2. Scope of Work

This procurement seeks a qualified diving contractor to conduct pile condition surveys at three specific piers in County Donegal: Machaire Rabhartaigh (Magheroarty), Ailt an Chorráin (Burtonport), and Árainn Mhór (Arranmore Island). The primary objective is to determine the current condition of existing steel sheet piles, identify any deteriorating sections, and assess required repairs. The survey will involve ultrasonic measurement equipment to determine the residual thickness of the piles.

The scope of work includes:

• Pile Condition Surveys:
• Surveying steel sheet piled quay walls above and below water level.
• Cleaning growth from the piles to enable examination of all elements from the high water level to the seabed.
• Taking readings at a maximum of 1-meter spacings from high water level to seabed.
• Taking additional readings at the low water splash zone, 500mm above and below each pile.
• Recording any holes or defects, or areas where thickness is less than 6mm, detailing the extent of the defect or thickness.
• Reporting:
• Providing a detailed report for each of the three sites, resulting in three separate reports.
• Each report must identify each pile surveyed and detail thickness readings as specified.
• Including photographs of the condition of existing piles and each defect identified, clearly referenced on a plan drawing of the piles/pier.
• The final report must be delivered in advance of Mid-October 2026.
• Project Supervisor (Construction Stage) Role: The successful contractor will be required to accept and carry out the role of Project Supervisor Construction Stage (PSCS).
• Compliance: All diving operations must comply with the Safety, Health and Welfare at Work (Diving) Regulations 2018.
• Estimated Survey Volumes:
• Machaire Rabhartaigh (Magheroarty): 64 piles to be surveyed (from 388 total).
• Ailt an Chorráin (Burtonport): 39 piles to be surveyed (from 143 total, plus 10 double piles from 30).
• Árainn Mhór (Arranmore) Island: 34 piles to be surveyed (from 170 total).

The work will require operations over, beside, and in coastal tidal water. A Traffic Management Plan will be required where necessary.

3. Background & buyer context

Donegal County Council is procuring these pile condition surveys due to funding constraints that necessitate completion before Mid-October 2026. The project is part of the Council's ongoing management and maintenance of its harbour infrastructure. The surveys are intended to assess the structural integrity of the piers and inform future maintenance or repair strategies. The procurement is being conducted via a Request for Quotation (RFQ) process, indicating a need for a focused, potentially shorter-term engagement for a specific technical service. The Council encourages participation by Small and Medium Enterprises (SMEs) and suggests exploring collaborations if capacity requirements are a concern.
