Engineering Surveys

Membrane Replacement

• Most underground structures have a protective membrane applied during construction to make the structure waterproof. Over time, exposure to environmental factors, harsh weather conditions, and other external elements can lead to the deterioration of these protective membranes, compromising the integrity and durability of the underlying concrete. With Vancouver being home to some of the oldest buildings with underground parking garages in British Columbia, Lyon & Phillips has accumulated considerable expertise in conducting surveys for these types of structures. Working in close collaboration with engineers and landscape architects, we meticulously gather all required data to ensure the successful and efficient completion of projects.

Building Envelope Repair

• Building envelopes are critical to maintaining a structure’s integrity, protecting it from environmental exposure and moisture infiltration. Over time, weathering, material fatigue, and other external factors can cause damage to these systems, necessitating repairs to prevent further deterioration. With extensive experience in surveys for building envelope repairs, we work closely with engineers and contractors to provide precise data. This ensures an efficient and accurate repair process, safeguarding the structure’s performance and longevity.

Monitoring

• When developing sites that have close proximity to other buildings, poor soil conditions or other geotechnical challenges, monitoring for potential movement can avoid costly loss or damage. As a preventative measure, our survey crews can accurately monitor the horizontal and vertical movement of structures and ground to record any significant changes. Our meticulous monitoring approach allows us to document and analyze any significant changes, providing early warnings that enable timely intervention and mitigation.
