and non-ferrous foundries) where adequate ventilation is the problem; and all food processing, because the simple design of the buildings and the proximity of other trades preclude maintenance of the necessary standards of hygiene.
94. Though a higher rent is charged for ground floor units, their case of access makes them more popular than those on upper floors. Trades that require the heaviest floor loading have priority for ground floor units.
95. Resettlement factorics are not easy to administer. The accom- modation is of a relatively high standard, is available in small units and is cheap compared with the alternatives available in the open market. There is therefore a temptation for factory tenants to sublet their premises to outsiders under the guise of installing a manager. This is particularly attractive to those tenants who have had, usually unwillingly, to change their trade in order to qualify for resettlement. Where subletting occurs, the rent is always higher than that charged by Government. Permitted transfers of tenancy to any other domestic or business tenant of the department are also quite frequent because of the inducement contained in the transfer fee, supposed to cover the cost of decorating the units, which the transferee customarily pays the transferor. The installation of machinery has to be carefully regulated to take floor loading and electrical safety into account. Changes of trade, or of tenancy, usually mean a change of machinery, in whole or in part, and since some tenants tend to install machinery without obtaining prior approval, control of machinery is a constant problem.
96. There have also been difficulties in supplying enough electricity in some factory blocks. On resettlement, tenants tend to replace manually-operated with electrically-operated machinery. Some of the private internal electrical wiring is of a poor standard. Overloading of the electrical supply has resulted, with consequent breakdowns. It has therefore been necessary since June 1965 to install additional rising mains in several factories over the past few years, and to install moulded circuit breakers for each tenant. The cost of these improve- ments will be charged to the tenant in relation to the amount of electricity he requires. By this means, breakdowns in supply will be localized in the factory unit at fault and will not affect the whole floor or block.
