a) Based on standard design principles and practices,
describe how the roof and drainage system of a building may be
designed.
b) Describe three main drainage systems which are
typically required in a building.
c) What are the main stages of a structural construction
project?
d) Identify at least three promising building materials’
trends in the construction industry in recent years.
My subject is Plant Engineering
A rectangular detention basin will be connected to outlet of the
above drainage system to reduce the peak flow rate to
5m3/s. Determine the dimensions of the basin if the
length of the basin is 3 times of the width. An orifice will be
used as the outlet of the basin and the depth of water above the
center of the orifice should be less than 2m. What is the size of
the orifice?
Design an I-section purlin for an industrial building
to support the galvanized
corrugated iron sheet roof with following details:
Spacing of the truss = 5.0 meter
Spacing of purlins = 1.5 meters
Inclination of main rafter to horizontal = 30o
Weight of galvanized sheets with bolts etc = 130 N/m2
Imposed snow load = 1.5 kN/m2
Wind load = 1.0 kN/m2
You are considering installing a photovoltaic (PV) system on the
roof of your one-storey home. Discuss four (4) factors that need to
be taken into consideration with the installation of a PV system
for providing electrical power to the home.
