The contractor and the developer`s designer are required to take our default form of warranty regarding the work after the conclusion of the agreement in accordance with Article 278. A motorway construction agreement allows a person or organisation to carry out proposed construction work on the motorway and usually refers to new development sites. This is a legal agreement. All anomalies that occur during the work require a formal modification of the plans. Many regulations require combined agreements under Section 278 and Section 38, as work is needed on existing roads and the resumption of new roads. As soon as the roads are completed to the required standards and the mandatory maintenance period is successfully completed, we will introduce them as a public road. These are intended for smaller works, such as improvements to pedestrian paths, new access to the bell mouth, etc.
