IT Model to Calculate Required Equipments for Excavation Work in Construction Projects
Mahajan, Darshan A. ; Rajput, Babalu L. ;
Journal of Construction Engineering and Project Management, volume 3, issue 4, 2013, Pages 1~4

Excavation is most commonly used activity in all construction projects. All contracting agencies prefer to use bigger and heavier excavators and dumpers on site to do excavations if quantity of excavation is huge. Estimation of required number of excavators and dumpers for completion of excavation could be rather a tedious process involving repetitive calculation on which professionals spend their valuable time. As the Information Technology is highly involved in construction section there os need to have IT model for estimation of number of excavators and dumpers. The developed model is useful to calculate required equipments within short period of time. The purpose of the developed IT model is to save the time and efforts of the construction professional. The paper discusses about model which can be used on site to estimate numbers of excavators and dumpers required for completion of certain quantity of excavation within the given time. The calculation considers various existing formulas and method to generate the output. This information could certainly be useful in planning equipments on construction project sites. The tool is user friendly where any non IT background person can use it on construction sites.

Construction industry is overwhelmed by delay and often has suffered cost and time overrun. In this context, Last Planner System (LPS) has been considered as a very useful tool for the management of the construction process. Many previous studies have reported its effectiveness in construction performance. This study aims to evaluate the level of importance of the Last Planner processes in the Vietnam construction industry (VCI), and analyze the existing barriers when implementing these processes in construction management. These barriers were collected based on previous studies from International Group for Lean Construction (IGLC). A survey was carried out through questionnaire. The respondents are been experienced people in construction project management. There are four processes of LPS that were investigated including master schedule, phase schedule, lookahead plan, and weekly work plan. The results showed that master schedule is the most important item when performing a construction project in the VCI. The highest degree of agreement belongs to `owner - contractor` pair with 77.1% importance indices; whereas the lowest belongs to `consultants - contractors` pair with 63.8% importance indices. Eventually, three barrier factors were extracted from factor analysis technique with 62.2% of variance explained.
Constructability Analysis of Green Columns at the Low Bending Moment Zone

Green Frame is an environmentally friendly column-beam system composed of composite PC members that can increase buildings` life spans while reducing resource consumption. Typically, connections of PC and RC columns occur at the boundaries of each floor, which is at the upper section of slabs, causing the boundary of each floor to generate the maximum moment. Although it is not optimal in terms of structural safety to connect members at a location where the moment is high, this approach is highly adopted due to its constructability. We propose that a superior approach that employs the concept of connecting columns at the low bending moment zone can be applied to quickly and safely install green columns, the main structural members of Green Frame. Connection of green columns at the low bending moment zone can be classified into three techniques, depending on the method of reinforcing the joints, which have different connection characteristics and construction methods. Research is needed to compare the features of each method of reinforcing the joints so that the most appropriate column connection method can be chosen for the site conditions. This study aims to confirm the structural safety of the connection component at the low bending moment zone and to compare and analyze the construction duration, unit price, quality and safety performance of each column connection method. The study results are anticipated to activate the use of composite precast concrete and to be used as development data in the future.
Variation Determinants in Building Construction: Ghanaian Professionals Perspective
Asamaoh, Richard Oduro ; Offei-Nyako, Kofi ;
Journal of Construction Engineering and Project Management, volume 3, issue 4, 2013, Pages 20~25
DOI : 10.6106/JCEPM.2013.3.4.020
Variation in construction means modification of design, changes in quality, quantity of work including the alteration of standard of materials or goods to be used in the work and the removal from site any kind of material not in accordance in the contract. In Ghana, Variation order has become major issue in the construction industry. This had resulted in cost overruns, delay and in some contracts dispute, between parties. The aim of this paper was to identify the root causes of variation; effects of variations on projects in Ghana and the means of reducing the impact of variation order. The method of the study involved literature review, primary data collection, interview and closed - ended- questionnaires. Mean Scores Method was used to rank the identified factors causing variation. Analysis Of Variance Test was use to test for the significant difference between means among the professional groups. The study revealed that most causes of variation were change of design by client and inadequate working details. Establishment of oversight project management committee and flow of information were identified as means of controlling variations during project administration.
A Review of Customer Satisfaction Factors in Libyan Housing Projects
Shebob, Abdulhamid ; Shah, Raj ; Mhalas, Amit ;

Customer satisfaction and customer relationship are crucial aspect in any enterprises including housing construction projects. In general, the housing developers are facing a number of new challenges in different countries including Libya. The construction industries/housing developers need to continuously improve their products and services to meet customers` satisfaction desires and to remain in the current competitive market. This paper focuses on analysing the satisfaction factors of customers including qualityaspects of products and services in the construction projects. A framework was developed to evaluate the dynamics relationship between customer satisfaction and quality products or services, aiming to help companies` managers and policy makers to understand the needs and points of view of their customers. Apragmatic analysis was conducted to explore and analyse the customer satisfaction factors in construction industry considering different aspect of customer groups in Libya. Results indicate that there is a high demand of improvements in the contractor`s performance in terms of cost, time and quality of products. It was also found that Libyan construction companies have been forced to transform their policies after on Libyan war 2011 to focus on client and customer satisfactory policies, or say centric for the purpose of improving client requirements and turn the business into more advantageous for any company.

Currently, the Kingdom of Saudi Arabia (KSA) is the epicentre of building services engineering encapsulating the construction industry. On rise of technological advancements, engineers have the ease to thoroughly investigate engineering aspects. Not only engineers, but other stakeholders, tender related people, financial analysts work in parallel as well. However, there are some factors that are stumbling blocks in the way of progression including delaying factors in the construction industry. The paper provides deep insights of delaying factors regarding public building projects of the KSA. Collection of primary data was carried out by conducting a survey which comprised of 63 chief delay factors. Professionals related to construction industry were asked for ranking the factors in terms of their frequency of occurrence and degree of impact. Seven groups of risk factors are categorized and a correlation analysis is performed by identifying the correlation amongst the variables. Finally, 31 leading delay factors are extracted and reported.
