*Developer/Client engages a design team of Consultants (Architect who are lead consultants, Structural Engineers, Mechanical & Electrical Engineers) who complete:
-> a preliminary design for planning and costing purposes
-> a tender package for prospective contractors to bid on.
*Bidding Process (where the Client and Consultant interview prospective Principal Contractors)
*Principal Contractor is appointed who is then responsible for delivering on the finished design that used for construction purposes.
->Principal Contractor starts to engage with his sub-contractors for different works packages.
->The Developer/Client’s Consultants usually end up working for the Contractor (it’s called “Novation”), who ends up treating them like his sub-contractors (basically like shit). It’s difficult because on one hand the Contractor is paying the Consultants but the Consultants still have some sort of obligation to the Client.
->Many of the items, particularly things like cladding, lift design and mechanical and electrical services, are often sub-contractor design led anyway, subject to performance specifications given by the Client and the Consultants.
->There’s an Employer’s Agent who is supposed to administer many aspects of the contract to ensure that the Client is getting what he is paying for.
So, if Rightacres are concerned about this, then either Foster + Partners have lost the plot or the contract between Rightacres and the Principal Contractor ISG allows them to vary the preliminary design (under a “Value Engineering” exercise) and get away with doing what they want. Typically, the cheapest, nastiest shite that even a donkey could build.
Quite often Architects are deliberately vague regarding materials during initial planning stages. It gives the people who are paying for the project wiggly room in case the cost of materials etc. changes dramatically from early planning stages to procurement (this happens quite often).
It’s interesting that Foster + Partners don’t seem to be involved with the other plots. It will be very telling if Rightacres appoint ISG to do those plots too or go within another contractor.
Sir Robert McAlpine (SRM) have the contract for demolition of Marland House / NCP and are negotiating the interchange construction contract - ISG are building Plots 2 and 3 (BBC). From my limited dealings with Rightacres, they will have been driving the value engineering and SRM will be going along with it to agree a price - which makes that e-mail from Paul McCarthy all the more strange.
The whole interchange saga is a shambles from the minute the agreement was made for the BBC to use the existing bus station site - the council had been complicit in this for buying into those flashy artists inpressions when they hadn't agreed with Rightacres whether the design could actually be delivered (both to the budget at the time and by the end of 2017 which was the original stated completion date). Various rounds of value engineering followed behind the scenes - the basement was removed to save time and cost along with all the other changes discussed on here. In the background the demolition of the car park has been delayed while agreement was reached with NCP (finally agreed) with a date towards the end of the year currently being discussed for piling to start.
So what happens next will be interesting to see - I did give someone a call from SRM last week and he said that they were pricing drawings that were not yet in the public domain - maybe this means there are further changes to come as hinted in that e-mail? Whatever happens I don't think Rightacres or CCC have enhanced their reputation during this process.
