- PublicationImpact Of Building Envelope Modifications On Thermal Performance Of Classrooms In Typical Schools In Hot Arid Climate Of Oman(2014-04)Ali, Alsaadi Mutaib IbrahimThis study addresses a critical oversight in environmental design and energy conservation for typical government schools in Muscat, Oman, which grapples with inadequate adaptation to its hot-arid climate, leading to a heavy reliance on mechanical systems for temperature control. This research examined the thermal performance of building envelope elements and their impact on indoor air temperature by modifying the exterior wall, roof, glazing type, window area, and orientation. Simultaneously, it provided nuanced design recommendations for optimal thermal comfort. The study was conducted in two pivotal phases. The first phase involved fieldwork measurements in three secondary schools, providing a real-world snapshot of existing thermal conditions within such buildings. The second phase employed computer simulations using Design-Builder software to replicate field measurements, explore hypothetical scenarios and modify building envelope elements. Winter indoor temperatures recorded in the fieldwork phase ranged from 24.2oC to 24.8oC, ensuring a baseline understanding of the existing conditions. In contrast, summer temperatures spanned from 32.7oC to 33.3oC, illustrating the considerable temperature fluctuations of typical schools. The recorded field measurements and the simulation results revealed a close alignment of minimal differences of less than 2oC, highlighting the study's credibility and strengthening the validity of the proposed design recommendations.
- PublicationBusiness Environment Uncertainty`S Effect On The Performance Of Three Stars Hotels And Below In Saudi Arabia: The Mediating Role Of Competitive Advantage(2024-07)Ali M, Alsubaihi IbrahimDespite the rising demand and occupancy rates in Saudi Arabia's hotel industry, the sector faces significant performance challenges due to intensified competition and supply dynamics. The proliferation of small and medium-sized accommodations has compelled hotel managers and owners to adopt competitive strategies to navigate environmental uncertainties successfully. This is particularly crucial in today's global context, where uncertainties have become prevalent across various domains of life, including the hospitality sector. This study examines the relationship between environmental uncertainty and hotel performance within the context of small and medium-sized hotels in Saudi Arabia, focusing on how competitive advantage acts as a mediator in this relationship. The study encompassed five major regions in Saudi Arabia: Mecca, Medina, Riyadh, the Eastern border, and Jazan. Employing a quantitative approach, the instrument of survey form was used to targeted group of top management personnel and accommodation owners with a sample size of 375 respondents. Data was collected through an online questionnaire survey distributed via email to identified hotels. The study garnered a substantial response, with 238 usable responses. The data was meticulously analysed using statistical tools such as SPSS and SmartPLS 3.2.1. The study's key findings unveiled a strong and significant relationship between market uncertainty, technology uncertainty, competitive uncertainty, competitive advantage, and hotel performance.
- PublicationThe Relationship Of Lean Construction With Project Performance In Construction Companies(2019-08)Albert, Cheah Chong HooiThis study investigates the relationship between lean construction, organisational culture, and project performance in construction companies in Malaysia. Its main objective is to empirically investigate the moderating effect of organisational culture on the relationship between lean construction and project performance. Despite the wide recognition on the role of organisation culture in the implementation of lean construction and their implication on construction project performance, very scant empirical studies that specifically investigated these relationships exist. Additionally, it was meant to determine the dominant culture type in Malaysia construction companies implementing lean construction.
- PublicationContractor Performance And Operational Capabilities In Long Segment Maintenance Of National Road Delivery Projects(2019-07)Bulba, Alfa TarasPerformance-based Contract (PBC) was applied in Indonesia national road as new approchment to substitute traditional way as commonly used. There are issues affect to PBC because of overloading, side friction, swampy, emergency and disputes. By this reason, PBC was modified to Long Segment Maintenance Contract (LSMC). Local contractors is force to construct and maintain in the same time at the length of territorial segment by performance measurement. However, due to of cultural changes, contractors are not realizing and optimizing their performance. The firm’s insufficient of resources and capability may have negative effect on contractor performance. Hence, maintaining LSMC by providing right determinant and operational capabilities in improving contractor performance.
- PublicationThe Properties Of Lightweight Foamed Mortar (LFM) Incorporating With Oil Palm Empty Fruit Bunch (EFB) Fibre(2019-05)Musa, MazlinaThe key players in the construction industry around the globe are very enthusiastic in producing better construction materials that are cost-effective, durable, lightweight and long lasting without jeopardizing the environment. One of the best ways in producing such building materials are by incorporating industrial waste materials such as Empty Fruit Bunch (EFB) fibre in Lightweight Foamed Mortar (LFM).
