Why Detailed Site Investigation Matters In NSW

Possible Problems that Develop Through Ground Issues when Building a Structure can result in Substantial Delays and/or Increased Building Costs. Hidden Waste, Construction of Structures on Contaminated Soil, and/or Use of Poorly Constructed or Unsafe Materials are Examples of Potentially Serious Issues that may Delay or Prevent Construction Activities. 

Detailed Site Investigation NSW will Identify these and/or other Site Issues through Research, By Providing Site Analysis for All Entities that Operate From or Use the Site, and Providing Site Risk Analysis prior to Commencing Any Development Activity.

Within New South Wales (NSW) to develop land in Residential, Commercial, or Industrial applications, a Site Assessment will typically need to be completed. This can apply to Industrial Properties such as old factories, former petrol stations, and/or old storage facilities; however it should be noted that even a property that appears to be clean on the surface may contain waste products hidden below the surface.

The Goal of the Detailed Site Investigation is to identify the presence of Contaminated Soil, Abnormal Soil Conditions, and/or Potential for Contamination via Historical Land Use through Characterisation of Subsurface Samples, Groundwater Analysis, and Site History Investigation. Samples are collected from multiple locations within the site. Samples are then analysed and tested to determine whether there are hazardous soil/materials present and whether or not the site can accommodate any type of future land use(s).

Conducting a Detailed Site Investigation enables individuals to undertake informed Business Decisions, eliminates delays relating to the approval process and assists owners and developers with compliance with applicable land use and safety legislation for New South Wales..

The Role of Waste Classification in Sydney

Waste classification will also play an important part in site works. When soil and building waste are to be removed from a site, it requires sorting correctly. Legislation and guidelines regarding waste management exist in New South Wales to provide strict requirements regarding the disposal of waste as well as how the waste should be stored and the locations in which it can be disposed of.

Waste Classification Sydney determines the type and level of the waste materials present. Waste may include soil, rubble, asbestos, and other fill materials. Waste is tested to determine if it is reusable, able to be recycled or suitable for disposal.

Failure to classify or dispose of waste correctly may result in fines, project delays and/or environmental damage. Good report writing for waste provides protection for builders and owners against said fines, delays, and environmental damage.

There are many jobs undertaken in Sydney that require large amounts of material transported off-site (such as soil). If material has not been tested prior to disposal, the landfill operator may refuse to accept the material. This will delay works on-site and increase transport costs, as well as increasing the number of dump trucks required for transport
