Japan International Cooperation Agency (JICA) Oromia Irrigation Development Authority (OIDA)

The Project for Capacity Building in Irrigation Development (CBID)

Foreword Oromia Irrigation Development Authority (OIDA) is established on June, 2013, as a responsible body for all irrigation development activities in the Region, according to Oromia National Regional Government proclamation No. 180/2005. The major purposes of the establishment are to accelerate irrigation development in the Region, utilize limited resources efficiently, coordinate all irrigation development activities under one institution with more efficiency and effectiveness. To improve irrigation development activities in the Region, the previous Oromia Water Mineral and Energy Bureau entered into an agreement with Japan International Cooperation Agency (JICA) for “The Project for Capacity Building in Irrigation Development (CBID)” since June, 2009 until May, 2014. CBID put much effort to capacitate Irrigation experts in Oromia Region through several activities and finally made fruitful results for irrigation development. Accordingly, irrigation projects are constructed and rehabilitated based on that several Guidelines & Manuals and texts produced which can result in a radical change when implemented properly. Herewith this massage, I emphasize that from Now on, OIDA to make efforts to utilize all outputs of the project for all irrigation activities as a minimum standard, especially for the enhancement of irrigation technical capacity. I believe that all OIDA irrigation experts work very hard with their respective disciplines using CBID outputs to improve the life standard of all people. In addition, I encourage that all other Ethiopian regions to benefit from the outputs. Finally, I would like to thank the Japanese Government, JICA Ethiopia Office, and all Japanese and Ethiopian experts who made great effort to produce these outputs.

Introductory Remarks “Growth and Transformation Plan” (GTP) from 2011 to 2015 intensifies use of the country’s water and other natural resources to promote multiple cropping, better adaptation to climate variability and ensure food security. Expansion of small scale irrigation schemes is given a priority, while attention is also given to medium and large scale irrigation.

In Oromia Region, it is estimated that there exists more than 1.7 million ha of land suitable for irrigation development. However, only 800,000 ha is under irrigation through Traditional and Modern irrigation technology. To accelerate speed of Irrigation Development, the Oromia National Regional State requested Japan International Cooperation Agency (JICA) for support on capacity building of Irrigation Experts under Irrigation Sector.

In response to the requests, JICA had conducted "Study on Meki Irrigation and Rural Development" (from September 2000 to January 2002) and Project for Irrigation Farming Improvement (IFI project) (from September 2005 to August 2008). After implementation of them there are needs to improve situation on irrigation sector in Oromia Region.

JICA and the Government of Ethiopia agreed to implement a new project, named “The project for Capacity Building in Irrigation Development” (CBID). The period of CBID is five years since June, 2009 to May, 2014 and main purpose is to enhance capacity of Irrigation Experts in Oromia Region focusing on the following three areas, 1) Water resources planning, 2) Study/Design/Construction management, 3) Scheme management through Training, On the Job Training at site level, Workshops, Field Visit and so on and to produce standard guidelines and manuals for Irrigaiton Development.

These guidelines and manuals (Total: fourteen (14) guidelines and manuals) are one of the most important outputs of CBID. They are produced as standards of Irrigation Development in Oromia Region through collecting different experiences and implementation of activities by CBID together with Oromia Irrigation Experts and Japanese Experts.

These guidelines and manuals are very useful to improve the Capacity of OIDA Experts to work more effectively and efficiently and also can accelerate Irrigation Development specially in Oromia Region and generally in the country.

Finally, I strongly demand all Irrigaiton Experts in the region to follow the guidelines and manuals for all steps of Irrigation Development for sustainable development of irrigation.

I. Outline of Construction Control 1. Purpose

As usual, construction phase is one of the main steps in irrigation project. The purpose of this manual is to summarize basic construction controlling mechanisms by the supervisor. This manual is developed based on experiences gained from Bura Spate Irrigation Project, Hirna Irrigation Project, Sokido Irrigation Project and Shaya Irrigation Project. The manual focuses on how to control construction work to construct structurally safe, hydraulically efficient, and economically viable facilities such as Headworks, Main canal, etc within the construction time schedule. Due to the nature (short and only small construction works) of the project, there are items which need to be improved and incorporated in this manual. And thus this manual should be revised continuously.

2. Basic Composition of Construction Control

Basic construction control items explained in the manual are: Excavation Control Headworks construction control Canal construction control

At the Construction sites of Oromia Irrigation Development Authority, above three items are the major. So, in this manual, these three items are explained. It is necessary to add other items for other type of works.

3. What a supervisor has to do (1) Read and understand the Project document

Having good design concept is very important for on site design change approval. Therefore supervisor should have good experience in design concept.

(2) Read and understand the Bid document Understanding the content of contract document is very important for supervisor in project supervision work to minimize future claim in construction and the corresponding amendment of contract etc.

(3) Provide all drawings on the site For checking or follow up of the construction work having drawing on hand (at the site) is very crucial for supervision.

(4) Make the contact list with contractor and check the work schedule. Communication and checking work schedule is important for progress of construction works.

(5) Proper direction (job order) at proper time This is the most important matter for construction control. For this, above (1) ～ (4) are needed.

Work Item Description Control Point3.7 Concrete work3.7.1 Concrete Materials (1) Cement

1) The cement used in the work shall be ordinary Portland cement as much as possible.

Properties of cement: Cement mortar or concrete has high compressive (crushing) strength, but relatively low tensile (stretching) strength. Within an hour (depending upon temperature and mix) the cement begins to set, losing its plasticity. Within 4hours it has finished setting and can no longer be worked. From the time that setting begins, the cement is undergoing a chemical hardening process which will continue for at least a year, although it most rapidly hardens during the first few days. STRENGH OF PORTLAND CEMENT CONCRETE (percent of ultimate strength at various ages) 3days……………………………………….approx. 20% 7days……………………………………….approx. 45% 28days……………………………………...approx. 60% 3months……………………………………approx. 85% 6months……………………………………approx. 95% 1Year………………………………………..approx.100%

STORAGE OF CEMENT Cement easily absorbs moisture from the air, and as a result loses strength during long period of storage. Typical losses are as follows.

Period of storage Loss of strength 3 months 20% 6 months 30% 12 “ 40% 24 “ 50%

Work Item Description Control Point (2) Aggregate

Aggregate is the general term for the material mixed with cement and water to form concrete. Sand is a fine aggregate, and larger material is a coarse aggregate. Aggregates must be clean and well graded. Smaller rounder aggregates (such as river gravel) are better for water proof floor slabs. Sizes of Aggregates Aggregates should be well graded so that air voids between pieces are minimal. The greatest dimensions of the aggregate are as follows. 1) The greatest dimensions of the aggregate sets it

in consideration of the space of material dimensions and the space of reinforcing bar.

2) The greatest dimension of the aggregate must not be beyond 1/5 of material smallest dimensions, 3/4 of the smallest space of the reinforcing bar and protective covering. In addition, the greatest dimension of the aggregate of the reinforced concrete is 20mm or 25mm.If the section is big, the greatest dimension of the aggregate is 40mm.In the case of plain concrete, the greatest dimension of the aggregate is 40mm or must not be beyond 1/4 of material smallest dimensions.

3) As for the greatest dimension of the aggregate, the following is a standard.

Structural requirement The greatest dimension of the aggregate

3/4 of the smallest space of the reinforcing bar and protective covering >40mm

40mm

Case except the above 20mm or 25mm Aggregate which are likely to cause alkali-aggregate reaction in the concrete shall not be used. Fine aggregate shall consist of natural sand. Sand is used in both mortar and concrete (in the later it is sometimes referred to as “fine aggregate”. Proper sand is well-graded (i.e. containing grains of many sizes mixed together. Sand of a uniform size, such as beach sand or very fine sand is not suitable (but can be mixed to coarser sands.))) Quality Sand containing clay, silt, salt, mica, or organic material is not good, since such contaminants can weaken if they are present in large quantities. See IV.6. Concrete Test (3) Grading and Quality Test for the detail. (3) Water Water shall be fresh, clean and free from injurious amount of oil, acid, alkali, salt, organic matter or other deleterious substance. But it is difficult to analyze water quality in the laboratory for every irrigation project because of limitation of the cost and the time. So water shall be used clean river or drinking water as much as possible.

Control Item Control Process / DescriptionConcrete work7. Concrete Placement Works - A use of inclined chute shall be

avoided as much as possible . - The maximum falling height is 1.5m. Placing concrete: A bucket of concrete should never be dumped from any height since segregation of the aggregates will occur. Segregation: This is the segregation (due to gravity) of aggregates in the concrete. The heavier aggregates will tend to sink to the bottom, and water will rise to the surface. This is a poorly mixed concrete which will be weak. Segregation usually happens transporting the concrete from the mixing pad to the work site. Therefore the mixing pad should be as close to the final pouring point as possible, and the concrete should be re-mixed with a trowel before pouring. Compacting: This is the process of setting the concrete so that it contains no air voids. This is accomplished by “rodding” the concrete, poking a length of re-bar into the concrete and stirring it up and down at all corners and around reinforcement. After rodding, the concrete should be tamped level again, using a flat board of wood

- The concrete shall not be moved to horizontal direction .

- The concrete shall be placed to the backward but not to the forward .
