Engineering phase in project is very important. Anything can predict & calculated in this phase. If there are some thing wrong in the sketch design, it can be found during calculation. Usually calculation phase or engineering phase make every engineer headache, its need more power, stamina, concentration and patient.
If engineer can not focus and take an easy way to design something (structure, pipe line system, mechanical integrated equipment & etc) it can be a dangerous thing!.
I found it in my last project. Our civil engineer very improper/careless about engineering phase. When they fill valley with soil, they do not calculate accurate, so when it reach erection phase, they are no procedure that must be obey by subcontractor to full fill those valley with soil.
Time after time when rainy season come, suddenly it happened!, the soil slide down! with almost structure that finish constructed. Oh my God, this is un forgetable!
More time to finish this project! more budget again, more time….😦
This a Nightmare!😦
