SCOLA STEEL FRAME
The Structural Steel Frame described in this leaflet was developed by SCOLA ( the Second Consortium of Local Authorities) The Consortia was a voluntary associations of authorities formed to share resources and their experience in the design and construction of building projects.
The frame is available for use on an individual project basis to other public authorities and to the private construction sector.
There is a central development group, now operating under the name of PILLAR CONSULTANCY which consists of a team of experienced professional advisors who provide technical and cost guidance to users, and control purchasing arrangements. Constant research and monitoring have enabled us to develop construction techniques which can provide users with the buildings they want, on time and within budget.
Over the past 30 years over 2000 buildings using this construction have successfully been completed in the UK and overseas. Use of the steel frame will bring to you the design and structural expertise accumulated during this time.
The Structural Steel Frame offers:
Single or multi-storey construction
Pitched or flat roofs
Roof gables, hips, valleys, mansards and dormers
Options for roof and floor loadings
Value for money
Optional floor decks, staircases and other components
Rapid design
Rapid construction
A library of assembly details
Savings in professional time
Savings in Structural Engineer's fees
Pre-designed components
Pre-determined prices
Pre-ordering facilities
Early 'Budget' prices
DESIGN POSSIBILITIES
The Structural Steel Frame offers considerable design possibilities based on a 600 mm structural grid.
Some of the variety of forms which are possible are illustrated below, and all are available in one, two, three or four storey construction. Buildings from 5 to 8 storeys are also possible, subject to some limitations on their basic shape for reasons of structural stability.
Plan forms can range from simple rectangular shapes to the more complicated conformations of 45° modelling with a variety of roof shapes, enclosing large or small spaces.
Roofs can be pitched or flat. The angle of pitched roofs is 18½° (1:3); other slopes are available, with 9½°, 26½°, and 34° being preferred. Pitched roofs may be dual or mono, with gables, hips and valleys; covered in light weight sheeting or tiled. Flat roofs may be covered in asphalt, felt or HT felt.
Cantilevered roofs, floors and balconies are possible, which not only give the opportunity to achieve variations in elevational treatment, but can assist environmental functions, such as the reduction of glare and solar gain.
Variations in roof and floor loadings are accommodated generally or in specific areas by modifying the spacing of beams: this can usually be done without affecting column positions.
The structure employs both rigid beam to column connections and 'pin' jointed connections with diagonal bracing as required. A modified version is available for sites subject to coal mining subsidence, or with poor bearing characteristics.
Secondary component ranges and/or a library of assembly details are available for:
These components are available as a result of competitive tenders invited by the Consortium, which also issues cost planning information to users.

THE SERVICE
A structural design consultancy is provided by the Consortium for all projects using the frame. Wind loadings and foundation designs are tabulated for a wide range of conditions, as are conditions for the stability of external walls.
The professional staff of Pillar Consultancy provide additional specialist knowledge, and are available to carry out feasibility studies and provide comparative costs on alternative solutions. Special conditions can be accommodated and solutions can normally be achieved within the design and costing criteria established for an individual project.
The need for a project structural consultant is minimised and for most designs eliminated entirely, this can achieve considerable savings in fees. Standard design information is made available through the Consortium Structural Engineer project loadings are supplied by the Consortium steel frame manufacturer, who has complete responsibility for design, manufacture and erection.
A major advantage of the frame is that, when time is a critical factor, it may be manufactured before the contractor is appointed. Projects of £2 million value have been completed within 11 months of receipt of order.
