Analysis Principles of Project Delay and Claim Disturbance 

"The Code for the Analysis of Duration and Disturbance Claims" is prepared by the British Engineering Law Society and is composed of a team of professional lawyers and contract specialists working in the engineering sector in the UK. As we all know, the UK project contract management system has a great influence on international projects. FIDIC contract model is evolved from the basis of the ICE contract model. In the international engineering community, many British engineers and contract specialists have been hired as project management consultants or project consultants, dispute adjudicators, arbitrators, and expert witnesses throughout the world, and their views and opinions greatly influence project management and decisions on disputes. Therefore, studying and understanding the basic principles and management requirements of these guidelines are of great practical significance to improve the level of international project contractors and to avoid contract risks.
