SOFTWARE PROCESS

The software process involves the input of standard architectural drawings that are electronically analysed and transformed into Hi-Tech System panels. The process is as follows:follows:

First, floor plans and elevations are either received in CAD format or are scanned and converted to electronic plans. The software then proceeds through a number of iterations to determine the optimal panel layout and configuration. As there are no moulds or standard

l h bl d l l h fpanel sizes, the computer is able to determine optimal panels without restrictions of size and shape. Therefore, iteration may yield a panel layout where no two panels are alike. From the first series of iterations, a three-dimensional model is developed which shows how the building will look and how the panels will come together. At this point, the developer d d h f f h b d h h h b lddecides on the type of finishing to be used. The program can then cost out the building and offer a series of price scenarios, which show various finishing options. With the choice of final finishing, the program then determines critical loading factors.

A second computer program is then used for determining structural analysis. Typically, for a 280m2 (3,000 sq. foot) home, seventy or so iterations are developed, all of which are structurally sound. The program then seeks out the optimal structure based on weight, cost, and strength components and the final panel boundaries are set. After optimisation, the program determines stress contours on each panel and develops stress contours on the concrete.

SOFTWARE PROCESS (cont..)

Redundant concrete (concrete which serves no structural purpose) can represent up to Redundant concrete (concrete which serves no structural purpose) can represent up to 65% of total panel volume. Based on the stress contours, the program eliminates all redundant concrete. With the elimination of 60-65% dead weight, the remaining 35-40% maintains a large latent structural load resistance, especially with respect to dynamic loading (dynamic loading which is stress caused by the movement of thedynamic loading (dynamic loading which is stress caused by the movement of the building, is particularly important during an earthquake). When concrete is removed from a panel, the program automatically replaces it with rigid insulation, reducing weight and cost, but increasing thermal and sound baffling properties. In addition to the structural capabilities a final check of stress points is undertaken to assure the soundness ofcapabilities, a final check of stress points is undertaken to assure the soundness of design.

When complete, the program stores the precise instructions needed for the computer-aided manufacturing process.

This software represents one of the most important features of IHI technology. The software continues to be developed to reflect newly created solutions in product and production process.

MANUFACTURING FLOW

Manufacturing Flow The panel manufacturing process can be divided into three distinct operations: Preparation and cutting of structural steel and rigid foam unit Preparation of panel structural components (drill, punch, robotic and

automated welding), integrating with foam and applying concrete and/orstucco)Finishing of panels to specifications (flooring roofing utilities etc ) Finishing of panels to specifications (flooring, roofing, utilities, etc.)

1) Preparation and Cutting: Once the software has determined the optimal panel configuration and

t t l l t th i f ti i t f d t th t id dstructural layout, the information is transferred to the computer-aidedmanufacturing units in the plant. To maintain efficiency, all material is shapedand prepared prior to its entry into the production line. This includes cutting,drilling, shaping, punching and welding all steel components. It also includes

tti f th t t l t l d i id f i C tti i l thcutting of the structural steel and rigid foam pieces. Cutting involves a three-dimensional contouring of the foam as prescribed by the software. In effect,the foam acts as an interior form and displaces redundant concrete.

After preparation, material is sorted into the correct assemblies and taken by lift truck to be stored near the area in the production area where it is to be used.

2) Structural Components, Foam Integration, Concrete Application:

2) Structural Components, Foam Integration, Concrete Application:

Structural steel is cut automatically to length and automated templates are used to either punch or drill holes where needed. Joint pins are pressed into place andeither punch or drill holes where needed. Joint pins are pressed into place and joints are welded or connected into place. Hooks for holding steel mesh are welded to structural tubes, as are saddles. From a template, welded wire mesh and stucco mesh (if an exterior panel) is cut to size.

The pre-formed foam core is laid down on the mesh and building paper and structural members are placed on top. With the aid of a hydraulic/pneumatic jig, the frame is assembled and electrical boxes are put in place as required. The structural members are then tensioned with cables and turnbucklesstructural members are then tensioned with cables and turnbuckles.

Concrete is then poured on the panel and troweled smooth. After setting, the panel is turned over and a protective coat is applied on both concrete surfaces.

3) Finishing) g

3) Finishing

Panels that are custom finished are completed in a similar fashion to conventional construction.This includes roofing, flooring, door and window installation, and bathrooms/kitchens ifrequired. However, if above are done in a controlled environment in the factory, the IHIsystem will gain further advantages. In the future, the company will start working onimplementing a process to begin automating the finishing process.

Factory window installation in panels provides the purchaser with a series of benefits. First,Factory window installation in panels provides the purchaser with a series of benefits. First,because there is no window frame (the frame is part of the structural steel frame of the panel),windows are purchased frameless and as such are about 30% cheaper. Second, because thesteel window housing is an integral part of the panel, windows are much more secured. This isvery important in regions subject to hurricane-force winds. In a hurricane, the windows (andvery important in regions subject to hurricane force winds. In a hurricane, the windows (andoften the roof) are generally the first to be damaged - not by debris, but because they areblown out of their frame. Once a window is gone, there is an increased vacuum effect withinthe house causing more windows to go and generating more damage.
