Perfect Concrete Care has just completed a major grinding project at 321 Kent Street, Sydney CBD. The project covered 5 levels of the building.
Dexus Property Group managed it, and previously a law firm occupied it. Each level was 1,500m2, a total of 7,500m2 for the total project. The project had an approximate value of $500,000.
The Challenges
Our concrete care division, involving concrete coring and cutting out penetrations in existing concrete fixtures, undertook detailed demolition works.
The project ran for a total of 5 weeks, with crews of up to 15 men running during day shifts and night shifts. Including the times of the estimating, project management, administrative and site management functions. Over 4,000 man-hours were expended on this project. Due to the large number of resources involved in this project, they employed daily scheduling and monitoring of quality and costs to ensure the project was completed on schedule and on budget.
Perfect Concrete Care is proud that it could complete the project without any safety incidents on site. It shows that efficient work health and safety policies and procedures are implemented to ensure the safety of all workers on site. There were also no reported incidents of near misses on site.
The tasks in the demolition strip out involved carefully dismantling workstations, removing ceiling tiles and grid, and removal of all floor finishes. It also involved the removal of air conditioning ducting, kitchen joinery, doors, and detailed demolition work to make good. Variation works were gained through the need to make good the exposed concrete slab, where the Perfect Concrete Care division was engaged to undertake concrete grinding of the complete 7,500m2 area. All floor grinding works were completed after hours, so as to not disturb occupants on other levels.
A major component of the overall project was managing waste generated from the project. A customized waste management plan was developed to recycle and reuse as much waste material as possible. This included the recycling and reuse of gyprock, workstations, joinery, and appliances. It also included kitchen cabinetry, steel, aluminum, timber, and various other materials.
