በፌዴራል የመንግሥት ግዥና ንብረት አስተዳደር ኤጀንሲ የጨረታ ሰነድ (SBD-Works) መሠረት፣ የሪቴንሽን (Retention) ገንዘብ ማለት ኮንትራክተሩ የገባውን ውል በትክክል መፈጸሙን ለማረጋገጥ እና የመጨረሻ ሂሳብ ከመወራረዱ በፊት ለሚታዩ ጉድለቶች እንደ ዋስትና እንዲያገለግል አሰሪው (Employer) ከእያንዳንዱ ክፍያ ላይ ቀንሶ የሚያስቀረው የገንዘብ መጠን ነው።
የቅናሽ አሰራር (GCC Clause 61)
በGCC አንቀጽ 64.1 (ሐ)መሠረት፣ በኮንትራክተሩ የሚቀርቡ የእያንዳንዱ ጊዜያዊ የክፍያ ሰርተፊኬቶች (Interim Payment Certificates) በGCC አንቀጽ 61 በተጠቀሰው መሠረት የሪቴንሽን ቅናሽ ይደረግባቸዋል። ይህ አሰራር አሰሪው በሥራው ሂደት ውስጥ የፋይናንስ ዋስትና እንዲኖረው ያስችለዋል።
የተቀናሽ መጠን ገደብ (based on SCC)
በውሉ ልዩ ሁኔታዎች (SCC) ላይ የሚቀነሰው መቶኛ የሚወሰን ቢሆንም፣ አብዛኛውን ጊዜ ከእያንዳንዱ ጊዜያዊ ክፍያ (IP) ላይ 5% የመቀነስ አሰራር የተለመደ ሲሆን፣ በ GCC አንቀጽ 61 መሠረት ግን የሚጠራቀመው ጠቅላላ የሪቴንሽን መጠን በማንኛውም ሁኔታ ከጠቅላላ የውል ዋጋው 10% መብለጥ እንደሌለበት በጥብቅ ተደንግጓል።
የሪቴንሽን (Retention) ገንዘብ መች ይለቀቃል??
1⃣First release፦ጊዜያዊ ርክክብ (Provisional Acceptance) ተፈጽሞ የምስክር ወረቀት ሲሰጥ፣ የተጠራቀመው የሪቴንሽን ገንዘብ 50 በመቶው (ግማሹ) ለኮንትራክተሩ ይለቀቃል።
2⃣Final Release፦በGCC አንቀጽ 89 መሠረት የመጨረሻ ርክክብ (Final Acceptance) ተፈጽሞ የምስክር ወረቀት ሲሰጥ እና የኮንትራክተሩ ግዴታዎች በሙሉ ሲጠናቀቁ ቀሪው 50 በመቶ ይለቀቃል።
በባንክ ዋስትና (Bank Guarantee) መተካት በውል ልዩ ሁኔታዎች (SCC) ላይ ከተፈቀደ፣ አሰሪው ኮንትራክተሩ ሁለተኛውን 50 በመቶ የሪቴንሽን ገንዘብ ያለምንም ቅድመ ሁኔታ በሚቀርብ የባንክ ዋስትና (Unconditional Bank Guarantee) እንዲተካ ሊፈቅድ ይችላል። ይህም ኮንትራክተሩ የተያዘበትን ገንዘብ አስቀድሞ በማውጣት ለሥራ ማስኬጃ እንዲጠቀም ይረዳዋል።

👉Main Types of Dams – Explained
1. Gravity Dam
- Built of solid concrete or masonry.
- Relies on its own weight to resist water pressure.
- Common in wide valleys with strong bedrock foundations.
2. Arch Dam
- Curved design that transfers water pressure into canyon walls.
- Requires strong rock abutments for stability.
- Efficient use of materials compared to gravity dams.
3. Buttress Dam
- Thin concrete face supported by triangular buttresses.
- Economical in material use but complex in design.
- Suitable for wide valleys with firm foundations.
4. Embankment Dam
- Made of compacted earth or rockfill with a waterproof core.
- Flexible and adaptable to different valley shapes.
- Most common type worldwide due to cost-effectiveness.
📌 Key Takeaway
Each dam type is chosen based on geology, valley shape, material availability, and cost considerations. Gravity and arch dams rely on concrete strength, while buttress and embankment dams optimize material use and adaptability.
