Q1093. What engineering standards govern major infrastructure construction contract translations?

Answered by the NYC Visa & Translation certified translation team

Major infrastructure contracts in Thailand — expressways, rail, airports, ports, power plants — are procured under standard forms adapted from FIDIC conditions, and the translation practice follows that heritage. The governing rules: for Thai government projects, the contract is a Thai document under the Government Procurement Act, and international-financed projects (ADB, World Bank, JICA) use their standard bidding documents in English with the funding agency's procurement guidelines; for PPP projects, the PPP Act framework adds its own document requirements. Engineering standards in translation: the technical specifications reference international codes (AASHTO, AREMA, EN, JIS) alongside Thai standards — codes are cited by designation, never translated; the conditions of contract (FIDIC Red/Yellow/Silver Book adaptations) have established Thai renderings for the standard clauses, and deviations from the standard form must be translated with particular care because they shift risk; and the bill of quantities and payment mechanisms (advance payments, retention, price adjustment formulae) are transcribed exactly. Practice points: the contract's language clause determines which text governs — in international-financed projects this is usually English, in pure Thai government projects Thai; variation and claims correspondence during construction needs ongoing translation with the contract's defined terms kept consistent; and dispute-board or arbitration documents follow litigation translation standards. Timing: a full contract translation takes weeks — plan by volume. Confirm the procuring entity's language clause and document requirements at tender stage.
