A pre-construction site inspection is a structured check of a site before any building or civil work starts. It confirms the site is ready and safe to work on by looking at access, ground conditions, underground and overhead services, existing structures, neighbouring properties, permits and site setup.

Pre-Construction Site Inspection: A Practical Checklist and Guide

Most problems on a construction site are cheaper to find before the first machine arrives. A buried service nobody located, a neighbour’s cracked wall nobody photographed, a site with nowhere safe to unload: each one costs time, money and sometimes safety once work has started. This guide covers what a pre-construction site inspection should include, how it differs from a pre-construction condition survey, and how to run and record the inspection so issues get fixed before day one.

Key points

• Inspect the site before work starts, and again if the scope, layout or conditions change.
• Cover access, ground and drainage, services, existing structures, neighbouring properties, environment, site setup and permits.
• A pre-construction condition survey (dilapidation survey) is a separate record of neighbouring properties. Many projects need both.
• Specialist items such as geotechnical testing and hazardous materials surveys need qualified professionals.
• Every issue you find should become an action with an owner and a due date, closed out before work starts.

What a pre-construction site inspection covers

A pre-construction site inspection is usually led by the builder, project manager or site supervisor, often with the safety officer and, where needed, specialists such as a geotechnical engineer or hazardous materials assessor. The aim is simple: know what you are building on and around before you start.

The inspection feeds directly into planning. What you find shapes the site layout, the traffic and delivery plan, the excavation approach, the risk assessments and the safe work method statements for the job. It also gives you a dated record of the site’s condition before work began.

Site inspections vs condition surveys vs stage inspections

Several different inspections happen around the start of a project. They are easy to mix up, but each has a different purpose.

For ongoing checks once work is under way, see our guide to construction site safety inspections.

Pre-construction site inspection checklist

Use these headings as the basis for your checklist, then add items for your type of work, site and state.

1. Site boundaries and access

• Boundaries, survey pegs and setbacks confirmed and marked
• Safe entry and exit points for vehicles, plant and pedestrians
• Space for deliveries, unloading and material storage
• Emergency vehicle access and assembly points
• Public interface: footpaths, road frontage and any need for traffic management

2. Ground conditions and drainage

• Geotechnical report reviewed, or testing arranged by a qualified geotechnical engineer (for residential slabs and footings, site classification is covered by AS 2870)
• Slopes, fill, soft ground and signs of previous excavation
• Natural drainage paths, ponding and flood risk
• Ground stability near planned excavations and plant set-up areas

3. Underground and overhead services

• Underground service plans obtained through Before You Dig Australia and checked against the site
• Services located and marked on the ground by a qualified locator where excavation is planned
• Overhead powerlines identified, with exclusion zones for cranes, tippers and elevating work platforms
• Temporary power, water and connection points confirmed

4. Existing structures and hazardous materials

• Condition of any existing buildings, walls, retaining walls or structures to be kept or demolished
• Asbestos and other hazardous materials identified by a competent person before demolition or refurbishment
• Signs of contaminated land, buried waste or old fuel tanks
• Structural assessment arranged for anything that may be affected by the work

5. Neighbouring properties and the public

• Pre-construction condition survey arranged for neighbouring buildings where the work could affect them
• Dated photos of fences, driveways, kerbs and footpaths next to the site
• Noise, dust and working-hours constraints noted
• Neighbours and other stakeholders identified for communication

6. Environment

• Erosion and sediment control needs
• Trees and vegetation to protect or remove, with any approvals required
• Stormwater, waterways and drains that need protecting
• Waste and spoil storage and removal plans

7. Site setup and amenities

• Site fencing, gates and signage
• Location of the site office, toilets, drinking water and lunch facilities
• First aid kit, fire extinguishers and emergency contact details
• Parking, laydown areas and plant storage
• Lighting and security

8. Permits, plans and documentation

• Planning and building approvals in place and conditions understood
• WHS management plan prepared where the project requires one
• Safe work method statements ready for any high-risk construction work
• Traffic management plan, road occupancy or footpath permits where needed
• Emergency plan and site induction content prepared

How to run a pre-construction site inspection

1. Review the documents first. Go through plans, approvals, the geotechnical report, service plans and any previous reports before you go to site.
2. Choose the right people. Bring the site supervisor and safety officer, and book specialists for items such as geotechnical testing, service location or hazardous materials.
3. Walk the whole site. Work through the checklist section by section, including boundaries, neighbouring properties and the road frontage.
4. Record everything with photos. Photograph existing damage, hazards and site features so there is a dated record before work starts.
5. Turn findings into actions. Give every issue an owner and a due date, whether it is a missing permit, a service to locate or a fence to repair.
6. Update your plans. Feed the findings into the site layout, risk assessments, safe work method statements and induction.
7. Confirm close-out before work starts. Check that every action affecting safety or access is complete and signed off before the first crew or machine arrives.

WHS duties to be aware of

Safe Work Australia’s model Code of Practice: Construction work (November 2024) explains several duties under the model WHS laws that link directly to pre-construction planning. In jurisdictions that have adopted the model WHS laws:

• A construction project is one where the cost of the construction work is $250,000 or more. These projects need a principal contractor.
• The principal contractor must prepare a written WHS management plan before the project starts.
• A safe work method statement is required for high-risk construction work.
• Before excavation, reasonable steps must be taken to get current underground essential services information and give it to the people doing the excavation.

Requirements vary between states and territories, and Victoria has its own OHS laws, so check the legislation and codes that apply to your site. Our guides to risk assessments in construction and JSEAs cover the next steps in planning the work.

Common pre-construction inspection mistakes

• Rushing the walk-around. A quick look from the road misses drainage, access and boundary issues. Walk the whole site.
• Relying on service plans alone. Plans are a starting point. Locate and mark services on the ground before excavating.
• Skipping specialists. Ground conditions, hazardous materials and structural issues need qualified people, not a best guess.
• No record of neighbouring properties. Without dated photos or a condition survey, it is hard to respond to damage claims later.
• Findings with no owner. A list of issues in a report does nothing unless each one is assigned and followed up.
• Treating it as a one-off. Re-inspect when the design, staging or site conditions change.

Digital pre-construction inspections

A paper checklist and a phone full of unlabelled photos make it hard to prove what you found and when. With a digital checklist, the inspector works through each section on a phone or tablet, takes photos against each item and signs off on site. Checklists can be completed without coverage and submitted with a tap once the device is back online.

In DIGI CLIP, anything that needs attention becomes an action in the Action Log with an owner and due date. Overdue actions trigger alert emails, and a close-out form records the fix. The completed inspection, photos and close-outs can be exported to PDF or Excel for the client, the principal contractor or an auditor. You can use the same app for plant pre-starts and equipment inspections once work is under way.

Illustrative scenario: a pre-start walk on a commercial fit-out

A site supervisor walks a site the week before a commercial project starts, using a DIGI CLIP pre-construction checklist. She photographs a damaged kerb and a cracked neighbouring fence, flags that the delivery gate is too narrow for the concrete trucks, and notes that the service plans show a gas line near the planned excavation. Each item becomes an action in the Action Log: the photos go to the client, the gate is widened, and a locator marks the gas line. By the first day on site, every safety-related action has been closed out, and the record shows exactly what was found and fixed.

This scenario is illustrative. It shows how a builder could use DIGI CLIP and is not an account of a specific customer.

Frequently asked questions

What is a pre-construction site inspection?

A pre-construction site inspection is a structured check of a site before building or civil work starts. It confirms the site is ready and safe to work on by looking at access, ground conditions, services, existing structures, neighbouring properties, permits and site setup.

What should a pre-construction site inspection checklist include?

Include site boundaries and access, ground conditions and drainage, underground and overhead services, existing structures and hazardous materials, neighbouring properties, environmental controls, site setup and amenities, and permits and documentation.

What is the difference between a pre-construction inspection and a pre-construction condition survey?

A pre-construction site inspection checks that your own site is ready and safe to work on. A pre-construction condition survey, also called a dilapidation survey, records the existing condition of neighbouring buildings and assets so any later damage can be assessed. Many projects need both.

Who should carry out a pre-construction site inspection?

The builder, project manager or site supervisor usually leads it, often with the safety officer. Specialists such as geotechnical engineers, service locators and hazardous materials assessors should be engaged for the items that need their expertise.

Do I need to locate underground services before excavating?

Yes. Get current underground service information, for example through Before You Dig Australia, and have services located and marked on site before excavation. Safe Work Australia’s model Code of Practice: Construction work explains the duty to take reasonable steps to get this information and give it to the people doing the excavation.

Can I do a pre-construction site inspection on a phone?

Yes. In DIGI CLIP, you complete the checklist on a phone or tablet, attach photos to each item and sign off on site. Checklists can be completed without coverage, and anything that needs attention becomes an action in the Action Log.
