The Architectural System

To cut a round tube and rejoin it mitred at right angles – this was the idea of the architect Robert Mallet-Stevens (1886 – 1945), whose lever handle is today known as the “Frankfurter Model”.

HEWI has derived a universal system on the basis of the simple yet clever design. Linear, functional, without superfluous details: System 162 convinces in the sanitary room through its clear design. Matching hardware, signs and handrails are available.

The minimalist design concept of System 162 not only has a convincing reduced design and a high degree of functionality, but also persuasive quality to match.

The System 162 sanitary products are available with a high-quality chrome finish. The accessories can be combined with inserts made of satin-finish glass or high-quality polyamide in pure white or anthracite grey.

System 162 is augmented with a rail with shower head holder and shower basket. The support rail provides additional comfort and convenience.

1513 Delta - AlertMaxx rgbSpeedy installation and reliability in operation, these are a couple of the many features found in the new AlertMAXX alarms from Delta Membrane Systems. They are used in sump installations, with the new DMS270 AlertMAXX being used for ground water and surface water applications, and the DMS269 AlertMAXX for foul water use.

Just two fixings are required along with the connection of mains power and a float switch for the AlertMAXX to be fully operational. Should a power cut occur, a battery backup has been incorporated into the design to ensure constant operation.

Each model has an LED display that shows the current status, high level alarm, previous cancelled alarms, mains failure and service reminder. ‘Volt free’ contacts are included as standard for connectivity to building management systems.

As an option, a cable can be supplied to download the internal log from AlertMAXX to either a PC or iPad showing all events that have occurred in the past.

The foul water option is supplied with a robust and reliable pendant type float switch which is fixed to the pipe-work or pump, or is left free hanging using a float weight to allow correct operation.

With the ground water AlertMAXX, a ‘broken finger’ float switch is fitted to give accurate operation and allow the alarm signal to be given after pump one fails, leaving pump two (where fitted) to operate normally.

The design of the new alarms also prevents accidental deactivation, although the alarm can be muted.

A low cost telemetry – known as MessageMAXX – can also be added.

Cembrit has developed a fibre cement slate guide to provide specifiers, craftsmen and trades people with the relevant information for the successful design and installation of pitched roofs with ever popular fibre cement slates.

Fibre Cement Slate GuideThe book demonstrates how Cembrit’s knowledge of all forms of double lap slating, combined with their knowledge of fibre cement technology, offers users peace of mind not available from other suppliers. The guide highlights the wide range of slates and accessories the company offers. The 80-page document, entitled ‘A Guide to Double Lap Slating with Fibre Cement Slates’ provides information on colour and format availability, as well as a full explanation on design considerations, technical specification and installation.

“Cembrit has been manufacturing fibre cement products for over 80 years” explains Ged Ferris, Marketing Manager of Cembrit. “The content of the brochure draws on that depth of experience to offer detailed advice to anyone wanting to specify and install fibre cement slates. Fibre cement man-made slates continue to grow in popularity, due not only to the cost and installation benefits over natural slates, but also their aesthetic advantage over concrete tiles. Our aim is to support this increase in popularity by providing a useful document that covers the key aspects of fibre cement specification.”

The Cembrit range of fibre cement slates includes Westerland, Moorland, Zeeland, Jutland and Diamond, all offering their own unique appearance. The slates are complemented by matching fibre cement ridges, ventilation solutions and fixings. Manufactured to the highest European standards using Portland cement together with a formulation of superior blended synthetic and cellulose fibres, Cembrit fibre cement slates are finished with a high quality, semi-matt acrylic coloured coating to the face and edges and a tinted, high performance binder to the back face. Cembrit fibre cement slates are the most accredited on the UK market.

Addagrip, the UK’s leading manufacturer of resin exterior surfaces, has been involved in the ‘Broad Walk’ project at the Royal Botanic Gardens, Kew, to create the longest double herbaceous borders in the UK.

The 300m long borders either side of the Broad Walk, from the Orangery to the Palm House Pond, will be planted with swathes of vibrant summer flowering perennials, grasses and bulbs to form a spectacular new horticultural feature.

Addagrip, together with approved contractor True Grip Ltd, installed over 3000sqm of innovative new porous paving system, Terrabase Rustic, on the instruction of main contractor Kier Facilities Services. The product provided the rustic-looking finish that Kew required and could be installed over the existing surface with minimum environmental impact and disruption.

As drainage was another key requirement for the project, Kew also selected Terrabase Rustic for its larger stone size of 6-10mm to provide maximum porosity.

The new Terrabase Rustic surface is hard-wearing and low maintenance, providing a seamless, natural rustic pathway with no loose stone, which looks very much at home in the grounds of London’s historic Royal Botanic Gardens.

The Broad Walk path has recently re-opened, allowing the public to begin enjoying the experience. New plants will begin to arrive in autumn 2015 and planting will continue until early summer 2016 to complete the project.

Howe Green Provides Easy Access to Essential Services at Southmead Hospital

Southmead_34B6553Over 100 of Howe Green’s Visedge access covers were installed at Bristol’s £430million state-of-the-art Southmead Hospital. With the floors of the new super-hospital facing foot traffic from millions of visitors and staff each year, a heavy duty, hygienic and tamper-resistant solution was required to provide access to under-floor drainage and services. The Visedge range provided a cost-effective and low maintenance solution and AC Flooring carried out the installation for main contractor Carillion.

Howe Green’s Visedge covers are double-sealed to meet the highest standards of hygiene and security. The range was developed specifically for use with flexible sheet flooring systems. Unlike similar products, Visedge allows sheet flooring, including PVC or linoleum, to be locked into the cover and frame by hot welding to a pvc section sealed to the surface. This creates a permanent joint and eliminates water ingress and peeling.

Howe Green manufactures a comprehensive range of access cover solutions for floors, walls and ceilings. Their 7500 Series stainless steel access covers were also supplied for the Southmead project. These were installed in ground floor areas of the hospital, where a heavier loading for service vehicles and bulky medical equipment was needed.

Crittall solution for listed Lidl development

Successful supermarket chain, Lidl, faced an unusual challenge with its plans to develop a store on the Lower Bristol Road, one of the main routes into the city of Bath. Occupying the chosen site was an empty and vandalised single storey industrial building circa 1966.

IMG_1935 (2)Lidl invariably plumps for new-build stores but, having split the acquisition of the site with a property developer, the new owners’ demolition plans were thwarted by an unexpected Grade II listing.

The reason for English Heritage’s attention was the mode of construction of the otherwise unremarkable structure. The 57,000 sq ft. building was the first example in the UK of the use of the Mero Space Frame. This German system, incorporating solid steel tubes of standard length connected by spherical metal nodes, was designed to support the roof with the minimum number of columns thus creating a relatively clutter-free space for manufacture, in this case high-end furniture for customers such as Harrods and the Cunard shipping line by well-established local firm Bath Cabinet Makers.

Birmingham-based Lapworth Partnership, which has designed a number of Lidl’s new stores, was engaged to meet the challenge and worked with Bath and North East Somerset Council’s conservation officer and English Heritage in the South West region to arrive at an acceptable refurbishment and upgrade of the building.

‘The technology at the time the original building was constructed was restricted. So it was modular panels with single glazing with louvres,” says architect Michael Lapworth. “It was a very basic industrial structure with no insulation in the walls and continuous glazing to show off the space frame.”

Having achieved listed building consent the firm set out, in Lapworth’s words, to create “a modern version of the existing.” In order to replicate the slenderness of the original aluminium fenestration a steel window system was selected for all the continuous high-level glazing.

“The only choice for this was the W20 frame system from Crittall,” says Lapworth. The company supplied banks of coupled W20 and MW40 section fixed frames, double glazed in long runs. These were interspersed with bespoke insulated pressings both internally and externally to allow a link between upper and lower level windows, roof and internal services.

Another element was a narrow metal fascia running at roof level around the building. This was recreated in steel together with its specially designed fixing system to replace the original aluminium and asbestos sill.

A further aspect of the original design is a series of large louvred panels that originally had been attached to internal plant but which were an important visual element of the external elevation. Crittall reproduced these metal louvres.

The result is a ‘new’ building that still exemplifies the use of the Mero Space Frame that stirred widespread comment in the construction and architectural press 50 years ago.

Lidl Property Director James Mitchell, said:

“Lidl are delighted to have completed the refurbishment of the Grade II listed former Herman Miller building on Lower Bristol Road, Bath. This project has had many challenges at every stage not least the physical refurbishment of the building. We are extremely pleased with the outcome and the feedback from our new customers has been excellent. The Crittall supplied window system has perfectly recaptured the spirit and rhythm of the original building whilst at the same time bringing it in to the 21st century. We now look forward to serving our new customers in Bath and hope to work with Crittall Windows again in another project soon.”

Opened in April 2015 the store, one of Lidl’s largest, occupies some 60% of the interior.

Retrofitting an outside light isn’t the trickiest tasks most contractors will face. However, it can be fiddly and at times a little time consuming. To see how straight-forward it can be, we followed the installation of a 5W LED Energy Saver PIR Bulkhead Light from Timeguard. Positioning the unit was simple, the instructions on the box indicated 1.8m high, and the homeowner indicated whereabouts he wanted the unit.
