Organization of information is critical when it comes to making design decisions, estimating costs, and constructing a building. Structuring project data in an efficient manner allows members of the project team to make rigorous analysis of options to compare cost, risk, performance and design attributes. This can be accomplished through the SPD, which stands for Systems and Performance Description. It is a way of documenting design in a highly efficient manner, offering tremendous value to the construction team. It combines an early project narrative with UNIFOMAT organization for ease of estimating.
