ERA Awards the Most Expensive Road Project

Sponsered Links

 

 

The Ethiopian Roads Authority (ERA) has signed an agreement with Rama Construction Plc for the construction of the so far most expensive road project at a cost of 69.2 million Br a kilometre.

The road, extending from Azezo-Gonder, covers 12.6 kilometres and will be constructed at a total cost of 871.6 million Br. The project takes the place of the Melka Jebdu – Dire Dawa road projects, which cost the Authority 63.5 million Br per kilometre. Nevertheless, the road is three times less expensive than the most expensive highway road project, Qality Interchange – Tulu Dimtu Highway.

The Azezo-Gonder road has two lanes with a 10.6 metre width on each side, accommodating six cars at once. The lanes have 2.5 meters of dividing section (central reservation). The road also has sidewalks on both sides, stretching three metres each. It also has three bridges as well as 34 drainage pipes. It is expected to be completed within two years.

The contract was signed between Araya Girmaye, director general of ERA, and Ferew Tedla, managing director of Rama, on May 23, 2017, at Hilton Addis Hotel. Rama previously executed Tsegede Junction – Ketema Nigus upgrading road project, according to Daniel Shiferaw, road and industry coordination department manager at Rama.

The project was signed along with 18 more new road projects located in five regional states. Out of the total 19 road projects, 12 of them were awarded to local contractors, while the remaining are to be constructed by Chinese companies.

These 19 projects cover a total of 1,007 kilometres, raising the number of road projects awarded to contractors to 50, costing the government 43.4 billion Br. The construction of these roads will create job opportunities for 25,000 people.

This contract signing ceremony is a record high in terms of the number of projects signed in a day. Two years ago, the Authority awarded 13 projects in a single day, which was the highest until the signing of the new projects, according to Samson Wondimu, communications director at ERA.

Among the 16 contractors that won the right to construct the projects, Sur Construction, Bridge Construction Plc, Rama, Aser Construction Plc, Zongmei Engineering Group, China Gezhouba Group, and Shandong Highway Construction have previously worked with ERA.

On the other hand, Tekleberhan Ambaye Construction, Eshetu Lemma Road Construction, Jiangxi Water & Hydropower Construction and China Railway 21st Bureau Group are working with ERA for the first time.

The consultancy for 17 road projects is not yet decided as it is in the bidding process. SG Consulting Engineers and Net Consulting & Architects are selected to supervise two of the projects. The former supervise the 36 kilometres long Babile-Fik road project constructed by Yotek construction, at the cost of 447 million Br. Net Consulting worked on the 30.5 kilometre long Bole Junction- Weteredno flower plantation development constructed by Eshetu Lemma Construction at a cost of 360 million Br.

Apart from the 19 projects, an agreement for a feeder road project in Hosena was meant to be signed with Yosef Teketle General Contractor on the same day, but the agreement could not be signed because the documents of the accord were not fulfilled, according to Samson.

Zongmei Engineering Group won the least expensive road project at 7.4 million Br per kilometre to construct the Ambo to Gedo Asphalt.

Passanger Terminals to be constructed for Semera & Hawassa Airports

The Ethiopian Airport Enterprise (EAE) has signed a 276 million Br contract with two local companies to complete the construction of passenger terminals at Semera and Hawassa Airports.

The Enterprise contracted two companies, Afro Tsion Construction and FE Construction Material Rental Production & General Contractor Plc, to finalize the projects in less than a year.

 

The signing between the CEO of the Enterprise, Tewodros Dawit, and the representatives of the two contracting companies, was held at the Enterprise’s premises near Bole International Airport, on February 3, 2017. FE Construction was awarded the contract for the Hawassa terminal at a cost of 126 million Br.

sponseerd link

The company was established in 2000 with 300,000 Br capital. This is the first time FE has worked with the Enterprise, although the company currently has projects with Dire Dawa and Bahir Dar Universities. It has more than 20 projects worth almost three billion Birr and has over 500 permanent employees.

The construction of the Hawassa Terminal was preceded by the completion of the runway. The Hawassa Airport started services four months ago; the runway cost was just over half a billion Birr. The airport has the capacity to serve three Boeing jets, including the Boeing 777, and was constructed by YOTEK Construction Plc.

“The terminal was supposed to be constructed with the runway,” said Tewodros. “However, it suffered delays because of a lack of external financing. We decided to use our own budget in the end.”

YOTEK has almost completed a five-kilometre stretch of the 25km asphalt road connecting the airport with the city of Hawassa under its agreement with the Enterprise. However, the construction on the remaining 20km, which will be contracted under the Hawassa City Administration, has still not been awarded.

The Hawassa Airport opened in the midst of the development of an industrial park in the city. The park serves global companies in the garment and apparel industry, such as the America-based Van Heusen (PVH) – owner of popular brands such as Tommy Hilfiger, Calvin Klein and Vanity Fair, Indian apparel maker Raymond Group and Arvind Ltd, as well as local companies.

Afro Tsion won the contract to build a passenger terminal at Semera Airport for 150 million Br. The project is expected to be completed in less than a year. It also won the contract for the runway. In August 2016 it was announced that most of the work of the airport had been completed. The Airport serves travelers going to and from Afar Regional State, and tourists to the Ertale volcanic site and the Danakil depression. Established in 1998 with a capital of 50,000 Br, the company is also constructing the runway for Jinka airport.

“We have already finalized the earth work and we are preparing to start asphalt work,” said Sisay Desta, CEO and founder of Afro Tsion Construction.

Each of the two terminals will have the capacity to serve up to 130 passengers at once.

Currently, the Enterprise is constructing five projects including Robe, Jinka, and Shire airports.

At the end of the timetable of the second edition of the Growth and Transformation Plan, the Enterprise has set a target to increase the number of airports in the country from 25 to 30.

Third Expressway to be constructed

Sponsered Links

The Ethiopian Roads Authority (ERA) is considering only Chinese companies for the construction of the nation’s third expressway, which will extend the Addis-Adama Expressway, with an estimated cost of 12 billion Br it secured from the EX-IM Bank of China.

For the project, the Authority re-announced a non-inclusive tender, only inviting Chinese construction firms. ERA announced the tender on June 1, 2017, in the daily state newspaper, The Ethiopian Herald.

The government has already secured the finance for the 120km project from EX-IM Bank of China. The road will be an extension of the 84.7km Addis-Adama Expressway.

The first bid was announced in July 2016 but it was subsequently cancelled as the Authority believed the offers made by the companies were highly inflated, according to Samson Wondium, communications director at the Authority.

The road will have two lots; the first lot extends from Adama to Wolnchiti, covering 60km, and the second will extend from Wolnchiti to Awash, having a same length of 60km. The roads will pass through Amhara, Oromia and Afar regional states.

This expressway is part of a project that the Authority plans to construct from Adama to Messo town through Awash, all located in the eastern part of the country, with a total length of 202.5km and an estimated cost of  20.2 billion Br. ERA divided the project into three phases, the first starting on the outskirts of Adama destined to reach Dire Dawa.

The announcement invites companies to design and build the expressway. The project will also include link roads, overpass bridges, underpasses, interchanges and toll plazas.

It also requires the companies to have a five-year experience in constructing expressways and have an annual turnover of three billion Br.

“Since we secured the finance last year from China, we invited only Chinese companies, which have a vast experience in the area,” said Samson.

To conduct a preliminary study and assessment of the project, ERA hired a Chinese company, Beijing Expressway Supervision, and an Ethiopian firm, Beza Consulting Engineers Plc, for 41.1 million Br in 2013. The two companies submitted the study in 2015. They found that an estimated cost of the project was 100 million Br per kilometre. But this cost might inflate, as the study was done two years ago and while working on the detailed design of the road.

This expressway is expected to cut the drive from Adama to Awash by half, according to Samson.

The new road will be an extension of the county’s first ever expressway, which was inaugurated three years ago. China Communications Construction Company (CCCC) build the six-lane Addis-Adama Expressway at the cost of 11 billion Br. The 25pc of the cost was from the government’s offer while EX-IM Bank of China financed the balance amount in a loan arrangement.

The second expressway, extending from Modjo to Hawassa, is underway with an estimated cost of 700 million dollars. The 218km road is divided into four phases, and the construction of one of the phases kicked off in 2015, at a cost of 3.6 billion Br. Covering 72km, the project was awarded to Chinese Railway No.7.

For the second phase of the Growth & Transformation Plan (GTP II), the country targets to construct a 761-kilometre highway, including the Adama to Awash Expressway. The country’s road network has reached over 110,414kms and is targeted to reach 220,000kms in the coming three years.

Upon completion, the Adama to Awash expressway project will facilitate the logistics from Djibouti to Addis Abeba, according to Samson.

On a daily basis, over 22,000 vehicles pass through the Adama to Awash road, which serves as a gate for over 90pc of the country’s import and export volume, according to data from ERA.

The Addis-Adama project is the most expensive expressway  so far with 131 million Br a kilometre, which is 91 million Br lower than the most expensive road project to date, Qality-Tulu Dimtu Highway. The Adama-Awash Expressway follows it with an estimated cost of 100 million Br a kilometre, and Modjo-Meki comes third with a cost of 48.6 million Br a kilometre.

The financial opening of the Adama to Awash project will be held in July 2017.

A study by the Federal Ethics & Anti-Corruption Commission (FEACC), points fingers at the Ethiopian Roads Authority’s (ERA) contract awarding practices, for being vulnerable to corruption and cost and time overruns

The Commission, which presented its research findings at a meeting called on June 10, 2015 at Ghion Hotel, came to this conclusion after finding gaps in 20 ERA projects it assessed.

 

Among these were tendering procedures, particularly the way road projects are awarded to companies without considering their track record, causing time and cost overruns and also compromising the quality of each road constructed by a single contractor.

The study listed 12 road projects, including Adura-Akobo, Adura-Burabi, Salwa-Maji and Salwa-Maji-Laska, constructed by a single contractor, as an example of this practice.

From a legal standpoint, it is not at all a crime to have two companies: contractor and consultant on several projects, but their past performance must be considered, said Aklilu Mulugeta, corruption prevention director at FEACC.

Moreover, the study also indicated that ERA has weaknesses in its supervision of each and every project and in the monitoring of their progress.

sponseerd link

It also stressed the fact that there are few bidders competing to undertake road projects, owing to the complexity of competitive bidding procedures, and the failure of the Authority to widen alternatives for increasing the number of bidders. That problem contributed to the exaggerated cost of road projects.

Another point that was given due consideration in the study was costly road design problems.

Specifically, the case of the Adiremet-Dejena-Dansha road project illustrated this. According to a recent study done by the Construction Sector Transparency Initiative’s (COST) Ethiopia office, the project, a 97Km road construction in north-western regions of Tigray, was scheduled to be completed in February 2012. However, only three quarters of it was completed as of October 2014. The hold-up in schedule cost the Authority an additional 274 million Br from the originally projected cost of 980.7 million Br.

According to the report by COST, lack of transparency, prolonged procurement, design modification and limited capacity of the contractor, were attributed as major problems.

A third report done by the research directorate of ERA under the title, Causes of Time and Cost Overrun on ERA Road Construction Projects, based on 56 road projects constructed and completed between 2006 and 2015, found out that eight had faced cost overruns, eleven, time overruns, while 37 faced both.

The Commission finally recommended that the Authority award projects to companies in the construction sector, based on their former results. It also recommended that ERA implement a design auditing system in order to make companies and individuals accountable for their actions, such as poor designs.

It was also recommended by the Commission that ERA filter projects that have gaps in terms of resource wastage, and take administrative and legal action.

“We accept all the recommendations and we have been working on it for the past four years, designing 16 projects in order to basically deal with increasing the number of consultants and contractors, capacity building in design works and right of way issues,” said Samson Wondimu.

Fun Facts about Skyscrapers

The Eiffel Tower

The Eiffel Tower was the tallest building in the world when it was completed in 1889. It was built for the World’s Fair to demonstrate that iron could be as strong as stone while being dramatically lighter. And in fact the wrought-iron tower is twice as tall as the masonry Washington Monument and yet it weighs 70,000 tons less! It is repainted every seven years with 50 tons of dark brown paint.

sponseerd link

The Home Insurance Building

Called “the father of the skyscraper,” the Home Insurance Building, constructed in Chicago in1885 (and demolished in 1931), was 138 feet tall and 10 stories. It was the first building to effectively employ a supporting skeleton of steel beams and columns, allowing it to have many more windows than traditional masonry structures. But this new construction method made people worry that the building would fall down, leading the city to halt construction until they could investigate the structure’s safety.

The Chrysler Building

In 1929, auto tycoon Walter Chrysler took part in an intense race with the Bank of Manhattan Trust Company to build the world’s tallest skyscraper. Just when it looked like the bank had captured the coveted title, workers at the Chrysler Building jacked a thin spire hidden inside the building through the top of the roof to win the contest (subsequently losing the title four months later to the Empire State Building). Chrysler also decorated his building to mirror his cars, with hubcaps, mudguards, and hood ornaments.

The Empire State Building

The Empire State Building is designed to be a lightning rod. In fact, it is struck by lightning about 100 times each year!

Citicorp Center

New York’s Citicorp Center (915 feet tall, 59 stories, built in 1977) was the first U.S. skyscraper to contain a tuned mass damper in order to control the building’s sway. The structure was also the site of a near catastrophe. During construction, instead of welding joints as originally specified, builders bolted them. A year after completion, with hurricane season fast approaching, the building’s chief engineer discovered the change and realized the joints would be too weak to withstand hurricane-force winds, potentially leading to the building’s collapse in a dense urban neighborhood. To correct the problem, a team of workers was hired to weld two-inch-thick steel plates over each of the 200 bolted joints. Six weeks into the three-month repair job, Hurricane Ella was off the coast of North Carolina, headed for New York. Luckily, just hours before New York City was to face emergency evacuation, the hurricane veered out to sea. This crisis was kept secret from the public for almost 20 years.

The Petronas Towers

In the Petronas Towers, the shape of the floors is based on an eight-point star, common in Malaysian Islamic patterns. The towers have so many windows that window washers take a month to clean each tower! You can get an up-close look at the building in the movie Entrapment, starring Catherine Zeta-Jones and Sean Connery.

John Hancock Center

In order to strengthen the John Hancock Center against Chicago’s famous winds, engineers included five enormous diagonal braces on the exterior walls of the building. These diagonals block the view from two windows on each floor. A clever rental agent, however, has made these sightless windows a status symbol and it actually costs more money to rent these rooms!

First Interstate World Center

First Interstate World Center (Library Tower) in Los Angeles is located just 26 miles from the San Andreas Fault and has been designed to withstand an earthquake of 8.3 or more on the Richter scale, with a massively reinforced central core and lighter columns around the perimeter. This design makes it flexible, so it can resist vigorous side-to-side shaking without snapping, yet stiff, so it can withstand the force of the wind.

The Sears Tower

On a clear day, you can see four states from the top of Chicago’s Sears Tower: Illinois, Indiana, Wisconsin, and Michigan. To make sure your view is clear, the building features six robotic window-washing machines mounted on the roof.

Taipei 101

Taipei 101 is comprised of 101 stories and reaches 1,667 ft (509 m) high. It was ranked as the world’s tallest building when it was topped out in 2003, but lost the title in 2010 to the Burj Khalifa (formerly called the Burj Dubai). A 660-ton pendular mass damper helps the skyscraper withstand tremors from earthquakes and typhoon winds.

Burj Khalifa

Burj Khalifa, in Dubai, United Arab Emirates, was completed in January 2010 and became the world’s tallest building at 2,716 feet (828 meters) and 160 stories. It contains the world’s fastest elevators, 20.7 acres of glass, and is expected to use about 250,000 gallons of water per day.

Chemical Admixtures

sponseerd link

Chemical Admixtures

Admixtures defined as material other than water, aggregates, and hydraulic cements used as an ingredient of concrete or mortar and added to the batch immediately before or during mixing.

Most of the time Mineral admixtures are used to improve workability and durability and to harden concrete.

Chemical Admixture is defined as a chemical other than cement, water; aggregate that is used as ingredient of concrete to improve properties Such as workability, curing temperature range, setting time or color.

Some chemical admixtures have been in use for a very long time such as calcium chloride to provide a cold-weather setting concrete. Others are more recent and represent an area of expanding possibilities for increased performance. Although many new compounds of are being developed for use in concrete, chemical admixtures and mineral admixtures are derived from waste products from other industries, and as such may be complex mixtures of compounds. Thus the chemistry of concrete chemical admixtures is complex topics required in –depth knowledge and experience.

The effectiveness of an chemical admixture depends upon factors such as type, brand, and amount of cementing materials; water content; aggregate shape, gradation, and proportions; mixing time; slump; and temperature of the concrete.

Generally the cost effectiveness of a chemical admixture should address the additional cost required to handle an additional ingredient, as well as the economic effect the chemical admixture may have on the cost of transporting, placing and finishing the concrete.

1.      Types of Admixture

Generally Admixtures divided in two major categories; Chemical admixture and Mineral admixture of concrete.

Mineral admixtures are minerals added Portland cement mix approximately > 15% by weight of cement like raw or calcined pozzolans; Fly ash produced from burning bituminous coal; Fly ash normally produced from burning lignite (subbituminous) coal both pozzolanic and cementatious.

Chemical Admixtures usually added to Portland cement mix about1-4% by weight of cement.

There are different means to classify admixture type that are available in the construction industry among these the two common ways of classification is based on the state of admixture and based on the function they give.

1.1.            Classification Based on the State of Chemical Admixture

There are different means to classify admixture type that are available in the construction industry among these the two common ways of classification is based on the state of admixture and based on the function they give.

Two classes of admixtures are available based on the form of admixture these are

  1. 1)Admixtures in liquid form

Usually Chemical admixtures which are manufactured in industries aligned with research and frequent experiments made for specific use to assist or to create particular behavior of concrete.

  1. 2)Admixtures in powder form

Most of the time mineral admixtures found in surface of the earth or manufactured in industries to make concrete more helpful.

Some of such admixtures pre-mixed with Portland cement like; Pozolana and colored cements which are added in cement manufacturing plants in specified proportion.

 1.2.            Classification Based on the functions

Admixtures can be classified by function as follows:

1. Air-entraining admixtures

2. Water-reducing admixtures

3. Plasticizers

4. Accelerating admixtures

5. Retarding admixtures

6. Hydration-control admixtures

7. Corrosion inhibitors

8. Shrinkage reducers

9. Alkali-silica reactivity inhibitors

10. Coloring admixtures

11. Miscellaneous admixtures such as workability, bonding, damp proofing, permeability reducing, grouting, and gas-forming, ant washout, foaming, and pumping admixtures

1.3.            Classification Based on ASTM

ASTM C 494, “Standard Specification for Chemical Admixtures for Concrete,” classifies admixtures into seven types. ASTM classifies Chemical admixtures based on their purpose; stated as follows:

Type A: water-reducing

Water-reducing, set-controlling admixtures are added to concrete during mixing to increase workability, improve durability, provide easier placement, control the setting time, and produce easier finishing with less segregation of the ingredients.

This is accomplished while allowing a reduction of the total water content and providing the ability to control the time of setting to meet changing jobsite and climatic conditions.

The strength improvement resulting from water-reducing admixtures is primarily a result of reducing the watercementitious materials ratio and increasing cement efficiency. For a given air content, concrete strength is inversely proportional to the water-cementitious materials ratio and, therefore, the reduction in water needed to achieve the desired slump and workability when a water-reducing agent is used will effect an increase in strength. The result of waterreducing admixtures in improving strength, however, often exceeds the results of simply reducing the water content.

Type B: retarding

Type C: accelerating

Type D: water-reducing and retarding

Type E: water-reducing and accelerating

Type F: high-range water-reducing

Type G: high-range and retarding

1.4.            Commonly Used Chemical Admixture in Ethiopia

Chemical admixtures are designed to enhance the properties of concrete or mortar in the plastic and hardened states, increase efficiency of cementitious material, and improve the economy of the concrete mixture. The use of a chemical admixture or combination of chemical admixtures may be the only viable strategy to achieve the desired results. In certain instances, the desired objectives may be best achieved by changes to the mixture proportions in addition to using the proper chemical admixture.

The most frequently used chemical admixtures in Ethiopia can be categorized in to three classes of chemical admixtures based of their functional used in the site. Each of the categories are discussed in detail below.

  1. 1)Accelerators these are used to increase the rate of setting or the rate of hardening at early age or both effects simultaneously. These type of chemical admixture most of the time used by general contractors and real estate developers for the following reasons

ü  To increase the progress of concrete works which helps in reduction of completion time of the project and effective use of form works.

ü  For the productions of blocks and precast elements

`2) Water-reducing and set retarding chemical admixtures to reduce the water requirement of concrete or to retard the setting time of the concrete or both. Most of the time these types of chemical admixtures are applied for long hauling of ready mix concrete in hot temperature and for the placement of massive concrete.

3) Damp proofing acts to make the surface of pores no wetting that means they increase the contact angle of water with pores surface. This will increase the external force required to over comes the surface forces and penetrate the pore. These types of chemical admixtures are suitable for masonry or concrete structures subjected to hydrostatic water pressure such as culverts, canals, manholes water reservoirs and basements.

1.5.            How to select chemical admixtures

Most of the time there are many basic reasons to consider while using chemical admixtures; but first one have to see what concrete have by its own. Then try to list out special conditions encountered and list what are special properties to encroach. There are many misleading promotions one has to be aware of.

Some of points to considerer while selection types of admixture    

  1. 1.Workability
  2. 2.Bleeding and Settlement
  3. 3.Consolidation
  4. 4.Hydration, Setting Time, and Hardening
  5. 5.Curing
  6. 6.Drying Rate of Concrete

  17. 17.Sulfate Attack
  18. 18.Seawater Exposures
    1. a.Role of Admixture in cement proportion aspect

2.      Merit and demerit of Using Chemical Admixture

 c.Role of Admixture in construction methodology aspect

 d.Role of Admixture in construction cost aspect

 e.Role of Admixture in special concrete production aspect

 f.Role of Admixture in environment protection

3.      Demand and Supply of Chemical Admixtures in Ethiopia

In this time the use and practice of admixtures in Ethiopia is beginning stages, it only accounts two decades. The market availability and utilization of admixture in the country is very small when we compare it with developed countries. This may be due to the recent introduction of the material into the market and lack of awareness toward the importance and use of admixtures.

In these days there are a few companies that distribute admixture by importing from different countries of the world such as South Africa, Saudi Arabia, Germany and Great Britain. Most of the suppliers are located in the capital city, Addis Ababa.

These companies only import those admixtures that are commonly used in the construction industries.

3.1.            Chemical Admixture Practice in Ethiopia

Chemical admixture are applied for the following site works

  1. For ready mix concrete
  2. For production of precast elements
  3. For production of blocks
  4. For concrete structures subjected to hydrostatic water pressure
  5. Other construction works

 3.2.            Admixture suppliers Distributor of Chemical

1. AB-HAM P.L.C Fosroc Admixture

2. Afro Chemicals & Steel P.L.C BASF Admixture

3. Con Mix Addis Ababa Branch Con Mix Admixture

 4.      PRECAUTION IN USE

Special conditions to use Chemical concrete admixture

Storage of Chemical Admixtures

Dosage of Chemical Admixtures

The following points should be considered before using concrete chemical admixture:

  • Follow the manufacturer’s instructions regarding dosage, application details and instructions and product description
  • Make relevant tests to check that the desired effects are being obtained. It is particularly important because the precise effect of a chemical admixture will depend on many factors, cement composition, aggregate characteristics and impurities, mix proportions, presence of other chemical admixture type and length of mixing, time of addition, concrete temperature, and environmental condition.
  • The presence of any potentially detrimental substance such as chlorides, sulfates, sulfides, nitrates or ammonia.
  • Potential occupational hazard for works should be considered
  • Conditions for storage & recommended shelf life

Ethiopian Construction Machinery Rent Rate Drop About 25% from Last Year 2005 EC

Ethiopian Construction Machinery Rent Rate Drop About 25% from Last Year 2005 EC

Those who have no clear picture on the “historical” background of equipment rental rate in the country may consider as the recent “drop” of rental rates for construction equipment as a breaking news. But it would be advisable to look back what the construction industry machinery have come through.

We would like to quote some points regarding Ethiopian Construction Machinery rental rate:

In simple word, the rise or “escalation” on rental rate of construction Machinery does not follow the rise and fall for delivery price of the machineries which is one of the factors dictate any market, as a rule of thumb on many of the business sector. It was only based on shortage in the industry to meet the day to day demand request of the same whereby the business sector has been led by brokers or “DELALA” which highly affected the market uncontrollably and victimize many.

Let’s see form our database how the change for major construction equipments rental business in the last two years.

Excavator (CAT 325 or equiv.)

In our perspective, the mid of 2004 EC was the time when the implementation of URRAP (Universal Rural Road Access Program) was started to be realized by the government. It was primarily planned to be executed in labor base fashion to create job opportunities for many unemployment equivalent to the importance of an all weather road for many parts of the country but the design and the site condition was not favorable to execute as per the original plan and inconsequence the realization of providing an all weather road prevail than the rest of equivalent targets so that the demand of construction equipment became unavoidable. So it was the overturning time that led stake holders in the construction equipment rental business give chance to or against. It was the high time when any one was dared to pay to get Dozer, Excavator, loader… Name it!, for nothing would be considered more important than getting equipment at any price to start, progress or complete his commitment, unfairly shoot up the price in almost  50%.  

Scientifically to fix the rental rate of a machine should consider costs of Delivery Price, Estimated Ownership Period, Lube Oils, Filters, Grease, Tires, Undercarriage, Repair Reserve, Special Wear Items, Operator’s Hourly Wage, Interests Rate (IRR or MARR), Insurance Rate, Property Tax, Tire Replacement Cost if desired, Residual Value at Replacement, in general OWNING COSTS and OPERATING COSTS.

But in Ethiopia Construction business is the victim of scarcity or consent of unprofessional brokers due to unreasonable price changes (as such it would be better to say it “price rise” than “price change”), derived from self benefit. 

Consequently, as professionals in the construction industry, we have made our analysis with numbers and assumptions, to come up with reasonable rate for two of the main equipments, Dozer & Loader.

Dozer (D8R) == 768.03

Loader (950H) ==    541.87

Finally; we expected the cost “drop” will not end here but it is the concern and expectation of the “Construction Proxy” team for additional adjustment until the reasonable price rules in the coming six months, which is a reduction of  up to about 30%.

Light rail civil works could be completed this year

China Railway Engineering Corporation (CREC), the company constructing the first light rail transit in Ethiopia, is hoping to finalize civil works and commence electromechanical works this year.

Construction of the 34 km Addis Ababa Light Rail Transit project (AA-LRT) began in January 2012. EREC agreed to complete the project within three years in a contract it signed with Ethiopian Railways Corporation (ERC) in September 2009.Initially, delivering the project within the agreed time table seemed to be a  daunting task for the project owners given difficulties faced to ensure right of ways particularly due to public utility lines and buildings.

“There is more cooperation and commitment from all stakeholders now and we are getting the support we need,” Behailu Sentayehu, project manager, told WIC.He said with the current momentum, they expect to finish civil works this year in all areas where right of way is secured. “We are keeping an eye on outstanding issues of right of way in some areas and we hope to secure them to achieve our target,” Behailu said.That means the contractor could move to the next project stage of electric and electromechanical works, including track laying and power sub stations for the electric powered rail transit. The corporation will also purchase signaling and communication equipments as well as tramcars from China this year, according to the project manager.  ERC had announced that it has, so far, accomplished 43 percent of the overall project. The 475 million USD project went in full-swing after the nation secured 85 percent of the budget from EXIM Bank of China. The remaining 15 percent is covered by the government.   The double track rail extends 17.35 km from east to west direction stretching from Ayat Village to Tor Hailoch passing through Megenagna, Legehar and Mexico. The north to south line has a length of 16.9 km rail track start from a terminal at Menelik Square and passes through Merkato, Lideta, Legehar, Meskel Square, Gotera and Kaliti. The two directions will have a common track of about 2.8Km.Once the project is completed, ERC hopes to commence Phase two of the project, which will extend the track in all four directions to the outskirts of the city.

MoUDC Targeted to Create 1.8 Million Jobs

The Ethiopian Ministry of Urban Development and Construction announced that its has targeted to create 1.8 million jobs in the current fiscal year.

Speaking in a meeting organized to evaluate the last year performance of the state owned Construction Design S.C, the State Minister Engineer Haile Meskel Tefera said, one million of the total job is expected to be created in the construction sector. Ongoing and new road and housing projects are helping to realize this goal, he said.

 The Minister said construction of 50,000 condominium houses which will be launched in this budget year is among such projects.

Construction Design S.C is a state owned consulting firm that deals mainly with the design, construction and supervision of roads, bridges and airports.
