The advanced BOX system optimizes the use of walls both as partitions and structural elements.
CHB-walls (cement hollow blocks) are redundant (they don't carry stuctural loads) and are messy and time consuming. We still see the CHB system in the Philippines because maybe;
1. They do not know that the system exists,
2. The first cost of the form system is too high for the contractor to invest,
3. They do not know how to use the system.
Box System is a solid reinforced concrete structural system.
DURABLE - strenght has a premium between 8 to 12% in cost
FAST - faster by 20 to 30% (10 months reduced to 8 months or even shorter).
COST COMPETITIVE - because you eliminate the cost of plastering (BOTH SIDES), you save labor when you shorten construction period
QUALITY - self-levelling, self-plumbing, self-90 degree, self-alligning, no cracks, no "kapak"
Construction is ‘technology-based’ and one has to adept with change for the better.
SYSTEM CONSTRUCTION ( BOX SYSTEM)
Walls / Column
SYSTEM CONSTRUCTION of residential and commercial buildings in the Philippines is greatly changing the atmosphere of construction. This FAST, DURABLE, and COST-EFFICIENT construction method eliminates plastering and makes redundant the 'cement hollow blocks’ ( CHB ) walls in the Philippines. This method of construction uses US Patented Formwork Panels (multiple sizes) that are laid side by side and/or on top of the others to form the core of partitions/walls/columns of any structure. This core is then poured with fresh concrete mix; allowed to set; and stripped. This work cycle generates a fast production of structural building elements (equivalent to plastered shear wall) incomparable with conventional system.
For example, the structural phase (including plastering) of a low cost house with a floor area of 24 to 36 sq. m. with enclosed bathroom, bedroom, and its perimeter walls can be finished in 2 days work cycle, assuming that the soil has been prepared to receive the slab-on-fill.
After stripping the US Patented Formwork Panels we see a fully-built structural house with precise door and window openings and smooth wall surfaces (both face) that are ready to receive any kind of architectural finishes (painting after drying period).
Large projects like mass housing, big residential houses and multi-storey buildings can be fast tracked by increasing the quantity of these US Patented Formwork Panels.
Unlike the conventional system of construction ('cement hollow blocks’ are not designed to carry structural loads), this BOX system optimizes the use of walls both as partitions and structural elements. Shift from frame structural resisting elements (footing/column/beam/slab) to box type (grade slab-on-fill/wall/slab) gives the owner better value for his/her investment. Lastly, this structural design and construction concept are made to pass Universal Design Standards and National Building Code of the Philippines.
Thickness of wall; 100 mm for one floor; 150 mm for 2 floor.
