Surespan

ProjectSurespan designed and manufactured a series of roof access hatch for the New Data Centre in Singapore.The data centre was budgeted at $30 million SGD and covers an area of 269,000 sq ft. The roof hatches were used as key access locations for maintenance and repair of the 8 cooling towers installed at roof level supplying up to 1000 watts of cooling per sq m.ProductsThe series of roof hatches featured a 900 x 900 opening and in the interest of security, the hatches were supplied with an internal cablock which can only be opened from the inside and safety hold open stay to prevent accidental closure.

Product:Surespan manufactured this SAC Aluminium, single leaf, flush floor access cover to fit a structural opening 1000 x 1000mm. The access cover comes complete with gas spring assisted, Aluminium chequer plate lid which locks in the open position with a safety hold open stay to prevent against accidental closure. Should any water pass the seals, it will be dispersed via an integral drainage channel. The lid is held shut by a heavy-duty Grade 316 Stainless Steel ‘slam action’ cab lock and can open from both sides with the use of a removable ‘Tee’ key., for safety. Finished Self-colour Aluminium.

IntroductionFerrari World in Abu Dhabi is the world's first Ferrari theme park. The park includes 37 different rides and attractions and features the world's fastest rollercoaster “Formula Rossa” – reaching 240 km/h in 4.9 seconds. The park has been open since 2010 and has been nominated for numerous awards. Project:Ferrari World in Abu Dhabi needed a unique solution to allow for the maintenance of rollercoaster carts. Due to restricted space, a sliding hatch was proposed to allow easy craning in and out.Products Supplied Surespan manufactured and supplied an SLHE Aluminium, thermally broken, single leaf, electrically operated, sliding roof access hatch. The hatch was a large 5400 x 4000 structural opening sliding hatch.A sliding hatch allowed maximum clear space. Operated by a 230v geared motor. The lid and upstand are filled with 50mm thick CFC and HCFC free Polyisocyanurate insulation which offers a U-Value of 0.43W/m²K.

IntroductionSurespan designed and manufactured the highest hatch in the world, a 600mm diameter submarine access hatch located 816 meters up on the Burj Khalifa. The Burj Khalifa is the world’s tallest building, soaring 828 meters above Dubai. The design for the 162-story tower combines local cultural influences with cutting-edge technology to achieve high performance in an extreme desert climate.Products suppliedWe supplied;Surespan was selected for its engineering expertise, innovative designs, and unique skills.The team designed and manufactured a 600mm diameter, polish grade 316 stainless steel simulated submarine access hatch with handwheels. The hatch is located at 816 meters and is used for maintenance access to the aircraft warning lights.The projectAs part of the 1.5-billion-dollar mega Downtown Dubai project, the government of Dubai decided to build the world’s tallest building. This project redefines what is possible in the design and engineering of supertall buildings.  Architect firm Skidmore, Owings & Merrill design inspiration for the tower was taken from the shape of a regional desert flower the Hymenocallis, also known as the desert lily and the patterning systems embodied in Islamic architecture.

Kielder Observatory Surespan designed and manufactured two sets of bespoke double leaf hatch doors for the Kielder Observatory located in England’s largest forest in Northumberland.  The ProjectAs part of the Kielder Art and Architecture program, Charles Barclay Architects designed Kielder Observatory for the Forestry Commission. The all-timber observatory was constructed from Douglas fir with larch cladding, the pier-like building has rotating turrets that house two permanent telescopes and an observation deck. The turrets can be rotated through 360 degrees.The observatory generates its energy using a wind turbine and photovoltaic panels and includes a composting toilet. The observatory has received 2009 awards from the RIBA and The Civic Trust and featured in the inaugural World Architecture Festival.  The ProductSurespan design and manufactured two sets of bespoke double leaf hatch doors for the roof and the front of the Observatory’s two rotating turrets – one to house a 20” Pulsar manual telescope and the other for a small Mead 14” telescope.  FeaturesThese hatches are electrically operated and have been specially designed to open in a specific sequence using remote control via 24v dc actuators.      

The new thermally broken sliding roof hatch opens horizontally on fixed or telescopic rails. The hatch features the following key points: Thermally Broken Lid & Upstand Fixed or Telescopic Rails ‘Lift-Off’ Unseated Opening, ensures the hatch is sealed and secure when closed. Self Sealing Double Seals 0.43 W/m²K U-value Perfect for manual operation, the sliding cover easily and smoothly opens. Brush seals around the front and side ensure that no roof debris can interfere with the mechanism and the external fixed rail provides enhanced support for larger sliding covers.

Surespan designed and installed four revolutionary new hatches inside the Fore Street tunnel on the A406 North Circular Road in Edmonton, London. The hatches are the first of their kind in the UK and have been specifically designed for Transport for London to not only withstand the weight of major volumes of traffic but also allow safe and easy access to the wells beneath.They are currently being trialled in Fore Street tunnel for 12 months. Made of aluminium, they are capable of withstanding D400 loading yet can be easily opened by one operative.

Surespan manufactured this HIACE/GWO aluminium, single leaf, flush floor access hatch for a company in London to fit a structural opening 2600 x 650mm, recessed with TripleLite ‘Walk-on-glass’ infill. The lid is operated by two 24v DC actuators. The TripleLite 34mm thick glass suits pedestrian domestic loading only. The patent frame with unique hidden hinges incorporates an EPDM unbroken seal to help prevent the ingress of dirt and moisture. This access cover is not watertight, it is self-draining. Should any water pass the seals it will be dispersed via an integral drainage channel.
