Hello What is the minimum width for a corridor in a restaurant and internal door sizes? Thank you

Thanks Sorry the beam will have padstones below I mean above the beam where it will meet the brickwork above not below.

Hello I have a 146 wide beam on a 225 wide solid brick wall, the beam is positioned directly in the middle. Is it ok to pack out below the 1st course of bricks with paving slabs used for gardens? If not are roofing tiles still acceptable? If so what tiles would be suitable? Many Thanks

I would run 3 25mm pipes within a few meters of the external stopcock. I would then install the manifold and bury. On the current 25mm mdpe would this be a suitable solution or is it advisable to upgrade to 32mm? Thank you

length of the line to the street stopcock is 20/25 meters. Im not sure on the pressure I think at least 2 bar without measuring. thanks

I didnt understand why they wanted barrier pipe as well? Are they just trying to make more money? What would be the best way to install the 3 lines if i decided to do it my self? Im thinking if I lay 3 25mm mdpe pipes and then use a 3 port end feed manifold such as the type found on...

Hello What size mains mdpe pipe would be required for 2 studio flats and 1 1 bedroom flat all on combis and with no tanks? The water company Veolia have provided a quote for a 63mm barrier pipe with a 4 port manifold which then reduces to 25mm at close to £5000! Surely a 32mm pipe would...

Many thanks

Once again thank you very much for your replies You have explained it perfectly. Thank you

To calculate for the pitch of the roof I should divide my loads by cos 0 right? When I did that for my total loads it came to 57.3 in radians but I'm guessing that was wrong? Would the load be reduced or should it increase?

Sorry I shouldn't of written in m2 it should of been kn. If my roof is 9x5m long, that's 45m2 Now if my roofs dead load is 1 kn m2 that means my roofs weight is 45 kn Now if the live load is 1 kn m2 that makes the toal live load 45kn. Therefore the total loads being imposed are 90kn...

Thanks for your replies So assuming we have 45 kn m2 for the roof load and 45 kn m2 for the live load, 90 kn m2 divided by Cos 0 would be 57.3 in radians? Which divided by 2 again to distinguish the live and dead loads would be 28.65 kn m2. Is this correct? Once again thank you

Thank you for all your replies especially jeds. Can anyone tell me the assumed loads for a roof in Kn m2, with redland 49 roof tiles and 4x2 rafters at 400 centres and 100mm of pir insulation between the rafters. Thank you
