GENERAL GUIDELINES FOR FACTORY BUILDINGS
The general guidelines given below are to be followed by
all BOI Enterprises in the planning, designing and construction of factory
buildings. The Architect/Engineer designing the factory complex shall
also take into consideration inter-alia, the location, site conditions,
services, required, number of workers, processes involved, raw materials
used, factory effluents and solid waste to be disposed of etc., before
finalising the building plans for submission to the BOI for approval.
Selection of Site
In selecting a site for the factory buildings of the proposed
project, among other things, the following aspects should be taken into
a. The covered area of factory buildings and other ancillary
structures such as warehouses and workshops.
b. Internal roads, paking areas, footpaths, loading and
unloading space, and garden area.
c. Fire gap and fire escape routes.
d. Space and locations within the site for installation
such as gas cylinders, transformers, water tanks, underground water
sumps, treatment plants, storm water drains etc.
If the factory is to be located outside an EPZ or an industrial park,
among other matters, transportation, availability of eating establishments,
adequacy of infrastructure facilities such as power, water, telecommunication
and means of discharging effluents if any, disposal of solid waste and
storm water etc. also should be taken note of.
In addition, prevailing by-laws/regulations in force in
the area of the Local Authority, particularly those pertaining to road
reservations, streetlines, construction of buildings and waste disposal
which would affect the siting of buildings and operation of the factory
should be given due consideration.
BUILDING REQUIREMENTS GENERAL
Factory Buildings and Services
All buildings and services shall be designed and constructed
in accordance with accepted Codes of Practice and in conformity with
the current Factories Ordinance.
Architectural Appearance and Quality
The building and other structures shall be aesthetically
pleasing and of a high standard acceptable to the BOI. Major building
components, type of finishes, (such as external finishes of walls),
electrical fans, extractors, blowers, doors, windows, louvres, lighting
points, air conditioncrs (if any) shall be clearly indicated in the
Final Ground and Floor Levels
Final ground and floor levels of the factory must be fixed
in relation to the surrounding lay of the land, adjoining road levels,
invert levels and location of the nearest manholes in order to ensure
proper surface water drainage and sewage disposal.
No factory shall be over crowded so as to cause risk or
Injury to the workers. The space requirement should be decided upon
taking into consideration the numbers and size of machinery that would
be installed, tables/work benches, bins and other equipment that need
to be accommodated in the production areas, pathways, emergency exits
and temporary storage requirements. The total covered area should take
into account the production area required, stores space, office, canteen,
toilets, service areas, first aid room, fire escape routes, maintenance
space, tool room/(s), workshops, boiler room, treatment plants, etc.
The amount of work space allowed for each worker should
be not less than 400 cu. ft. No space over a height of 14 ft. from the
floor shall be taken into account when calculating this cubic space.
In storeyed factory buildings, in addition to the main
stairway leading to the working area there shall be provided an additional
stairway which would serve as an escape route in case of fire. All stairways
should be provided with railings and the top railing should not be less
than 90 cm high. The completed structure consisting of anchor posts
and railings should be of solid construction and should be capable of
withstanding a point load of at least 90 kgs applied in any direction
at any point on the top rail.
Guarding of wall openings, open-side floors, platforms
All wall openings, open-side floors, platforms and catwalks
should be suitably guarded by means of railing or fencing. Where there
is a hazard of material falling from open-side floors, platforms etc.,
suitable protective measures should be adopted by the provision of toe-boards
or screens of solid construction.
The boundary walls along the perimeter of the site and
the gate shall be 6 ft. high. Prior approval should be obtained for
the location of the gate.
The premises and road frontage should be well landscaped. As many of
the existing trees as possible should be preserved and only those which
need to be removed for buildings should be felled.
Parking Areas and Access
Adequate parking areas and suitable access road should
be provided within the site, so as to avoid parking of vehicles on the
The factory compound shall be provided with adequate security
Minimum of two exit doors in every floor or every big room
should be provided.
All electrical installations shall be carried out to the
satisfaction of the Ceylon Electricity Board.
During the planning stages due consideration should
be given to the expansion programmes of the project so that at later
stages when the layouts are modified or the work force is increased
changes required and the provision of amenities to the increased work
force do not become problematic.
