Excavations for a new Pool Oakford-Byford-Darling Downs-Piara Waters.

Before Excavating the hole for a pool installation 

Apply for a building permit for your pool installation anyone can apply for a building permit, the owner, pool builder or barrier installer. Applicants can choose to submit either a certified or uncertified application for a pool.

Prior to a building permit being granted by a permit authority (usually the relevant local government), a registered building surveyor is required to confirm that the proposed pool and its safety barrier comply with the applicable building standards by signing a ‘Certificate of Design Compliance’ (CDC). The applicable building standards include the: • structural adequacy of the pool or spa; • water recirculation system;
• energy efficiency for heating and pumping; • water efficiency (ie a pool blanket or cover that is designed to reduce water evaporation and is accredited under the Smart Approved Watermark Scheme www.smartwatermark. org); and • safety barrier. Anyone can apply for a building permit, the owner, pool builder or barrier installer. Applicants can choose to submit either a certified or uncertified application for a pool installation and its safety barrier.

A certified application (Building Commission form BA1) is submitted to the permit authority accompanied by a CDC. This requires an independent building surveyor to certify the plans and specifications and provide a CDC. The permit authority has 10 business days to decide on a certified application. An uncertified application (Building Commission form BA2) is submitted to the permit authority without a CDC. The permit authority must appoint an independent building surveyor to check the proposal and provide the CDC. The permit authority has 25 business days to decide on an uncertified l and its safety barrier.

As part of the process for obtaining a building permit, a registered building surveyor assesses the plans and specifications and certifies that the pool and its safety barrier will comply with the applicable building standards prior to issuing a CDC. Also at the completion of the work, the person named as the builder on the building permit must provide the permit authority with a ‘Notice of Completion’ (Building Commission form BA7). This notice must be accompanied by an inspection certificate that confirms the safety barrier complies with the Building Regulations 2012 (the Regulations). This inspection certificate is separate to the four yearly pool inspection carried out by the relevant local government

When you purchase a pool, you need to decide if you are going to organise your own safety barrier or you would like the pool builder to do this on your behalf. The responsibility for compliance of the safety barrier will depend on the person named as the builder on the building permit as outlined in the options above.

Once you have sorted all the building permits and what barriers are required, then contact Dobson Excavations talk with Bruce on 0414755306  we will excavate your pool hole for your pool installation and if a tight access  is a problem or require rock hammering is required …

Safety for ground workers near earthmoving contractors with machinery.

A traffic management plan is required to be planned developed and implemented. Determine access points of the site, view where machinery will travel and operate from personnel staff will be working. A map can be created that clearly marks the areas where machinery and or pedestrians cannot go. Ensure break areas and parking facilities will have good visibility and clear of machinery operations. Staff personnel should have safe and clear walkways to and from these areas.

Excavators, Bobcats, Traxcavators, Loaders etc have blind spots in areas around their machinery, blind spots preventing the operator from seeing persons or objects within certain angles, directions, etc.

Summary of Work place, Plan Work, develop and implement a traffic management plan and train persons on no go zones, Know the blinds spots of equipment, Use controls cameras, alarms equipment reserve beepers.

That is why safe work practice should be in place, also personal staff and people near sites should be aware that Earthmoving contractors of machinery operators can not always see them.

Septic and Soak wells Supply and installed Perth- Dwellingup-Blytheswood-Meelon

Septic domestic systems consists of tanks and Leach Drains, Septic tanks are for the settlement of the solid waste and the remaining liquid is deposed of through Leach drains, usage of the drains is adjusted via a diverter.

Leach drains can be installed either below or above the ground (inverted). This depends on the water table, clay or rock content of the ground, for inverted leach drains a pump tank with an alarm is required in addition to the septic tanks.

Soak wells tanks in concrete are used for drainage of water from rain run off, from roof down pipes, its  a method of increasing infiltrations into the ground. The Soak well tanks have holes in them to allow the water to filter into the ground. Soak wells and Septic systems are best purchased in concrete, as concrete last longer, plastic depending on the quality can spilt underground or collapse.

At Dobson Excavations we can supply your concrete soak well and septic system/leach drains, from a quality supplier, excavate the hole, install, connect piping, and back fill.

Dam Clean Outs, Construction & Extending Blytheswood-Pinjarra-Meelon-Oakley 

Clean out dams for silt build up, silt is a granular material consisting of sand and clay, silt can cause erosion of the dam, so removal of the silt material is required, this will allow more water volume in the dam.

Construction of dams of any size and this is how:

Determine the water required each day (per litre), also remember evaporation and seepage losses per day occurs as well. The size and where the dam will be constructed.                                   Construct the Dam during the dry season.                                                                                                                                                                                                                                                                                        Council approval is required so check with your local council before constructing.                                                                                                                                                                                                                  Strip topsoil because it contains organic matter (such as roots) which prevents proper compaction and may provide seepage routes (piping) once the organic matter has decayed.

Drainage Solutions Perth-Lake Clifton-Preston Beach-Capel-Myalup

Different Drainage Solutions.

Surface Drainage is the removal of water that collects on the land surface. Surface drainage system consists of shallow ditches and should include land smoothing or land grading. This type of system is suitable for all slowly permeable soils and for soils with Fragipans and clay sub soils

Stormwater pit is a water collection pit or storage container for stormwater. It is not designed to hold all the run off but needs to be large enough to contain the water pouring into it long enough to allow it to drain through the drainage pipes at a rate that keeps up with the flow of water.

Drainage Pit is a dry well, a dry well is underground structure that disposes of unwanted water most commonly surface run off, and stormwater. In some cases grey water a larger open pit and artificial swale that receives storm water and dissipates it into the ground is called an infiltration basin or recharge basin.

Rubble Pit is a trench filled with blue metal gravel and topped with sand to help disperse and remove stormwater. (The pipes from the new addition) connect to the pit with a section of slotted pipe (in the pit) a section of slotted pipe (in the pit) dispersing water through the gravel.

Headwalls or wing walls improve the flow of water into and out of conduits provide anchoring support for the pipe and prevent dislodging under excessive pressures control erosion an scour resulting from high velocities and turbulences and to prevent adjacent soil from sloughing into the water way opening.

End wall The brick, concrete or stonework construction at the sides of an excavation built to carry a flat or arched roof also called sidewall.

A Culvert is a structure that allows water to flow under a road, railroad, trail or similar obstruction from one side to the other side. Typically embedded so as to be surrounded by soil, a culvert may be made from a pipe, reinforced concrete or other materials.

Types of Culverts for Drainage Solutions

Pipe culvert (Single-Multiple), Pipe Arch Culvert (Single-Multiple), Box Culvert (Single-Multiple), Arch (Single-Multiple), Bridge (Single-Multiple), Metal Box Culvert…
