Recently, many business and government organizations have benefitted by executing projects using TOC-CCPM(Theory of Constraints-Critical Chain Project Management). In parallel, Earned Value Management(EVM) metrics have also become popular. Many organizations like US government requires that all large projects measure and report project progress status using EVM. Thus, project management in business fields such as plant construction, IT development, ship building need to integrate TOC-CCPM and EVM in oder to keep and reduce the delivery date of projects for improvement of customer satisfaction and enlargement of business opportunity. This paper proposes the scheme and case of developing the Synchro-EVM system which TOC-CCPM and EVM are connected.

In this study, fresh state properties and mechanical properties of low slump modified sulfur concrete have been evaluated in order to utilize the test results as baseline data for usability analysis of modified sulfur concrete which can be applied to slip-form method. As results, holding time of slump test was delayed under 5.0% of modified sulfur addition ratio. Also, compressive strength, and tensile strength of modified sulfur concrete were equivalent with that of plain concrete.

This study carried out field test construction by slip-form method with on site concrete batch, The results show that slip form method is good at the Quality assurance and constructability of L tyoe curbs and gutters but it is difficult for Quality control.
