How many feet of 2" DB2 can a contractor lay per hour? I've got a 6600' run of conduit with pull boxes that I need to estimate install time for.
I figure contractor spends an hour pissing around ordering parts & pieces, an hour to pick up the conduit and get to site, have coffee & a wizz, talk to the hoe operator, tail board meeting... So perhaps 6 man hours burned before any pipe hits the trench at the beginning of the project. 2 guys (or girls, don't want to be sexist about this) start installing conduit working with bobcat guy sprinkling bedding sand that they spread around a bit... and they go at it all day. I'm not wondering about time to install the pull boxes, assuming they're already installed I'm thinking 10 minutes per 10' piece that will account for a bit of messing around entering pull boxes, corners, bedding, smoke breaks... In an 8 hour day they might only lay pipe for 7 hours so 420' per day so I'll call it 15 days.
The numbers seem high but this is a narrow road up a mountainside that will be unpassable during the install so one of the guys installing will be hoofing pipe up the road a fair bit. I'm thinking it will be much slower than highway side install in a shoulder.
Do these numbers have any resemblance to reality?
TIA
