The realization of any construction project is always a growth process based on the needs (the idea) of the client up to the eventual realization. This growth process is based on the macroscopic vision of the desired end result (the requirement programme) and is elaborated step by step in greater detail (the various steps that constitute the design phase) up to the eventual completion (the acceptance).

At the heart of this entire process are the wishes, the expectations, and the budget of the client. It is our duty as designers to use our knowledge and experience to shape these elements into a feasible project in accordance with peripheral conditions (urban planning, environmental engineering, fire engineering, accordance with legislation: ARAB (General Regulations for Protection at Work), AREI (General Regulations for Electrical Installations), EPB (Energy Performance of Buildings), etc.). On top of all this the project is required to meet the standards and technical prescriptions as they apply in Belgium.

ID adheres to the following timeline for the realization of a construction project:
 

Preliminary study

ID outlines and catalogues the wishes and the expectations of the client and moulds them into a requirement programme and budget. All necessary data concerning the site and its environment is gathered. The peripheral conditions pertaining to urban planning and administration are charted.

1. Preliminary design

ID translates the requirement programme into a layout, surface areas, volumes, and materials. The preliminary design should allow the client to form a clear image of the presented preliminary design. After that the accompanying estimates are made, and the budgets are tested.
  1. Draft design
    ID develops the models which are intended as spatial representations of the programme. By generating and investigating various spatial configurations the client is able to gain insight into the impact of the programme, the qualities of the environment and the architecture of the project about to be developed.
     
  2. Preliminary design
    In this phase the draft design is further elaborated and investigated, think: dimensions, choice of materials, implementation of technical equipment, maintenance and safety, cost, etc. The client will be able to obtain a clear and complete insight into the proposed project.

3. The building and environmental permit applications

Once the final choice of the design has been made, the dossiers are drawn up with the purpose of obtaining a building permit, environmental permit, and any possible subsidies.
 

4. Design and tender dossier

ID puts the final touches to the execution plans, specifications, takeoff lists, definitive choice of materials and finishing, etc. and creates a dossier around this. A potential contractor should be able to write up his quotation in an unequivocal manner on the basis of this dossier. The accompanying estimate is also written up by ID.
 

5. Tender

In conjunction with the client ID will compile a list of contractors to be contacted. This is up to the client.
On the basis of the complete plan dossier (architecture, stability, techniques, detailing), specifications, and takeoff list, a tender dossier is created in order to obtain an unequivocal and comparable offer from any potential contractors.

Any questions potential contractors may have are answered by ID. We also perform a review of the tenders submitted by the contractors with a proposed award candidate. In case of public tender it is only natural that the procedures prescribed by law are followed.

6. Management and supervision of the execution of the works

ID provides the necessary information to the contractor(s) and coordinates the flow thereof to the parties involved. ID organizes and leads the job site meetings as well as various technical discussions. The reports of these meetings are written up by ID.

ID regularly inspects the execution of the works, reviews the proposed and utilized materials and assesses the proposed execution method. These inspections are aimed at ensuring the conformity of the executed works with the specifications.

Budget control. ID reviews the sums of money periodically claimed by the contractor to ensure they are in accordance with the state of the executed works and the specifications, and also reviews the invoices of the contractor. ID also reviews whether the projected budget is being respected.

ID follows up on planning.
 

7. Acceptance

Following completion of the works, ID will assist the client in the provisional acceptance of the works. ID writes up an official report on the provisional acceptance.
The follow-up of the response by the contractor to the formulated remarks concerning the provisional acceptance is also handled by ID.
Upon expiry of the warranty period, ID will assist the client with the final acceptance of the works. Afterwards ID draws up the official report of the final acceptance.
 

8. Aftercare

ID supports the client with any questions or difficulties which may arise after the expiry of the warranty period.
