Estimate based on DSR (Delhi Schedule of Rates) a viable option?

Sir,

I agree with you. DSR rates give the firm basis of cost analysis.

For the tendering purpose updated material rates can be taken from the various manufacturers and the labour rates can be easily obtained from various magzins such as Builders friend and etc. By combining all these with the basis of DSR one can easily do the estimation with strong backup.

Sir,

I agree with you to some extent ie to update the items. But every six months updating is a tedious process in govt organization. New materials and new innovations are coming up. Mostly all the items are being updated and we have separate wing to look after this. But certain architectural features which varies case to case it is not possible to modulate into single unified item. Then we have to do the market analysis for the same. So DSR is being updated once in 3 years will be sufficient.

Most of the items for Constructions Industry are covered in DSR, but it still needs to be reviewed. It's very much better if the CPWD DSR officials review it half yearly and add the items which is still Non-DSR.

DSR Rates are just the base for estimates.almost all items in civil engineering are considered in DSR.This gives the basic idea for estimate.Cost Index are considered for arriving  at the market rates which will be at par with the market rates.The Nomenclature of items executed are clearly mentioned in the items which will help the agencies to quote for the items properly without any litigations.Each and every items are crystal clear so that the agencies will be very clear to understand the items properly to quote accordingly.

Yes.It is true. There is lot of recession in the private construction industries.Due to which many builders are taking contracts in government works. Due to which there is tough competetitive tenders are being quoted in CPWD and other govet areas. There is consistancy in govt works though there is recession in the corporate construction sectors.

It is not correct to say that DSR rates does not represent correct rates specially for specialised items. More tha 95% of building items or item used for civil engineering construction are avaiable in DSR. Specilaised item which are not avilable are to be analysed based on market rates. I like to suggest all to go through DSR 2007 where most of things have been updated now. There has been lot of advancement in construction practices ,lot of machination has taken place in construiction i.e use of batching plants ,concrete pumps tower cranes and sophoistictaed instruments for surveys like total station and digital theodolites. Similarly Computrers are being used for recording and printing measrement and bills and progress reporting and monitoring. All such factors have bearing on construction. Keeeping all these factors in mind DSR rates have been revised and updated. Now trend has reveresed for Govt. Bids . Overwhelmimg response are coming and competetive prices. May be private reality players have slowed down construction so agencies are coming forward for Govt. Projects. But I am of firm opinion that DSR rates are quite reasonable as compared to the market prices. Moreover Bid are evaluated based on current market prices of all materials and Clause 10CA exist in the most agreements which cater for escalation of basic materials of cement and steel. So not correct to say that govt Projects does not take off.
