Introduction:

This case study highlights a topographical survey conducted for an area at Somerset House in preparation for the London Biennale exhibition. The survey aimed to produce an accurate ground surface model to assist the installation team in safely erecting a 9-meter-high structure on an uneven floor with cobblestones. Space planning, safety clearances from the Somerset House building and its surroundings, and the avoidance of clashes with existing service features were crucial considerations.

Laser scanning technology was employed to gather precise data, including spot levels and existing service features.

Background:

The London Biennale exhibition, hosted at Somerset House, provided an opportunity to showcase various artists and their interpretations of displacement and exchange. The Turkey Pavilion, in particular, aimed to present a thought-provoking display designed by a renowned artist or designer.

Objectives:

• Create an accurate ground surface model to aid the installation team in safely erecting a 9-meter-high structure on an uneven floor with cobblestones.
• Ensure proper space planning and safety clearances from the Somerset House building and its surroundings.
• Identify and avoid clashes or conflicts with existing service features during the installation process.

Laser Scanning:

Laser scanning technology was utilized to gather precise data of the survey area, capturing detailed information about the ground surface, including spot levels. This technology enabled the creation of a highly accurate and comprehensive model of the area.

Ground Surface Model:

The survey team used the laser-scanned data to create a ground surface model that accurately represented the topography of the survey area. This model was essential for space planning and ensuring the safe installation of the 9-meter-high structure on an uneven floor with cobblestones.

Space Planning and Safety Clearances:

The ground surface model served as the basis for space planning, enabling the exhibition organizers to determine the appropriate location and layout for the Turkey Pavilion. Safety clearances from the Somerset House building and its surroundings were carefully considered to ensure the installation adhered to regulations and minimized potential risks.

Existing Service Features:

To prevent clashes or conflicts during the installation process, the survey team identified and surveyed the existing service features in the survey area. This involved mapping out the locations of underground utilities, electrical lines, plumbing systems, and any other service features that could pose challenges or safety concerns.

Conclusion:

The topographical survey conducted for the Somerset House area in preparation for the London Biennale exhibition exemplified the importance of accurate data collection and analysis. The survey results, produced using laser scanning technology, provided crucial information for space planning, safety clearances, and the identification of existing service features. The ground surface model and survey deliverables facilitated the safe and successful installation of the Turkey Pavilion, allowing the exhibition to explore themes of displacement and exchange while ensuring the preservation of the historical site.
