Say what? Understanding construction jargon: part 2
If you enjoyed the first instalment of our construction jargon interpretation guide, read on for part 2, which explains more common construction terms.
While diversions can be enjoyable – think checking your Facebook page when you should be preparing for a class – construction diversion works don’t fall into that camp. More like traffic diversions, they involve rerouting of services such as power, water and air-conditioning. Interesting fact: Diverting Building 2’s services has particularly challenging given the number of services – including 20-plus exhaust systems alone – many tied to the rest of campus. Each diversion requires meticulous planning to minimise disruptions.
Floors, levels and storeys
Not much, difference right? Well, yes and no. In construction, the word level is generally used, at least for non-residential buildings, to avoid confusion where there may be more than basement level, for example. Unlike floors and storeys, levels encompass rooftops, which may be used by people or for plant. Interesting fact: The Tower not only has two basement levels (1 and 2) but two ground floors – with level 3 opening to Alumni Green and level 4 to Broadway.
The UTS Tower has more than one basement and ground floor
While the verb form is favoured by Shakespeare (hoist with his own petard) and sailors (hoist the main sail!), the noun is used on construction sites to refer to equipment that lifts or lowers a load using a hook on a rope or chain attached to a drum or lift-wheel. Usually it is operated electrically or pneumatically driven. Interesting fact: Three man and materials hoists will be used on the Building 2 work site, each with a payload capacity of 2400 kilograms, able to carry up to 25 passengers at a speed of 28 metres per minute with a maximum lifting height of 150 metres.
Let’s dive deep for an explanation of this one, which some may have heard about in connection with Building 2. The snorkel, which brings fresh air into a building, is a critical consideration for larger buildings, where its location must be at a distance from where any fumes are vented. Interesting fact: The word ‘snorkel’ derives from the word for the airshaft on German submarines in World War II, which in turn is based on the word for snoring – schnarchen.
It may sound a little risqué, but the process of stripping out internal structural elements from a building prior to demolition usually requires being fully clothed in steel-capped boots, hi-vis vest, hard hat and other protective gear (known as PPE). Interesting fact: Ninety percent of the structual demolition waste from Building 2 is being recycled, including all the concrete, brick and a whole lot of steel from the concrete reinforcing.
