New Construction Techniques

• Raft foundation which uniformly distributes heavy loads to the land (Builds stronger foundation and increases the life of the building)

• Shear wall is a new technology which replaces ordinary columns, uniformly disperses external pressures (heavy wind and earthquake force) and gets a strong grip to the ground

• MIVAN technology - Aluminium Formwork - speed of construction, quality of construction, seismic resistivity and its economy)

• Innovative Silicone Technologies - adhesives and sealants (prevents air & water intrusion & provides excellent insulation between window layers)

…Contd…• Plaswall is a range of custom-manufactured modular walls

which can be made at a movable factory at site and suit any design or architectural requirement. It is a fast and clean concrete walling system and is ideal for warm climates while also providing insulation in cold temperatures. Plaswall is suitable for all types of construction, right from small housing projects to villas, to commercial structures.

• The Sterling Construction System is a new age panelized building technology based on ‘Lost-In-Place’ Formwork, which is an evolutionary solution for the fast growing construction Industry. The system was commercially launched in 2000, as a fast, reliable and cost effective construction system having customized applications. The System is based on pre-engineered formwork systems to build load and non load bearing walls.

APPLICATION OF MAGNETIC TECHNOLOGIES IN CONSTRUCTION INDUSTRY

•First observations and scientific works on application of magnetic fields in the production of cement, ceramics, brick, casting forms, etc., were carried out in the former USSR, in 1962.

•Government of the Russian Federation, issued a decree No1058 on 14 October 1993 on a Federal Program "Application of magnetic fields in national economy", based on which, State Construction Committee of Russia, created a range of documents, ordering their organizations to use magnetic technologies. This decision was made in order to economize on cementing and ferro-concrete reinforcement, to increase cement product's strength, to increase life of constructions and to intensify various technological processes.

•In some areas during production of cement and other construction materials, there is a deficit of fresh water. Many years' observations and practice show that application of magnetic systems allows using salty and even seawater. When using magnetized seawater for cement kneading, cement strength increases by 30-40% and the economy on cement becomes 14%

•While transporting concrete mixtures on long distances, its plasticity decreases by 30-40%. This leads to concrete's inability to lay properly and increases energy expenses when electro-mechanical vibrators are used. In this case, it is wise to use our magnetic system designed for magnetization of ready-made concrete at industrial areas. This technology allows not only to increase concrete's plasticity but, at the same time, allows to increase its resistance to pressure by 15-25% and tensile strength by 30-40%

Emerging Construction Technologies

• Emerging Construction Technologies could produce a "High Impact" in the construction industry

• The technologies are divided into five areas: Civil, Mechanical, Internet-based, Electrical, and Others

Civil Technologies                               

SUPER THERM barrier maintains heat on the surface side of the building - will not allow penetration. One of the most successful applications of SUPER THERM is in the treatment of roofs and walls of commercial and residential structures as a barrier against heat and cold. Over the past few years SUPER THERM has been well proven in a variety of countries, such as Australia, Canada, Colombia, Japan, United Arab Emirates, and USA

Super Therm - Ceramic Paint Insulation

SUPER THERM can be used for concrete walls

Soundless Chemical Demolition Agents

Rock Demolition Pier Demolition

Soundless chemical demolition agents (SCDAs) have proven to be viable substitutes for the use of explosives. SCDAs are powdery materials that will expand considerably when mixed with water. This expansion, when occurring under confinement, generates significant expansive pressures. Depending on the type of SCDA, significant expansive pressure may be generated as quickly as within 15 min., or as long as within 24 hr

Civil Technologies contd….Ultrascreen: Sight and Sound Barrier

                              

Easy Panel InstallationAnother attractive feature of the panels is its low cost

Panels have been widely used for many years to act as sight and sound barriers in most of the highways and in residential areas where visual privacy is needed. Also, panels are used by persons living close to roadways and where it is desirable to minimize distractions caused by noise. The need of privacy fencing around commercial property and residential areas most of the times can be satisfied with cement or wood panels among others.

This type of flex anchor is used to provide freedom of movement for GFRC cladding under changing temperature and moisture conditions

GFRC Facade Panels with Steel Stud/Flex Anchor ConnectionThe ability of building cladding systems to perform successfully depends primarily on their proper design and construction.. The facade and its attachments (using GFRC) are not being adequately implemented to accommodate vertical and horizontal differential movement between the panels and concrete frame which is resulting in failure or cracking of the panels, and chipping off of the supporting concrete. Thus, there is a need for a system that provides freedom of movement under changing environmental conditions and that establishes sufficient rigidity under gravity, wind etc

The Technology Contour crafting is a fabrication process by which large cale parts can be

fabricated quickly in a layer by layer fashion. This technology uses conventional robotics and a novel extrusion system to rapidly build three dimensional objects. Concrete is the primary material that is used by Contour Crafting, however, a variety of paste materials such as adobe, ceramics, gypsum and even wood chips mixed with epoxy may be used by the process.

The Benefits• Contour Crafting has a strong potential to provide homes to disaster

victims in a very short time. • A Contour Crafting machine can build a 2,000 square foot house with all

utilities for electrical and plumbing in less than 24 hours. • CC eliminates the need to transport large prefabricated structures long

distances, saving the time and costs associated with transportation. • As this is an automated process, labor needs are highly minimized.

Foundation

Lateral STATNAMIC Testing

STATNAMIC device

Lateral loads, which are analyzed using static soil response parameters, usually control the foundation design. These are normally dynamic loads caused by earthquakes, ship impacts and wind. When feasible, design parameters are checked with full scale static loading testing. The traditional static testing is very costly, dangerous, time consuming, and limited to loads that can be generated by a hydraulic jack.

•STATNAMIC applies loads up to 30 MN (3,400 tons).•Foundations tested include high capacity drilled shafts, steel piles, auger cast piles, timber piles, batter piles in clay, rock, silt, and sand.•STATNAMIC can test bridge foundations, pile groups, spread footings, and off-shore piles.•STATNAMIC can test the lateral capacity of foundations.•Production piles can be tested without prior planning. No reaction piles are required.•Three 600 ton tests can be conducted in a one day shift.•Several STATNAMIC tests can be conducted for the cost of a single static test.•STATNAMIC loads the pile and soil together.•The duration of loading is on the order of 10 Hz.•STATNAMIC's built-in load cell and laser sensor provide direct measurements of load-displacement behavior.•STATNAMIC produces load-displacement results immediately on site.
