Construction law is an extremely specialized legal field, so it helps to have an extremely specialized legal team on your side. The best construction law attorneys practice preventative law, rather than simply responding as problems occur; when you're looking, keep out for an attorney or firm with a proven record of doing this.
It's a good idea to keep a construction law specialist on retainer if you do a lot of construction work, especially if it's associated with infrastructure like roads and pipelines, which can affect a lot of people. This will make it easier to handle problems immediately as they come up.
