practical examples
Practical example 1: The variation that was checked
A general contractor submitted several variations. Client representation checked them and established that part of the work was already owed under the construction contract. The claim was reduced accordingly.
Practical example 2: The reduced quality
On one project the standard delivered deviated from the specification. Client representation spotted the deviation early and enforced the agreed standard before construction continued.
Practical example 3: The clean handover
At handover, client representation documented the defects in full and made sure that notice of them was given within the deadline. That kept the client's warranty rights intact.
11. Frequently asked questions about client representation
What is the difference between client representation and owner's advisory? Owner's advisory advises selectively on single questions. Client representation supports the project actively and continuously and represents the client towards third parties, in particular towards the general contractor.
Do I need client representation if I am building with a general contractor? That is exactly when it makes most sense. With a general contractor you hand over a lot and face them as a layperson. Client representation provides the professional counterpart and represents your interests.
Does client representation take over construction management? No. Construction management runs the site operationally and lies with the contractor or the construction manager. Client representation controls and represents independently in the client's interest, without running the site itself.
When should client representation start? Ideally before the construction contract is signed, because at that point everything is still negotiable. A later start is possible, for example when variations or questions of quality come up.
What does client representation cost? The costs depend on the scope. In early phases, billing by time spent with an estimate of hours is usual, later a lump sum. Measured against the construction sum it is inexpensive.
What tasks does client representation cover in concrete terms? The scope depends on the mandate and ranges from reviewing the construction contract and the specification before signing, through checking variations, to monitoring quality and the agreed standard. Added to that are support during sample selection and important decisions as well as attending site meetings as your voice. You are also supported at handover and with defects.
12. How raumwert plus represents you
Facing a general contractor, you need a professional voice that represents your interests only. That is the client representation general contractor projects call for, and raumwert plus takes on the role as an independent body: it reviews contracts and variations, controls quality and represents you at the decisive points.
That way you are not building alone against an experienced professional, but on equal terms. The framework for this is the owner's advisory service from raumwert plus.
Are you facing the general contractor alone?
Independent client representation makes sure your interests count on the construction site.
