Q1: Foundation type
The design of the foundation footing is normally based on the stability of the soil, type,
topography of the site as well as any other local requirements as outlined during design. The site
is classified as class M by the Residential and Footing Code AS2870. The site is classified as M.
Class M sites are moderately reactive silt or clay sites. Most of these site experiences ground
movements that are moderates as a results of the conditions of the soil and changes in the
moisture (Brodsky and Yankelevsky 2017).
The most adequate foundation footings for the site is and pier or beam footings. The footing
beams for brick veneer and brick cottages that are on reactive soils often need piering to the
stable grounds. Piering is often needed in cases where the footing is under the influence of
adjacent drainage or even water board sewer mains (Massone et al. 2017). Sites that are
composed of highly reactive grounds or even uncontrolled filling need piering for the footings
for every construction type.
Q2: Section through X-X

Q3: Construction sequence
Excavation of the pier hole- the spacing, number as well as location of the holes will be indicated
by the engineer’s drawings on the design
 Pouring of the concrete in the piers- The concrete is put at about 500mm beneath the
NGL or FGL and does not require any reinforcement
 Excavation of the strip foundation-strip foundation is excavated between the piers after
three days. The concrete beams would be excavated around the whole perimeter of the
house
 Position of the steel reinforcement for beam: This is done as determined by the structural
calculations that aid in the determination of the spacing as well as the sizes of the bars to
be used
 Pouring the beam: The beam is made of reinforced concrete that has been adequately
mixed

 Construction of the external wall on the surface of the beam. The external walls are
constructed using the recommended material which is masonry bricks or concrete
depending on the prevailing conditions of the site and the intended use of the structure to
be constructed
Q4: Layout of structural columns and beams
b) The layout of the structural for the beams and columns has been settled on depending on the
form of the building on which a structural grid is to be laid. The architectural layout of the
building is more of repetitive and regular and hence the patterns of the layout of the structure are
in the form of a rectangular grid lattice. This would ensure quick and accurate lying of the grids
as just the span of the columns and the depth of the beams will need to be calculated to find the
adequate spacing.
Q5: Beams
a) The cross section of beams recommended for this building would concrete beam.
