Buildings, bridges, and other structures require periodic condition surveys and, occasionally, emergency inspections. Traditional access methods—such as visual inspections from grade or the use of suspended scaffolding, supported scaffolding, aerial lifts, or crane-suspended platforms—may be impractical or inadequate given the configuration of the structure, its location, historic sensitivity, or time and safety constraints. Faced with such conditions, HAL utilizes industrial rope access methods or drone capabilities to provide clients with the answers they seek.

​

These access methods offer safe and effective solutions to the limitations of traditional access methods. Often, these methods can be deployed in a shorter period of time and potentially at less cost, allowing us to efficiently respond to issues.

HAL is equipped with state of the art camera and thermal imaging drones (UAVs) which can be utilized to inspect areas that are difficult to access by aerial lift platform from the ground or not accessible by personnel. These areas can be seen on high definition cameras to see if remediation or access by personnel is required.  

Thermal Imaging sensors allow for assessment of potentially defective areas using FLIR (Forward Looking InfraRed) technology which may not be visually evident by personnel.  This can allow for cost savings if it is determined further access equipment is not required or can allow for difficult to access areas to be inspected without the significant lead time of some specialized equipment.
