your project – (Procurement Routes?)

No two construction projects are the same – for instance site locations differ.

Here at Greenway Associates we believe in identifying your needs first then determine whom should be in the team.  The attached diagrams and following paragraphs are a summary of the two types common to our industry, and should give a flavour of what is available.  Note the client is referred to as the employer.

General Contracting (Traditional)


Most design / construction projects in the UK follow this route as it has been in existence since the 19th century; and involve a main contactor building what designers have specified.  Plans are drawn up as a result of the client first contacting the designer to detail and specify what is to be constructed.  It then requires a builder to interpret the instructions in order to price what has been detailed and specified.  In this process, design is separated from construction as the contractor is not a part of the team until all designing is completed.  He then offers a price to complete the works.

The advantage of this method is that the client is involved and is required to pay the team.  The client can make changes or leave the job wholly to the designer and constructor to follow the instruction specified.  However it is not to be selected if speed of erection is required – owing to the fact the contractor is not involved until the last minute.  His knowledge and expertise is not sort until after his price is given, so he can then charge a hefty figure to offer his opinion on a problem not seen during the design process.

Design and Build (Integrated)


Design and Build construction projects are quickly increasing in frequency in the UK construction industry, but has always been there in many others. Take for example the automobile or aerospace industries and the fact that the designer is also the manufacturer. It would be ludicrous for the designer to then try to find the cheapest manufacturer to build its planes. Since it is all integrated, there is no separation of design from manufacturing. The construction industry is slightly different in that the builder moves from project to project from site to site, none ever being the same.

The advantage of this method is that the client does not have to be involved and can be happy to leave the job wholly to the designer and constructor to follow the instruction specified. The contractor is in charge of the project having first been contacted by the client giving (Employer’s Requirements). The builder will then find a team including the designer to fulfil these requirements (Contractor’s Proposal). However it is not to be selected if a client likes the ability to change while proceedings are undertaken. His knowledge and expertise are included in the Contractor’s Proposal with a fixed price given, so changes to the Cost, Time and Quality of the project can levy a hefty fee for the client to pay.

There are other procurement routes but these will be discussed at a later date
