Dunbar and Boardman have worked on many new construction projects over the years. Construction projects are becoming ever more complicated. This is partially due to the complexity of plans for many buildings but also as a result of new standards for sustainability and best practice. For example, the UK has some of the most ambitious targets in world for so called ‘zero carbon’ standards. The architectural community in the worldwide has embraced architecture that minimises the negative environmental impact of buildings by efficiency, choice of building materials and regulation of energy consumption.
This focus has led to the successful completion of low energy buildings such as The Green Building in Manchester City Centre. Vertical transportation is just as important as sustainability in deciding the potential success of a building. All successful buildings must be able to transport people and goods efficiently. Vertical transportation systems usually account for between 2-7% of a building’s energy consumption.
The client challenged the design team to reduce the carbon footprint of the building and utilise production techniques that could also reduce the site programme or construction costs. Historically, lift shafts have been formed from block work or steel frames; in recent years where there has been good site access, modular pre-cast concrete has been utilised to form the shaft enclosures.
The use of a Glulam structure reduces the carbon footprint of the building and speeds up the construction process, as the structural elements are manufactured off site and delivered flat pack style. The wall assemblies are then bolted together on site to form the shaft structure above the pit area.
The use of a Glulam structure (Glued laminated timber) reduced the carbon footprint of the building and shortened the construction process. The structural elements were manufactured off site and delivered flat pack style. Glulam is a type of structural timber product comprising a number of layers of dimensioned timber bonded together with durable, moisture-resistant structural adhesives. By laminating a number of smaller pieces of timber, a single large, strong, structural member is manufactured from smaller pieces. The wall assemblies are then bolted together on site to form the shaft structure above the pit area. The structure was designed and manufactured by Lilliheden who have a UK base in Barnsley.
