On a small job, the surveying process is simple because construction flows from start to finish, Andreiuk says, but on the northwest Alberta project, work happened simultaneously along differ- ent sections of the line, making data management a challenge. "We had a master list provided from the client of the approved pipe and heat numbers that were involved in the line, so basically, we are checking and confirming the order of every indi- vidual joint put into the ground," An- dreiuk says. "The biggest challenge was the volume of data and the speed with which the contractor was constructing the pipeline." Pipeline Module Saves Time in the Field Even in the worst of conditions, pipeline data still has to be collected. Increasing regulations mandate data on where a pipe was made, who manu- factured it, precisely where it is located in the ground and where welds are lo- cated spatially. This kind of data not only makes installation more safe and efficient, it also helps with monitoring of the pipeline as it ages. For the northwest Alberta pipeline project, McElhanney relied on Trimble Access Pipelines to keep track of 20,000 pieces of pipe in the project inventory, as well as strung pipe, welded pipe, pipe as-built measurements and reporting. Trimble's specialized software for pipelines includes powerful tools to collect pipe attribute data, record the relationship between welds and pipes (joints), and then, when the pipeline is surveyed, link the joint attributes to the measured welds. "Trimble Access Pipelines basically gave us all of the information, linked at the end of the day, so we didn't have pieces of information everywhere," Andreiuk says. "Each individual piece of information is linked to another. By having that organization, you can start mass producing it in spreadsheets and can manipulate the data in whatever fashion you want." Software Addresses Unique Challenges In the field, McElhanney's crews used eight Trimble Tablets and 23 TSC3 controllers with Trimble Access Pipe- lines installed on each. For the pipe as-built measurement, the team used Trimble R10 receivers. Project activities included: • As-strung pipe tally. Due to the large (over 20,000 pieces of pipe) size of the tally file McElhanney used the Trimble Tablets for this work. With the tally file uploaded to the tablet, the crew only needed to type in the pipe number and the module populated the rest of the fields, which made the task go much faster. Any errors in pipe information could be easily reconciled. A crew would tally about 100 pipes per day on average. "With the pipe tally, we would be documenting each individual segment of pipe,"
