The jobs are put up for tender by the tel co, usually jobs that have literally been "sitting on the fence" for at least 2 yrs. Road moves are when the cable network has been disassembled to accomadate construction, and temped out. We did many of these jobs. Overlays are when when a new cable is plowed in to uprade an existing network to accomodate growth. We did many of these also. The jobs are bid on and depending on the weather, the season would usually start around april, ending in nov.
The "tours" are plotted out and routes decided. FIRST CALL CONSIDERATION ARE MADE WELL IN ADVANCE! My former boss wouldn't do anything smaller than 1km.
The advance man goes out before the crew, to each job, pre surveying, calculating, taking notes. when they are far enough ahead, they can come back to meet with any associated personnel(1 call locators, drillers, oilfild reps etc) requiring meetings signatures and such
Verifies # of crossings (railroads, highways, utilities), stakes # of areas requiring drilling, makes first calls, informs foreman of issues requiring attention, sometimes calculates # reels required. Keep in mind, these plans have been engineered prior to release, so even before the advanceman, someone usually a tel engineer or even a tech has done much of the work to a degree, the advance man verifies it. Typicallly they are 2-4 wks ahead of the crew.
Understanding of basic telephone plans such as the ones provided to one call contractors is one thing, understanding constuction plans is another, and, if you work on a temp crew, you have to understand temp plans.(where cable to be disconnected, rerouting of customers to other peds etc.) I'm sure Dave72 among others can verify this.
The locator should be at least 2 days ahead of the crew. Just like you guys who do sweeping and scanning, there are two guys on the locate crew. One a real locator, the other labour. This is where the difficulty comes in, as you gotta be the guys boss(cause if he doesn't know shit, and they usually didn't) AND his buddy all day 12 hr shifts and get along back at the motel, for 2 wks on. I went through a lot of guys.
The locator comes in, gets the labour to "sniff" for culverts with the "sniffer" as thay called it. We know it as a pinfinder or magnatrack/schondstedt. This means he has to walk the whole job and mark off the culverts without going into lala land( it happens, especially after all the weed we were smoking) Hitting culverts is a huge pain in tha ass, and it sets the crew back repairing them so this way they are flagged off and the cat can avoid them. Open the ped, verify your count, account for any "odd" cable/abandoned cables. Dissconnect ALL cable grounds from the ground bar. Locate ALL the cables you can on the lowest frequency possible.(512). My personal preference for locator is an RD433, right now I'm using a subsite. They mostly do all the same things. I usually liked to "locate the ped out", starting with the route cables a few feet in either direction, then any drops, then any drops going in the direction we are plowing, finally the route cable(s) in that direction. Accuracy around the ped is required cuz you look like a dumbass if it's not when the hoes and swamper come in. No, it doesn't just shoot out in a tee, or "common trench". All cables should be labeled(prs) extending from the ped, and depths written on flags where required. Knowing where a foreman or driller or hoe guy might want to know the depth (such as any place the plow mighthave to cross it) requires you "think".
Locate ALL other utilities within the vicinity of the work. Power, gas, foreign fibre, water(usually just valves), manholes, farmer lines, anything. When you look at the constuction plans, not only do you need to know just how to locate the lines on it, you need a working knowledge of the constuction procedure. If the temp is lying in the ditch, it needs to moved out of the way of the plow, yet not on someones property. If its even just a 6pr lying in the weeds for 2+ yrs it can be a cunt to pull it up. If its over 200 good luck. All the pipelines need to be located, thus we "swept" for them, though I became fairly good at finding them without another guy later.Ped locations also need to be marked with stakes so the foreman can worry about other shit without missing one, it;s happened.
The signs also need to pounded in, evry 300m, at every crossing, 1m to CO side of every ped, at splices, end of route. We only used 3 colours of flags, pink is one. Finally the crew needs to be flagged in from the main roads, some times you also keep track of roadbans, places the transport pigs are lurking, stuff like that.
After its all done, everything should be easily visible so the crew can come in drop the cat and go.
Crew come in:
Foreman drives up first or second after or b4 the guys in the fuel truck. (whoever drives fastest) Trucks come in 2 hoes, 2 low boys, plow cat, tow cat, picker truck. Hoes go ahead, digging out peds, drills(incidently sometimes they can get away without having to do a drill by "pushing the rods" underneath the road with the hoe), plow unloades and begins. Figure 8ing every drill takes time. that means, when the plow comes to railroad or something, the cable needs to be unreeled off the plow, fed through the drill and reeled back on on the other side, the cat must be tired over paved approaches and such. Peds are set by hoe swampers, as cable is plowed, tow cat is used to both tow the plow if necessary and to drag the plow slot flat again after. Garbage has to be picked up, everything must be done according to procedure. On to the next job. Splicers come in and terminate the peds. This is a condensed version of the rolling construction crew. Want to know any more? Ask. I know my shit.
