Heating / hot water design service

[MOSSEP]

Hi,

Im pricing a new build and the architect want full design calculations provided. Anyone now of a boiler manufacturer, or a software system that will present it in a nice way for them? Ideally for free!

Ive got full building plans and positions of radiators, cylinder etc..

Stars App | Heat loss calculator for any room
This should do the trick Martin.

 

[MOSSEP]

Thanks for that, I think they are also after calculations to prove correct pipe sizing as well, does Star App provide that?

 

[SimonG]

They paying for you to do that?

 

[MOSSEP]

They will if we win the tender, it's been priced into it.

 

[chris watkins]

Why not get a consultant to do that side for you ? At least you have their PI cover on the designs.

STARS does not do pipe sizing, sounds like you need the domestic heating design book!!, it will be the best £28.00 you have spend in a while, well at least since that other Friday night down at Chatham docks but we agreed not to mention that again didn't we?:gorgeous: :001_icon16:

Give them the price and say to them that when you have won the tender you will supply full details etc.

I don't see why they need them unless they are after you to design the heating system and then get the cheaper plumber to do the work.

 

[stevetheplumber]

i would just specify the bs its designed to bugger giving them the details

 

[missplumb]

no design engineer would hand over their calculations, especially to an architect. They either dont trust you to do the calcs right (in which case id say your not gonna get the job and are just there to make up the tender applicants) or want them to give to someone and have you do all the work for them for free (and you still dont get the job)

sounds like the architect wants someone to do his job, from my experience they or their consultant hands over their spec for you to price up for tender, not the other way round.

Not if the project is being let on a D & B basis & what would an architect know about heating designs they only just about understand how a house goes together LOL.

Clients don't want to pay for a consultant any more thats a fine cos we can do it for a fee.

As I have read it so far in the post I don't think Martin is going to give them the designs until they have a contract i.e. won the tender, unless I have got it wrong ?

 

[Chalked]

Just put £500 on the job. If you get it pay for a professional to do it for you?

 

[lame plumber]

I must be working for rich folk or ones with no sense

 

[missplumb]

a design engineer wouldnt get out of bed to design and spec a full house build for £500.
Chris - as i read it, the architect want OP's calcs returned with their tender for the job.

 

[Ermintrude]

Don't waste more than 3 hours on this mess. Architect just out of school or your gonna get stitched up

 

[MOSSEP]

The design info is not expected until the job is won, Chris has read it correctly.

its only a small house, probably 8 rads and ground floor underfloor heating, nothing fancy.

I don't remember you charging me for that?!

 

[chris watkins]

I don't remember you charging me for that?!

I didn't but she did, it was a she wasn't it ? so difficult to tell, but there I go again shooting my mouth off.

So come on Martin is it a D&B or are you being asked for design proof up front with the tender?

 

[MOSSEP]

Neither, been sent a tender from an architect with full plans showing what is needed, but they want all calculations if the the tender is won. The plans show pipe runs, btu calcs, rad positions etc... but no products or pipe sizes.

Ive added a few hundred to it to deal with it if I win, no great loss if I don't though, looks like a head ache anyway.

D&B then, it may be shown but you would be responsible for the design contractually.

There speaks the voice of experience.
