Tender Summary

Objectives

The primary objective of this tender is to engage an experienced solar water heating installation company to troubleshoot and fully operationalize an existing dual-installation system located on a military base in Limpopo province. The goal is to assess the current system for failures or obstructions, provide a costed intervention plan to restore full functionality with minimal hardware replacements, and transfer skills to SANEDI and DoD members. Ultimately, the project aims to enable full occupation and utilization of the associated buildings.

Scope

The scope includes:

  • Conducting a single site inspection on 18 June 2026 at Hoedspruit, which is compulsory for all interested parties.
  • Assessing existing flat plate collectors, hot water tanks, solar stations, freshwater stations, and associated hardware and software components, including RESOL® DeltaSol® BX Plus systems.
  • Evaluating current system issues, including leaks and operational problems, and proposing interventions to restore full functionality.
  • Providing detailed technical reports, cost estimates, and implementation plans.
  • Ensuring skills transfer and training for SANEDI and SANDF members on system operation and maintenance.
  • Completing the project within a 2-month timeframe.

Technical Requirements

The technical requirements include:

  • Experience in installing large-scale, pumped solar water heating systems for indirect applications.
  • Proven expertise with hardware and software components of the RESOL® DeltaSol® BX Plus system.
  • Ability to minimize hardware interventions during troubleshooting and repairs.
  • Capability to evaluate and repair existing system components, including collectors, tanks, and control systems.
  • Knowledge transfer capabilities to train SANEDI and SANDF personnel.
  • Compliance with security vetting procedures by the South African National Defence Force (SANDF), with all personnel being South African citizens.
  • Provision for transport and accommodation costs, as the site is remote from SANEDI’s main office.

Skills Requirements

The successful bidder must demonstrate:

  • At least 5 years of relevant experience in solar thermal system installation and troubleshooting.
  • Extensive experience with the RESOL® DeltaSol® BX Plus hardware and software systems.
  • Proven track record with references from previous projects in the solar thermal sector.
  • Qualified personnel, including system designers and project managers, with relevant certifications and experience.
  • Ability to provide detailed methodology, technical design, and project implementation plans.
  • Capability to deliver comprehensive system evaluations, troubleshooting, and hardware/software interventions.
  • Experience in training and transferring skills to client personnel.

Joint Ventures, Consortia and Subcontracting:

Most large tenders are composed of tasks in a number of different fields, and it is not always possible for a single company to cater for all of them, and therefore Joint Ventures and Consortia are formed to then submit a tender together.

Government tenders are also requiring the subcontracting of a percentage of the tender work, and the trouble is then finding Subcontractors to comply with the tender requirements

To assist companies with finding tender partners and subcontractors, you can now submit your contact details and company information on this page, so other interested parties can contact you for purposes of forming Joint Ventures and subcontracting
