Coping with the Information Age: Development of a Data Flow Diagram-Based Knowledge Management System for Mitigating Delays for Construction

Abstract

The construction industry adopts itself to the paradigm shift of today's technology as evident in the numerous researches being conducted to create a more sustainable process and risk-resilient systems in management of projects. In this study, the documentation system of private construction companies in the Philippines served as the primary focus with an intention to scrutinize and improve the data management system of these construction projects. Data was gathered from three(3) different companies (A, AA, and AAA) involving six of their ongoing projects. After the conduct of two(2) Likert Scale surveys, contractor-based factors are the most common delay issues in projects namely financial difficulties and late deliveries with a mean of 4.32 and 4.26 respectively; while, communication and proper data management were deemed by the respondents as most effective with a mean of 4.66 and 4.51 respectively. The analysis of variance from the three companies does not show much difference as it was able to meet the 95% confidence level implying that the hypothesis is valid in all three sets and same as the analysis of variance among the three construction entities - contractor, client, and consultant. The DFD-Simulation Method showed a significant 2-3 days of schedule improvement valued from Php 10,000.00 - Php 125,000.00. Therefore, construction data management needs to apply DFD and other emerging technologies such as BIM to improve construction delay mitigation.
