TOR For the Company Conducting the Training and Geophysical Surveying to Ministry of Energy and Water Resources – Mogadishu, Somalia

Ministry of Energy and Water Resources (MoEWR)

FEDERAL GOVERNMENT OF SOMALIA (FGS)

TOR FOR THE COMPANY CONDUCTING THE TRAINING AND GEOPHYSICAL SURVEYING.

1.0 overall TOR OF THE COMPANY CONDUCTING HYDRO-GEOLOGICAL SURVEY

Conduct hydrological and geophysical survey of underground water in 7 locations. 3sites each location.
Train the 4 engineer members from the ministry about how to use and read ABEM LS2 advance Terameter.
Take to the field the 4 engineers and train them how to put on the VES and teach them interpretation of the VES result.
Detailed description about the training methodology

(Theoretical Teaching Plan and Technical Training Field Plan)

Review of knowledge people have with regard to the hydro-geological conditions in the area, their past experiences and the local ground water information
Review of existing documents with information about the hydro-geological conditions in the area (e.g., information about boreholes and dug wells in the area, topographical maps, etc.), research extensively what other companies have done the area as well as the surrounding locations, and finds all possible secondary information
Review of existing data, topographical maps, satellite images, existing studies and borehole site investigations in the area, geological reports and maps (if available), borehole and surface water records.

2.0 scope of GEOPHYSICAL SURVEYING and the training:

The company is expected to use both secondary and primary data in the exercise, Secondary data will involve desk study of available information/data on existing boreholes, drill logs, reports and maps both those that were successful and those failed, while primary data will be obtained by carrying out Hydro geophysical measurements within the study are using the necessary hydro geological surveying equipment, the new ABEM Terrameter LS2 advance, which has a 3D dimensions and also distinguishes between clays and fresh water by resistivity profiling and possible use of seismic refraction method is recommended for this assignment or equivalent equipment.

The company is supposed to train 4 technical engineers from the ministry of energy and water resource during surveying. The training should be first prioritized and the company must have and prepare a teaching plan and fieldwork plan.

The outcome of the company will be a detailed hydrogeological survey report giving details of the findings and recommendations together with outcome from the training.

4.0 SURVEY APPROACHES REQUIRED:

The hydrogeological/geophysical investigations will be carried out in a multistep approach:

Desk study: Review of existing data, topographical maps, satellite images, existing studies and borehole site investigations in the area, geological reports and maps (if available), borehole and surface water records, etc.
Hydrogeological fieldwork: Detailed reconnaissance survey of project area. (GPS coordinates/P codes, water level measurements, condition of these boreholes, usage and performance where applicable) inspection of geological, geomorphological and structural characteristics of the investigated area; verification of existing data and findings.
Geophysical measurements: vertical electric sounding resistivity profiling and seismic refraction application to confirm the VES interpretation.
Analysis of hydrogeological/geophysical data.
Compilation, analysis, and evaluation of the gathered data and information.
Site selection and reporting.

5.0 REPORTING

The final report to be submitted to Director of the Water Department of the Ministry of Energy and Water Resources of Somali Federal Government and should be approved by the DG of the Ministry and the report will be a comprehensive account of the whole of the Company; it will review the existing literature and other relevant information, such as outcome of the training, satisfaction of the 4 engineers on the training, drilling logs, satellite images, etc. The report shall include grade and final evaluation of the training outcome, all field data, interpretations and justifications, hydrogeological evaluations, conclusions and recommendations relating to the investigated areas. In addition, appropriate maps, diagrams and data plots shall be presented. Of considerable importance will be an objective assessment of the applicability and success of the methods to be applied.

The outline below bullets of contents of the final report will be as follows:

Introduction, review of previous studies and environmental background
Geology and hydrogeology (incl. Inventory of boreholes and other water points)
Methods of investigations, including Geophysical Techniques
Detailed resistivity survey (Wenner & VES) and seismic refraction to delineate the productive aquifer
Aquifer potential; sustainable yield & Water quality
Proposed drilling site
proposed drilling method, and its applicability
Environmental impact and protection
Evaluation and result of the training
Training methodology
Conclusion and recommendations

Recommendations will be given on the most suitable site for borehole drilling, the required depth, water quality, design and installation details, and other relevant aspects. Based on the available hydrogeological and geophysical data, an assessment of the anticipated chances of success shall be made for each individual site.

Also, location and GPS co-ordinate sites will be conformed later.

The deadline for bid submission is: 20 July 2021
Time: 10:00 am
