👉Here’s a detailed breakdown of the two truss designs shown:

🔹 Truss A
- Slope: 12/12 (steep pitch, symmetrical rise and run) 
- Span (L): Between 5 m and 8.5 m 
- Divisions: 
  - Top chord divided into L/4 + L/4 
  - Bottom chord divided into L/3 + L/3 
- Angles: 60°, 30°, 30° 
- Special Note: Internal angles include 20° and 30°, giving a more distributed load path. 
- Structural Behavior: This layout balances forces with smaller internal angles, making it efficient for moderate spans.

🔹 Truss B
- Slope: 12/12 (same as Truss A) 
- Span (L): Between 5 m and 8.5 m 
- Divisions: 
  - Top chord divided into L/4 + L/4 
  - Bottom chord divided into L/3 + L/3 
- Angles: 60°, 30°, 30° 
- Special Note: Internal angles include 20° and 90°, creating a vertical member. 
- Structural Behavior: The vertical angle (90°) provides stronger vertical support, useful for central load transfer, but may increase material usage compared to Truss A.

⚖️ Comparison
- Both trusses share the same slope and span range. 
- Truss A distributes forces diagonally with smaller angles → lighter, efficient design. 
- Truss B introduces a vertical member → stronger central support, but heavier. 
- Choice depends on load type: 
  - Truss A: Better for uniform roof loads. 
  - Truss B: Better for concentrated loads at mid-span.

👉Batter Boards in Foundation Layout 👇

👉Batter Boards in Foundation Layout

🏷Purpose
Batter boards are temporary wooden frameworks used to outline the foundation of a building before excavation or concrete work begins. They help ensure accuracy in dimensions, alignment, and right angles.

Components
- Batter Boards: Wooden planks fixed on stakes driven into the ground.
- String Lines: Tightly stretched strings attached to batter boards to mark foundation edges.
- Diagonal Check: Ensures squareness by measuring diagonals for equal length.
- 90° Right Angle: Critical for maintaining proper geometry of the foundation.

Process
1. Set Up Batter Boards: Place them around the perimeter of the planned foundation.
2. Attach String Lines: Stretch strings across batter boards to define the foundation width and length.
3. Check Right Angles: Use diagonal measurements to confirm accuracy.
4. Mark Foundation Boundaries: The intersection of string lines indicates exact excavation lines.

Importance
- Guarantees precision in foundation layout.
- Prevents errors in excavation and concrete placement.
- Provides a clear visual guide for workers on site.

👉Construction Of ህድሞ

@etconp 👇

🚧The ህድሞ is a rectangular prismatic dwelling structure that is dominant in Eritrea.

Unlike the standard huts found in most of Africa, the ህድሞ is designed and constructed in such a way that it is compartmentalized to provide dining, socializing, sleeping, and cooking, areas not different than the modern villa.

To start with, there is the ውሻጠ (kitchen) where the ጣይታ፡ ሃንዛ(ምልሶ)፡ ቅጫ፡ ጎጎ፡ ገዓት፡ ሽልጆ፡ ሕልበት: ቆሎ-ጥጥቖ and a variety of finger-licking ኣጻብሕ፡ are cooked. They are kept in the natural coolness obtained from the ህድሞ walls made from stone and mud and the ናሕሲ (roof) made of various sized wood (timber), tree branches, hay, and dirt, supported by ኣዕኑድ (Pillars). Add to that, there is about 10 cm (4 inches) open spacing between the roof and top part of the walls at the ምድሪ ቤት (main floor) area for circulation of fresh air where the livestock could sleep in. Sometimes they are kept outside the ህድሞ in the ገበላ (front yard) secured by ደንደላ (gate).

A section of the ገበላ is the front part of the ህድሞ where the ናሕሲ protrudes to provide shelter from the elements, mainly rain and sun.

Usually, there are 2 ንእድታት (beds) for those who love to sleep in the open or to guard the livestock against any possible wild animal intrusion even if there is a guard dog.

If one is lucky, there is a pile of ድዂዒ (manure) and ዒባ/ዓኾር (dung) or ashes from the እቶን useful for fertilizing the grain fields and to augment a firewood that the villagers need.

The ውሻጠ is made up of the main one where many of the cooking is done - እቶን ሞጎጎ፡ ሞቕሎ & ጻሕሊ፡ - and another one where the ስዋ፡(beer) ብርዚ፡(sweetened beer)or ሜስ፡ (special alcoholic drink sweetened by honey), and other essentials are kept like ጠስሚ፡ ልኻይ፡ ብራሕ፡ ኣጅቦ: ጸባ፡ ሽሮ፡ በርበረ፡ መዓር፡ ጌሶ፡ ቀመማት፡ ጥረምረ at a cool temperature. Of course, there may be a specially built-in "hole" strategically located on the floor on one section of the ውሻጠ for our women's grooming needs the ጉብጥሽ።

The largest part of the ህድሞ is the ምድሪ ቤት፡ (main floor) where it is divided from the ውሻጠ by some well built and neatly lined up ቆፎታት (grain silos) and a መሕለፊት (passage)። The ምድሪ ቤት hosts the ንእድታት ምስ ማእስታቱ፡ (beds) መደባት ምስ ኣጎዛታቱ፡ (seating benches) መንበራት (chairs) and the መጥሓን with its ጓል መዲድ(grain grinding utensil) and ቦኽራ (flour storage facility).

Finally, there is that ሑጋ (back door/ back yard), which many times includes a መረባዕ (corrugated zinc roofed stone-walled rooms).

Nowadays, the all-purpose iconic ህድሞ is being built by sustainable materials (like cement and mortar) for the ኣዕኑድ (pillars) and ኣግማል (beams).

Many are also being electrified via Solar energy. Some of them are receiving water plumbing with a Satellite Dish and mobile phone service.

I have seen some ሃዳሙ with solar power for lighting and thermal water heaters, as well as rain gutters drainage system to catch critical water supply into an underground cistern; and a middle eastern type toilet (not my favorite) with an underground septic tank that holds the waste for disposal.

So, ladies and gentlemen, with a ህድሞ at your disposal who needs a villa? 😀

" የሪል ስቴት አልሚዎች ገንብተው የማያስረክቡትን ቤት ከገበያ ዋጋ በታች በመሸጥ ላይ ይገኛሉ " - ማኅበሩ

በኢትዮጵያ የሪል ስቴት ኢንዱስትሪው የሕዝብ አመኔታ በማጣቱ ምክንያት እየተቀዛቀዘና እየሞተ እንደሚገኝ የኢትዮጵያ ሪል ስቴት አልሚዎች ማኅበር አስታወቀ።

የማኅበሩ የቦርድ ሰብሳቢ አቶ ዓለማየሁ ከተማ ፥ " የሪል ስቴት ኢንዱስትሪው የሕዝብ አመኔታን በማጣቱ እንዳያድግና ወደፊት እንዳይራመድ እየሆነ ይገኛል " ማለታቸውን ሪፖርተር ጋዜጣ ዘግቧል።

የሪል ስቴት አልሚዎች ለቤት ፈላጊዎች በውላቸው መሠረት ቤቶቻቸውን ገንብተው ባለማስረከባቸውና ቃላቸውን ባለመጠበቃቸው ዘርፉን በሕዝብ ዘንድ አመኔታ እንዳይኖረው አድርጎታል።

አቶ ዓለማየሁ፣ " የሪል ስቴት አልሚዎች ገንብተው የማያስረክቡትን ቤት ከገበያ ዋጋ በታች በመሸጥ ላይ ይገኛሉ። ይህ ደግሞ በርካታ ገንዘብ ከሕዝብ በመሰብሰብ ለክስና ውዝግብ መነሻ እየሆነ ይገኛል " ብለዋል።

አክለውም አልሚው ለቤት ፈላጊው ማኅበረሰብ ታማኝ ሆኖ ቤት ማስረከብ ባለመቻሉ ዘርፉ እየተቀዛቀዘና እየሞተ ይገኛል ሲሉ አስታውቀዋል።

" ታማኝ ሆኖ በገባው ውሉ መሠረት ቤት ገንብቶ የማያስረክብ ሪል ስቴት አልሚ እና ወረቱን የሚበላ ነገዴ አንድ ናቸው "  ያሉ ሲሆን ማኅበራቸው በቤት አልሚዎችና ገዥዎች መካከል መተማመን እንዲኖር የሚያስችሉ ሥራዎች እየሠራ እንደሚገኝ አመልክተዋል።

ማኅበሩ ከተመሠረተ የአንድ ዓመት ጊዜ ቢኖረውም ከዋጋ በታች በውሸት ማስታወቂያ ገዥው እንዳይጭበረበርና ዘርፉ በሕግ እንዲመራ የማድረግ ሥራ እየሠራ እንደሚገኝ ጠቁመዋል።

" በኢትዮጵያ የሚገኝ ማንኛውም ሪል ስቴት አልሚ ፈቃድ አግኝቶ በሕጋዊ መንገድ እንዲንቀሳቀስ አሠራር ተዘርግቷል፤ ችግር ተፈጥሮ ከተገኘም ፈቃዱ የሚነጠቅበትና የሚጠየቅበት ሥርዓትም ተበጅቷል " ብለዋል።

🔹 Advanced Wood Truss Structural Design

Design A

- Optimized for medium spans between 5 m and 8.5 m.
- Roof pitch is shallow, with inclination of 4–5/12.
- Posts are spaced at 60 mm, with bracing at 30 mm.
- Diagonal brace is twice the web thickness (2D), ensuring stability.
- Best suited for residential or light commercial structures where moderate span and shallow roof pitch are required.

Design B

- Designed for the same span range (5 m to 8.5 m).
- Roof pitch is higher at 3/12, offering better drainage and aesthetic variation.
- Stronger bracing connections at 90 mm, with central support at 40 mm.
- Diagonal brace (2D) adds stiffness and reduces deflection.
- Ideal for structures needing greater load resistance and higher roof pitch, such as warehouses or buildings in heavy rainfall regions.
