Building Design firms often provide many different design services, such as Architecture, Interior Design, Structure, Interiors, Landscape, etc. And within these broad range of groups, the actual services may relate to New constructions, Renovations, Alterations, Extensions, valuation and project assessment, project feasibility reports, etc. The projects, when handled simultaneously rarely remain within the confines of well-documented definitions. Like some pre-emptive work for interior or landscape design will occur in the architectural scheme. And when the post building construction, other services are prematurely terminated, the ‘pre-emptive’ work will not get paid.
These services occur in different schedules, and their scopes are based on very different criteria. Building design fees are chiefly collected on the basis of floor spread or footprint, except in few countries where it may be based on hours spent on it. The floor spread based varies with the type of project. Fees charged for Architectural projects include the construction cost (built-up coast) + some extra for site development design works. Similarly structural design fees are computed on the construction costs, but that may be a small part, in comparison to costs of site development works like land contouring, retaining walls and other support entities. Interior Design fees cannot always be calculated on the basis of carpet area, as lot of materials and objects are retained or reused.
In a group or associated practices the savings occur from the seamless handling of a project. This occurs when common entities are detailed or specified just once. Like for Landscape design site structures (pavings, curbs, retaining walls, water-body formations) are specified with architectural details. Electrical layout for architecture and Interior design is nearly identical.
Yet, in all these, the most important issue, vis a vis a client that comes through is, What should be, and How to determine the Cost of the job? The term Total Cost of Job nominally means to include all the costs of actually executing the designed job, similar costs of inputs from other design consultants or agencies, and the cost of all the peripheral work executed on the site through or by owners themselves or their agents, during the Currency period of the Design Services. The total Cost of Job will also include the estimated value of the work being preserved or maintained on the site.
At the start of a design project, the total cost of the job, is not available. As a result some notional figure is determined, to bill the first installment of fees or a lump-sum figure is used for first bill. This figure is determined on the basis of total cost of the job, but more importantly the intellectual rights of design formation. To determine the cost of a job, spread of the job or the built-up area is very useful. Structural engineers often base the fees on RCC (or structural) component of the project or a percentage of fees payable to the architect. Interior designers base their fees on Carpet area, but more surely on Interior Design intervention area, which is more rational or realistic. In spite of this in a group or associated practices it becomes difficult to derive a common fee’s formula.
