(85) An outline timescale for the project is shown in Figure 29. To permit a relatively rapid development, it would be appropriate to phase the project in a manner ensuring early completion of critical facilities. Thus research activities may be initiated before the final completion of the whole project. This is particularly critical as the timescale indicates that it may be difficult to complete substantial parts of the construction during the coming dry season (November 1986-June 1987).
(86) A more detailed timescale for the initial phases of the project is shown in Figure 30. This is in the form of a simplified critical path chart, and identifies the significant points in the current implementation. Table 32 defines the critical factors likely to cause delay. Table 33 defines the separate phases and the approximate order of execution of the sub-sections within each phase. These may conveniently, but not necessarily be let out as separate contracts.
Table 32 - Significant delaying factors
| 1 Supply of materials; |
| 2 Completion of soil tests/foundation problems; |
| 3 Completion of land purchase/approvals/registration; |
| 4 Supervision resources in FRI; |
| 5 Specification changes/unclear design detail; |
| 6 Unusual weather conditions; |
| 7 Construction quality, supervision, fitness of construction equipment; |
| 8 Conflicts between separate contractors over scheduling, material supply, security and control. |
(87) The design as defined has been costed using current PWD rates and current estimates for aquaculture components. The outline total is shown in Table 34, compared with the current allocation. Details of the costing are given in Annex G. As this demonstrates, the project is just within the budget if full contingencies are allocated.
(88) In the event that the development costs cannot be contained within the allocation, whether through unexpected site costs, through inflationary effects during the project timescale, or other causes, Table 35 identifies the areas in which some savings may be made. As the bulk of the project cost lies in the residences, an initial reduction in the staff establishment, and the greatest possible use of local staff will have a positive effect on the budget.

Table 35 - Potential project cost savings
| AREA OF SAVING | NOTE | |
| 1) | POND AREA | - Little overall effect on cost |
| - Develop part of ponds only in early stages | - Little overall effect, but could be completed easily later | |
| - Reduce size of S-wall | - Savings in land used, but poorer security | |
| - Supply water from Khal | - Saves supply canal, moderate effect on cost | |
| - Smaller ponds and wall | - Could save some land and construction cost | |
| - Do not install pumps | - Could easily be done later | |
| 2) | LAB FACILITIES | - Slightly more effect |
| - Combine analytical and toxicology/disease labs | - Some savings, though less potential for work; feasible | |
| - Simplify buildings | - Possible; could reduce specification in hatchery and demonstration lab | |
| - Reduce lab sizes | - Not desirable; better have fewer labs of good size | |
| 3) | SERVICES | -Some savings possible |
| - Single field water supply | - Less convenient, but possible | |
| -Reduced level of services | - Possible, if expandable later | |
| 4) | ACCOMODATION | - Greatest effects on cost |
| - Reduce staff establishment | - Reduced capacity, but selection of good staff could compensate | |
| - Recruit more local staff | - Possibly better staff morale | |
| 5) | OTHER | - Variable effects on cost |
| - Reduce administration function | - Greatest effects are on accomodation | |
| - Increase contract supervision | - Possible savings, but needs considerable commitment | |
(89) The actual land area required, as defined on the site layout is summarized in Table 36. Table 37 summarizes the land available in the outline survey area as defined in Figure 31, and shows the areas of the khal and the strip of land lying to the north of the khal, both of which might be excluded from purchasing. The site area should be surveyed as soon as possible, to confirm the accuracy of current site maps and to define ownership of areas required. Where possible, the boundary should be adjusted to conform with existing boundaries of holdings.

(90) A draft call for tender for consulting engineers, with terms of reference and schedule of works if provided in Annex H. Selection would be based on prior qualification and quality of technical proposals. Financial terms would be negotiated with the company or group offering the best technical proposal. A single firm would be employed for the entire contract, including design and supervision, though FRI would normally reserve the right to exclude parts of the terms of reference and schedule of works if necessary.
(91) This would ideally proceed within several weeks of the selection of consulting engineers, with the letting of the first phases of the development, permitting the initial site development to proceed, and preparing the site for building work. Table 38 summarizes some of the critical aspects of selection. This would normally be done on the basis of quoted rates for schedules of work, but should be strongly conditional on evidence of satisfactory work of a similar nature, and evidence of capacity for the work involved on the timescale specified. If possible a similar approach should be adopted to that of the selection of consulting engineers, in that a technical evaluation be the prime selector.
Table 38 - Factors affecting selection of contractors
| - Financial standing, references; |
| - Local experience, base in region; |
| - Record of work at similar scale; |
| - Clients references; |
| - Specific experience in area of contract; |
| - Proven ability to work with other contractors on multi-contract project; |
| - Good project documentation; |
| - Good supervisory and foreman staff; |
| - Good organization of materials supply and quality; |
| - Good record of time and schedule keeping; |
| - Good record of labour management; |
| - Full certification of any skilled trades. |
Note: The first contractor, carrying out site clearing and development will be required to provide site office and temporary storage. |
(92) Details of specifications are given throughout the report, together with further detail in the Annexes. It is expected that design and construction follows good national practice and that materials and workmanship will be subject to testing at any stage.
Some specific recommendations known to be relevant in these circumstances are given in Table 39.
Table 39 - Specific precautions in project development

(93) It is recommended that a capable senior member of FRI staff be allocated as soon as possible to provide the essential direction of the project on behalf of FRI. As this is a significant project of considerable technical diversity, it is essential that a widely experienced and professionally competent individual be given the responsibility, which should be full-time committment for the duration of the project implementation.
