Frequently asked questions: Civil construction

What happens during civil construction?

Civil construction includes removing any unusable soil and laying the pipes for sewage and storm water and roads. The water supply is connected and cables are laid for utilities such as power and phone lines. At this stage, roads and access ways are also built, including curbing, footpaths and retaining walls.

How long will it take?

The timeframe depends on the site and factors such as weather, however civil construction usually takes about 9-12 months.

What are the hours of work?

Resource consents specify when construction work can happen. This is usually 7.30am - 6pm from Monday to Friday, and 7.30am - 4pm on Saturdays, depending on the construction activity.

Why does the top layer of soil need to be removed?

Topsoil needs to be removed from all the development sites to build houses, paths and driveways on solid ground. Sometimes, areas of topsoil on a site can be contaminated with asbestos, heavy metals and other contaminants, usually because of historical activities such as the original house construction in the 1950s/1960s and house maintenance since then.

All sites are investigated for contamination by an independent and suitably qualified specialist prior to any soil being removed from site.

What happens if contaminated soil needs to be removed?

If testing shows that soil is contaminated, an independent company assesses how much soil needs to be removed and advises us. The soil is then removed by certified professionals to an approved disposal location such as a landfill.

Once the soil is removed, the site is checked by an independent company as part of a validation process to confirm that all contaminated soil has been removed and that the site is clean before we continue with earthworks and construction activities.

What assurances can you give for my safety when removing contaminated soil?

We take every precaution to prevent the release of contaminated material, including asbestos dust, when removing contaminated soil. This includes using licenced asbestos removal organisations, supervision of the works by qualified and experienced environmental professionals, fencing off sites, minimising breakage of asbestos during removal, keeping the asbestos/soil damp during removal, and ensuring asbestos contaminated material is wrapped in plastic before being removed from site.

For more information, please read the Asbestos FAQs.

How do you manage dust and dirt?

Our contractors have a dust minimisation strategy. This often involves hosing down the site to help prevent excess dust spreading across the neighbourhood. At certain times of the year TRC will also arrange for a company to wash the houses that become dirty due to the construction works.

Will this impact traffic and parking?

TRC will also work with the relevant contractors to ensure minimal disruption to parking and traffic movement during the construction works. Occasionally, roads, footpaths and berms may need to be closed for a short time. Before this happens, a traffic management plan must be approved by Auckland Council.

Will it be noisy?

The contractors will do their best to keep any disturbance to a minimum, however you may experience some vibrations and noise during civil construction. Please contact your Neighbourhood Liaison Advisor if you have construction-related noise complaints

How could construction affect my house?

Occasionally, you may notice some vibration from construction activities. We have strict construction and traffic management plans which are designed to minimise the effects of vibration on any nearby homes.
Some houses can be more sensitive to vibration than others due to their age, construction type and where they are located. There is a small chance that vibration may result in minor damage (such as cracks in paint and plaster) to neighbouring houses. If this happens, TRC will repair any damage caused to the property.

To ensure that all neighbouring properties are protected during the development process, TRC offers property condition surveys for houses bordering construction sites.

Who do I contact if I have any questions or concerns?

Please contact our Neighbourhood Liaison Coordinator, Caroline Koloamatangi, on 027 560 8387 with any enquires about the regeneration programme or the development process.

Before construction starts, we will also ensure the Site Manager’s details are also provided to residents.
