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.


SITE REQUIREMENTS

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 consideration:

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.

Floor Space

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.

Storeyed Buildings

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.
