In simple terms
The Company is the one I work for.
The Company get a job - construction based product supply and installation following a tender and estimates, quotes supplied to the client/main contractor
The Company The Company contacts site, pre-let meetings etc to sort out when, where, payment terms etc.
The job is planned according to when the client wants the product i.e when the site is lkely to be ready.
Approx a week or 2 before the job - The Company 'contract supervisors' - our guys with many years experience installing the product and with the relevant qualifications to plan the work i.e appointed person for cranes, relevant CSCS and CPCS cards go to the site. The contract supervisors then tour the site, look at where the crane is going to sit. Agree crane positons, delivery times, type of fall protection to be used. Any scaffolding requirements, agree welfare, agree start dates, time on site and induction details etc.
All of this information is recorded on a site installation plan, risk assessments and method statements.
A day or so before the job, confirmation is obtained from site that it is ready for the installation to commence.
The subcontractor installers are then contacted (to be fair this is likely a week or so before the job for planning purposes).
On the day of the install, the subby installers will go to site, receive an induction, read the RAMS, sign the acknowledgement to say they have read it and understand the content and will work in accordance with the RAMS.
The subbys will also hand over copies of their certification to the client/main contractor for the site records.
Subby foreman conducts a pre-start check of the work area to double check that the install can start safely and to identify any potnetial problems which may crop up later.
Crane gets set up, deliveries arrive, product is installed etc.
thats pretty much it.
If there is anyone who can go to site (this is nationwide stuff) then there may be a safety inspection carried out.
We also get feedback from the client in the form of a completion sheet stating the job, any outtanding works and the performance of the subbys in terms of safety, quality of work, attitude etc.
