“White lining” for Utility Locate Markings

June 06, 2010 By: Tom Davis Category: Latest Changes, Underground Utilities

2004-03-23 locates on LA MFN and L3.JPGOne way to limit the extent of the multi-color painting of the public streets and sidewalks is a practice called “white lining”. That could reduce the damage caused by wide-area painting when only a small area will be excavated. How it works is that the contractor who knows the area to be excavated delineates that area with white chalk (preferably not white paint even when a water base) by marking small “L” shapes at the corners. Then the locate crew only adds their markings inside the “box”. But, it is not that simple.

Required Graffiti or Utility Locate Painting?

April 18, 2010 By: Tom Davis Category: Misc Urban Infrastructure, Sidewalk Features, Underground Utilities

CIMG7793.JPGState law in Texas requires someone digging in the public rights of way to call “One Call” who then notifies all utilities the area where digging may occur so the utility can mark the locations of their underground facilities. That is a good as it preserves the services expected by the utility’s customers and the utility does not have to make repairs thereby increasing the cost to the customers. It also protects the workers doing the excavation as, for example, hitting a high-voltage duct bank is not a healthy thing.

But the issue is in the application of the markings. There are published guidelines for the style and frequency of the markings as well as the color. The color indicates the business type of the utility, e.g. telecommunications, power transmission, natural  gas. The frequency of the marks can remove all doubt about the location as well as remove all value of the classy, upscale look paid for by the public.

This pRemoving ATT cables and poles after placing cables in underground conduit.ost is to relate the process we went through to remove ATT’s cable draped between short poles from the sidewalk. If you are considering a similar improvement be warned that ATT is only one of the communication companies that often have cables on poles. Removal of each cable will take you through a similar process but each company will have its own quirks.

The process for the relocation on Crawford Street from Preston to Commerce (map) was as follows.
