4 1.2 The full specification and drawings for the materials and components covered by this Certificate have been examined and are retained by the BBA. This section gives only general details of the system. 1.3 Each volumetric module is factory built and consists of a structural steel framework, an insulated floor, an insulated ceiling/roof structure, and insulated wall cladding on external walls. Structural steel framework 1.4 The steel structure is manufactured from bolted and/or welded hot rolled steel members. The structure incorporates perimeter floor beams and roof beams, corner columns, internal structural steel members (including, if required, lateral cross-bracing), forklift pockets and lifting eye connections. The steelwork is grade S275 and protected with a two-pack epoxy zinc phosphate primer and a single pack Firetex FX2002 intumescent paint finish. All internal columns and posts are encased with plastisol coated steel and mineral wool insulation between the member and the casing. Insulated floor 1.5 Floors/intermediate floors comprise pairs of 220 mm deep by 65 mm SwageBeam cold-worked galvanized steel joists, grade S390 (2.0 mm or 2.4 mm thick), fixed back to back and at 400 mm centres span between the primary beams. A 2 mm thick profiled steel plate is screwed to the underside of the joists and 200 mm mineral wool insulation (maximum λ 90/90 value of W m 1 K 1 ) filled between them. Engineered plywood tongue and groove boards, 25 mm thick, are fixed to the joists with TEK screws and neoprene tape. The floor is finished with 2 mm thick fully welded static dissipative floor covering complying with EN ISO : Insulated ceiling/roof structure 1.6 The roof/ceiling stucture comprise 100 mm by 60 mm hot-rolled rectangular hollow section at nominal 1200 mm centres are connected to both roof perimeter beams and provide support via a continuous ledger plate for 100 mm thick Isoclad Firestop 12 composite panels. The facings to the panels are of 1.5 mm galvanized steel with a plastisol finish on the exposed faces. The sloping flat roof consists of Powerdeck F tapered insulation system comprising rigid polyisocyanurate (PIR) foam board (maximum λ 90/90 value of W m 1 K 1 ) with thicknesses varying from 220 mm to 40 mm to provide a 1 in 80 fall to the insulated galvanized steel gutter incorporating a roof outlet. Each board is mechanically fastened using a minimum of four (1) TKR diameter Ejot fixings with Ejot HTK Plastic extension sleeves. A 1.5 mm thick Rhepanol polymeric roof membrane weatherproofing system (covered by BBA Certificate 02/3922) is bonded to the Powerdeck and trimmed with appropriate flashings and seals to complete the roof construction. (1) The number of fixings to be determined on a case-by-case basis as specified by the design Engineer. External walls 1.7 The external walls are formed from Isoclad Firestop 12 composite wall panels spanning horizontally between supports. On end panels supports are corner columns at 4500 mm centres and for gable walls, corner columns, intermediate posts and gable posts are provided at a maximum of 3800 mm centres. The gable posts are constructed from two cold formed profiles creating a 150 mm by 150 mm by 2 mm thick box section. The posts are secured to the main perimeter frame with bolts through brackets incorporating slotted holes to ensure no vertical load is transferred from the perimeter beams to the gable posts. The panels are third-party approved (against LPC 1208: Issue 2) and comprise steel faces bonded to a mineral fibre core (maximum λ 90/90 value of W m 1 K 1 ). The facings to the panels are of 0.7 mm galvanized steel with a plastisol finish on the exposed faces. Additional structural supports are provided adjacent to each opening. 1.8 Fixings, sealants and trims supplied by the Certificate holder to specifications agreed with the BBA. 2 Manufacture 2.1 The modules are fabricated by the Certificate holder. The steel framework is constructed by bolting and welding. The roof, floor and wall panels are made up separately and assembled to the framework. 2.2 As part of the assessment and ongoing surveillance of product quality, the BBA has: agreed with the manufacturer the quality control procedures and product testing to be undertaken assessed and agreed the quality control operated over batches of incoming materials monitored the production process and verified that it is in accordance with the documented process evaluated the process for management of non-conformities checked that equipment has been properly tested and calibrated undertaken to carry out the above measures on a regular basis through a surveillance process, to verify that the specifications and quality control operated by the manufacturer are being maintained. 3 Delivery and site handling 3.1 Each module is transported on a flat-bed lorry or trailer long enough to fully support the structure. The Air Optimiser module weighs approximately 30 tonnes and the Power Management and IT Room modules weigh 23 tonnes each. During transport, the modules are covered to protect against weather. 3.2 The individual modules are sufficiently robust to be lifted, transported and sited and are unloaded by crane via a proprietary M36 lifting eye bolted into the head of each intermediate prop position via a captive nut. The safe working load for the lifting eye connections is 10 metric tonnes each and the forklift pockets are 30 metric tonnes combined. 3.3 The modules are normally positioned on the day of delivery and the assembly is carried out by the Certificate holder s operatives, thus site storage is not required.

5 Assessment and Technical Investigations The following part of the Certificate gives a summary of the assessment and technical investigations carried out on BladeRoom Modular Data Centres. Design Considerations 4 Use BladeRoom Modular Data Centres, typically consisting of three to eleven modules have been assessed for structural stability up to two storeys, for use inside an existing building shell or as an external building within the restrictions defined in section 6. Specifiers must ensure that; plan form, internal subdivision, siting, access for the disabled, access for fire services, and means of escape in case of fire, comply with the relevant requirements of the Building Regulations. 5 Practicability of installation The Data Centres are installed by the Certificate holder s operatives who are responsible for delivery, installation and commissioning. 6 Strength and stability 6.1 BladeRoom modules and the connections between modules have been designed in accordance with BS EN : 2005 and BS EN : 2006 to resist the actions resulting from: self weight and imposed loads given in BS EN : 2002 National Annex to BS EN : 2002 snow load given in BS EN : 2003 National Annex to EN : 2003 wind load given in BS EN : 2005 National Annex to EN : The structural stability of the individual modules is based on the worst case loading for a two storey application defined as follows: Floor Loads maximum line load from computer rows (1) ; at ground floor level = 12 kn m 1 at first floor level (2) = 10 kn m 1 maximum aisle areas load = 3 kn m 2 temporary concentrated load (3) = 10 kn (1) Loads on modules used for air optimisation or plant rooms are less onerous. (2) With a maximum of two rows of computer racks per module. (3) Including resistance to a acting through a 100 mm by 100 mm loading plate (equivalent UDL over the whole area 7.7 kn m 2 ). Roof loads roof load (4) = kn m 2 roof imposed actions snow = kn m 2 roof wind pressure (5) = kn m 2 roof wind suction (5) = kn m 2 roof plant (6) = 3 kn m 2 ceiling load = kn m 2 (4) Imposed load applies to locations where access is not provided, other than that necessary for cleaning or repair. (5) Modules designed for up to two storey applications only, covering UK mainland sites with: a basic wind speed up to 25.5 m s 1 as defined in BS EN : 2002 covering the line drawn approximately between Glasgow and Aberdeen on Figure NA.1 within the UK NAD to BS EN : 2002 maximum site altitiude100 m altitude above sea level, and not located in areas of severe wind exposure, e.g. top of escarpments building taken to be 50 km from the coast, except where the nearest coastline is the East coast of the UK. In this situation the distance to the coast is reduced to 5 km. (6) Roof-top mounted Air Handling Units: maximum 2 pairs of condensers per module. External Wall Loads worst case wind action (5)(7) = kn m 2. (7) When subjected to the wind loads referred to above, calculations indicate that a minimum number of four linked modules are required. Cross bracing is required in one of the 4.5 by 3.75 end panels of each non-gable elevation. Note: For more onerous applications site specific designs by a suitably qualified engineer will be required. 6.3 The sub-structure on which the modules are sited must be designed to withstand the maximum load to the foundation. The maximum loads for a two-storey Data Centre are shown in Table 1. The foundation loads for each Data Centre will be provided by the Certificate holder. The loads may be reduced by the addition of extra supports for each modules perimeter beams (details available from the Certificate holder). Page 5 of 12

Members that are exposed are coated with intumescent paint to achieve a 60 minute fire protection in accordance with BS : 1987, BS : 1987 and BS EN : The steel face surface provides a class 0 spread of flame. 7.3 The Isoclad firestop12 panels that form part of the external wall construction and ceiling, incorporate Plastisol coated steel panels with a class 0 spread of flame and have accreditation against LPC 1208 : Issue 2. When fire resistance is required: detailing should be in accordance with LPC Certificate 142a, or determined by test from a UKAS accredited laboratory. 7.4 Where it is necessary for fittings, services or ducts to penetrate part of the fire-resisting construction, the detailing must ensure that the relevant fire resistance is not impaired, particularly in relation to the integrity requirements. 7.5 Where it is necessary to meet Building Regulations, the concealed space between the ground floor ceiling and first floor must incorporate adequate fireproof barriers to prevent the unseen spread of smoke and fire. 7.6 BladeRoom Modular Data Centres are provided with a fire suppression system that is outside the scope of this Certificate. 8 Thermal performance 8.1 The U values given below exceed the default values in Building Regulations. Designers must ensure that Data Centres achieve the target carbon emissions reduction for the complete proposed building when compared to the notional building. 8.2 For the purpose of calculations, the element U values may be taken from Table 2.

(4) For a floor perimeter-to-area ratio (P/A) of approximately 0.28 for the smallest unit. (5) For a floor perimeter-to-area ratio (P/A) of approximately 0.17 for the largest unit. 9 Condensation 9.1 The air temperature and humidity within the modules are controlled by equipment outside the scope of this Certificate. Interstitial condensation 9.2 When the modules (wall panels, ceiling panels, flooring and flashing) are appropriately sealed against the ingress of water vapour, interstitial condensation will not form within the construction. 10 Weathertightness and damp-proofing 10.1 The steel supporting columns raise the modules clear off the ground, giving it an inherent resistance to ground moisture. A damp-proof course (dpc) to protect the galvanizing is required where the steel structure is in contact with the foundations Where relevant, in preparing the site for erection of the BladeRoom Modular Data Centres, adequate drainage must be provided to prevent water collecting beneath or against the structure The roof and external wall surfaces provide adequate weather resistance when installed in accordance with the Certificate holder s instructions. The final weathertightness of the Data Centre is dependent upon correct positioning and sealing of the welded roofing membrane, flashings, gutter/gutter outlets and joints between modules The performance of windows and doors is not covered by this Certificate. 11 Services Electrical and plumbing services are outside the scope of this Certificate. However, in designing and installing these services, precautions must be taken to avoid the possible risk of long-term damage to the module structure or the services by, for example, the ingress of water, water vapour or condensate. 12 Maintenance and repair 12.1 Where used, gutters and downpipes must be inspected regularly and blockages cleared Site-applied seals should be checked as part of the maintenance regime for the structure. The seals should be replaced when required The roof covering should be inspected at regular intervals External surfaces of the wall panels require an occasional washing down with water containing a mild detergent. Where a high aesthetic standard is required, maintenance painting may be required after a period of between 10 and 30 years, depending on colour and environmental conditions, using a paint recommended by the Certificate holder In the event of impact or other damage to an external wall, a replacement panel must be installed by the Certificate holder The ceiling and internal wall surfaces can be cleaned using water containing a mild detergent. These surfaces can be decorated using a paint recommended by the Certificate holder Should it be necessary to replace or repair the floor covering, all joints must be adequately sealed and welded. Any replacement floor covering must be to an equivalent specification as that of the original. Page 7 of 12

8 12.8 The maintenance of the electrical equipment and other hardware used within the Data Centre is outside the scope of the Certificate (1). (1) For further information, the advice of the Certificate holder should be sought. 13 Durability 13.1 The main structural framework is assessed as capable of achieving a design life of 60 years. Other elements can achieve a design life of between 25 and 60 years depending on the materials, construction and degree of maintenance (1). (1) Reference may be made to BS 7543 : 2003, or a relevant Agrément Certificate in this respect Particular care is required in arrangement for damp-proof courses, integrity of joints between wall panels and weathertightness of the building envelope Foot traffic over the roof should be restricted to the purpose of maintenance and suitable precautions taken to avoid the risk of damaging the roof membrane The roof and floor coverings may require replacement during the building s life. 14 Re-use and recyclability The main structural components can be re-used. Installation 15 General 15.1 Erection of the BladeRoom Modular Data Centres is carried out solely by operatives approved by the Certificate holder Due to the size of the modules, it is necessary to plan with respect to access, obstructions and the logistics of using large machinery and equipment required for the installation process. Consideration must also be given to site boundaries and compliance with Building Regulations (see section 7.1) All necessary health and safety procedures must be observed and strictly adhered to. 16 Preparation 16.1 All pre-installation site surveys, checks and considerations must be taken into account, particularly with regard to suitable foundations and drainage and service provisions It is essential to set out level and accurate foundations and service connections and these should be supervised and accurately checked before the system modules are delivered to site. The foundations must be built in accordance with the Certificate holder s design. 17 Procedure 17.1 The modules are placed by crane by the Certificate holder on prepared foundations using purpose-designed lifting points incorporated in the steel frame The modules have protective weatherproofing coverings that are removed prior to lifting and installation into position The foundation connection bar rods for each corner foundation connector and locator plate are installed into the oversized (±25 mm) pre cast or drilled holes within the foundations to allow for structural movement (see Figure 2). Structural galvanized steel levelling shims (25 mm thick) are inserted as appropriate, enabling mortar infill to be applied after unit installation Alternatively, Hilti M16 stud anchor bolts or equivalent can be used to secure the foundation connector locator plates and are fully tightened once the modular units have been bolted together. Figure 2 Foundation locator plate detail Page 8 of 12

9 17.5 The Bladeroom modular unit is fastened using four M bolts at each corner connection and locator plates and six M bolts at module-to-module foundation connection and locator plates. This process is repeated until all units are secured to the module-to-module and corner connecting foundation plates Once all the modules have been securely situated and correctly aligned in the foundation connection and locator plates, the module shoes are then fully tightened to the foundation plate. Any gaps beneath the corner locator plate must be filled with a suitable grout as specified by the Certificate holder. Module-to-module joints Walls 17.7 Before adjacent modules are sealed, additional mineral wool insulation and expanding foam tape is installed between the exposed module posts. The cavity between the modular units is filled with 150 mm deep insulation to the full height of the cavity. Expanding foam tape is applied to full height, floor to ceiling of the external wall to provide a weathertight and airtight seal. The process is completed on the internal wall to encase the insulation securely. Each module connecting post can then be bolted together using the predrilled holes using M mm bolts. Roofs 17.8 On the roof, the bay-to-bay junction of the Rhepanol roof lining membrane must be weather sealed. Overlapped joints and detailing must be clean and dry prior to sealing. A solvent welding agent is necessary in moist and cool weather or where significant dirt has built up. The external weather seal is formed by applying cover tape across the module bay-to-bay joint in accordance with the membrane manufacturer s instructions. Floors 17.9 The internal joint gap between the modules is filled with PVA adhesive and a plywood insertion is cut to fit the gap and secured with screws at 300 mm centres through the plywood and steel floor beam Data Centre modules of the same length can be stacked (see section 6.3). The modules are bolted together at steel column points and along the longitudinal beams On the Air Optimiser module, the plant deck and DX condensing unit and interconnecting pipework are fitted after the installation of the modules. Finishing The completion of external and internal cladding and trims is carried out on site by the Certificate holder. Service connections are made and internal subdivisions and finishes completed at joints between modules. Technical Investigations 18 Investigations 18.1 An analysis was made of data to determine: structural adequacy roof and wall U values to BS EN ISO 6946 : 2007 floor U values to BS EN ISO : An examination was made of existing data to assess: behaviour in fire impact resistance of floor and wall panels load capacity of roof and floor weathertightness durability maintenance requirements The manufacturing process was examined, including the methods adopted for quality control, and details were obtained of the quality and composition of the materials used.
