    In times of volatile building costs, builders will look at ways of reducing the risk of signing “fixed price” contracts with clients, contracts which leave the builders bearing the total burden of fluctuating costs over the construction period. In the last boom, massive increases and fluctuations in the price of roof tiles, steel and copper […]

    Solar Panels

    Solar Panels, known as Photovoltaic (P.V.) cells convert sunlight directly into electricity. The first PV silicon cells were invented in 1954 in the United States by 3 men working at the famous telephone company Bell Labs. Since that day PV cells have been used to provide power to everything from satellites in space to remote outback farms. […]

    Roof Frames

    Both timber and steel are used in roofs. Each material has advantages and disadvantages. Supporters of steel roofs (which are being used nowadays by a number of major builders) argue that it is more environmentally friendly, fire safe and termite proof. However the timber industry rejects these arguments, stressing the high level of embodied energy […]

    Solar Power System

    The Solar Panels collect the sunlight and create energy. They are attached to the roof by high strength rails able to withstand wind, rain and hail. The energy flows through to the Inverter which converts the current from Dc to AC (to usable household power).   A Bi-directional meter records the amount of power being […]

    Salinity and Construction

    Salt attack is an increasingly important problem in Western Australia due to our high level of coastal development and a growing salinity problem in our wheat belt and agricultural areas. Damage to buildings by “urban salinity” or “salt damp”, results from salt and water moving through capillary action through the pores of materials such as […]
