Diamond Trading Company Botswana - diamond sorting house

Diamond Trading Company Botswana (DTCB) is a 50/50 Joint Venture partnership between the Government of Botswana and De Beers. It is the world’s largest and most sophisticated diamond sorting and valuing operation. DTCB sorts and values Debswana’s production from Jwaneng, Orapa, Letlhakane and Damtshaa mines.

With further development of the Botswana downstream diamond industry, more Botswana will benefit from employment opportunities created in the industry. This shows a rapid expansion of the local downstream diamond industry. The downstream activities will add value to the local diamond industry through cutting & polishing of diamonds and ultimately manufacturing of jewellery which will develop core competencies for adding higher value.

The client, Debswana / De Beers Botswana, required a world-class, high security diamond sorting house, having a gross superstructure floor area of approximately 21000m2, together with a basement area of approximately 10000m2, to accommodate and facilitate the functions of the Diamond Trading Company Botswana (DTCB).

Turner & Townsend’s contribution

An alliance or partnering contractual arrangement for the post contract work was adopted between the client, the contractor and the consulting team. Turner & Townsend provided cost management services on this land mark project from commencement to close out. Our work included, production of cost estimates, production of tender documents, evaluation and reporting on tenders, participation in deliberations to formulate the Project Alliance Agreement and the Target Outturn Cost and construction-phase cost management.

Making the difference

Turner & Townsend carried out monthly valuations, site measurements, earned value analyses, detailed cost reporting and the preparation of a final account.

The project was completed within budget with only a relatively short delay in achieving practical completion. Users and stakeholders have all acknowledged the success of the team in procuring an ultra-modern, hi-tech facility which we at Turner & Townsend are proud to be associated with.
