\"hub1mar14\"<\/a>One of the UK\u2019s fastest growing parcel firms is constructing a new \u00a3100M facility in the East Midlands.<\/h4>\n

<\/strong>DPD UK parcel hub, Hinckley<\/strong>
\nMain client:<\/strong> DPD UK
\nArchitect:<\/strong> Stephen George & Partners
\nMain contractor:<\/strong> Winvic Construction
\nStructural engineer:<\/strong> Cameron Darroch Associates
\nSteelwork contractor:<\/strong> Caunton Engineering
\nSteel tonnage:<\/strong> \u00a32,300t<\/span><\/p>\n

Due to ever increasing demand for its services, UK and International parcel delivery provider DPD UK is building its fourth and largest hub in the United Kingdom.<\/p>\n

The company currently has three large main parcel sortation hubs at Smethwick and Oldbury in the West Midlands, locations that are conveniently located in the centre of the country with easy access to the M6 motorway.<\/p>\n

The new facility at Hinckley also has good motorway access and should be fully operational by 2015. It will create up to 1,000 jobs, increasing DPD\u2019s overnight parcel sorting capacity by as much as 65%.<\/p>\n

The structure is huge and measures 480m long \u00d7 40m wide. Internally it has a 30m wide clear span, formed by a series of tapered lattice trusses that have a maximum depth of 5m. The trusses are important, not just forming the roof, but also supporting a steel grillage that will in turn support the hub\u2019s conveyor system.<\/p>\n

In most similar installations the conveyor would be supported off the ground floor slab by an extensive system of support frames provided by the conveyor supplier. This format significantly reduces the clear circulation routes and operating efficiency of a facility.<\/p>\n

\u201cTo avoid this the client required us to design the building frame to support the conveyors without the need for internal supports. It is believed that the company\u2019s Hub 3 and this new Hub 4 are the only such facilities in Europe to be designed in this manner,\u201d says Neil Darroch, Cameron Darroch Associates Project Engineer.<\/p>\n

\u201cIn effect the client has paid an initial premium for the building to maximise long term operational efficiencies. Steel was the only feasible option to allow us to meet the client\u2019s brief.\u201d<\/p>\n

The structural steel frame of the hub is based around 72 \u00d7 6.35m wide bays, with each bay large enough to accommodate four loading doors \u2013 two on each side of the building. Stability is derived from the portal action within the trusses and bracing located in some bays.<\/p>\n

The steel grillage hung from the trusses is not based on the standard grid pattern. These columns are mostly set off grid and were all designed with the conveyor system in mind.<\/p>\n

\u201cThe steelwork can\u2019t interfere with the building\u2019s all important conveyors or any internal traffic movements,\u201d explains Mr Darroch. \u201cConsequently the hanging columns are all set at various points so as not to clash with any of the sortation plant.\u201d<\/p>\n

Aside from the main sorting area of the hub, the remainder of the structure\u2019s width is formed by a series of 10m long rafters that share a row of internal columns for support. The rafters support the roof over a two-storey office mezzanine that extends throughout the 305m long central portion of the hub, while either side of this shallower lattice girders support single-storey timber decked mezzanine floors required for the parcel in-feed areas.<\/p>\n

The timber areas required steelwork contractor Caunton Engineering to erect a system of cold rolled C-sections, spanning between hot rolled primary beams suspended from lattice girders forming the roofs. The office mezzanine levels are constructed with a more traditional composite steel beam and steel flooring configuration.<\/p>\n

\u201cBecause of the overall length, we divided the building into four phases for our erection programme,\u201d says Bob Aitman, Caunton\u2019s Erection Manager. \u201cUsing two mobile cranes we erected two trusses and their columns, then in-filled the hanging steelwork and then installed the connecting rafters and mezzanine sections. We would then repeat this format until each phase was completed.\u201d<\/p>\n

Apart from the trusses, which arrived on-site in two pieces, all of the steelwork for this project was immediately ready for erection once it was delivered.<\/p>\n

By working its way systematically down the structure, Caunton was able to leave a completed frame ready for follow-on trades to get started as quickly as possible.<\/p>\n

The latest DPD UK hub at Hinckley forms part of a new business park being developed by Goodman. As well as the main building, the hub also consists of four other structures, all of which are formed with steelwork.<\/p>\n

A four-storey gatehouse, with a footprint of 20m x 37m, is the largest of these structures. Constructed around a standard beam and column grid the building will accommodate three floors for security, offices, a canteen and staff welfare facilities, with the top level used for plant equipment.<\/p>\n

The other on-site structures consist of a portal framed vehicle maintenance unit with attached offices, a garage\/tyre store and salt barn building, and a vehicle jet washing facility.<\/p>\n","protected":false},"excerpt":{"rendered":"
