High safety level for the construction of an oil sand refinery in Canada
The PERI UP scaffolding system along with the integration of 3D scaffold planning at an early stage has reduced the time and cost factor while simultaneously increasing safety levels for the construction of an industrial plant in Canada.
North-east of Edmonton/Alberta, the world's most advanced oil sand refinery - the Northwest Redwater Project - is currently being constructed. The facility will produce 150,000 barrels per day, i.e. close to 2.5 million litres of oil. Since 2013, plant components have been installed on the 2 km² area, and the first of a total of three sections will become operational in the autumn of 2017.
Industrial construction without accidents
PERI's North American scaffolding specialists are planning and providing PERI UP industrial scaffold solutions as well as ensuring the on-time availability of correspondingly large quantities of materials. 1,500 t of scaffolding is in daily use while around 1,500 people are employed on the construction site at peak times. For the industrial construction company Fluor, safety is of course paramount: one of the main goals of all project participants is to reach 1 million working hours without any accidents.
High safety levels – increased efficiency
For this, PERI UP provides system-integrated advantages not only during scaffold assembly operations but also when the scaffolding is being used. For example, due to the continuous metric scaffold grid of the PERI UP Flex Industrial Scaffold System, scaffolding installation to accommodate plant components can be systematically and flexibly carried out, i.e. without time-consuming on-site tube and coupling assembly, in 25 cm increments and thus form safe working platforms. Moreover, the consistent use of system components not only accelerates the assembly work on the scaffold. Through the gap-free installation with system decking, this means there are no overlapping planks thus avoiding the presence of any tripping hazards during later use.
In addition to the system-related assembly and safety advantages provided by the PERI UP Flex Industrial Scaffold, the competent on-site project support in particular has been an important factor for realizing time and cost reductions. Furthermore, the detailed 3D scaffold planning as well as the early consultation and coordination with all project participants has increased both work safety and efficiency. The on-site scaffolding planning with PERI CAD enables PERI's Canadian engineers to coordinate the proposed solutions in advance with the project partners. Hence, any problem areas can be identified at an early stage which allows the working scaffold to be optimized for expanded use. This avoids improvisation during the actual scaffolding erection phase thus accelerating working operations and increasing safety levels. In addition, material and transport costs are reduced because only those materials required are delivered resulting in an increase in utilization.
From 3D to 5D
For the industrial project in Edmonton, those responsible are saying that 5D planning is actually more appropriate: the three-dimensional scaffold planning has been extended through additional process data that goes far beyond just the technical solution. Other factors such as material costs, workloads as well as erection time and service life are integrated in the planning process and the scaffold is allocated to individual sections which can be identified at any time. As a result, the project management team can maintain an overview – also for large-scale projects – whereby planned/actual comparisons show possible deviations in the execution compared to the actual planning.
