BUNGALOW / HOUSE DESIGN AND BUILD
FROM CONCEPT TO COMPLETION
For more than 10 years, Ecotec has fine-tuned the design-build construction process to enhance opportunities before, during and after a facility is built. Our goal is to bring the full resources of our in-house team to provide an organized and efficient design-build construction experience.
By hiring Ecotec, we assume responsibility for the entire design and construction of your project. You do not have to navigate multiple contracted entities. In addition to reducing risk and improving schedule performance, this makes for a more enjoyable project delivery.
The advantage of design-build construction provided by Ecotec is that services can take place simultaneously. Earthwork can begin while the design is underway, for example. Compressing the schedule translates into cost savings for you. This is especially true at Ecotec, where design, automation solutions, and construction management are all offered in-house. Communication is ongoing with no gaps.
Ecotec is your one-stop-shop for design-build construction. With all the services required for a successful project located under one roof, we combine technical ability with ease and efficiency.
THE ONLY PARTNER YOU NEED FOR YOUR CONSTRUCTION NEEDS
THE PROCESS
Below is our FLOWCHART OF STANDARD OPERATION PROCEDURES (S.O.P.) for Design & Build Construction of your dream house
(the flowchart is prepared in Bahasa Melayu)
CONSTRUCTION METHOD
LGSF System in Brief
Light Gauge Steel Framed Structures (LGSF) is based on factory made galvanized light gauge steel components,
designed as per codal requirements, produced by cold forming method and assembled as panels at site forming
structural steel framework of a building of varying sizes of wall and floor. The basic building elements of light gauge steel framing are cold formed sections which can be prefabricated on site using various methods of connection. The assembly is done using special types of screws and bolts.
Cold formed sections are widely used in construction including residential floors, industrial buildings, commercial buildings, hotels and are gaining greater acceptance in the residential sector. LGSF is already well established in residential construction in North America, Australia and Japan and is gaining ground in Malaysia as well. LGSF is typically ideal for one to three storey high buildings, especially in residential homes, apartments and
commercial buildings. Due to its flexibility fast construction and durability, this technology has great potential for counties like Malaysia.
LGSF can be combined with composite steel / concrete deck resting on light steel framing stud walls. Apart from having potential for mass housing, modular buildings can be used for long term temporary or permanent structures such as schools and classroom, military and civil housing needs, post – disaster relief structures and industrial buildings
Specifications for the System
Structural Section
Main Section are Studs & Track.
Studs serve as a general all purpose framing component used in a variety of applications including external curtain walls, load bearing walls, headers floors & roof joists, soffits and frame components. Track is used as closure to stud and joists end as well as head and sill conditions. It is also used for blocking and bridging conditions. Load bearing steel framing members shall be cold – formed to shape from structural quality sheet steel .
Wall frame
Consists of top track (U shape configuration) with a depth compatible with that of the studs of the same nominal size. Minimum height of track flanges shall be 19 mm.
Load Bearing Walls
C section studs with depth of 90 and 200 mm and thickness between 2.7 mm and 2.0 mm shall be provided at a distance of 300 mm / 400 mm / 610 mm to ensure the efficient use of cladding material. Multiple studs are used at heavily loaded application such as adjacent to openings or in braced panels. C section with 94 x 50 mm is used for noggins. Alternation shall be required for the local details at the head & the base of the wall to
ensure that loads are adequately transferred without local deformation of the joists & studs.
Non Load Bearing Walls
It is similar to that of load bearing walls except that noggins and diagonal bracing arenot required to stabilize the studs.
Deflection Limit of Walls
Suggested deflection limit for external walls subject to wind loading are as follow:
—>Full height glazing Height / 600
—>Masonry wall Height / 500
—>Board / reduced finish Height / 360
—>Steel cladding Height / 250
—>Other flexible Cladding Height / 360
Wall cladding
Wall cladding shall be designed to resist wind load. Sheet has to be screwed to the joist / purlin with maximum spacing of 300 mm c/c. All the joints of sheet in longitudinal direction require a minimum lap of 150 mm in order to make them leak proof. Following materials are generally used on wall cladding:
• Gypsum board
• Heavy duty cement particle board
Bracing
Bracing and bridging shall have configuration and steel thickness to provide secondary support for the studs in accordance with the relevant specification for the design of Cold – formed steel structure of members.
Floor frame
For speed of construction, floor joist may be pre-assembled to form floor cassettes. This works well for regular floor places but care shall be taken when the geometry of the building requires the cassettes to vary in size with location or when non – right angel corners are required. Resistant may be provided to the top flange of the joists by the flooring board. The floor should be designed for the combined effect of dead and imposed load.
The construction of a suspended floor comprising cold formed steel floor joists is similar to that for a floor using timber joists. The strength to weight ratio of light steel joist is higher than that of other material. Steel joists are stable and do not suffer, the long term problems of drying out, creep and Shrinkage. Joists are generally positioned at 300, 400 & 600 mm centres, depending on the spacing capabilities of the floor materials used.
Roof frame
Flat roof is made up of joists. Where steel decking form a flat roof, a minimum fall of 1:4 should be introduced to ensure that any moisture runs off. To avoid local ponding to rain water, the pitch may need to be increased to overcome the effective reduction in roof angle caused by the deflection of long span roof purlin or decking.
Roof truss
Use of Light Steel roof truss is very economical for larger span building, an attic or open roof truss creates usable roof space, uses fewer components than Fink truss and provides an economical solution, since it utilizes the high strength of the steel members. The trusses are placed at 600 mm maximum spacing and are battened and tiled in a conventional manner.
Construction
Foundations for light steel framing are essentially the same as for any form of construction, although dead loads applied by the light steel frame will be much lower than in the concrete or masonry construction. Construction phases of steel buildings resembles the phases of conventional reinforced
concrete buildings. The sections, manufactured as per design are numbered properly. The profiles are sent to site either as profile or panellized parts, considering the distance of the construction site and transportation conditions. Profiles are assembled by trained assembly team at the construction site in line with the architectural plan. Only special studs are used during assembly, no welding is done. Once the assembly is done, the frame is filled with insulation materials (fibreglass, rockwool etc). Walls are then covered with standard boards or similar approved materials.
The sequence of erection
- foundation laying,
- fixing of tracks,
- fixing of wall panelswith bracings as required,
- fixing of floor panels,
- fixing of roof panels,
- decking sheet,
fixing of electrical & plumbing services - and finally fixing of insulation material &
walling panels.
Electrical Gas and plumbing, services are installed through pre-punched service holes in the web of the steel forms. Plastic grommets and silicon seals are used to fasten and protect wiring and pipes from corrosion and damage arising from vibrations
Electrical cables running within floor insulation layer in the separating floor construction should be protected with cartridge fuses or mini circuit breaker.
Wall panels are generally made by using heavy duty Cement Particle Board and Gypsum board. It can also be made using high density extended polystyrene core plastered from outside using wire mesh and chicken mesh. Galvolume sheet of appropriate thickness can also be used as cladding.
