Estimated Win ProbabilityModerate Fit

This tender is a price-driven opportunity focused on marine biological study and foundation removal. A winning strategy will prioritize aggressive cost management, meticulous compliance with technical and subcontractor requirements, and a clear demonstration of capability in marine operations. While social and innovative aspects are absent, demonstrating operational efficiency and reliability will be key differentiators.

Key Winning Messages

Cost-Effective & Compliant Marine Decommissioning Expertise

Reliable Subcontractor Management for Seamless Execution

Proven Capability in Offshore Environmental Services

Key Opportunities
The 100% price-based evaluation heavily favors the lowest bidder, creating a significant opportunity for cost-competitive firms.
The requirement for a detailed subcontractor list and confirmation of no replacements allows for early demonstration of robust supply chain management.
The absence of social value and innovative aspects simplifies the bidding process, allowing focus on core technical and cost elements.
Key Challenges
The tender is entirely price-driven, meaning any perceived overpricing will severely impact the bid's competitiveness.

Conduct thorough cost analysis, optimize operational efficiency, secure competitive pricing from subcontractors, and explore all avenues for cost reduction without compromising quality or compliance.

The Estonian language prevails in case of discrepancies, requiring careful review of both versions of tender documents.

Ensure a bilingual team or translation service is available to meticulously review all tender documents, paying particular attention to the Estonian version for any nuances or specific requirements.

The draft contract is in a .zip file, which is not supported for AI analysis, necessitating manual review and understanding of contractual obligations.

Dedicate significant time to a thorough manual review of the draft contract by legal and commercial experts to fully understand all obligations, risks, and terms before submission.

Ideal Bidder Profile
A marine construction or environmental services company with proven experience in offshore operations, marine biological surveys, and decommissioning/removal activities. The ideal bidder will have a strong network of qualified subcontractors, particularly divers and marine biologists, and a robust understanding of Estonian maritime regulations. They must also possess a highly cost-efficient operational model.
Key Requirements
Marine biological study and removal from the sea for the Liivi lahe wind measurement mast foundation.
Submission of a form listing proposed subcontractors, their registration codes, service descriptions, and subcontracting volumes.
Confirmation that no subcontractors subject to replacement will be involved.
Compliance with mandatory exclusion grounds and eligibility requirements.
Total cost of the works.
Key Discriminators
Demonstrated cost leadership through optimized operational planning and subcontractor negotiation.
A pre-vetted and stable subcontractor pool, explicitly confirmed as non-replaceable, instilling confidence in continuity.
Clear and concise technical proposal that directly addresses the marine biological study and removal scope with efficiency.
Social Value Opportunities
While not explicitly required, consider a brief statement on commitment to local employment where feasible during the removal phase, framing it as operational efficiency rather than a mandated social value.
Bid Focus Areas
Total cost100.0%

Achieve the absolute lowest possible price by optimizing all cost components, including labor, equipment, materials, and subcontractor fees. Conduct detailed cost breakdowns and seek competitive quotes. Ensure all indirect costs are accurately accounted for but minimized.

Tender Quality Score

This tender for a marine biological study and removal of a wind measurement mast foundation in the Liivi Bay is generally well-structured, with clear requirements and a straightforward evaluation process. However, the accessibility of key technical documents via a web link and the .zip format for the draft contract present minor practical challenges.

Score Breakdown

Legal Compliance75/100

The tender appears to comply with general procurement regulations, including the use of a proper CPV code and a clear procedure. Deadlines are reasonable, and there is no indication of disputes. The Estonian version prevailing in case of discrepancies is a standard practice.

Clarity80/100

The description of the service is clear, and the requirements are documented in separate files. The evaluation criteria are specified as relative weighting, with a clear emphasis on the lowest price. The existence of translated documents enhances clarity.

Completeness70/100

Most basic information is present, including estimated value, contract start date, and duration. However, the reliance on external links for the technical description and the .zip format for the draft contract could be seen as a slight detraction from full completeness within the immediate tender notice.

Fairness85/100

The tender is fair, with full document access (though some via link) and disclosed value. The evaluation criteria are objective (lowest price). E-submission and e-procurement are utilized. There are no apparent requirements tailored to specific companies.

Practicality65/100

E-submission and e-procurement are positive. The contract start date is specified. However, the technical description being available only via a web link and the draft contract being in a .zip format (unsupported for AI analysis) reduce practicality for bidders needing immediate access or automated processing.

•Technical description available via web link.
•Draft contract in .zip format.
Data Consistency90/100

Key fields such as title, reference, organization, value, and dates are populated. There are no indications of suspension or disputes, and the dates are logically sequenced.

Sustainability50/100

There is no explicit mention of green procurement, social aspects, innovation, or EU funding in the provided information. This category is therefore rated lower.

•No explicit green procurement criteria.
•No explicit social criteria.

Strengths

Clear description of services and objectives.
Objective evaluation criteria (lowest price).
Use of e-procurement and e-submission.
Translated tender documents (Estonian and English).

Concerns

Technical description accessible only via web link.
Draft contract in .zip format, potentially hindering automated analysis.
Lack of explicit sustainability or social criteria.

Recommendations

1. Consider embedding or providing direct links to all essential documents within the main tender portal.
2. Explore alternative, more universally accessible file formats for contract documents.
3. Incorporate specific sustainability or social value criteria in future tenders.
