Project Overview
Introduction
Underhill Geomatics provided comprehensive construction and legal surveying services for the Burnaby Hospital Redevelopment Project, supporting EllisDon throughout Phase 1 of the redevelopment. The project includes the construction of a new patient care pavilion and associated infrastructure, requiring a highly accurate survey framework to support all stages of construction.
From establishing precision control networks to performing layout, as-built surveys, deformation monitoring, and specialized LiDAR scanning, Underhill has played a critical role in helping maintain the accuracy and quality standards required for this complex healthcare facility.
Project Challenges
The construction of a large multi-storey healthcare facility presents unique survey challenges, particularly as the building progresses vertically and becomes enclosed.
One of the primary challenges was maintaining access to the survey control network as sight lines to exterior control points became increasingly restricted. As construction advanced and building elements were completed, preserving survey accuracy throughout the structure required careful planning and ongoing monitoring.
Meeting strict construction tolerances while ensuring reliable control throughout the life of the project demanded a proactive and disciplined approach.
Underhill’s Approach
Underhill established a high-precision control network using conventional total station survey techniques, prioritizing redundancy and strong geometric design to ensure long-term reliability.
Recognizing the challenges associated with diminishing access to exterior control points, our team implemented proactive control strategies early in the construction process. By strengthening and extending the control network before critical building areas were enclosed, survey integrity could be maintained throughout successive construction phases.
In addition to traditional construction layout and as-built surveys, Underhill utilized LiDAR scanning technology to perform floor flatness surveys and provide detailed quality-control information for project stakeholders.
Through close collaboration with EllisDon, our team delivered responsive survey support that aligned with evolving construction requirements and project schedules.
Notable Outcomes
