Discrete Event Simulation of Multi-purpose Utility Tunnels Construction Using Microtunneling

Abstract

The Traditional Method Of Burying Underground Utilities (E.G., Water, Sewer, Gas Pipes, And Electrical Cables) Has Been Used For Many Decades. Repeated Excavations Related To This Method Cause Many Problems, Such As Traffic Congestion And Business Disruption, Which Can Significantly Increase The Social Costs. Multi-Purpose Utility Tunnels (MUTs) Are A Good Alternative For Buried Utilities. Although MUTs Are More Expensive Than The Traditional Method, Social Cost Savings Can Make Them More Practical, Especially In Dense Areas. The Construction Method Is One Of The Most Important Factors That Should Be Carefully Assessed To Have A Successful MUT Project. Simulation Can Be Used For Investigating The Different Construction Methods Of MUTs. In This Paper, Simulation Of The MUT Construction Methods Is Done Using Discrete Event Simulation (DES) To Analyze The Duration Of MUT Projects Focusing On Micro tunneling.
