A common question from project managers, lenders, and counsel is "how long does an EIAS translation take for an Ecuador mining project?" The honest answer is "it depends on the file, but here is what we see in practice."
This note is a working reference based on the timelines we have hit on recent Ecuador mining projects. It covers the four file types we translate most often: EIAS packages, feasibility studies, compliance audits, and concession documentation. The numbers below are delivery times from "source file ready" to "delivered translation," assuming a single round of clarification questions and one final review by the client.
The baseline numbers
| Document type | Typical size | Typical delivery |
|---|---|---|
| Single EIA or ESIA report | 200–400 pages | 10–18 business days |
| Full EIAS package (EIA + PMA + appendices) | 400–1,200 pages | 18–35 business days |
| Feasibility study | 400–700 pages | 16–28 business days |
| Annual compliance audit | 150–250 pages | 8–14 business days |
| Concession + permit package | 80–200 pages | 6–12 business days |
These are the typical ranges, not the floor. Several factors push the delivery date in either direction.
What shortens the timeline
- Editable source files. A Word, Excel, or InDesign source that is clean, complete, and not password-protected. A 300-page EIAS in editable Word delivers materially faster than the same file as a scan.
- A prior Spanish source. If the company has a prior EIAS in Spanish, we can reuse the defined-term glossary and the project-specific terminology. This is the single biggest acceleration lever.
- Defined project glossary. If you have a preferred English terminology list — project names, concession codes, defined acronyms — sending it with the file removes 2–4 days of back-and-forth.
- A focused first review. If the recipient (lender, counsel, advisor) reads the first delivered section and confirms the terminology matches the source, the remaining sections deliver against the planned cadence.
- Single point of contact. A project manager who can answer terminology questions in under 24 hours keeps the translator from stalling on a single term.
What lengthens the timeline
- Scan-heavy source files. Scanned PDFs of permit documents, environmental reports, and signature pages need OCR before translation. A 200-page file that is mostly scans adds 3–5 days of preparation.
- Bilingual documents with prior bad translations. If a prior translation introduced defined-term drift or unit errors, the new translation has to be re-glossaried before work begins.
- Multiple reviewers with conflicting feedback. A first review by counsel, a second by the environmental manager, and a third by the lender's advisor — each with different terminology preferences — adds a full reconciliation round.
- Format-heavy tables, drawings, and annexes. Mining reports often include geological tables, drill logs, and figure-heavy annexes that need careful handling. A feasibility study with 1,000-line resource tables takes longer than the same word count in a narrative report.
- Rush without a glossary. A "rush" timeline without a glossary means the translator is making terminology decisions on the fly, and the receiving party may need to rework the file after delivery.
The realistic process
For a typical 300-page EIA with a project glossary in place:
- Source review (1–2 days). We read the file, confirm the structure, and confirm the glossary against the source.
- Translation (5–8 days for a 300-page EIA with a glossary). Mining-specialist translator, with a second reviewer for consistency.
- Final review and delivery (1–2 days). Cross-check against the source on tables, units, and defined terms, deliver electronically.
- First-review window (3–5 days for the client). A focused review of the executive summary, the impact identification, and the monitoring commitments.
A 300-page EIA delivered in 10 business days is realistic with a glossary. Without a glossary, the same file typically takes 14–18 business days, with a higher risk of terminology drift.
What to send with the file
To get the shortest realistic delivery, send:
- The source Spanish (or English) file, in editable format where possible
- The prior EIAS in either language, if the company has one
- A defined-term glossary for the project (project names, concession codes, monitoring parameters)
- The performance standard reference (IFC PS, World Bank ESF, EBRD ESP) if the package is going to a lender
- The recipient's terminology preferences, if known
A translation that has all of these inputs delivers faster, reads better, and is accepted on the first review.
The biggest avoidable delay
The single biggest avoidable delay on EIAS translations is the post-delivery re-glossarying round. A file that delivers fast and reads well on the first review is the goal. A file that delivers fast but needs a second pass to fix terminology drift costs the project a week of back-and-forth.
If you have a deadline tied to a lender, a regulator submission, or a transaction closing, send the file as early as possible with the prior EIAS, the project glossary, and the recipient's performance standard reference. The first delivery will hold.
