Construction Quality and Speed Working Group

• NESCC Sponsored working group that will focus on:– Evaluating new technologies for decreasing construction

time and costs while improving quality – panel of experts with periodic meetings

– Identifying potential end users of the task group products, and articulating the suggested applications and extent of the applications for these end users.

– Evaluating impact on codes and standards – roadmap feedback to NESCC

– Developing feedstock for research organizations.

Construction Quality and Speed Improvement Technologies

Scope and Objectives of Task Group• This task group will be focused on building techniques and

materials which improve the speed and quality of construction and potentially lower costs.

• This will be a standing study group which would assess the efficiency benefits of a specific technology, determine what codes and standards would be necessary for regulatory acceptance and then develop a research plan to accomplish the code change.

Construction Quality and Speed Improvement Technologies

Expected Results of Task Group• The task group products would be the development of a

project proposal(s) for technological research needed for key code changes that would be delivered to the appropriate SDO(s).

• This task group would also propose discussions for the NESCC meeting agendas once discussions are mature for a given technology.

Construction Speed and Quality Improvement Technologies

Some of the initial areas that I think would be interesting to discuss are:•Accelerating the curing of concrete•Moisture tolerant concrete epoxies•Threadless Conduit Couplers•Cable splicing•SC construction•High Strength rebar•Headed Rebar•Auto Rebar Placement/Fabrication•Modular Rebar •Parallel Threaded Rebar Splices

Construction Speed and Quality Improvement Technologies (continued)

Some of the initial areas that I think would be interesting to discuss are:•Integrated pre-fab for reinforced steel •Automated Inspection technologies•Optimized modular design, procurement, and fabrication technologies•Near Site modular shop design •Just-in-time production technologies of specific size shapes•Increasing the completeness and testing of modules
