Job description

We are hiring on behalf of our client for an experienced Senior Engineering Surveyor to join their team on a major data centre construction project in Finland.

Our client specialises in delivering complex groundworks and civil engineering packages for large-scale developments, including hyperscale data centres. These projects involve extensive site infrastructure, heavy structural elements, concrete works and technically demanding construction activities where dimensional accuracy is critical.

As Senior Engineering Surveyor, you will take ownership of surveying operations and dimensional control across the entire site footprint. Your primary responsibility will be ensuring that all construction elements are positioned, aligned and installed in accordance with engineering designs, specifications and contractual tolerances.

You will establish and manage the primary survey control network, carry out detailed dimensional verification of critical structural elements and work closely with engineering and construction teams to identify and resolve alignment discrepancies before they affect project delivery.

This is a technically demanding position requiring extensive experience in engineering surveying, precision measurement and heavy industrial construction environments.

Key Responsibilities

• Establish, manage and maintain the primary survey control network across the entire construction site.
• Ensure absolute dimensional accuracy across the site footprint, maintaining precise coordinates, elevations and reference points.
• Perform complex setting-out activities for foundations, structural steel, concrete structures and other critical construction elements.
• Carry out detailed dimensional verification of structural steel installations and cast-in concrete elements.
• Verify that installed works comply with engineering drawings, design specifications and contractual scope tolerances.
• Conduct precision measurements using advanced Total Stations, GPS/GNSS equipment and laser scanning technology.
• Perform detailed alignment, positioning and elevation checks on critical structural and infrastructure components.
• Identify, investigate and report dimensional discrepancies, deviations and potential alignment issues.
• Work closely with structural engineers, site engineers, project managers and construction teams to resolve technical surveying challenges.
• Interpret complex engineering drawings, technical specifications and construction models to ensure accurate execution on site.
• Produce detailed survey reports, measurement records and dimensional verification documentation.
• Maintain accurate survey data, coordinate systems, benchmarks and control points throughout the construction lifecycle.
• Support quality assurance and quality control processes through independent dimensional verification.
• Ensure surveying equipment is properly calibrated, maintained and suitable for high-precision measurement requirements.

Requirements & Experience

• Extensive experience as a Senior Engineering Surveyor, Construction Surveyor, Industrial Surveyor or in a similar technical surveying position.
• Strong background in heavy industrial construction, large-scale infrastructure, structural steel or complex engineering projects.
• Proven experience establishing and maintaining primary survey control networks.
• Extensive hands-on experience with precision setting out and dimensional verification.
• Demonstrable experience verifying structural steel alignment, concrete structures and cast-in elements.
• Advanced working knowledge of Total Stations, GPS/GNSS equipment and laser scanning technology.
• Experience with Leica, Trimble or equivalent high-precision surveying systems.
• Strong understanding of coordinate systems, geometric tolerances, dimensional control and engineering specifications.
• Ability to interpret complex structural and engineering drawings.
• Experience identifying and resolving dimensional discrepancies within high-tolerance construction environments.
• Strong technical reporting, analytical and problem-solving abilities.
• Ability to work independently and take full ownership of surveying accuracy across a major construction site.
• Previous experience working on hyperscale data centres, power plants, industrial facilities or other mission-critical construction projects.
• Experience with large-scale structural steel installations and complex reinforced concrete structures.
• Exposure to laser scanning, 3D point-cloud processing and advanced dimensional measurement techniques.
• Experience with software such as Leica Infinity, Trimble Business Center, AutoCAD or Civil 3D.
• Knowledge of BIM coordination and integrating survey data with digital construction models.
• Experience working within strict engineering tolerances and quality assurance frameworks.
• Relevant qualification in Engineering Surveying, Geomatics, Surveying or a related discipline.
