Modular Construction

•The modular construction industry has made signifi ant advances in implementing processes and materials to build and deliver more sophisticated and complex facility types.

•Modular for multi-story, steel framed structures are becoming more popular.

•Modular for health care

•educational structures,

•and large scale military projects

•Always known for its time saving advantages,

•modular is now being recognized for being a more resource efficient, inherently greener process.

•Studies focusing on construction efficiency have documented 25 to 50 percent waste in coordinating labour and in managing, moving, and installing materials.

Modular Constructi

on •Opportunities for Breakthrough Improvements

1•Widespread deployment and use of

interoperable technology applications, also called Building Information Modelling (BIM);

Modular Construction

2•Improved job-site efficiency

through more effective interfacing of people, processes, materials, equipment, and information;

3•Greater use of prefabrication,

preassembly, modularization, and off-site fabrication techniques and processes;

Modular Construction

4 •Innovative, widespread use of demonstration installations;

5•Effective performance

measurement to drive efficiency and support innovation.

Modular Construction

Manufacturing building components off-site provides for more controlled conditions and allows for improved quality and precision in the fabrication of the component.”

Modular Construction

•The five activities are interrelated, and the implementation of each will enable that of the•others.

Modular Construction

•There must be a strategic, collaborative approach towards these five approaches

Interoperability

Is the ability to manage and communicate

electronic data among people such as:

owners

clients,

contractors

Modular Construction

and across a project’sdesign, engineering, operations, project

management, construction, financial, and legal units

Modular Construction

This has been made possible by a range of information technology tools and

applications including: computer-aided design and drafting (CADD)three– and four–dimensional visualization

and modelling programslaser scanning

cost-estimating and scheduling toolsmaterials tracking.

Effective use of interoperable technologies requires:

integrated

collaborative processes

effective planning up

front

Interoperable technologies can also help to:

Modular Construction

Innovative, widespread use of demonstration

Installations field testing on a job site; seminars, training, and conferences; scientific laboratories with

sophisticated equipment and standardized testing and reporting protocols.

Modular Construction Demonstration Installations can be

used to show the effectiveness of: new processes technologies materials and their readiness to be

deployed throughout the construction industry.

Modular Construction By allowing determinations to be

made about whether innovative approaches are mature enough for general use

demonstration installations can help to mitigate innovation– related risks to owners, contractors, and subcontractors.

Modular Construction

Effective performance measurement to drive

efficiency and support innovation Performance measures are enablers

of innovation and of corrective actions throughout a project’s life cycle.

Modular Construction

They can help companies and organizations

understand issues such as: how processes or practices led to

success or failure, improvements or inefficiencies, and how to use that knowledge to improve products, processes, and the outcomes of active projects.
