| What are those colored markings in my yard and on the street that seem to just appear overnight? Most likely those colors that you see are an important piece to the construction process. They are either from a land survey or from a Utility Locating Company. The markings may indicate that there are cables or pipes buried under ground in an area or show the property lines and construction easements. Any time a contractor or home owner is going to perform work that requires excavation of the land he is required by law to contact the local Utility Locating Company, also known as Miss Utility, before the project starts. The reason behind this is to protect the life of the people doing the work and to prevent any accidental damage to the public infrastructure that we all depend on. The service is free and contact should be made at lease 48 hours before excavation is scheduled to begin. In northern Virginia the number to use is 1-800-552-7001.
