Abstract
A type-based system is widely used for cost and schedule control in the NATM (New Austrian Tunnelling Method) tunnel. This study raises several limitations of the type-based system: a broad level of control, a distributed approach to cost and schedule data, ad hoc management, and difficulty in deriving meaningful data. Integrated cost and schedule control promises a myriad of benefits on both information flow and construction management. Nevertheless, the integrated approach still seems to be a long way from common use in the construction industry because it requires considerable overhead effort to acquire, track, and analyze the integrated data. The objective of this study is to propose a new method to automate the required processes for implementing cost and schedule integration. We propose an operational-level automatic data processing system for cost and schedule integration. The proposed system consists of a real-time location system for detecting equipment locations, a wireless mesh network for transmitting the location signals to a field office, and a prototype model for transforming the signals to cost and schedule data. Technical feasibility is analyzed through a pilot project. The study offers a new approach to facilitating sensor technologies for cost and schedule integration.

In the age of limitless competition, the construction industry has been increasingly challenged to improve work performance
On April 4, a project manager calculates the change’s negative impact: the tunnel is 3.2 metres behind schedule and KRW 47 203 200 over budget. Because both cost and schedule control are implemented based on types, it can be regarded as a type-based cost and schedule control system; in short, a type system in the paper
Based on an analysis of the characteristics of excavation works, we propose an automatic data processing system (ADPS) that identifies the locations of equipment in tunnels
Summary
In the age of limitless competition, the construction industry has been increasingly challenged to improve work performance. Different levels of detail between cost and schedule data structures generate many integrated Control Accounts (CAs), which require considerable overhead effort from field managers to acquire, track, and analyze data throughout the integrated data processing. While previous effort to integrate cost and schedule data have mostly focused on building projects that consist of many elements, operations, and crews, it is not widely applied to a large construction project such as a tunnel, road, or bridge characterized by a relatively small number of information units, horizontally repetitive operations, and construction in open space. We propose a method to reduce the required number of integrated CAs and the overhead effort in data processing, focusing on excavation works in NATM tunnel projects. Because both cost and schedule control are implemented based on types, it can be regarded as a type-based cost and schedule control system; in short, a type system in the paper
