Pokeno Sports Park Earthworks and Carpark Project

This project was for bulk earthworks and carpark construction. It required construction services to complete the final stage of the site works for the Pokeno Sports Park development. The works involve topsoil stripping and respread, the minor site cut to fill, importation of 34,000m3 of structurally certified cut to fill, geotechnical treatments inclusive of gravel rafts and underfill drainage and accessway and carpark construction. We were originally unsuccessful at the tender stage because of not having our SHE PreQual at submission (now obtained). However, WDC preferred our methodology to use local stockpile waste from a neighbouring factory to save on costs and the local environment by reducing carbon emissions and waste pollution. WDC requested the winning tenderer to subcontract the work to Midgley because of this out-of-the-box creative solution.

Our role as a subcontractor was to install the environmental controls and supply 90% of the fill requirement. Because the requirement was for a 34,000m3 stockpile, there would be a large amount of traffic movement required to get that delivered from the local quarry; instead, we collaborated with the neighbouring factory to use their unused stockpile to fill the gully. We used a 50t digger and supplied five trucks and trailers on turnaround from the dairy factory 2.5km away. It would have needed around 10 to 15 trucks and trailers to supply from other resources.

Like TDC EUL, this Pokeno earthworks project required experience and expertise with a technically challenged bulk earthworks project. There were several truck movements and a need to keep the job clean and tidy and work with local residents to ensure limited disruption and no hazards or risks. The workmanship was of the highest standard, with works in very close proximity to the factory and residential areas. Careful planning and daily engagement with all stakeholders enabled has been key to this successful delivery.

Dust control was a key concern with the large amount of traffic movement near the local dairy factory. Toolbox talks were more important to ensure we educated our team on the importance of dust control; there could be no dust spreading into the diary factor. Daily communications with the Operations Manager advised us whether the wind was blowing in the right direction or not. A water cart is required for the duration of this project. We had to also deal with working in bad weather conditions because the client pushed out the start date. This meant we could not complete it within the Earthworks season and had to get special permission for an extension to complete the work.
