3775 Draft risk assessment EHU Technology Hub 1. General note This project is for a three storey generic teaching building attached to an existing three storey building known as the Levens. The scheme includes a lecture theatre and a space with a lower floor level for the CAVE (computer augmented virtual environment). There is a single storey building on the site that will be demolished. The site is on the periphery of busy university campus (includes residential) adjacent to a main access that will remain in constant use. The site must be secured at all times. Vehicle movements are in a restricted area with cars/pedestrians and will require planning and careful management The contractor needs to be aware the teaching and examinations are ongoing and will be expected to liaise with the university to minimise disruption. 2. 3. 4. 5. Access No access is permitted via Ruff Lane, all contractor access from St Helens Road. Congestion, St Helens Road and access to the University can be congested at peak times and should be avoided. Applies in particular to delivery of large components eg roof sheets Fire Access Route. The existing road layout incorporates a fire access route across the south end of the site. This would cross the site area and would need to be maintained throughout the duration of the works. Alternative fire access to be reviewed by EHU Adjacent buildings. Will remain is use throughout the duration of the works, The Levens (attached) will remain occupied until the end of June 2016. Services, access and means of escape must be maintained. This will include amending the existing external fire escape to clear the site area and defining the external escape route The site is adjacent to a residential area, planning/consideration must be given to keep noise and disruption to a minimum and avoid extended working hours when activities may be disruptive The planning approval will probably restrict working hours Services, there are existing underground services plus incoming gas supplies adjacent to the site. Some survey information is available but must be checked prior to any excavation 3775 Draft risk assessment EHU Technology Hub 6. 7. 8. 9. Services in the immediate area of the building will be diverted prior to possession Trees. All trees on the site are protected (TPO) access and handling of steel and components should take account of the restrictions that this imposes Demolition. Not part of this contract Drainage. Covered elsewhere Construction. Three storey steel frame on piled foundations. Part curtain wall enclosure, part SFS or SIPS panel. Although relatively small in area, the roof will include long continuous sheets of standing seam roof on a liner tray. The sheets will include a curved section. Area of lower floor level (future CAVE) on ground floor Main stair. Steel structure, components will require mechanical handling and sequenced with assembly of main frame Re-configuration of existing external steel fire escape The lift in the Levens will be retained. Construction sequence to be considered due to limited access along West side. The east side will include the former car park as hard standing but is still constrained by the tree canopy. 10. 11. 12. Glazing. Glass will require mechanical handling. Limited areas of inclined glass at ground floor level Maintenance. Materials have been chosen to minmise future maintenance. The facades consist of glass, powder coated aluminium and brick and other than cleaning (primarily from ground level) require minimal attention for the lifespan of the material. High level windows (vents to central space) will require infrequent cleaning using a fall arrest system Roof construction is split between single ply membrane and standing seam aluminium, the single ply is generally protected by a green or brown roof. The standing seam roof is virtually maintenance free except for a high level gutter that can be reached using a mobile platform. The continuous sheets reduce the potential of failure but access and assembly requires consideration (a specialist sub contractor has been consulted during design development). 3775 Draft risk assessment EHU Technology Hub Decoration. Access scaffold/towers will be required in the central space. The existing lift in Levens retained with existing access and maintenance regime 13. Services and lighting, detailed elsewhere but the services within the building are minimal. The generic teaching spaces have been designed primarily to rely on natural ventilation with some mechanical assistance. The exceptions being the lecture theatre that has local air handling and cooling and the possible CAVE area that requires cooling. Lighting, largely LED sources with very low maintenance requirements. High level actuators do not require frequent maintenance, specific access arrangements will be needed, eg high level vents in circulation space. 14. Means of escape. The building has been designed in compliance with Pt B of the Building Regulations. Mechanical smoke venting was considered but designed out External works, described elsewhere 15. 16.
