Construction Law/HOOH


Dear Sir

Emden formula is given by: H x C x PD/ 100 X CP

where :
H = head office percentage arrived at by dividing
the total overhead cost and profit of the Contractor’s
organization as a whole, by the total turnover.

C = contract sum

CP = contract period in weeks

PD = period of delay in weeks

My query is if the average overhead cost% is H1 & average profit% is H2 according to the past audited reports.

In the above formula whether the H is H1+H2 or H1 x H2.

Please explain



Hi Sudantha
The value H in Emden's is a simple division of overhead divided by turnover to get a percentage value. There is no + or x in the formula.
You have to understand that before you can apply this - or Hudson's - formula you have to pass through at least 5 credibility gateways - one of which is demonstrable proof that the company has turned away tenders because of lack of vital staff resources.
