The Federal Controller of Works in Bayelsa, Nwachukwu Achebe, has advised contractors who bid for projects in the Niger Delta, to endeavour to do thorough appraisal of the project sites.
Achebe gave the advice in Yenagoa.
He said that proper appraisal of sites while preparing bills of quantity and project costs was necessary in order to reduce frequent request for variation of project costs in the region.
He noted that the difficult terrain of the Niger Delta region was a major obstacle to proper execution of projects, especially infrastructure.
He said that delivery of prototype projects designed for simultaneous construction across the nation often suffered setbacks in the region as such projects often ended up being modified to suit the terrain.
The federal controller of works said such modifications required additional engineering resources as well as extra funds.
Achebe said that the Federal Secretariat project in Yenagoa, for instance, suffered several years of delays due to the 2012 flood that submerged the project site.
He noted that the difficult terrain and funding challenges had delayed the completion of the secretariat which was scheduled to be finished in 2014.
