ለሕዳሴ ግድብ ባለፉት 10 ወራት 1 ነጥብ 2 ቢሊዮን ብር መሰብሰቡ ተገለጸ

ለታላቁ የኢትዮጵያ ህዳሴ ግድብ ባለፉት አስር ወራት 1 ነጥብ 2 ቢሊዮን ብር መሰብሰቡን የታላቁ ሕዳሴ ግድብ ማስተባበሪያ ፕሮጀክት ጽሕፈት ቤት ለአዲስ ማለዳ ገልጿል።

በዚህም ከሃምሌ 01/2014 እስከ መጋቢት 30/2015 ድረስ ከአገር ዉስጥ ቦንድና ስጦታ 897 ሚሊዮን በላይ መሰብሰብ መቻሉ የተገለጸ ሲሆን፤ ከዲያስፖራ ቦንድና ስጦታ ከ13 ሚሊዮን በላይ እንዲሁም ከአጭር የሞባይል መልእክት አገልግሎት ከ110 ሚሊዮን ብር በላይ እና በኢትዮጵያ ኤሌትሪክ ኃይል የስጦታ አካውንት ከ100 ሚሊዮን ብር በላይ እንደተሰበሰብ ተጠቁሟል።

በሚያዚያ ወር እንዲሁ ከአገር ውስጥ ቦንድና ስጦታ፣ ከአጭር የሞባይል መልእክት አገልግሎት እንዲሁም ከኢትዮጵያ ኤሌትሪክ ኃይል የስጦታ አካውንት በአጠቃላይ ከ67 ነጥብ 6 ሚሊዮን ብር በላይ ገቢ መሰብሰቡም ነው የተመላከተው።

ሆኖም በዘንድሮው በጀት ዓመት ባሉት አስር ወራት ለህዳሴ ግድቡ የተሰበሰበው ጠቅላላ ገንዘብ ከባለፈው በጀት ዓመት ተመሳሳይ ወቅት ጋር ሲነጻጸር በተወሰነ መጠን መቀነሱን የታላቁ ሕዳሴ ግድብ ማስተባበሪያ ፕሮጀክት ጽሕፈት ቤት የሚዲያ ኮሚዩኒኬሽን ዳይሬክተር ሀይሉ አብርሃም ለአዲስ ማለዳ ገልጸዋል።

ፓሪስ ከተማ ከ37 ሜትር በላይ ከፍታ ያላቸው ህንጻዎች እንዳይገነቡ ከለከለች

የከተማዋ ነዋሪዎች በአዲሱ ህግ ምክንያት ለሁለት ተከፍለዋል ተብሏል
ፓሪስ ከተማ ከ37 ሜትር በላይ ከፍታ ያላቸው ህንጻዎች እንዳይገነቡ ከለከለች፡፡

በዓለማችን ካሉ ውብ እና ተወዳጅ ከተሞች መካከል አንዷ የሆነችው ፓሪስ ውበቷን ይዛ ለመቀጠል በሚል የህንጻዎችን ርዝመት ገድባለች፡፡

ከተማዋ ከፈረንጆቹ 1977 ጀመሮ ከ37 ሜትር በላይ ርዝመት ያላቸው ህንጻዎች እንዳይገነቡ ህግ አውጥታ የነበረ ቢሆንም የህን ህግ በ2010 ሰርዛ ነበር፡፡

የቀድሞ የፓሪስ ከንቲባ በርትራንድ ዴላኖ በ2010 የቀደሞውን ህግ በመሻር በከተማዋ እስከ 180 ሜትር ርዝመት ያላቸው ህንጻዎች እንዲገነቡ ሌላ ህግ ማውጣታቸውን ዩሮ ኒውስ ዘግቧል፡፡

ይህ አዲስ ህግ መውጣቱን ተከትሎ በፓሪስ አልፎ አልፎ ብቻቸውን ወደ ሰማይ የወጡ ህንጻዎች መገንባታቸው የከተማዋን ውበት አጥፍቶታል በሚል ትችቶች ሲቀርቡ ቆይተዋል ተብሏል፡፡

ይህን ተከትሎም ፓሪስ ከ50 ዓመት በፊት አውጥታው ወደ ነበረው ህግ መመለሷን የገለጸች ሲሆን በከተማዋ ከ 37 ሜትር በላይ ርዝመት ያላቸው ህንጻዎች እንዳይገነቡ በድጋሚ ከልክላለች፡፡

ጉዳዩ የፓሪስ ከተማ ነዋሪዎችን ለሁለት ከፍሎ እያከራከረ ሲሆን የተወሰኑት ህጉ ለከተማዋ ውበት ጥሩ ሲሉ ገሚሶቹ ደግሞ ፓሪስ በዚህ ህግ ምክንያት ከእኮዮቿ ለንደን እና ኒዮርክ ጋር ስትነጻጸር ተመራጭነቷን ይቀንሳል በማለት ላይ ናቸው ተብሏል፡፡

ፓሪስ ወደ ቀድሞ ህጓ መመለሷ ለአየር ንብረት ለውጥ የሰጠችው ትኩረትን ያሳያል የተባለም ሲሆን የአዳዲስ ህንጻዎች ግንባታ የአየር ብክለትን ይጨምራሉ ሲሉም እየተከራከሩበትም ነው፡፡

ለንደን ቅጥ ባጡ ረጃጅም ህንጻዎች ውበቷን እያጣች ነው በሚል ፈረንሳዊያን የዋና ከተማቸውን ውሳኔ ሲደግፉ ሌሎቹ ደግሞ በዚህ ህግ ምክንያት ፓሪስ ውዳቂ እና ያልለማች ከተማ ያስብላታም ብለዋል፡፡

🚧Dynamic compaction

✨Dynamic compaction involves the controlled impact of a crane hoisted weight, of around 10-12 tonnes, falling in a pre-determined grid pattern to improve loose, granular and mixed soils and fills.

🌟Common uses

✨Increase bearing capacity Decrease settlement Mitigate liquefaction Avoid major below-ground obstruction removal
Process

✨Dynamic compaction is a ground improvement technique that densifies soils and fill materials by using a drop weight.

🌟Advantages

➪ Capable of compacting a wide variety of weak soils

➪ Increased bearing capacity

➪ Reduced settlement

➪ Sustainable technique using limited material import

➪ Can improve soil conditions on marginal sites to the extent that shallow foundations can be used without deep excavation or piling

➪ Removal of compressible, contaminated fills can sometimes be avoided

👉COMMON CONCRETE PROBLEMS AND THEIR
PREVENTION

⏩There are many problems we might be facing during and after concreting.

⏺To produce high quality concrete we must take some precautions to avoid those common problems during concreting.

⏺In this article, we will discuss on common concrete problems and how to prevent them.

A) BLEEDING

⏺Bleeding refers to as a tendency of water to appear on the top surface of concrete after finishing. Due to bleeding some measure of water (with sand particles and other cementing materials) appears at the surface of the concrete.

▶️Following precautions should be taken to reduce bleeding in concrete.

1. Design the mix appropriately.
2. Include least water content in the mix.
3. Use greater amount of cement content.
4. Use greater amount of fine particles.
5. Utilize a little measure of air entraining
admixture

⏺B) SEGREGATION

▶️Segregation means separation of coarse aggregates from the concrete surface due to poor compaction.

▶️It is generally seen in the plastic stage of concrete.

▶️As a result honeycomb, laitance, scaling, porous
layer, bond failure etc.

⏺can be formed in concrete.

▶️Following precautions should be adopted to prevent segregation in concrete.

1. Design the mix appropriately.
2. Never use excessive water content.
3. Take care of handling, placing, and proper
compaction of concrete.
4. Do not allow the concrete to be dropped from more heights.
5. Use air entraining admixture.
6. Keep the formwork to be watertight.

⏺C) LAITANCE

▶️The appearance of cement sand particles on the
surface of freshly placed concrete is known as
laitance.

▶️It is mainly occurred due to the bad effect of bleeding and segregation of concrete.

▶️The bond between subsequent layers of concrete becomes weaker and as a result, laitance is developed.
Following precautions can be taken to stop the occurrence of laitance in concrete.

1. Clay, dust, silt content etc should be removed
before mixing the concrete.
2. Water-cement ratio should be maintained
properly.
3. Water should not be sprayed on the concrete
surface during finishing work.
4. Use well graded fine aggregates in the mix.
5. Add little amount of water reducing admixture in the concrete mix.

⏺D) SCALING

▶️Scaling is the physical deterioration of concrete in
which the surface layer of concrete broke down,
pitted or flaked away. Due to this effect concrete
surface becomes worse. Scaling can be prevented
by taking same precautions adopted for laitance.

⏺E) PLASTIC SHRINKAGE CRACKS:

▶️When the evaporation rate of water mixed in the concrete is greater than the bleed water of concrete, plastic shrinkage cracks are developed on the surface of the concrete. Basically, this type of cracks occurs in very hot climate.

⏺F) DUSTING:

▶️Dusting can be prevented by taking following precautions.
1. Maintain a suitable water/cement ratio in the
concrete.
2. Utilize dust free aggregates in the mix.
3. Guarantee appropriate hydration of concrete.
4. Avoid early surface finishing of concrete.

Here are most popular project management methodologies and their applications:
1. Waterfall: follows a linear, sequential approach where each phase is completed before progressing to the next. It is not commonly used in construction due to its inflexibility in accommodating changes during the project.

2. Agile: Agile emphasizes flexibility, collaboration, and iterative improvements. Agile can be applied to construction by breaking the project into smaller tasks and frequently reassessing progress. Examples include Scrum and Kanban.

3. Critical Path Method (CPM): CPM is widely used in construction, as it identifies the most crucial tasks and helps in optimizing the project schedule. It allows for efficient resource allocation and improved project monitoring.

4. Program Evaluation and Review Technique (PERT): PERT is a statistical method used to estimate project completion time based on the analysis of task duration and dependencies. It is well-suited for construction projects with uncertain activity durations.

5. Lean Construction: Inspired by lean manufacturing principles, LC focuses on minimizing waste and enhancing value through continuous process improvement. This methodology optimizes project performance and resource efficiency.

6. Project Management Body of Knowledge (PMBOK): PMBOK is a set of standardized best practices and processes applicable to various industries, including construction. It covers areas like risk management, quality control, and cost estimation.

7. Integrated Project Delivery (IPD): IPD is a collaborative approach specifically designed for the construction industry. It involves all project stakeholders (owners, designers, contractors) working together from project inception to completion, which fosters teamwork, communication, and shared responsibility for project success.
