1. Three roles and how they differ
Each protects something different.
| Role | What it protects |
|---|---|
| The designer | that the solution reaches the required result |
| Owner's supervision | that what is built conforms to the design |
| The technical consultant | that the association can cope with the procedure and the decisions |
The third role is singled out in the Estonian apartment building support context: according to professional sources, the support conditions have required a technical consultant to be involved in planning and carrying out the reconstruction works, with a contract concluded no later than the moment of submitting the application. Whether the requirement still applies and its precise wording must be checked in the regulation in force, since the conditions have differed between rounds.
2. Why supervision must not sit on the contractor's side
Three reasons, and the third is decisive. The task of supervision is to check the very thing the contractor is paid for. Where both serve the same interest, the check disappears. And the association itself has no competence to check, which makes supervision its only technical protection.
Without independent supervision the association has no way of knowing whether the insulation was installed correctly, because it is covered over. In renovation much of the work is hidden behind the finished result, and it cannot be checked afterwards without demolition.
3. What a technical consultant does
Four tasks are the hardest for an association, and the third has the greatest financial effect. It concerns preparing the procurement.
Helping to assess which solution reaches the required class. Helping to draw up the tender documents. Helping to compare tenders, the methodology for which is covered in a separate guide on budgeting. And helping to keep track of the application and reporting deadlines.
The board of an association is not usually from the construction trade, which makes comparing tenders the point where a mistake costs most. The consultant does not replace the supervision or the designer: they are competence on the association's side rather than a technical executor.
4. What to write into the contract
Four things matter more in renovation than in new construction, and the first is the most often missing. It concerns previous experience.
| What to write | Why |
|---|---|
| Who is liable if the class falls short of the requirement | the lost support is someone's risk |
| How unforeseen circumstances are handled | see forecasting the cost |
| How the work is organised in an occupied building | see living in the building |
| Who carries out the final measurements and the balancing | these are separate works |
If the class is not reached the support is lost, and the question is then whose risk that was. Liability must be divided clearly between the designer and the contractor, since the cause may lie on either side.
5. How to choose
Three criteria besides price, and the second is underrated. It concerns the ability to communicate.
Previous experience with similar apartment buildings rather than general construction experience. Willingness to explain decisions to a board of non-specialists. And availability during construction, which is decisive in the case of supervision.
The board has to be able to pass the decisions on to the apartment owners, and it cannot do that if the decisions were never explained to the board itself. Explaining is part of the work.
Summary and four practical rules
Three roles protect different things: the designer the result, owner's supervision the conformity of what is built, and the technical consultant the association's own competence, the last of which has been required to be engaged no later than the moment of submitting the application. Supervision must not sit on the contractor's side, because in renovation much of the work is covered over and cannot be checked afterwards without demolition. The contract must state whose risk a shortfall in the class is, since the cause of the lost support may lie in the design or in the execution.
Four rules: keep supervision independent of the contractor. Check whether the technical consultant requirement still applies in the regulation in force. Write into the contract whose risk a shortfall in the class is. Choose the parties on their ability to explain as well as on price.
