Design Economics & Cost Planning

Question 1

What did you need to allow for inflation on the estimate for Dyson

Answer 1

At the time , there was a target start on site date and completion date. This was then used to find mid point of construction and gain the % allowed for inflation in the TPI

Question 2

You say you produced the estimate using in house data - how did you know this was relevant to the project

Answer 2

Dyson were a key client at that time, and so there was a number of different projects that we carried out for dyson previously. As a result I was able to use the data most applicable to this current project.

Question 3

How did you come up with the %s for the preliminaries / design fees / etc

Answer 3

Again as we had a lot of in house data on past dyson projects, I was able to reference previous projects of a similar nature and size and use these as the basis of my %s for these elements

Question 4

what assumptions and exclusions did you allow for

Answer 4

Exclusions
VAT
works by statutory authorities
Night or weekend working.

Assumptions
-That it will be competitively tendered.
