Internal spaces are linked together both horizontally vertically through atriums. Vertical Circulation is pri via feature stairs within the main full height atrium.

BUILDING DETAILS To secure planning consent, the architect designed a building which tiered from front to back to minimise the impact on the surrounding residential properties and to maximise the impact to the Penrhyn Road elevation. ​ The building is recti-linear with a staggered rear elevation to accommodate the shape of the site. Arranged over 6 floors the new building creates over 11,000m2 of flexible interactive teaching and learning spaces. The tiering of the roofs creates usable external spaces which link to the inside. The building is wrapped on three sides by a full height structural concrete colonnade which creates external spaces, opportunities for vertical circulation, areas for plants and trees, and linkage to the pavement and subsequently the community. The colonnade serves to remove barriers between the university campus and its surrounding area and seeks to ‘open the universities doors’ to the world outside.

y and imarily

RESPONDING TO THE SITE The Townhouse Building replaces a 1960’s prefab structure which housed a number of functions including the Student Union and the Universities archives and library. The new structure is situated on the site of the existing building and is directly adjacent to Penrhyn Road which is the main arterial route into Kingston from the south which means it is extremely busy in terms of traffic along with being part of the London red route and cycleway. The site is triangular in plan with the remaining sides directly abutting the existing university buildings and a residential street.

7

PCELTD.CO.UK

The 71, 281, K2 and K3 buses all run along Penrhyn Road and there are stops directly outside the main entrance.

The University has limited on-site parking facilities and prioritises staff during core working hours (Monday to Friday, 7.30am to 4.30pm).

LINKS TO COMMUNITY The internal structure of the building provides a three-dimensional matrix, one singular complex space, which links the various required uses to one another, while at the same time giving each its own identity and privacy. Externally the highly imaginative façade is made up of an open undercroft colonnade at ground floor to invite public use and activity, above which three cascading terraces form hanging gardens giving a sense of landscape connecting from ground level to the top of the building.

The stage 3 design essentially discounted traditional frame and slab construction and selected a ribbed slab arrangement. This was primarily driven by span:load requirements and the drive for as much exposed concrete surface as possible to assist with the heating and ventilation strategy. The frame was designed as an insitu Reinforced Concrete and the architect and engineer were debating either an insitu ribbed slab or precast hybrid.​ ​he Colonnade was primarily architectural precast concrete T columns and beams with an omnia type slab with an insitu concrete topping forming the walkways. The horizontal drainage system was to be embedded within the insitu topping with water falling back to the envelope line and then down RWP’s behind the precast mullions. ​

ARCHITECTURAL INFLUENCE ON STRUCTURE: FABRIC FORMWORK Sheets of flexible, permeable fabric are held and tensioned in a system of Formwork to form the final cast shape. The design is iterative to achieve the optimum solution of both geometry and formwork design. Solution would be best suited to precast T-Beam elements and insitu frame.

18

PROS • High quality surface finish and increased durability (permeable fabric membrane allows water to bleed from the mould).

• Timber formwork system shown if figure 2 can be re-used.

Decreasing the depth of beams for shorter spans is achieved by adjusting the fabric sag.

• Curved tapered sections are possible so could taper from main span depth to a shallower depth at the end of the shorter spans • Lightweight formwork and less formwork = reduced material, transport and storage cost.

CONS • Some potential finish differences may result between the use of timber formwork at the soffit and fabric of the beam.

• Minimal precedence for its use on a large project, its use and viability will need to be discussed with the Contractors.

LONG SPAN RIBBED SLAB DEVELOPMENT

Various rib profiles were investigated. Ribs varied in section, reinforced or prestressed/post-tensioned and construction methodology, ie insitu concrete or composite precast concrete (hybrid).

A ‘long span’ ribbed slab was determined to be the optimal solution for the following reasons: • • • • •

22

Structural efficiency and capacity Material efficiency Internal vertical space flexibility Services integration Aesthetics

The question now was what is the optimum rib arrangement, how to achieve the ribbed soffit, detailed integration with the primary frame?

At this stage the primary frame was to be Insitu Reinforced Concrete and the ribbed slab was still to be determined.

Steel Moulds for Precast Ribs

Main issues: • Expensive mould and infrastructure set-up • Heavy ribs would need to be lifted into position • Hybrid strategy complicates the procurement process and the appointment of a specialist with the skills to construct in this way

GRP Moulds for Insitu Ribs

Main issues: • Significant temporary works • Significant on site set-up time • Major health and safety risks • Risk of damage to formwork during casting

Polystyrene Moulds for Insitu Ribs

Main issues: • Significant temporary works • Significant on site set-up time • Major health and safety risks • Risk of formwork damage during casting • Polystyrene would require extensive replacement strategy due to degradation

CONCEPT TO REALITY Typical beam to slab interface and typical 610mm deep DT slab profile at 3.2m wide to suit a structural grid of 6.4m.

PCE solution based on standard Double Tee slabs whose widths are configured to the Kingston structural bay sizes. Precast concrete columns and beams form the primary structural frame.

610-810-1010 ribs, subject to spans and loadings

At Stage C the design team were unsure whether the pipework would be cast within an insitu concrete slab or within the structural topping of a composite slab system.

INTEGRATION OF SERVICES WITHIN THE STRUCTURE TABS System Exclusion Zone for TABS System In-Situ Concrete

The ribbed soffit provided the opportunity to take advantage of the TABS (Thermal Activated Building) system which utilises the thermal mass of the concrete structure to cool/ condition the air within the building. Ambient water is fed through the embedded pipework to control the concrete surface temperature. This means that warm air rising within the building is then cooled to maintain a comfortable internal air temperature without the need for significant HVAC (Heating Ventilation Air Conditioning) installations.

TABS SYSTEM Overview

The Kingston University Estates Team required a heating and cooling solution for its new town house development, which could fulfil the following requirements: reduce energy loads, maintenance and carbon emissions. What’s more it was imperative that a longterm financial benefit could be achieved.

The town house development, which will form a key component of the University’s Penrhyn Road campus, will be completed in time for the 2019/20 academic year. The campus will also feature a flexible teaching space, cafeteria and landscaping.

26

Uponor’s Involvement

Early engagement with the main contractor (Willmott Dixon) was imperative for ensuring project success. For example, Willmott Dixon initially highlighted that a minimalist design would be adopted with clean lines and open spaces. As such, there was no room for cumbersome units or voids.

The beauty of Thermally Active Building Systems (TABS) is that it can be embedded (pipes) within the concrete mass of a ceiling in a discrete way, so as not to impact the overall aesthetic appeal. It provides an ambient temperature within the building by heating and cooling the water supplied with minimal energy and is linked to the outdoor climate.

The TABS was installed a year ahead of the completion date and fulfilled the budget and time constraints set out.

Benefits

TABS will assist Kingston University with achieving its aim of a BREEAM ‘Excellent’ accreditation by reducing overall energy consumption. What’s more, it is highly versatile and can be adapted according to conventional and renewable energy sources, whilst also taking into consideration site dynamics.

TABS only require a minimum adjustment in the water temperature of +/-4 or 5oC and works silently in the background (perfect for academic and work environments) as a “fit and forget” solution.

STRUCTURAL PRINCIPLES Idealised structural principles diagram identifying load distribution through the frame structure, back to the stiff cores and down to the foundations.

Columns in the northeast corner of buildings act as fixed base cantilevers above level three to resist lateral loads in absence of a core.

Key issues: • Temporary stability • Stability Cores didn’t necessarily run full height and were disparate in terms of position • Stability for the Colonnade had to be provided by the main superstructure but the two structures needed to be independent due to thermal expansion and contraction

ATRIUM AND FEATURE STAIRS Vertical circulation through the structure is primarily via a full height atrium at the front elevation of the building which has three large feature stairs spanning the length of the atrium between floor levels. A composite solution was developed for the feature stairs as spans were up to 15.0m long by 4.4m high. The solution combined a fabricated structural steel frame with integrated stair trays. The soffit of the frame was clad in precast concrete panels to give the appearance of concrete and the stair trays were cast on site to keep the weight of the frame to a minimum.

COLONNADE CONSTRUCTION Construction of the colonnade was a significant challenge due to the complexity of the embedded services strategy, difficulties in accessibility and the temporary stability requirements. The colonnade is manufactured from a high-quality architectural finish concrete with all surfaces exposed except for those concealed by adjoining elements and structure. The temporary restraint of elements had to be discreet in terms of how struts and props connected to the elements and in most instances, stabilisation had to come from the previously constructed colonnade structure. Careful sequencing combined with a design solution heavily influenced by the assembly methodology and PCE’s ‘inhouse’ construction expertise made the delivery of the colonnade possible.

OUR PEOPLE From the Project launch seminar, at which the University of Kingston and Grafton Architects set out and explained their visions for Townhouse, it was clearly apparent that the only way the Project could be a success was through a collaborative approach to every facet. One team, one Project, one shared goal - “To create a heart for the University of Kingston”.

Through Design, PCE’s internal team of Engineers and Structural Technicians were driven to maintain the architectural aspects of the building rather than opting for simpler alternative structural approaches. The integration of drainage and cast-in mechanical and electrical requirements were incorporated without compromise of the vision.

The Manufacture was well controlled through PCE’s supply chain partners with quality at the forefront of every decision that was taken in how to produce the various elements.

Assembly was completed by an average number of 15 of PCE’s multi-skilled operatives who worked through all weathers whilst maintaining safety and quality in every task undertaken to achieve close to 50,000-man hours with no reportable incidents. The logistically challenging site and location was well-ordered throughout with an excellent understanding and mutual respect between the construction teams of all members of the Project team.

Professor Steven Spier, Vice Chancellor of Kingston University commented: “World-class architecture isn’t just the preserve of the Russell Group! I’m delighted that with Town House, everyone who visits, studies in, and works at Kingston University now has access to a beautiful and inviting space in which to learn, socialise and just be.”

Roger Forsdyke, Managing Director of Willmott Dixon in London & South has stated that: 64

“Town House was a hugely ambitious project – one we fully embraced.

Although it was complex and highly challenging at times, it’s testament to the team’s dedication that the original design has been realised to such exacting standards.”

DELIVERY

a sustainable solution was fundamentally at the heart of the Universities vision. The Townhouse is an e building can be used throughout the life cycle of the building to minimise carbon emissions. In addition, s was significantly reduced through the use of a DfMA strategy combined with extensive use of cement ing project completion show that for offsite manufactured precast concrete units, which accounted for he CO² footprint was less than 230kg/m² for the total building floor area.
