How we work – the stages of each project

Each Project have different stages. We explain here how we do it.

Stage 1 - Inception
Developing a clear project Brief
During the inception phase, we develop a clear project brief, appoint a consulting team and establish the specific site’s attributes including the physical, social and cultural context.
Stage 2 - Project concept
We think this is the most important stage for every project. During the concept and design stage, we prepare the concept design based on the client’s brief to portray the essence of the idea, including the narrative around the key driving the influences in the design. Further we also develop a business model or a cost plan, that we recommend to our client.
Stage 3 - Design Development
Develop the approved concept
During this stage, we develop the approved concept to finalise the design, outline the specifications, cost plan, financial viability and documentation agenda for the project.

Stage 4 - Documentation & Procurement
Prepare, Approval & Construction Documentation
During this stage, we confirm and implement the agenda for the execution of the project and submit drawings, detail plans to the local authorities for approval.
Stage 5 - Construction
Manage, Administer & Monitor the Contracts & Processes
During this stage, we administer the contracts and processes. Issue construction plans and documentation and attend regular site, technical and progress meetings.
Stage 6 - Close Out
Fulfill & Complete the Project for Close out
During the close out phase, we fulfill and complete the project close out, including the preparation of the necessary documentation to facilitate effective completion, handover and operation of the project.
