(48) The overall building areas defined in the original project proposal (PP) are summarized in Table 21. This is used as the basic quantity for site area requirements and budgeting control. Thus, allowing for a 40 % additional space factor, the total land area required is 4617 m2 at the minimum.

(49) To identify more closely the actual requirements of the individual research areas, outline building layouts were defined. These were not derived directly from the areas and specifications of the original PP and the subsequent research planning documents, but rather built up from a definition of the important laboratory functions and their appropriate sizing. The plans drawn up, described in the following sections, show separate units, all of single storey construction, through they may in practice be grouped into one or more centres. Table 22 defines the actual laboratory areas.
(50) Suggestions are made on methods of construction; through this is finally at the discretion of FRI, as advised by the consulting engineers preparing the detailed design. It is important to note:

(51) There are four laboratory building units, each of a standard 300 m2 size: 12 m × 25 m. A pitched roof is shown in the outline designs (Figures 17 – 22), but is not essential. Two of the buildings, an analytical laboratory and a toxicology/pathology laboratory are of full specification, while two, the hatchery laboratory and demonstration laboratory can be of simpler ‘field’ construction. Each unit is essentially self-contained; services are described in the next section. It is intended that scientific staff be based in the buildings themselves, and office space is provided accordingly.
(52) Analytical laboratory: this unit (Figure 17) is designed to provide facilities for water and soils analysis, local feed preparation and basic analysis (it is assumed that main nutrition facilities will be at Mymensingh), and biological analysis. A generously sized wet laboratory for keeping stocks, field samples and experimental animals is provided, and a verandah area is extendable to provide space for feed preparation and for additional tankage if required. Specific areas are also provided for reception and primary treatment of field samples. There are two special facilities: a room for sensitive analytical equipment, and a cold store/freezer for frozen storage of any materials.
(53) Toxicology/pathology laboratory: this unit (Figure 18) provides facilities for analysis of disease and environmental problems in farmed stock, and also provides for any quarantine requirements, if stocks are to be brought in from other regions or moved onwards. A generous provision of wet laboratories is made, together with separate laboratory areas for preparation of samples, bacteriology, parasitology and histology.
(54) Hatchery laboratory: this laboratory (Figure 19) provides for spawning, fry rearing and feed growing facilities, with extensive open access to further exterior tankage. The sizing of the hatchery facilities is based on Penaeus production, but is equally suitable for Macrobrachium and/or marine fish (see Annex C). The facilities on this laboratory are essentially production oriented rather than research oriented, but the provision of excess space and tankage allows considerable flexibility.
(55) Demonstration laboratory: this facility (Figure 20) is essentially a field laboratory, with facilities for demonstrating field aquaculture techniques to groups of trainees. The main feature is the open teaching area, with supplementary wet lab, lecture/seminar room and field store/office.
(56) All of the laboratory areas, except for field and outside demonstration areas, require to be furnished to a high standard, with easily cleanable surfaces and well serviced facilities. Ideally all buildings should have the minimum of internal load-bearing walls or columns, to present maximum long-term flexibility of use. All wet laboratories, and the hatchery and demonstration areas should in particular make use of natural ventilation as much as possible. In most areas, a simple asbestos cement or equivalent roof would be appropriate, and in the hatchery laboratory, translucent panels should be provided in the hatchery areas and the main algal and zooplankton culture areas. Table 23 summarizes the level of specification suggested for the different units of BFRS.
Table 23 - Specification levels
| LEVEL | CHARACTERISTICS | AREAS |
| 1 | Completely sterilizable, tiled or sealed surfaces, pipework can be dismantled, sterilized, high level of power, light, drainage. Limited access to lower category areas. Possible climatic control. | Algal stock, starter preparation room, Microbiology preparation room. |
| 2 | Easily cleanable, tiled, sealed surfaces, moderately high level of power, light, drainage. | Sample intake areas, wet labs, algal, zoo- plankton culture areas, toilets. |
| 3a | Standard laboratory specification. Good level of services. Controlled ventialation/climate. Easily cleanable, not necessarily sealed, though specific areas could be so. | Special equipment laboratory, hatchery laboratory. |
| 3b | As above, without climate control. | General laboratory areas. |
| 4 | Standard office specification. Power, light. | General office areas, class, seminar rooms. |
| 5 | Field laboratory standard, semi-open areas, reasonably cleanable, sealed floor, good drains, power, water supplies. Simpler construction standards possible. | Demonstration lab, hatchery spawning area, feeds preparation, workshops. |
| 6 | Basic covered space, power, light, optionally lockable, earth or low grade concrete or gravel floor. | Stores, open tank spaces. |

Figure 23 - Building layout
(57) Services centre: this unit is sized as the laboratory buildings (Figure 21) and is designed to accomodate all the engineering and services facilities within the area. The building houses garage, workshops, generators, air blowers, water treatment, and engineering offices and stores. Construction can be similar to that of the other buildings, but internal finish does not have to be to similar standard. If functional units are to be grouped together in the final design, it would still be advisable to separate at least the generator and garage areas from other activities.
(58) Administrative building: this building (Figure 22) provides the main administrative offices plus library and meeting/conference room facilities. The double unit shown is based on a slightly smaller unit module than the others: 200 m2 or 10 × 20 m, the total area being approximately 450 m2.
(59) Residential buildings: these are not specifically developed in layout, being standard specification residential units, for which many appropriate designs are available locally.
(60) A typical layout of the building units is shown in Figure 23, though this is for illustrative purposes only. In practice many options exist for the design of the buildings, and it is not strictly necessary to separate the laboratories as described, particularly if cash savings can be made. Of particular importance however is the identification of critical design constraints, which have been taken into account in the above layouts, but which may not be explicit. These are summarized in Table 24.
Table 24 - Critical building design factors
| - Specified unit dimensions should be followed where possible; buildings should be laid out for maximum flexibility of use, and ease of further development; |
| - Laboratory offices should be adjacent to related work areas, and should ideally open out into them; |
| - Facilities such as the specials laboratory, cold store, sample reception areas, stores, cleaning and preparation areas are common to several laboratories and should be easily accessible to them; |
| - Stores should be provided in each major functional area; |
| - Sensitive areas - algal stock, starter cultures, quarantine areas, microbiology area, disease holding area - should be separated from general use areas; |
| - Toilets should be reasonable available and accessible, but should not be adjacent to sensitive areas; |
| - Laboratories should be easily ventilated if required, should have good storage and working areas, and should be well lit with natural light if possible; |
| - Access should be provided for intake of field samples of fish, shellfish, water, soils, feeds, ideally separate from main laboratory areas; |
| - Public access should be restricted to specific locations, and should not be available to sensitive areas; |
| - All laboratory areas should be well-serviced, with adeqate and well-placed power points, water supplies, drainage, and lighting; |
| - Special storage should be available for dangerous and/or imflammable materials. |
