New Building Approach

From our knowledge of projects, the following solutions to the hydraulics component consistently stand out.

  • That a system of syphonic drainage be investigated for the disposal of roof and stormwater run off, as against a traditional gravity system where large roof areas and box gutters exist.
  • Compliance with the relevant Australian design standards and other authoritarian bodies.
  • Maintaining the functionality of the application whilst ensuring that the items identified here are included.
  • Identification and treatment of specific individual wastes generated within each area. Clearly recognising the need for separation of these wastes to confirm with relevant legislation and reduce operational issues due to the nature of the wastes.
  • The analysis of specific wastes and the selection of the appropriate materials to convey the waste from the building, taking into consideration the projected life span of the building.
  • That the implementation of ring mains for the hot and cold water service is best suited for the distribution of water throughout the various levels of new buildings, as opposed to a more traditional network system of distribution piping. This provides flexibility for future alterations.
  • Evaluation of the user requirements for hot water rather than adoption of traditional guidelines.
  • The provision of warm water via thermostatic mixing valves or a warm water system although well known, as a mandatory requirement is generally not addressed in a holistic approach to rationalise their locations and maintenance needs. We approach each project on its merits and in conjunction with the associated user groups provide the right system to meet the client’s needs within the guidelines of the required standards.
  • Identification of the relevant zones within the building, the provision of the appropriate water supply, pressure, flows, temperatures and redundancy (where applicable).
  • The implementation and maintenance of a backflow prevention programme is paramount in protecting the potable water supply from contamination from internal sources within the building.
  • Ensure good accessibility of services for maintenance and future extension.
  • The implementation of electronic flushing devices and flow control devices to conserve water usage.
  • The possible use of stormwater detention for landscape watering and fire fighting purposes.
  • The use of polypropylene products for the transportation of liquid wastes. Review the application of polyethylene products where the wastes are suitable and where the potential long term risks associated with the use of a material lesser than polypropylene are acceptable by the client.
  • The use of polypropylene for the transportation of water supplies to ensure longevity and to aid in the prevention of bacterial growth in the potable water supply.
  • The implementation of an alternative/ post disaster potable water supply in the event of mains systems failure, where applicable.
    Adopting maximum use of mains pressure water supply to minimise Mechanical Supplementation.

SPPG identify areas of repetitive work and endeavour to refine their simplicity in cost through careful detailing of the constructability and prefabrication of the elements.

We also identify pipeline systems that could utilise common bracketing within the project. This assists in reducing both cost and time components in the overall installation.

During the Design Development Stage, and after initial approval of proposed fixtures and tapware schedule, we establish a complete set of samples for review by the Project Team and most importantly the ‘users’. The samples displayed include pipe materials, safety equipment, floor grates, flushing devices etc, in addition to the customary taps and basins.

Finally, we implement our own internal peer review process, whereby an independent Designer objectively reviews, comments and discusses all of the noted areas as previously identified, to provide a value adding approach.
