🔹 4. Uburyo bwo gukora Setting Out (Step by Step)

🪜 Step 1: Guhitamo Base Line

Tangirira ku murongo w’ingenzi (base line) ushingiye ku bipimo bya plan.

Uwo murongo uba ari wo musingi w’ibindi byose bizakurikiraho.

🪜 Step 2: Kumenya Aho Imfuruka Ziri (Right Angles)

Koresha 3–4–5 Triangle Method:

Pima 3m ku murongo wa mbere,

4m ku murongo wa kabiri,

maze aho bihurira hagomba kuba 5m kugira ngo hamenyekane ko ari 90°.

🪜 Step 3: Gushyiraho Pegs n’Imirongo

Shyiraho pegs ku butaka, uzihuze n’imigozi (strings) yerekana aho foundation izacukurwa.

Iyo mirongo igomba kugera ku gipimo nyacyo nk’uko biri kuri plan.

🪜 Step 4: Kugenzura Accuracy

Reba niba intera hagati y’imfuruka, ubugari n’uburebure bihura neza n’ibyo ku drawing.

Koresha tape na spirit level kugira ngo wemeze ko byose biri ku murongo nyawo.

🪜 Step 5: Kubika Imipimo neza

Nyuma yo kurangiza, shyira profiles cyangwa batter boards kugira ngo imirongo itazimanganywa mbere yo gucukura foundation.

🔹 5. Ibyo ukwiye kwitondera

Kugenzura buri murongo inshuro nyinshi mbere yo gucukura.

Kugendera ku bipimo bya plan, ntuhindure ibipimo ku bushake.

Kurinda ibimenyetso (pegs na lines) kugira ngo bitimangane.

Kwitondera precision — ikosa rito rishobora gutuma inzu yose yubakwa nabi.

🔹 6. Ibyo Setting Out igufasha

Kubaka inzu ifite intera n’umurongo nyabyo.

💡 Icyitonderwa cy’Abiga

Buri gihe ujye utangira setting out ufite drawing yemejwe (approved drawing).

Ibyo wipimye byose ujye ubirandika ku rupapuro cyangwa muri notebook.

Niba ari kuri site, ujye ukurikirana na site engineer kugira ngo ibyo ukora byemezwe.

🎯 Umwanzuro: Setting Out ni intambwe y’ibanze kandi ikomeye mu bwubatsi. Iyo ikozwe neza, irinda amakosa yose yo kubaka nabi, igatuma inzu ijya ku gipimo neza nk’uko byateganyijwe kuri plan
