Design for Construction framework


The Design for Construction framework is developed within CRUX project "Design for Construction" of STAR research program "System engineering in construction" at VTT Building Technology

STAR project CRUX deals with the problem of constructability. It focuses particularly on how the product - building and building products - contributes to the ease of construction and the project is aiming at developing tools and methods to improve the product in respect of the constructability.


Baseline

Construction process is typically fragmented; it is difficult to consider in the design phase all the requirements set by different phases of the product realisation process and by later phases of the life cycle of the building. Thus systematic means for information feedback through the whole construction process is needed in order to anticipate requirements in the later phases of the process.

Manufacturing industries have developed systematic methods to evaluate manufacturability and assemblability (DFM and DFA). Still these are mainly intended to be used with small products which are manufactured in large batches. There are not means for systematic diagnostics of assemblability and constructability of large one-of-a-kind products, such as a building.

Deliverable

Design for Construction -framework. This is a description of the process how to adopt production requirements into the product in the design phase. Furthermore required methods and tools needed in different phases of the process are identified and selected tools will be developed. The process is generic and it is applicable to manage also other requirements than those of production (i.e., maintenance, etc..).

One of the above mentioned methods is a method to identify the factors impacting constructability. Method covers all the components of constructability, i.e., manufacturing, assembly, transportation and construction.

Exploitation

There are two distinct dimensions in the design for construction framework. The first deals with product development and the other deals with project specific design. They are both applying continuous improvement and team work. In project specific design the concept which best fits the project is selected and adapted into the project. In product development concepts for different purposes are developed and improved based on the feedback from the realised projects.

Design for Construction framework will be exploited to build company specific databases for constructability information. Quality information which helps in getting the construction process right at the first time will be collected.

Impact on process lead time

Design for Construction framework is directly contributing to construction lead time. First it supports the construction project team to design the building according to the goals that the project has. Secondly it will help to develop products suitable for rapid construction.
