As- built pipeline surveying

Started this discussion. Last reply by Alyssa Fournier Jan 4. 20 Replies

Just wondering if anyone has suggestions for as-built surveys of pipelines. I'm currently on a project that contains 3 pipelines (16", 12", 6" pipes) for a stretch of about 15 miles. The ditch trench…Read more →

"Yes, there is safety protocols, which I understand to be 2 ladders every 8-10 m for multiple exits. Again, this is not practical when they are lowering in 300-500m of each pipe at a time. Welds are done above ground (except for tie-ins and…"

"I had a project similar to this with beams to be as -builted over a 50' wide trench and 15' deep. Because the contractor would not allow us in the trench he paided for a bucket truck to traverse the top ofeither slope while the rodman…"

As- built pipeline surveying

Just wondering if anyone has suggestions for as-built surveys of pipelines. I'm currently on a project that contains 3 pipelines (16", 12", 6" pipes) for a stretch of about 15 miles. The ditch trench is 10ft deep (about 16 ft wide), and we are not allowed within the ditch due to safety concerns. Previously, we used an R10 attached to a 10ft pogo, and reaching above the pipes with a 14ft painters rod, holding said rod on edge of the trench. This method was extremely difficult and could only be…See More

"Alyssa, Safety should be your priority . Canada should have some type of safety requirements for excavation, such as shoring and/or trench slopes, which would permit someone to enter the work area safely. If not, my suggestion is to have the pipe…"

"Alyssa, Knowing the time constrants for the data needed Drones are definitely out. We use a Trimble S6 Robot and have used the reflectorless mode when locating stripping along the Intersate for our DOT jobs. I will say they are accurate. The…"

"Well tell your boss you're not working in a trench. In the USA OSHA (federal safety Aholes) define a trench as being deeper than it is wide. So climb on down there and walk the center pipe. Just present it in a polite logical way."

"Hi,  If you used GPS and Total station you will be working in grid and then converting to ground at some point when surveying the welds. What about your combined scale factor? Good luck. Maurice Heter Underhill Geomatics Ltd."

Hi,

Can you use a drone ? That will enable a 3D model from which you'll be able to produce the pipes as vector data including the attribution in CAD or GIS.
