Options appraisals are undertaken following feasibility studies in order to assess potential options before proceeding to concept design.

Feasibility studies do not involve 'design' as such. They are preliminary studies whose purpose is to:
*Establish whether the project is viable.
*Assist in the development of the strategic brief.
*Aid in the identification of feasible options.

After assessing feasibility studies, the client will decide which options the consultant team should develop. Ideally there will be no more than four options at this stage. If more options exist it may be necessary to carry out further high-level studies before proceeding to the more detailed analysis required for the options review report.

Options appraisals are not designs, their purpose is to enable the client to understand the broad pros and cons of the available options so that a preferred option can be selected.

Options appraisals are diagrammatic options studies. The design team may, in discussion with the client, generate several alternative strategies for developing a site, exploring the advantages and disadvantages of various options and then agreeing the best way forward. This is a process of strategic assessment of development possibilities, often with a preferred direction selected. Much of this work will be diagrammatic, and at this stage is not a ‘design’.

These studies allow further assessments and discussions:
*The CDM co-ordinator (if appointed at this stage) assesses the risks of the options in relation to the CDM regulations.
*The architect co-ordinates consultations with the local authority and other statutory authorities, and assesses possible planning permission requirements and other statutory requirements (such as the need for an environmental impact assessment for the options).
*The cost consultant prepares initial cost appraisals of the options.

Preparing appraisals for these options may require further site surveys or site information. It may also be necessary to commission additional advice, such as planning advice, expertise on rights of light, engineering advice, or other specialist services depending on the complexity of the project. The need to commission other consultants early in the process will often be determined by the scale and location of a development and also by the client’s familiarity with the site and the local area. A large-scale development with underground constraints will almost certainly require engineering expertise in the early stages, whereas a residence in a traditional street may not. Both however may require an understanding of local authority or other statutory consultee positions.

The lead consultant can then co-ordinate the preparation of a draft options review report, from which the client can either select a preferred option or instructs further options or appraisals.

The options review report might contain:
*A general description of the options.
*Diagrammatic sketch layouts.
*The overall consequences of each option for the client's operations.
*Assessment of compatibility with the clients vision, mission and objectives.
*Assessment of the overall feasibility of each option.
*Potential for future-proofing.
*Planning permission issues (including the potential requirement for an environmental impact assessment).
*Sustainability considerations.
*Impact on the local community and environment.
*Third party dependencies.
*Value management exercises.
*Whole-life costs with a rudimentary assessment of costs/sqm, configuration and servicing.
*Time-frames, phasing and key milestones.
*Procurement route.
*Risks.
*Recommendations.

At this stage the client’s brief is likely to expand, partly from the conclusions of feasibility appraisals but also from knowledge gained by research into planning precedents, legal issues, engineering data and the technical constraints and nature of the project.

Once a preferred option has been selected, the consultant team may carry out further assessments to assist the client in preparing a business case and project execution plan before concept design begins.
