FORLOG AG acts as the Engineer under FIDIC conditions, as Owner's Engineer, and as Employer's Representative on infrastructure works financed by the World Bank, EBRD and ADB — design review, construction supervision, payment certification, variations and claims.
On an IFI-financed works contract, supervision is not one role but three distinct appointment models — and choosing (or staffing) the right one shapes how the contract runs day to day. FORLOG has delivered each of them on live projects across Central Asia since 1997.
A contractual role defined in the FIDIC Red and Yellow Books (2017 editions, reprinted 2022). Appointed by the Employer; administers the contract, certifies payments and makes determinations. Deemed to act for the Employer — except under Sub-Clause 3.7 (Agreement or Determination), where the Engineer must act neutrally between the Parties.
A market role, not a FIDIC contract: the consultancy the project owner engages to protect its technical interests — reviewing designs, supervising quality, checking measurement and progress. Typically appointed under the FIDIC White Book (Client/Consultant Model Services Agreement, 5th edition, 2017).
The FIDIC Silver Book (EPC/turnkey) has no Engineer at all: the Employer's Representative administers the contract. Single-point contractor responsibility, less independent administration — appropriate where the Employer transfers design risk wholesale.
Field supervision backed by contract administration that survives an IFI audit.
Verification of detailed designs against the Employer's Requirements, national norms and the financier's technical standards before construction locks them in.
Site presence, materials quality control and testing regimes, hold points, and non-conformance management — the discipline that determines lifecycle cost.
Interim payment certificates, re-measurement under Red Book bill-of-quantities contracts, and records that keep disbursement flowing.
Instruction and valuation of variations; evaluation of extension-of-time and cost claims; determinations under Sub-Clause 3.7 conducted neutrally, as the contract requires.
Supervision of contractor ESAP obligations, site health and safety, and the records IFI supervision missions ask for first.
Testing on completion, taking-over certification, defects notification period management and final acceptance — closing contracts cleanly.
Engineering design for a sanitary landfill to EU Landfill Directive (1999/31/EC) standards, tender preparation for civil works lots, and implementation support under EBRD performance requirements (Project ID 42471).
Owner's Engineer and supervision roles on municipal water networks — materials certification, pressure-testing regimes and supervision records to financier documentation standards.
Under the FIDIC Red and Yellow Books (2017 editions, reprinted 2022), the Engineer is appointed by the Employer to administer the contract: issuing instructions, certifying payments, and making determinations. The Engineer is deemed to act for the Employer — except when carrying out the Agreement or Determination function under Sub-Clause 3.7, where the Engineer must act neutrally between the Parties.
The Engineer is a defined contractual role inside FIDIC Red and Yellow Book works contracts. "Owner's Engineer" is a market term, not a FIDIC contract: it describes a consultancy engaged by the project owner to protect its technical interests — design review, supervision, quality assurance — typically appointed under the FIDIC White Book (Client/Consultant Model Services Agreement, 5th edition, 2017).
No. The Silver Book (EPC/turnkey) has no Engineer; the contract is administered by the Employer's Representative. The trade-off is single-point contractor responsibility for design and execution, with correspondingly less independent contract administration.
The World Bank and EBRD both incorporate FIDIC conditions in their standard documents for works: the World Bank under its FIDIC licence (renewed and expanded in 2023 to nine contracts, including the 2017 editions as reprinted 2022), and the EBRD's standard tender documents are based on the FIDIC Red Book 2017 (reprinted 2022). Legacy projects still run on the 1999 editions and the MDB Harmonised (Pink Book) 2010 — our Yavan case study shows a Red Book 1999 tender in practice.
We staff supervision teams that IFI supervision missions trust — and we have been doing it in Central Asia since 1997.
