The Brief
We were engaged by consultants working with the Ministry of Education (MoE) to assist with a ground gas assessment and evaluation of risk posed by a former landfill at the site. The Ministry was in the preliminary design stages for the redevelopment of Te Kura Kaupapa Māori o Te Whānau Tahi, which included the demolition of a number of school buildings and construction of their replacements.
What We Did
Following a peer review of existing data and an assessment of ground gas risk, we completed further gas monitoring on site to help evaluate gas migration through the soil profile. This included gas flux box monitoring at multiple locations within the proposed building footprint, in accordance with overseas gas monitoring guidance.
On completion of the additional monitoring, we provided initial gas mitigation recommendations to the design team and structural engineers.
Following our involvement with the ground gas risk assessment, we were retained to provide planning services and obtain the necessary regional council consents for the proposed school development. Due to the presence of landfill waste on site and the required earthworks, this included assessments of effects on stormwater, groundwater and air quality during the construction programme.
