I need to periodically measure/monitor the roof/walls of a 150 year old church for lateral movement (spread), over time (possibly for years). The walls are stone masonry and the roof is framed with timber trusses that appear to have had some modifications at some time in the past. The stone masonry at the top of the walls has reportedly been repaired a number of times over the years, to deal with spreading of the eaves. There is no written documentation or drawings for anything in this building. The eaves are at least 20' above the sanctuary floor. While measuring/monitoring could probably be accomplished internally or externally via conventional survey equipment, it seemed to me that there must be modern digital equipment available to put in place for such a purpose, leave in place, and periodically download data to a laptop etc. I looked on the web and found some info on extensometers with data loggers and linear resistance wire rotary potentiometers, but no detailed info on this equipment for new users, or any way to purchase it. This would seem to be something that a university's structural research lab would be using with regularity. I'm thinking that a wire across the sanctuary, at eave height, tied to one of these devices, would allow measuring and recording of the movement of the roof/walls (via extension or shortening of the wire) vs date etc.
Anybody got some advice on specific equipment to accomplish this task, cost of such equipment, and how/where to procure ?

Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why itâ€™s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.

Remote access enables engineers to work from anywhere provided they have an internet connection. We surveyed our audience of engineers, designers and product managers to learn how they use remote access within their organizations. We wanted to know which industries have adopted remote access, which software they are using, and what features matter most. Download Now
