Competency-based assessment of the civil engineering program under the new learning modalities: A multi-perspective triangulation analysis

In a rapidly advancing world, civil engineering students should be able to adapt to the dynamic competencies valued in the industry to succeed in their future careers. This study aims to fill a research gap by analyzing the competencies acquired through the new learning modalities. Its significance extends to multiple sectors, providing growth for students, improving teaching methods for faculty, informing hiring decisions for construction companies, enhancing educational systems for universities, assisting curriculum programmers, and offering insights for future researchers. The study examined the competencies of civil engineering students under new learning modalities, exploring self-assessments, professors' perspectives, and construction companies' viewpoints, it also uncovered the intricate relationships between these perspectives. Additionally, this study compared the acquired competencies of students with the valued competencies in the industry. This study utilized a mixed-method research design, specifically triangulation. The study surveyed eighty (80) students, sixteen (16) faculty members, and ten (10) construction companies through a purposive sampling technique. Validated questionnaires and structured interviews were used as research instruments. Furthermore, the quantitative and qualitative data were analyzed accurately and systematically. The findings of the study revealed that civil engineering students possess a strong foundation in ethical responsibilities, teamwork, and leadership, as mentioned by the participants, who believe that ethical responsibilities have been instilled in students since childhood. However, the students also demonstrate a need for further development in engineering mechanics, design, and managing risk and uncertainty. From the perspective of professors and companies, students need to have knowledge and mastery of design, risk, and uncertainty which are valued competencies in the industry. In conclusion, the study emphasizes the significance of aligning academic and industry expectations for preparing successful civil engineering students. While competencies from new learning methods are generally effective, technical improvements are required. Varying perspectives highlight the need for an enhanced curriculum to meet industry demands, with strong support for the formal integration of hybrid learning.

Waste Plastic Brick

Brick is one of the very common and important construction materials which is used in all masonry work. A large land area is used. for acquiring the clay for brick making. The word replacement has become a very common thing worldwide. More land area is being acquired for clay in brick making. This paper outlines the utilization of plastic waste in construction industries. Plastic waste use in the construction industries is increasing rapidly and the world’s recycling rate of either plastic waste specifically is still low. The production of bricks is non-eco-friendly and a waste-generating process because of the greenhouse gases released. Utilizing plastic as construction materials, especially in the production of bricks is one of the promising steps towards sustainable resources and waste management. Plastic waste can substitute either partially or completely one or more of the materials in brick production. To make this reduced replacement of waste materials can be done. This was then molded into bricks with a mold of size 190x90x90 mm. Further research based on recent research and a better understanding of the utilization of plastic waste in bricks is needed to produce high-durability and quality bricks as well as to achieve the optimum balance in all aspects, especially in terms of cost and functionality.

Proposed Design of the Existing Dike along Sitio Delta, Consuelo, Macabebe, Pampanga

Dikes are structures that prevent overflow to the inland ground and must be built on a continuing basis to protect flood-prone areas. To have a long service life, dikes must be built according to design standards, and failure to do so my result in the structure failing. Failure on some parts of Consuelo Dike motivated the researchers to come up with the study. The present project study aimed to propose a redesign of the dike along Sitio Delta, Consuelo, Macabebe, and Pampanga. Before determining the parameters needed in designing, the researchers identified first the causes of the failure of the dike through the gathered or collected data from the respondents’ observations and experiences. Then, researchers assessed the present condition of the existing dike through site analysis and actual observation. The data collection procedure was carried out by obtaining secondary data from the Municipality of Macabebe and the Department of Public Works and Highways (DPWH). This includes the result of soil sample tests, past maximum flood levels, river profiling, geotechnical investigations, and other tests made regarding the dike. The findings of the study helped the residents of Barangay Consuelo deal with the consequences of dike failure. The findings provided useful data to the Local Government Unit of Macabebe, Pampanga, which can be used as a reference and guide to the development of the existing Consuelo Dike design. Researchers may use the findings to identify additional areas of concern and recommend appropriate interventions.

An investigation study on pulverized eggshell as a partial replacement of cement for non-load bearing concrete hollow blocks

In order to minimize the problem and develop a useful, practical, and affordable construction material, the researchers discovered the use of waste materials. Because of the scarcity, the researchers are motivated to utilize the solid waste generated by households and companies that use eggs in their production of goods. The researchers propose using Egg Shells to develop an alternative cement for the concrete mixture. The study has three main objectives: (1) to determine the 7-day, 14-day, and 28-day compressive strengths of concrete when pulverized egg shells are used as a partial replacement for cement; (2) to determine the water absorption percentage of the concrete when the pulverized eggshell is used as a partial replacement for cement in concrete; and (3) to perform a cost analysis in the preparation of a concrete mix with pulverized eggshell as compared to the standard concrete mixture. The study involves cost analysis and two tests: compressive strength and water absorption. To achieve the result from the compressive test, the researchers made CHB specimens consisting of nine for each experimental (5%, 10%, and 15% cement partial replacement) setup and nine standard concrete mixtures for each different curing age (7, 14, and 28 days). Based on the analysis of the findings, the researchers conclude that eggshells can be a partial replacement for cement for non-load-bearing concrete hollow blocks. The samples were tested using the Universal Testing Machine (UTM), and the results show that the concrete samples with 10% replacement of PES have higher compressive strength than the standard concrete samples, all of the specimens have passed the ASTM C129 standards in both the compressive strength test and the water absorption test. Also, using pulverized egg shells can reduce the cost of the project. However, only a 10% replacement of eggshell is highly recommended.

PROJECT RESCUER: Response to Community Underlying Earthquake Risks from the Unheeded Discovery of Lubao Fault through Awareness Assessment and Modification of Existing Evacuation Plan

Modification of evacuation systems is sometimes hindered by restrictions that include the lack of information and publicity regarding the new discovery of an environmental concern such as a fault line. The safety and well-being of residents can become significantly affected as a result of these constraints. The main purpose of this research study is to assess the sense of awareness of the local residents in Brgy. Baruya, Lubao, Pampanga towards the discovery of the Lubao Fault and to propose some modifications in their existing evacuation plan. A survey questionnaire was administered to the 357 residents of Barangay Baruya who were extracted through the use of a simple random technique. The results revealed that the focused population stands to disagree that they know the Lubao Fault and its attributes in terms of the highest magnitude and the underlying risks it can produce. Moreover, a structured interview was conducted with the Lubao Disaster and Risk Reduction Management Office (LDRRMO). The summary of transcribed answers indicated that they have an available general evacuation system and do not hold separate evacuation procedures in an earthquake situation. The community of Baruya was not thus far given the particular earthquake preparations that are purposively intended for the potential strike of the Lubao Fault. The Jose Abad Santos Avenue and the Lubao Bypass Road were set to be the routes of evacuation mobility. Available rescue vehicles and the aforementioned road networks were optimized in three cases. Open safe spaces and danger zones during earthquakes were identified through community evaluation and utilization of the HazardHunterPH tool. The proposed safety signages were provided with specifications. Overall, the areas covered by the modification in this present study are all open for integration into the future earthquake evacuation plan of Lubao, Pampanga.

Flood mitigation system: Proposed permeable concrete road and drainage on Parian, Mexico Pampanga

When water overflows onto normally dry ground, flooding occurs. Heavy rains, clogged drainage systems, and occasionally failed levees or dams can all result in flooding. This study was conducted to calculate the maximum load-bearing capacity of the permeable concrete used in the road and drainage system and to test the infiltration rate of the permeable concrete. To identify the major issue of water stagnation and to provide a solution, a thorough investigation was conducted in the area, focusing on the Barangay Parian Mexico, Pampanga. In order to support the study and determine the appropriate mixture ratio for permeable concrete, data were gathered and analyzed. Following the data collection, a mixture with a 1:3:0 ratio of cement, aggregates, and water was produced. Using two sizes of coarse aggregates 1 inch and ¾ inch it was cured for seven and fourteen days, respectively. The compressive strength of the porous concrete was measured once the curing process was complete. The results for the 1-inch size gravel after curing for 7 days varied between 996 to 1279 PSI on average. However, the results of its 14 days of compression testing ranged from 900 to 1360 PSI on average. On the 28 days of curing the average strength is between 1111-1505 PSI. Upon trying the use of ¾ inch size of aggregates, the results of its compressive strength under 7 days curing was averaging from 1009 to 1137 PSI. Lastly, the compressive strength of 3/4-size gravel after 7 days of curing was between 1009 to 1137. Due to its increased infiltration capacity of 1312.982 inc/hr, 21.883 inc/sec, or 555.829 mm/sec, 0.556 m/sec, permeable concrete has a greater potential to be used as a solution to minimize flooding difficulties. The permeable concrete road must, however, adhere to the required standards for provincial highways because the planned location is a provincial route. However, permeable concrete has a high likelihood of being used to reduce flooding problems in terms of infiltration. The results from the compressive testing machine did not meet the minimum requirements for a provincial road's maximum load-bearing capacity.
