Contractor Tender Designs (IFT)

Forte can provide designs as follows at this stage: 
1) as part of Employers tender package
2) as part of contractors tender submission (if Employer’s tender lacks a sufficiently detailed specimen design)

  • Site Layout Plans & 3D Modelling
  • Indicative Road & Hardstand Profiles
  • Foundation Dimensions & Volumes
  • Cabling and Trench Design and Routing
  • Substation layouts and specifications
  • Cut – Fill Analysis
  • Bill of Quantities & Cost Schedules
  • Draft Technical Specifications

Forte Value: Contractor’s often face difficulty determining suitable quantity and construction complexity variables for their commercial calculations to form their tender submission. Forte alleviates this difficulty by providing high-accuracy tender designs and models, methodology advice, BoQ formulation, and, if required by the client, full cost estimations based on our extensive market experience.

Tender Design Review

  • Foundation Designs and Reports
  • Road designs plans, sections and reports
