Quick Answer (30 seconds):
To avoid technical rejection and redesign loops in EPC & government tenders, submit one consistent Tender Pack (not scattered files) that includes:
1) a clean BOQ (with exact model mapping), 2) correct IES photometric files (matched to optics + mounting), and 3) a complete DIALux/Relux report (lux + uniformity + layout proof).
✅ If you share a BOQ template, road drawing, or Google Map link, our engineers can prepare a tender-ready deliverables pack within 24 hours:

What’s Inside a Tender-Ready Deliverables Pack
| Deliverable | What reviewers check | Most common failure |
|---|---|---|
| BOQ + mapping | Model/qty/specs are auditable | BOQ cannot map to IES/DIALux |
| IES photometric files | Exact model + optics + tilt | Generic / wrong optics / wrong mounting |
| DIALux/Relux report | Lux + uniformity + layout proof | Assumptions not stated / no IES reference |
| Datasheets & drawings | Spec proof + install feasibility | Missing key attachments for due diligence |
| Compliance snapshots (on request) | Tender-required docs list | Wrong set for the buyer type |
Note: final criteria always follow the tender’s stated standard and reporting format.
Who This Checklist Is For
Use this checklist if you are:
- Preparing a tender submission for solar street lighting (roadway / municipal / rural).
- Requesting design approval (lux + uniformity) from a consultant or authority.
- Comparing suppliers and need audit-proof documents, not marketing claims.
- Building a BOQ and want to prevent hidden costs caused by wrong assumptions.
Step 0 — Inputs You Should Gather First
Even strong suppliers cannot produce a valid IES/DIALux/BOQ pack without basic inputs.
A) Site & geometry
- Road type and cross-section (lanes, width, median, sidewalks)
- Pole height target + rough spacing (or your concept)
- Intersections, curves, bridges, trees/shading risks
- Any boundary limits (spill light restrictions near houses, airports, ports)
B) Targets & standards (if specified)
- Target illuminance (lux) and uniformity
- Any glare/spill/uplight requirements
- Tender standard reference (if stated)
Standards note (global):
Criteria vary by country and authority. Common references include EN 13201 (Europe) and IESNA RP-8 (North America). If your tender specifies a local standard, calculations and reporting should match it (targets, grid, assumptions, output format).
C) Practical constraints
- Rainy season / cloudy days expectations (autonomy assumptions)
- Anti-theft requirements (battery/panel risk)
- Maintenance model (local team vs outsourced O&M)
✅ Fast start: you can begin with a Google Map link and spacing concept.

Step 1 — BOQ Checklist (BOQ = Mapping + Proof)
Caption: Example BOQ mapping table (blurred for privacy).
A BOQ that wins is not just “quantity + price”. It must be auditable.
BOQ should include
- System type (All-in-One / Split / Hybrid / High Mast / Smart Pole)
- Pole height + spacing basis (or design basis if pending)
- Luminaire wattage + optics distribution (roadway optics matters)
- Solar panel & battery basis (chemistry + capacity + autonomy basis)
- Controller features (dimming profile, protections, monitoring option)
- Accessories: brackets, anchor bolts, foundation kit (if required)
- Spare parts plan (critical parts + recommended percentage)
- Warranty statement (system vs components) + delivery schedule
The BOQ Mapping Rule (most important)
Every BOQ line item should map to:
- a datasheet (spec proof)
- an IES file (photometric proof)
- a DIALux/Relux report (performance proof)
If your BOQ cannot map to IES + DIALux outputs, reviewers often treat it as incomplete.
✅ Request Tender Documents & BOQ →
Step 2 — IES Photometric Files Checklist
IES files are the bridge between a luminaire model and measurable roadway lighting results.
Caption: IES naming convention example for audit traceability.
Request IES files that match
- The exact luminaire model (not a “similar” product)
- The exact optics / lens distribution
- The mounting tilt (0° vs tilted can change results and uplight)
- The correct wattage/CCT configuration used in the BOQ
Minimum IES pack for tender submission
- IES for each model + each optics option used
- Reference naming: model + optics + wattage + CCT
- Optional: optics selection notes for roadway type
Common IES mistakes that lead to rejection
- Generic IES from a different product family
- IES not matching the optics stated in BOQ
- Ignoring tilt/mounting assumptions (especially high mast / area lighting)
✅ Request IES Photometric Files →
Step 3 — DIALux / Relux Report Checklist
Need a reviewer-style DIALux rejection checklist (what committees check first)?
→ DIALux Report for Solar Street Lighting Tenders: Reviewer Checklist →
Caption: False color map + isolux contours example (roadway calculation).
For EPC and government review, a DIALux/Relux report is your proof-of-performance.
A complete tender report should include
- Project geometry and pole arrangement summary
- Luminaire selection with IES reference
- Calculation settings (maintenance factor, grid, assumptions)
- Illuminance results (lux) and uniformity
- Layout screenshots (pole positions + calculation area)
- False color map / isolux contours
- A clear pass/fail summary vs target criteria
High mast / area lighting (extra)
- Aiming concept and commissioning notes (tilt/rotation guidance)
- Uniformity focus + boundary spill control (if required)
✅ Request DIALux Simulation Outputs →
Step 4 — Datasheets & Drawings (Audit layer)
Tender reviewers often ask: “Show the specification proof and installation details.”
Common attachments
- Luminaire datasheet (optics, wattage, protections, IP/IK if applicable)
- Controller datasheet (dimming, protections, monitoring option)
- Battery & panel basis (chemistry, capacity, safety notes)
- Pole specification sheet (if poles are included)
- Installation/assembly notes (optional but helpful)
Step 5 — Engineering White Papers (When you must prove key claims)
If your tender committee is technical, white papers help make claims explainable and verifiable, such as:
- Efficacy proof chain (chip vs luminaire vs system, real conditions)
- Smart monitoring value (fault alarms, SOC trend, scheduling)
- Autonomy logic for cloudy season (what changes, what doesn’t)
Due diligence links (for tender reviewers)
If your committee requires factory verification and project references:
The most common reasons tenders fail (and how to prevent them)
1) BOQ and design do not match
Fix: enforce BOQ mapping to IES + DIALux outputs.
2) IES files are generic or incorrect
Fix: request IES “by model + optics + mounting tilt”.
3) DIALux assumptions are unclear
Fix: list pole height, spacing, maintenance factor, targets, and IES reference.
4) Missing attachments for due diligence
Fix: include datasheets, warranty, spares plan, and requested compliance snapshots.
5) No proof path for key claims
Fix: include white papers and “what reviewers can verify”.
Hidden costs (why this matters)
An incorrect IES file or unclear DIALux assumptions creates hidden costs: redesign cycles, delayed approvals, re-installation, and sometimes replacement after site verification. A tender-ready pack prevents these failures before procurement.
What to ask a supplier (copy-paste RFQ template)
Please provide a tender-ready deliverables pack for our solar street lighting project:
1) BOQ mapping (models + quantities)
2) IES photometric files (by model + optics + mounting tilt)
3) DIALux/Relux report PDF (lux + uniformity + layout screenshots)
4) Datasheets pack (luminaire/controller/battery/panel/pole if included)
5) Warranty + spare parts plan + requested compliance snapshots
Inputs attached: [BOQ template / road drawing / Google Map link], target: [lux/uniformity], pole height: [ ], spacing: [ ].
Please confirm delivery time and any missing inputs needed.
