The tight access excavation minimum width depends on the dimensions of the machinery being used. Gate width, pathways, nearby structures and working space all need to be checked before equipment is brought onto the property.

Responsibility depends on the circumstances and whether reasonable precautions were taken before digging. Hobart Trees states that its operators follow site plans and take care to safeguard stormwater, sewerage, water, gas, electricity and NBN services during excavation. A Dial Before You Dig excavation protocol, now accessed through Before You Dig Australia, is also an important part of checking underground infrastructure before excavation.

Site prep soil compaction testing measures whether prepared soil has reached the density required for the intended use. Hobart Trees provides site preparation and levelling and states that its operators consider topsoil quality and land gradient, but the website does not specifically list soil compaction testing as a service.

An excavation sediment control plan can use drainage, erosion and sediment controls to keep disturbed soil on site and prevent sediment entering stormwater systems or waterways. EPA Tasmania identifies these as key controls during ground-disturbing work.

Clean fill dirt removal disposal depends on the type and condition of the excavated material. Hobart Trees offers excavation for site preparation and site clean-ups, while EPA Tasmania notes that clean fill produced during excavation must be managed and disposed of in accordance with applicable waste requirements.
