👉በሊዝ የተያዘ መሬት ላይ ግንባታ መጀመሪያና ማጠናቀቂያ የጊዜ ገደብ

✂️ሀ) ግንባታ ማስጀመሪያ

አንድ ግለሰብ/ድርጅጥ በከተማ ቦታ ላይ በሊዝ የተረከበው ቦታ ላይ የሊዝ ውል ከፈረመበት ቀን ጀምሮ ለቦታው በተቀመጠው ደረጃ መረሰት ግንባታ እንዳለበት የሚደነግግ የጊዜ ጣሪያ ተቀምጧል።

በሊዝ ቦታ ላይ የግንባታ መጀመሪያ የጊዜ ጣሪያ፦ ለአንሰተኛ ደረጃ ግንባታዎች = 6 ወር፣ ለመካከለኛ ደረጃ ግንባታዎች = 9 ወር፣ እና ለከፍተኛ ደረጃ ግንባታዎች = 18 ወር ነው።

ሆኖም ግን እስንደአካባቢው ነባራዊ ሁኔታ ወይም በተለያዩ ምክንያቶች በተጠቀሱት የጊዜ ገደቦች ግንባታ ሳይጀመር ቢቀር ለአንድ ዙር ብቻ የሚፈቀድ ለአንሰተኛ ደረጃ ግንባታዎች  6 ወር፣ ለመካከለኛ ደረጃ ግንባታዎች 9 ወር፣ ለከፍተኛ ደረጃ ግንባታዎች አንድ ዓመት ተጨማሪ የግንባታ ማስጀመሪያ ጊዜ በግንባታ ፍቃድ ሰጪው አካል ከማስጠንቀቂያ ደብዳቤ ጋር ሊሰጣቸው ይችላል።

✂️ለ) ግንባታ ማጠናቀቂያ

በሊዝ ቦታ ላይ ግንባታ የማጠናቀቂያ የጊዜ ገደብ፦ ለአንሰተኛ ደረጃ ግንባታዎች 24 ወራት፣ ለመካከለኛ ደረጃ ግንባታዎች 36 ወራት፣ እና ለከፍተኛ ደረጃ ግንባታዎች  48 ወራት ነው።

ነገር ግን የአካባቢው የግንባታ ፍቃድ ሰጪ አካል ካመነበት የግንባታውን ውስብስብነት እያየ ሊያራዝምለት ይችላል።

ሆኖም ግን ለግንባታ ማጠናቀቂያ የሚሰጠው ጊዜ በማንኛውም ምክንያት (ሁኔታ) ቢሆን ለአንሰተኛ ደረጃ ግንባታዎች  2 ዓመት 6 ወር፣ ለመካከለኛ ደረጃ ግንባታዎች 4 ዓምት፣ እና ለከፍተኛ ደረጃ ግንባታዎች ከአምስት ዓመት መብለጥ የለበትም።

👉ፉካ (Grooving) ምንድነው?

💫In building construction, grooving serves several important purposes, primarily related to concrete slabs, pavements, and masonry walls.

📜Here are the key purposes of grooving:

🚧1. Control of Cracking (Contraction Joints)

- Grooves are cut into concrete slabs to create controlled joints that help prevent random cracking caused by shrinkage, temperature changes, or settling.
- By providing a weakened plane, cracks are directed along the groove rather than appearing randomly.

🚧2. Enhancing Skid Resistance

- In pavements, roads, and industrial floors, grooving improves traction by creating a textured surface.
- This is especially important in airport runways, highways, and parking garages to prevent skidding in wet conditions.

🚧3. Expansion Joints

- Grooves allow for thermal expansion and contraction of concrete, reducing stress buildup that could lead to cracks or buckling.

🚧4. Aesthetic and Architectural Design

- Grooves can be used decoratively in concrete walls, floors, and facades to create patterns or textures.
- They help in segmenting large surfaces for visual appeal.

🚧5. Drainage Improvement

- In pavements and outdoor slabs, grooves can channel water away, reducing ponding and improving safety.

🚧6. Structural Stress Relief

- In masonry and brickwork, grooves (such as control joints) help manage movement due to thermal changes or settling.

⭐️Common Applications:

- Concrete floors & pavements (control joints)
- Roads & runways (skid resistance)
- Brick & masonry walls (expansion control)
- Decorative concrete finishes

🔰Methods of Grooving:

- Saw-cutting (post-placement)
- Tooled joints (during concrete finishing)
- Formed grooves (using inserts before pouring)

❇️Grooving is a preventive and functional technique that enhances durability, safety, and aesthetics in construction.
