Construction law is a general reference to various areas of law as applied to the design, engineering, and construction of buildings—including residential buildings and commercial buildings—as well as bridges, roads, pipelines, railroads, water transmission and distribution systems, electrical power transmission systems, sewerage systems, and other structures.

In addition to the law governing the filing and removal of mechanic’s and materialmen’s liens (also known as contractor liens), construction law includes contract law, employment law, personal injury law, insurance law, zoning law, and real estate law.

In Nebraska, construction law encompasses a wide range of legal areas as they relate to the construction industry. This includes the creation and enforcement of contracts, which are essential for defining the terms and conditions of construction projects. Nebraska's Mechanic's Lien statutes (Neb. Rev. Stat. §§ 52-125 to 52-159) provide a mechanism for contractors, subcontractors, and suppliers to secure payment for labor and materials provided. These liens must be filed within a specific time frame and in accordance with state procedures to be valid. Employment law is also a critical aspect, covering worker safety, wage requirements, and labor disputes. Personal injury law comes into play when there are accidents or injuries on construction sites, necessitating an understanding of liability and negligence. Insurance law is relevant in terms of the types of coverage required for construction projects, such as builder's risk and liability insurance. Additionally, zoning and real estate laws govern land use and the permits required for construction, while environmental regulations may also affect construction activities. Each of these areas is governed by a combination of state statutes and federal law, and they collectively ensure that construction projects are carried out legally, safely, and to the benefit of all parties involved.
