Kawneer curtain walling holds a unique key to a gateway building
Kawneer curtain walling holds a unique key to a gateway building
Fritted glazing is the star at Manchester's Citylabs 2.0.
Two types of curtain walling by leading UK manufacturer Kawneer met a quartet of criteria for a new building at the gateway to Europe's largest clinical-academic campus.
Kawneer's AA®110 SSG (Structurally Silicone Glazed) and AA®100 capped aluminium curtain walling almost completely wraps the new £25 million Citylabs 2.0 development within the Oxford Road Corridor innovation district in Manchester.
Citylabs 2.0 is part of a £95 million expansion to the Citylabs campus which is located at Manchester University NHS Foundation Trust's (MFT) Oxford Road hub and is a partnership between MFT and the UK's leading property provider to the science and tech sector, Bruntwood SciTech.
The project builds on the success of Citylabs 1.0 which opened in 2014 and is fully-let, and Citylabs 2.0 will provide world-class lab and office space for global diagnostics company QIAGEN who have 100% pre-let the building for their Global Centre of Excellence for Precision Medicine.
Kawneer's AA®110 SSG curtain walling with flush silicone sightlines has been used throughout, while the AA®100 version with 50mm sightlines features on the ground floor entrance of the 8,500m2 state-of-the-art building designed by frequent Kawneer specifiers, architects Sheppard Robson.
The practice conceived Citylabs 2.0 as a block of accommodation with one elevational treatment, with recessed areas carved out of the main block clad in alternative materials. To realise this concept, the main body was formed in the Kawneer AA®110 flush cap-less curtain walling, with a digitally printed design to the glazing.
The concrete frame of the building provides clear open floor plates to support different work typologies while the post-pensioned floor slabs provide clear, uninterrupted soffits for ease of services distribution.
The recesses at level 5 and the plant room are clad in ribbed fibre cement panels, the recess on the Hathersage Road elevation is clad in louvres, and the recess to the main entrance is the Kawneer full-height AA®100 curtain walling with accentuated vertical caps. The set back edges, and entrance canopy soffit, are clad in a bright coloured red anodized metal panel.
Sheppard Robson associate Mary-Ann Crompton said: "The sub-contractor chose Kawneer as the best product to realise the design intent and it achieved the required performance specification in terms of aesthetics, thermal, acoustic and movement requirements."
The AA®110 SSG curtain walling, with its wider 65mm back box, is typically specified to minimise building movement and at Citylabs 2.0 was complemented by the fritted glazing and spandrel panels.
"The existing adjacent buildings are Grade 2 listed and the cutbacks to Citylabs 2.0 have been organised to respond to the location and scale of them. The etched design to the glazing refers to details within the retained chapel which is to be refurbished as part of further future developments for Citylabs 3.0," said Mary-Ann.
She added: "The glazed elements of the curtain walling form the major component of the elevational design and has helped to fulfil the aesthetic aspirations for the project. In addition, aluminium is totally recyclable and is therefore a good material to use. This characteristic helps towards achieving a sustainable design."
The Kawneer systems were installed for main contractor Sir Robert McAlpine over six months by teams of up to eight people from Kawneer-approved specialist sub-contractor and dealer Bennett Architectural Aluminium Solutions.
Director Rob Bennett said: "The project was fully enclosed in Kawneer curtain wall. It was a large project for us and had to be installed within 25 weeks. The AA®110 curtain walling allowed increased building movement capability.
"The glass on it was quite unique. We worked with the architect and designed a frit pattern that was used as part of solar control. It has a very unique whirl and is quite striking."
Mary-Ann said: "We have used Kawneer on many of our projects over the years and have found that the technical and sales departments are very helpful with providing information at the early stages of design."
Businesses which locate to Citylabs have direct access to MFT's specialist clinical resources and expertise from researchers, clinicians and procurement teams as well as Bruntwood SciTech's specialist growth support and events programme, including access to funding, talent, new markets and academic connections.
Kawneer glazing systems help hospital open early for Covid
The Grange University Hospital features modular windows by Kawneer.
Architectural glazing systems by leading UK manufacturer Kawneer that were installed off-site helped elements of a £350 million new hospital to finish almost a year ahead of schedule and help with the Covid crisis.
Kawneer’s AA®720 HI Reflex Plus windows were fabricated into precast sandwich panels at the main contractor’s off-site factory for installation at The Grange University Hospital at Llanfrechfa Grange in Gwent, South Wales.
The Kawneer windows were complemented by the manufacturer’s AA®100 zone-drained curtain walling with 50mm sightlines, and three types of entrance doors – AA®720s, AA®190 TBs and folding/sliding AA®3720s.
The windows featured both glazed and spandrel panels which were thermally enhanced to comply with the thermal model, using a mineral wool core to comply with Building Regulations as well as providing bright colours for the façade in the form of orange face caps.
They also included feature pods designed by specialist sub-contractor and approved Kawneer installer/dealer Bennett Architectural Aluminium Solutions which were extruded by Kawneer at its factory in Runcorn, Cheshire.
Designed by architects BDP to BIM Level 4, the 560-bed Grange has already won two awards – Constructing Excellence Wales for Digital Construction and an Off-site Award. It comprises 11 operating theatres, one Cat 3 Laboratory, two MRI suites, two CT suites and an education block.
Previously known as the Specialist and Critical Care Centre, it is the centre piece of a new model of healthcare delivery, serving more than 600,000 people, and will deal with all major emergencies, including the Covid pandemic, as well as 40 specialist services, with a helicopter pad for patients who need to arrive by air ambulance.
Careful modelling of staff and patient flows in the design phase allows early streaming to a point of care and access to timely and expert care. This is supported by dedicated circulation systems for front-of-house and back-of-house services, enhancing patient privacy.
Designed to be flexible, adaptable and expendable, the 55,000m2 hospital’s universal rooms allow operational flexibility and blurring of departmental boundaries to deal with changing demand.
Beds were released 30% earlier than the original programme through productivity efficiencies during the Covid crisis while the DfMA (MMC) approach saved 237,000 working hours - equivalent to a 23% overall planned programme saving.
In addition, 821 precast columns and 1,200 precast wall modules were installed, representing 85% and 95% working hours savings respectively.
Victoria Head, project director of project and cost managers Gleeds, said: “With the best will in the world, fundamentally, had this been a traditional build with the same start date  we would not have been in a position to offer support to this national pandemic and the NHS.
“We’ve always been proud of the MMC involved at the Grange and the programme savings which it offered compared to a traditional build, but never have the benefits been more apparent than during this crisis.”
BDP lead designer Adrian Hitchcock said: “We have used Kawneer systems on multiple projects. Familiarity with their products from previous successful use is a positive. Demonstrating compliance is important and Kawneer do this.”
Work on the build involved careful segregation fully endorsed by infection and building control and fire officers.
Rob Bennett, pre-construction director for Bennett Architectural Aluminium Solutions, said: “The hospital was a compelling case for the use of DfMA in large-scale healthcare construction projects, even opening far ahead of schedule to treat patients during the pandemic.
“Kawneer products were specified due to the company’s experience with Bennett’s in delivering extensive offsite construction projects in the healthcare sector.”
Judith Paget, chief executive of the Aneurin Bevan University Health Board, said: “It will help us to create a much improved care environment, timely access to emergency care, and ensure patients get the best outcomes from their care.”
