Hi A Yusuf,

Usually Design Fees for stuctural engineering work are about 10%. Total Fees for Engineering, Procurement and Construction Management - EPCM - could run to 20% of Total Contract Value.

Try www.eng-tips.com for further details.

We have 6 or more Engineering Consultants in Perth West Australia who could run up a Fees Proposal for the Ore Storage Tunnel on request.

Try the following

1 - Steelwork say 30 kg/m2 at going rate of $8,000 AUD per ton

2 - Concrete say foundations - 0.5 m3/m of wall say $500 AUD per m3

3 - Floor - say 150 mm thick concrete

4 - Concrete curb wall - say 1 m high by 150 mm retaining wall

5 - Catwalk - 20 kg/m2 steel

6 - Electrical - to be advised

That should give you an overall pictute of what is involved [but I am taking a wild guess at the rates].

If this is just to prevent the contaminants and hazardous dust from blowing from the stockpile then the answer is simple. If it is outdoors or indoors all that should ever be required is to coat the stockpile with a flexible film that prevents any blowing and dispersion of the fugitive dust. That is being accomplished now by a large number of similar companies using Dust Stop which is also certified as 100% environmentally friendly and this is something that you will soon be faced with by the new regulations coming into effect soon and already in effect in many jurisdictions. Dust Stop can do what you need and the information is found on the web site at www.cypherltd.com under Dust Stop.
