T The Cibitung-Cilincing Toll Road Project is a national strategic project with a development plan that will connect the Cimanggis Cibitung toll road to the Jorr 2 Toll Road. The project contract is an agreement to carry out development with the signature of both parties in which there are rights and obligations of the parties. The construction process cannot be separated from problems regarding the rights of one of the parties that make a construction claim process. In the course of the work, the contractor has the right to submit a claim if there is an implementation beyond the control of the contractor that causes losses to both parties. One of the construction claims is a claim for submitting an extension of time and additional work costs. This study aims to analyze the factors that cause claims on the Cibitung- Cilincing Toll Road project and how to solve them. The analysis of the causes of claims begins by collecting various journals regarding the causes of claims and obtaining general causes of claims, then conducting analysis by collecting field data and conducting interviews with the contractors of the Cibitung-Cilincing Toll Road Project using the Root Cause Analysis (RCA) method. Finding the root of the problem with this method produces a Fishbone diagram which will help find the root of the problem from the Contractor and Project Owner's side. The results of the analysis show that the causes of construction claims are in terms of contracts, design planning, coordination relations (humans), in terms of materials, in terms of equipment, and in terms of land and utilities. From the four causes above, it can be concluded how to settle claims, namely by planning a settlement plan for project owners and contractors and making an internal project schedule for contractors with an integrated system between parties in the field.
