LIFT SERVICES

The Lifts Services comprise two high speed geared type Lifts. The Passenger and Directors Lift, serving from the Main Entrance Showroom to all Floors, has a speed of 300 f.p.m. with dual control, its full load capacity being 15 passengers. During the busy period of the day the Lift would be under attendant control, but during other periods the control will be switched over to full automatic. Under the first operation indication is given in the car of any calls made, while with the second operation the Lift will automatically respond to floor calls. The car and landing doors are electrically operated, opening when the car arrives at any landing, and closing again on the pressure of any car or landing button. When the doors are closed, the starting sequence comes into operation. Accurate floor levelling is assured by the use of auxiliary equipment on the micro-principle. Floor levelling is maintained under all conditions of car load.

For the Works Section of the Building, a heavy duty Goods Lift is installed, operating at 225 f.p.m., with a normal load of two tons. The operation and control of this Goods Lift is similar to that for the Passenger Lift.

A pneumatic car hoist, is fitted in the Garage to facilitate cleaning and maintenance of vans and lorries used by the Company. High pressure car washing equipment is also provided, complete with pressure greasing equipment.

SANITARY SERVICES

The Sanitary Services throughout the Building are installed in copper on the One Pipe System. All external services are grouped on the walls of the main area ,at the. rear of the Building, thus permitting the whole of the main elevation to be free of pipes.

The materials used for the external services are heavy cast iron coated pipes for main stacks with lead branches. All internal services and branches to' all fittings are in solid drawn copper tube with bronze welded joints. The rainwater pipes from the main roof are carried through the Building adjacent to the main elevation. These are all in solid drawn copper tube and terminate at high level in the Basement, where they connect into cast iron pipes connected' to the main sewer.

All other services for soil, waste, etc., are discharged through main cast iron drains to a second sewer connection.

The layout of the Sanitary Services has been designed to permit adequate accommodation for the whole of the Staff and visitors. Special arrangements have been made for the accommodation of male and female members of the Staff, also the Works Section. The hot water services, to the whole of the sanitary units are supplied from steam heated calorifiers in the Boiler House, the temperature being regulated by thermostatic control.

Cold water services are supplied directly to all the sanitary units from the storage tanks on the roof of the Building.

For the Works Section large double washing troughs have been installed, permitting easy access by the Works Staff. The flow of water to the troughs is regulated by pedal action valves independently controlled, the water being delivered through sprays.

Throughout the Building special drinking fountains have been installed, of the latest hygienic design.

In connection with the Plating Department and other Sections using acids, separate waste connections have been installed, terminating in an acid neutralising tank constructed on a similar principle to the petrol interceptor. After passing through the acid neutralising tank, the effluent passes to the main drains. In connection with the Garage, the whole of the floor drainage discharges through a triple chamber petrol interceptor an thence to the main drains.

The whole of the Sanitary Services throughout the Building have been installed in such a manner to permit easy' access for cleaning and general maintenance without undue inconvenience to the occupants.

SPRINKLER SERVICES

The whole of the Works Section of the Building, including the Basement, Boiler House, Air Conditioning Room, etc., are protected against fire by a complete sprinkler system. In addition, for general fire protection purposes, dry risers are installed throughout each stair well, with a' hydrant point on each Floor. These dry risers terminate on the roof with fire hydrant connections. As a further protection, chemical and foam extincteurs, also sand and water buckets are installed throughout the Building, in accordance with the requirements of the Authorities.

PORTLAND STONE

The whole of the Portland stone used for the Marylebone Road elevation of the National Cash Register Company's new building was quarried in Portland, fabricated in London and erected on the site by the South Western Stone Co. Ltd.

To ensure the best results, it is essential that the whole, or specified portions, of the stone intended for a building should come from definite districts, since the stone from different quarries varies slightly in regard to colour and texture. With this end in view, the South Western Stone Co. have cleared large areas in their Cottonfields, Perryfields and Coombefields Quarries, thus enabling the Architect to visit the quarries and select stone of the desired quality, with the assurance that the output from that quarry will be sufficient to meet his requirements.

Portland Stone, despite the number of synthetic and other materials now on the market, continues to be regarded as the foremost of the building materials for city work of magnitude and importance. Both its aesthetic value and weathering qualities cannot be surpassed. Not only does it satisfactorily withstand the attacks of smoke-laden atmosphere, but its appearance actually improves. The exposed surfaces of the stone are washed clean by rain whilst the shielded and recessed portions take on additional colour from smoke deposits, thus producing that desired variation which enhances the attractiveness of the facade.

Although Portland stone has been quarried extensively since the days of Sir Christopher Wren, there is no reason to suppose that the supply of good building material is likely to be curtailed. Large areas of land in the best quarrying districts have scarcely been touched, and inspection will prove that there is an abundance of stone of even quality and free from unsightly shells, which is at least equal to any stone that has been quarried in Portland.

Some years ago the South Western Stone Co. acquired 60 acres of some of the most important, quarrying land, both freehold and. leasehold, in the Isle of Portland. Since that time they have given special attention to the analysis of the geological strata comprising the various beds in the quarries, have made extensive clearances over large areas containing stone, and have introduced the most up-to-date equipment. In addition to this, their large works at Battersea, where the most modern plant has been installed, are capable of handling masonry contracts of every type and size, and they contend that their machine-worked stone is, from every point of view, equal to hand-worked masonry. Among the very large contracts the South Western Stone Co. have had the privilege of handling during recent years are the London County Hall Extension, the Fire Brigade Headquarters on the Albert Embankment, the Masonic Peace Memorial, Shell Mex House, Luton Town Hall, the Royal Empire Society's Building and the Science Museum, South Kensington.

ARCHITECTURAL METALWORK

The metalwork as shewn in the various decorative units such as the balcony railings, and laylights, is an example of the rich effect which can be obtained by the combination of metalwork and etched glass, further emphasised by illumination.

The metalwork itself in this case is executed in cast bronze, chased and toned. The colour of the glass has been selected to be in harmony with the colour of the metalwork, and the ornamentation of the glass designed so as to make the glass panels effective when illuminated from beneath.
