Footing system
The type of foundation footing used in the structure is pier foundation footing system. A pier
foundation is composed of numerous cylindrical columns that have large diameters and are used
in the support of the superstructure as well as in the transfer of the super imposed loads to the
stable and firm strata below1. Pier foundation stands some feet above the ground level and is also
known as post foundation. Masonry or concrete pier and drilled caissons are the main type of
pier foundation footing commonly used. In the above pictures, the former foundation footing
system has been adopted. Masonry or concrete piers are usable depending on the stratum level
and in most cases used go as high as 5m in which masonry piers are used. The depth of the bed
and the nature of the soil determine the shape and size of the pier.

Structural systems
The structural connections create a balance in the building structure against such forces as
compressive and tensional forces2. The structural connections as well aid in the facilitation of te
transfer of the load from the super structure to the stable stratum below. Column to footing
connections facilitate the transfer of the load from the ground floor level through the columns
into the foundation where the load is distributed over the foundation. Beam to column footing
facilitates the transfer of large super imposed loads from the upper floors through the columns to
the stable stratum3.

Floor systems
The floor system used in the upper levels of the building is reinforced concrete floors. Concrete
floor systems exist in various forms and are used in the provision of thermal comfort as well as
other advantages. The floor systems can be either on-ground, suspended or a combination of
both. Conventional concrete is found to be containing high amount of embodied energy. From
the provided pictures of middle rise building, the upper levels have on-ground concrete floor
system. Slab-on-ground concrete floors have two variants: waffle pod slabs and conventional
slabs having deep excavated beams4.
