Abstract
This thesis is on the design of the building
services requirement of a dairy plant. Investigation
of the engineering services problems of four existing
medium scale dairy plants at Kaduna, Funtua, Jos and
Minna showed that the greatest problem of the dairy
industry is sanitation, and the building services
requirement being: Water (cold and hot) services,
sewage disposal, Refrigeration and Airconditioning.
The work therefore tried to optimize the design of
these services based on production capacity of
18,000 litres of milk products per shift of 8 hours.
Factors considered in the design included the number
of people that work in the plant, the processes
that the milk products undergo in the industry which
determine temperatures of the various rooms, the
hot and cold water demand the nature of wastes and
waste treatment, and the refrigeration capacity.
The work investigated pipeline and insulation
problems and specified materials and sizes. The
production capacity and processes determined the
machine and equipment specifications. This in turn
determined the plant layout and manpower requirement
as shown in the organisation chart. The building
services were then designed to suite the plant
layout. Detailed designs of the plant layout and
these building services are shown in Drawings 1 to 6 vi
(folded and attached at the back cover). The various
component designs are illustrated in figures 1 — 43
The design of the storm drainage system is based on
the severest rainfall intensity in Kaduna as shown
in tables 4-13 extracted from the Agro-Meteorological
Bulletin of Nigeria (1980-1983).
