Client: Christchurch City Council

Project: 31 Nayland St.

Job Type: Asbestos Removal, Contaminated Land Remediation

Estimated Duration: 6 Weeks

Description:

Scope was appointed to undertake asbestos removal from the dwelling at 31 Nayland Street for Christchurch City Council. This included roof removal and environmental cleaning within the roof space.
A scaffold was erected as edge protection and the team worked with harnesses in fall arrest due to the steep roof pitch.
Third-party independent air monitoring was running throughout the roof removal to ensure the safety of the neighbours and nearby building sites.
All areas were swab tested and third-party independent validation was undertaken by TriEx Ltd upon completion of removal works.
During the subsequent demolition of the building, further asbestos contamination was uncovered in the soils across the site.
TriEx Ltd took soil samples which indicated that there was a historic widespread asbestos contamination on the site.
We developed strategic methodologies to ensure we maintained Asbestos Health and Safety requirements as well as the most practical and cost-effective result for the client.
We were required to work very closely with TriEX and CCC throughout this project. On going site reporting including details of what was to be undertaken and how the risks were being managed was essential and provided to all neighbours and general public in the area.

Client: Watts & Hughes Construction

Project: Christchurch Wastewater Treatment Plant (CWTP).

Job Type: Asbestos Removal- Bonded Asbestos

Estimated Duration: 10 Weeks

Description:

Scope was appointed to undertake asbestos removal from the roof of a building at Christchurch Waste Water Treatment plant during refurbishment work being carried out by Watts and Hughes. The bitumen membrane that had been applied to the roof contained asbestos which had soaked through to the timber below. Both the framing timber and the bitumen membrane were removed.
Third-party independent air monitoring was running throughout the roof removal process to ensure the safety of both Scope staff and CWTP personnel, as the removal area was fringed by operational areas of the treatment plant.
The roof removal took place in two stages to allow the Water Plant to continue operations during our asbestos removal.
During the subsequent demolition of the building, asbestos -containingh vinyl was identified.
An enclosure was built around and over the various areas of vinyl. Our team worked closely with Watts and Hughes site management to deal with the vinyl swiftly and deliver a fast response to ensure minimal delays to their project.

Client: Airways New Zealand

Project: Airways Control Towers- Rotorua & Palmerston North.

Job Type: Asbestos Removal

Estimated Duration: 2 Weeks

Description:

Scope was appointed to undertake asbestos removal and environmental cleaning for Airways New Zealand. Asbestos containing material was identified in the service riser leading to the control tower cab at both Palmerston North and Rotorua airport sites. We undertook highly friable millboard removal, within secure friable enclosures built by our team prior to removal works.
The Environmental Clean and Asbestos Removal procedure had to be undertaken while the control tower was live. Careful removal methodologies were adopted to ensure no services were disconnected to the control tower cab. Night work was undertaken in fire egress areas to prevent disruption during the daytime running of the tower services.
Operational issues were discussed in detail on a daily basis to avoid any delays for Airways New Zealand
Due to the sensitivity of the riser, Scope used pressure differentials to ensure enclosures on multiple levels were under constant negative pressure during removal works. Real time air monitoring was running throughout the project because of the sensitivity of the environment. All areas were swab tested and air cleared before dismantling the enclosures. Third party independent validation of results was undertaken by TRIEX.
