Guji badhanka ku yaal Midig
1. Aasaaska Derbiga Saldhigga Hoose:Aasaas qoto dheer oo loogu talagalay dhismayaasha dhaadheer, warshadaha, bakhaarada, dhismayaasha ganacsiga iyo kuwa la deggan yahay. Aasaas tuulmo ah (ku habboon dhammaan noocyada dhismaha).
2. Aasaaska Buundada Tuulada:Aasaaska culayska qaada ee buundooyinka waaweyn, buundooyinka tareenka, iyo buundooyinka magaalooyinka. Aasaaska u tuul buundooyinka webiga, harada, iyo badda ka gudba.
3. Dhismaha Dekadda:Saldhigyada xamuulka qaada ee loogu talagalay terminaalka dekedaha, goobaha maraakiibta, iyo goobaha dekedda. Qalab culus iyo xarumaha maaraynta xamuulka dekedaha.
4. Mashruucyada Tamarta Dabaysha iyo Injineeriyadda Badda ee Xeebaha:Aasaaska marawaxadaha dabaysha ee xeebaha. Naqshadeynta taageerada goobaha xeebaha, dhuumaha badda, derbiyada badda, iwm. Caabinta hirarka, iska caabbinta hirarka, iyo iska caabbinta daxalka badda.
5. Injineeriyadda Madaniga ah ee Cabbirka Weyn:Aasaas qoto dheer oo leh tuulmooyin dhexroor weyn leh oo loogu talagalay mashaariicda injineernimada madaniga ah ee baaxadda weyn (sida biyo-xireennada, saldhigyada dhulka hoostiisa mara, iyo godadka). Taageerada mashiinnada warshadaha iyo culaysyada dhismaha.
1) Xafiiska Laanta - Taageerada ku hadasha luqadda Isbaanishka, kaalmada nadiifinta kastamka, iwm.

3) Waxaa baaraya hay'ado awood leh sida CCIC, SGS, BV, iyo TUV, iyadoo la adeegsanayo baakado caadi ah oo badda ku habboon.
1 Baakad:Xarig bir ah si fudud loogu maareeyo. Baloogyada alwaaxa ama dunnage-ka ayaa la dhigaa inta u dhaxaysa meelaha la isku xidho si looga fogaado isbeddelka xubnaha inta lagu jiro gaadiidka. Daawaynta dusha sare (ikhtiyaar): Rinji madow, saliid ka hortagta miridhku, filim balaastig ah. Tuubooyinka galvanized ee kulul lagu dahaadhay waxaa lagu dahaadhi karaa filim ilaalin ku meel gaar ah si looga fogaado xoqidda dusha sare. Baakad gaar ah ayaa la bixin karaa.
2 Gaarsiinta:Dhererka kaydka caadiga ah: 6m, 12m. Waxaa laga heli karaa dherer gaar ah. La soco Tareenka Badda iyo Wadada Khuseysa Ku habboon gaadiidka badda, tareenka ama waddooyinka. Waqtiga keenista badanaa waa 15-30 maalmood marka la helo lacagta, iyadoo ku xiran tirada iyo qeexitaanka. Ku habboon dhoofinta adduunka oo dhan, oo leh dukumeenti dhammaystiran (shahaadada kormeerka, liiska baakadaha, biilka rarista).
3 Taxaddar oo ku saabsan maaraynta:Ha isticmaalin suuf ama jillaab aan lahayn suuf si aad si toos ah ugu falgasho dusha sare ee tuubada si looga fogaado in tuubooyinku ay qalloocaan. Ku hay meel qabow, qalalan oo hawo fiican leh, iska ilaali miridhku ka hor inta aan la rakibin. Xamuulka iyo culeyska badan fadlan u hoggaansan xeerarka rarista deegaanka.
