Virtualstep: 4d Simulation, Purdue Ect Team
ECT Fact Sheets
The main value from 4D is derived from using it proactively to visualize the construction sequence. Another benefit is the ability to run what-if scenarios to determine optimum scheduling and resource management. Also, by linking 3D drawings to a project schedule, all project stakeholders, from the owner to the tiling subcontractor, can see how the project is supposed to progress. VirtualSTEP Products include 4D Project Navigator, Conflict Coordinator, Project Reporter, and Project Analyzer. All these products are web-based.
Dma™: Digestion Material For Asbestos, Purdue Ect Team
Dma™: Digestion Material For Asbestos, Purdue Ect Team
ECT Fact Sheets
Current techniques for removing asbestos- containing fireproofing require the construction of air-tight barriers, labor- intensive scraping of the fireproofing, and the installation of new asbestos-free fireproofing. The DMATM product is the result of a joint development by W.R. Grace & Co. and Department of Energy's Brookhaven National Laboratory. The new technology uses a foamy solution sprayed directly onto asbestos-containing fireproofing. After absorbing into the fireproofing, the foam chemically digests asbestos fibers and dissolves them into harmless minerals. The process is the first to chemically destroy asbestos without first removing the fireproofing.

Asbestos Removal System (Envirosystem), Purdue Ect Team
ECT Fact Sheets
A new asbestos removal system called EnviroSystem(TM) has been developed by CUPS Systems, Inc., and GRI (Gas Research Institute). It basically comprises a portable line traveling system that is composed of a high-pressure water jet coating removal device, called HydroKleaner, a vacuum pump, a side boom, a pump sled, a process sled, and a 20 cu.yd. disposal container. The system is operated by workers wearing protective gear and clothing.
Reinforced Cage Robot For Concrete Beams And Colums, Purdue Ect Team
Reinforced Cage Robot For Concrete Beams And Colums, Purdue Ect Team
ECT Fact Sheets
The robot or machine, which builds reinforcing cages required for concrete beams and columns, places the longitudinal bars on a jig, then places and ties the hoop reinforcing bars to the longitudinal bars automatically. All the operator must do is turn the machine on, align the hoop bars on the machine, and attach the necessary rigging to the cage for removal after the machine has finished.

3d Laser Scanning & Modeling System, Purdue Ect Team
ECT Fact Sheets
Traditional methods of measuring and modeling the surface geometry of large, complex structures or sites that require engineering or survey-grade accuracy are often inaccurate, incomplete or expensive. Inaccurate or incomplete drawings and models often lead to costly construction errors or delays. A portable, auto-scanning laser and PC system that lets users economically obtain accurate, complete, and timely as-built geometry information for large structures and sites. The system can remotely measure natural surfaces up to 100m away at the speed of 800 points per second. With spacing between adjacent points as fine as 1mm, users can capture an extremely high level …
Storm Chamber Technology For Storm Water Storage And Gray Water Management And Reuse, Purdue Ect Team
Storm Chamber Technology For Storm Water Storage And Gray Water Management And Reuse, Purdue Ect Team
ECT Fact Sheets
StormChamber™ is an open bottom, arch-shaped, HDPE infiltration chamber which functions in both permeable and non-permeable soils for subsurface retention, detention, recharge and reuse of storm water, or gray water, designed to overcome the deficiencies of other technologies. It provides a higher level of nutrient and pollutant removal by taking advantage of the natural biological and physical properties of the soil. StormChamber™ systems mimic pre-development conditions by putting post-construction run off back into the ground approximately where it used to go, maintaining base flow to streams, wetlands, lakes, ponds and countering salt-water intrusion in coastal areas.
Electro Osmotic Pulse Technology For Prevention Of Water Intrusion In Concrete Structure, Purdue Ect Team
Electro Osmotic Pulse Technology For Prevention Of Water Intrusion In Concrete Structure, Purdue Ect Team
ECT Fact Sheets
Groundwater intrusion into a building can cause serious structural degradation, corrosion of expensive mechanical equipment. ElectroOsmotic Pulse (EOP) technology is based on the concept of electroosmosis; the movement of an electrically charged ion in a liquid under the influence of an external electric field. EOP not only eliminates water-seepage problems from the interior of the structure without excavation, but it further mitigates corrosion damage to mechanical equipment and reduces the interior relative humidity of the basements.
Cable-Based Water Leak Detection Technology, Purdue Ect Team
Cable-Based Water Leak Detection Technology, Purdue Ect Team
ECT Fact Sheets
Water leaks can be considered as a serious problem from many sources such as water supply and return chains, air conditioning units, cold-water chillers, clogged drains, damaged skylights or windows, or even construction errors. The new water leak detection technologies can provide significant advantages in cost, reliability, and easy adoption have continued since the traditional technology mainly focusing on a spot detector revealed several limitations.

Semantic 3d Cad And Its Applications In Construction Industry — An Outlook Of Construction Data Visualization, Zhigang Shen, Raja R. A. Issa, Linxia Gu
Department of Construction Engineering and Management: Faculty Publications
In response to the need of using electronic design data directly in construction management applications, many CAD developers have started implementing semantic data models in their CAD products using industry foundation classes (IFCs). While helpful, these semantic CAD applications have limitations when used in actual construction practices. The case studies in the thesis indicated that: 1) the semantics of the current data model (IFC as an example) is not rich enough to cover the richer details of the real trade practices; 2) the current implementation of the semantic data model lacks the mechanism to provide multiple trades views at various …
