Construction Methodology
Our construction methodology emphasizes precision, efficiency, and sustainability, utilizing advanced techniques and materials to ensure high-quality and durable structures.
Site Clearance / Preparation
Site clearance or preparation will to done before the setting out of building outline and the installation of any civil elements.
The removal of heavy and light vegetation will be done with the aid of a bulldozer and hand held cutting equipment. Thereafter the existing grade will be scarified to 150 mm depth to remove existing vegetation rooting system.
Further grading will be done to establish proposed development level for sub-grade, formation level and base for substructures, roadways and driveways.
Special Substructure
There is a section of the proposed development where there is evidence of underlying massive to thickly bedded, dense, dolomitic limestone. In this section, construction of the substructure will be done by the removal of the heavy vegetation from the building site, methodically cleaning the rock surface of remaining soil, hacking rock surface, and then drilling epoxy and dowel rebar in place thus securing the substructure in place.there exist highly karstic irregular limestone surfaces, penetrated by hollow dissolution cavities and extensive fissure, the substructure is to be constructed using a reinforced concrete spread footing. This will support reinforced column and beam elements below the entry slab.
Superstructure
The superstructure will be cast in place reinforced concrete walls and slabs, stairs and other structural elements framed by “MEVA formwork systems” that will be supported by the various substructure.
Substructure
All substructures to be constructed in the north western and south western sections of the proposed development, where the grade is at 6 to 18 degrees slope and greater, will utilize strip footing foundation.
The strip footing foundation will be 450 - 600 mm wide by 250mm thick, cast at 1m below reduced grade with 150mm thick reinforce concrete wall up to underside of entry level slab.
All substructure elements will be reinforced adequately to support the superstructure and backfill below slab shall be approved and compact to at least 90% modified proctor density, ensuring that the allowable bearing capacity of 266 Kpa (5.57K.s.f.) is achieved.
The substructure to be constructed n the northern eastern section of the proposed development, where the grade is flat or moderately sloping, will be a raft foundation.
The raft foundation will be constructed with a 150 mm thick reinforced slab and ground beams internally and along the perimeter. The raft will be cast in a minimum of 150 mm thick approve fill on top of the reduced grade and compacted to at least 90% modified proctor to ensure that the allowable bearing capacity of 266 Kpa (5.57K.s.f.) is achieved.
In the North western section where there exist highly karstic irregular limestone surfaces, penetrated by hollow dissolution cavities and extensive fissure, the substructure is to be constructed using a reinforced concrete spread footing. This will support reinforced column and beam elements below the entry slab.
