  12. Blocks B & C - Material Treatment  Blue engineering brick at ground and first floor of all blocks  White acrylic render to upper floors of Blocks B, C & D with projecting frame detail linking bedroom windows.  Lounge bay window projections of dark grey metallic metal cladding incorporating coloured aluminium panels  Green metallic composite aluminium cladding  Fully glazed management suite and common rooms to give street presence and internal activity at ground and first floor levels o e a OCONNELL EAST ARCHITECTS

  13. Block A – Articulation and Materials  Blue engineering brick at ground and first floor  Silver metallic and dark grey metal cladding to tower with horizontal joints.  Replicated lounge bay window projections of dark grey metallic metal cladding incorporating coloured aluminium panels used on Blocks B & C  Cantilevered elements to SE prominent corner  Glazed lift shafts and stair core landings o e a OCONNELL EAST ARCHITECTS

  15. Fleming Proposals  Early Completion 2009 – 1 year early  Reduced floor to floor height from 3075mm to 2800mm  Fundamental change in overall super structure and foundation design  Provision of an additional 23 study rooms – primarily to provide structural continuity but gave benefit to Client of additional revenue  Blocks B & C Relocation/configuration of ground and first floor common room/multi-use spaces and refuse stores  Incorporation of 1m deep transfer structures at 1st and 2nd floor levels  Investigate alternative cladding materials for Block A  Block A – reconfigured floor plate due to the south-eastern cantilever structures and reduced core structure o e a OCONNELL EAST ARCHITECTS

  25. Off-Site Construction - Advantages  Off-site construction allows the build process to run concurrently can equate to as much as 60% reduction in programme  Off-site construction offers improved building quality due to the controlled construction environment i.e. factory finish and turn-key solution  Cost certainty for Client  Reduced waste (off cuts, packaging etc) – new legislation in the UK forces construction clients, designers and contractors to adopt a more sustainable approach to waste.  Off-site construction facilities are enclosed and secure protecting against weather damage and delays as well as theft.  Permanent, long term employment for skilled labour both within the factory and engineers on site.  Improved Fire/Acoustic performance (effectively two walls between all rooms with a cavity)  Improved Thermal Efficiency  Safety - Reduced number of workers/man hours on site - Workers have a reduced number of tasks / hazards - System building allows detailed analysis of risks at each stage  Less noise, dust and general disturbance  Fewer commercial vehicle movements o e a OCONNELL EAST ARCHITECTS

  26. Off-Site Construction - Disadvantages  Economically efficient for repetitive floor plates only  Most off-site modular systems are limited to low-rise due to structural stability of modules  Modules are limited in size by transport legislation and width of delivery vehicles Preferred sizes (but larger sizes /heights are common) - Width 4.0m outer face of floor steel - Length 10.6m outer face of floor steel - Height 2.8m floor to floor  Design freeze required early in the project. VMS System is 18 weeks prior to scheduled delivery on site.  Size of crane required to lift modules may not be cost effective with smaller quantities  Transportation can be costly if site is remote, significant distance from factory and if loads are wide  No flexibility or option for future adaptation o e a OCONNELL EAST ARCHITECTS

  27. Off-Site Construction: Limitations Block A  To comply with the approved scheme cantilever elements were retained to the SE elevation.  The internal room configuration was adjusted to provide some structural continuity together through the modules.  Barratt Mahony designed an additional structural H-frame to provide support to the underside of cantilevers.  Introduction of non-standard floor plates within modular construction can be costly. o e a OCONNELL EAST ARCHITECTS

  28. Points to consider:  Are traditional and modular construction methods really that different?  Did working with an off-site supply chain help or constrain design and flair on the project?  What are the critical success factors for architecture and designer working with offsite?  Would we recommend off-site?  Limitations of off-site construction? o e a OCONNELL EAST ARCHITECTS
