this technology to address the most common problems faced in the construction planning process. The following question is addressed in the study: i. What are the <strong>impact</strong>s <strong>of</strong> 4D <strong>modeling</strong> on construction planning process over traditional planning methods? a. What are the benefits <strong>of</strong> 4D <strong>modeling</strong>? b. What are the shortcomings <strong>of</strong> 4D <strong>modeling</strong>? The study will be further enhanced with determining ways to mitigate the shortcomings and enhance the benefits <strong>of</strong> the 4D <strong>modeling</strong> by addressing the following subject: ii. Maximizing the effectiveness <strong>of</strong> 4D <strong>modeling</strong> for the planning process. 1.4 Thesis structure The thesis includes 5 chapters. The remaining chapters are as following. Chapter 2 describes the methods this thesis used to study the problems. Chapter 3 reviews through relevant literature and explains more about construction planning process and 4D <strong>modeling</strong> together with its implementation in construction planning. Afterwards, in chapter 4 the discussion, the findings and the reflection are presented respectively. The thesis finishes with the conclusion and recommendation in chapter 5.

2 Methodology 2.1 Deductive and inductive theory Bryman (2004) described two approaches for relating theory to practice which are deductive and inductive. In deductive method, the researchers observe, review and analyze existing theories; derive a hypothesis from it and validate it using empirical analysis. That is, deductive method begins with general ideas and ends with specific results, whereas in inductive method, the researchers perform a series <strong>of</strong> studies and observations to come up with findings which lead to the formation <strong>of</strong> a general theory. It means that general ideas are generated from specific results in inductive approach. Theory Observation/Findings Observation/Findings Theory Deductive vs Inductive Figure 0-1: Deductive and Inductive approach (Bryman, 2004) 2.2 Adopted Method The approach used to conduct this thesis is deductive approach. A topic <strong>of</strong> interest was first selected and the hypothesis was derived for this study, that is: is 4D<strong>modeling</strong> beneficial for construction planning process? In order to validate this hypothesis, study was narrowed down to addressing specific research questions. To carry out the study, the quantitative methods for collecting data were mainly used. The quantitative data collection techniques include surveys, experiments, existing statistics and content analyses (Neuman, 2006). Due to the limitation <strong>of</strong> not having a company to conduct surveys and experiments, the data was mostly collected by content analysis and existing statistics. Content analysis is a technique to examine written information, content or symbolic material e.g. pictures. The researcher first identifies a body <strong>of</strong> material to analyze, for example, books, articles, and reports or other such material. Useful relevant data is then extracted, to assist in reaching the findings. Whereas in existing statistics research, the researcher collects data from previously conducted experiments, surveys CHALMERS, Civil and Environmental Engineering, Master’s Thesis 2012:27 5
