Abstract

The purpose of the study was to compare the use of the Macro Light Wall Panel (MLWP) System and the Concrete Hollow Block (CHB) as interior walls in the Beacon Tower II Project in Pasong Tamo, Makati City as a value engineering project. The idea of the study was to evaluate and discuss the different quality parameters and procedures of the two wall systems together with its corresponding material and labor costs. Actual site observation was done during and after the practicum period and site visits were made in order to examine the installation of MLWP. The study made use of different tests to determine the compressive strengths, fire resistivity, and sound transmission of the two wall systems. It was found out that the MLWP has higher compressive strength than CHB provided that the MLWP has an average compressive strength of 8.2 MPa while CHB has an average of 6.13 MPa. Both materials exceeded the design strength of the interior walls of the project which is 4.12 MPa. As for the fire resistivity, results showed that MLWP has a twelve-hour fire resistance while CHB, based on former study made by Sridorungkatum and Ngourungsi, has a minimum of three-hour resistance which complies with the National Building Code of the Philippines. In terms of sound transmission, the sub-contractor conducted a sound transmission test at the Forest Products Research & Development Institute wherein the results showed that MLWP wall system has higher sound reduction index than the CHB wall system given that the MLWP has an average sound reduction index of 36.97 decibels while CHB has an average of 32.84 decibels. The sound reduction index measures the rate of sound transmission through walls which is necessary especially when privacy and demand for quiet rooms is needed. For the cost analysis of the two wall systems, material and labor costs were considered. The material cost of MLWP is Php1405.00/m2 while CHB costs Php1024.00/m2. The labor cost of MLWP is Php229.00/m2 while CHB costs Php435.75/m2. It can be observed from the values that MLWP has higher cost with respect to material cost but CHB has higher cost in terms of labor cost. Based on the results from different tests and other factors like costs and construction time, it is indeed practical to use MLWP rather than CHB. There is a direct relationship between the construction time and cost; the higher the man-hours needed in the project, the higher cost it would be.
