MARKET ENGAGEMENT QUESTIONNAIRE
Engineering Support Services
Reference: ENAS/ENSS/2373
1. Introduction
The Northern Lighthouse Board (NLB) is conducting early market engagement ahead of a planned procurement for the provision of Engineering Support Services. This exercise is designed to identify supplier interest, inform the contracting approach, and shape the forthcoming Invitation to Tender (ITT), which is expected to be issued late 2025.
It is anticipated that the framework agreement will run for four years, with an option to extend by up to two additional years.
2. Project Summary
NLB is seeking access to professional engineering support services to supplement its in-house Asset Management and Project Delivery teams. This includes:
•Feasibility studies and structural design
•Engineering inspections and surveys
•Technical reporting and recommendations
•Specification writing and bill of quantities
•Ad hoc consultancy across engineering disciplines
Services may be required for both planned and reactive work and will support the ongoing maintenance and development of NLB’s infrastructure estate.
3. Geographical Scope
Services may be required at sites across:
•Mainland Scotland
•The Northern and Western Isles, including Orkney and Shetland
•Isle of Man
Many sites are remote and exposed, requiring access by boat, helicopter, or 4x4 vehicles. Suppliers must be prepared to work in challenging environments with limited accessibility.
4. Key Challenges and Considerations
•Exposure to extreme coastal conditions (wind, sea spray, corrosion)
•Heritage assets over 100 years old with limited records
•Logistical issues (weather, transport, daylight, tides)
•Rapid mobilisation for urgent/emergency inspections
•Coordinating multiple small projects concurrently
•Strong collaboration with NLB’s internal staff and contractors
•Work primarily coordinated from NLB’s Edinburgh HQ
5. Procurement and Commercial Strategy
It is anticipated that the contract will be procured under a two-stage process, however this has not been confirmed:
1.Selection Questionnaire (SQ): compliance and capability checks
2.Invitation to Tender (ITT): technical and commercial evaluation-
•The contract will be let under the NEC Professional Services Contract (PSC)
•No incumbent handover is expected, so mobilisation will be key
•Commercial and performance oversight will be managed jointly by NLB Procurement and Assets Teams
•Key Performance Indicators (KPIs), regular reviews, and reports will ensure quality and value delivery
6. Previous Example Projects
•Rattray Head Lighthouse Davit Design
•Buildings Principal Inspections
•Chicken Rock and Bell Rock Crane WLL Assessments
•Habitats Regulations Appraisal Screening and Nations Designated Sites Screening Assessment
•Shore to Ship Power Feasibility Study
•Dubh Artach and Bell Rock Entrance Platform Designs
•Skerryvore Structural Modelling
