As many of you may know I'm self employed and don't want to work full time.
So one of the builders I work for called me for a chat today to look at a tender he's putting together. This is the builder that builds eco homes as portable buildings.
He's considering whether to tender for 21 hotel bedroom "modules" Each one will be built as a single portable building and when delivered to site will be stacked up as three rows of 7 hotel rooms.
Then I started reading the very detailed spec. from the architect / designer. They want it all wired in LSF singles in steel conduit. Except for the AV and data wiring which can go in PVC conduit. Then they start telling me how it's all going to be powered. They want three circuits in each module. but the wording is very confusing. they don't want a CU with each module, but for each circuit to terminate in a "din rail enclosure" and them nulticore SWA back to an existing plant room. The contractor is responsible for all that cabling back to the plant room some distance away.
Then there's mention of a Ving door card entry system to be wired by somebody "qualified" by Assa Abloy to install that. Sounds like I might have to do a short course.
Then I start reading the documentation they need. Certificates for everything not just the wiring.
I'm doing my best to convince the builder it's a potential can or worms with enough clauses for some serious "contractor bashing" if they are in any way unhappy.
My concerns:
Me (or the builder) is going to have to buy the tools for steel conduit work (I've not done any since I've been self employed and in previous employment my employer had all the tools. not that I did much then)
LSF singles? that's not ordinary single conduit cable then. I've had a quick search and not found any yet.
No local circuit protection, instead multicore SWA to a plant room. I loose confidence in the architect or designer when they specify a 10A type C MCB for the lighting circuit for instance (the lighting is no more than 6 light fittings, 4 of which are specified to have LED lamps)
The "qualifications" they ask for to install the card entry system. Sounds like a basis for non payment if you are not "qualified" so sounds like a short course to get "qualified" for that.
And the size of the job. My builder reckons it would be 6 months solid work for him to build these modules and taking into account the conduit work easily 6 months work to wire them.
Your thoughts guys.
