building a roof with metal frame and roof insulated type "attic" constructive advice

[angiolino]

hello, I know I should appeal to a technical, engineer, architect, surveyor or structural engineer or higher, but I should make a cost estimate what you think?

ho anche fatto i conti della massaio, in linea di massima se manca qualche cosa ti invito a sottolinearmelo
Elenco materiali:
1) N°6 pilastri esterni h= 2,80+ 3 pilastri interni 3,80 hea 120
6x2,80= 16,8 m 
3,80x3 =11,4 m
Totale 11,4+16,8 = 28,2 metri x 19,9= 561kg peso
Capriata:
14,02x n° 4 = 56 metri ipe 120
56x10,04 kg/m= 582,4 kg
Archerecci correnti = sezione 50x30x 1,5 mm
17 m x 14 pezzi = 238 metri
238x 4,27kg/m= 1016,26 kg
Catene di controspinta
14 metri x 4 pezzi= 48,4 metri
Profilato ad U 100x50 = 10,6 kg m
48,4x10,6 kg /m =513,04 kg
Totale kg=2672,88 kg

I also did the accounts of the steward, in principle, it lacks something I encourage you to sottolinearmelo
Materials List:
1) # 6 external pillars h = 3 2,80+ inner pillars 120 3.80 hea
6x2,80 = 16.8 m
3,80x3 = 11.4 m
Total 11.4 + 16.8 = 28.2 meters x 19.9 = 561kg weight
truss:
14,02x No. 4 = 56 meters ipe 120
56x10,04 kg / m = 582.4 kg
current Archerecci section = 50x30x 1.5 mm
17 m x 14 pieces = 238 meters
238x 4,27kg / m = 1016.26 kg
Chains of counterforce
14 meters x 4 pieces = 48.4 meters
U section 100x50 = 10.6 kg m
48,4x10,6 kg / m = 513.04 kg
Total kg = 2672.88 kg

what do you think, how you costruireste empirically, what do you think, where I went wrong thanks for your attention and technical advice

Winds and snow load?   Cross bracing to prevent racking?  Do you have the scaffolding and lifting equipment to work on it or will it need to be rented?  Crew?  Permits cost?

the wind and thunderstorms are a problem does not snow the building is at sea level you need to rent hydraulic crane set up on a truck to hoist and lift the various materials and tools, to the jib crane you hook a special basket to perform work at height
