This growth has placed increasing pressure on the local construction industry to enhance project efficiency, control costs, improve quality, and adopt more sustainable practices. At the same time, the industry faces challenges such as a limited skilled labour force, high levels of on-site activity, and strict project timelines. In response to these issues, precast concrete has emerged as a promising alternative to conventional construction methods. This research investigates the feasibility of precast concrete structural systems within the Maltese context by examining the key factors influencing their adoption, highlighting both the potential benefits and the challenges associated with their implementation. A mixed-methods research approach was adopted, involving semi-structured interviews with architects/structural engineers, and suppliers, as well as structured questionnaires distributed to a wider group of industry professionals, including architects/structural engineers, project managers, cost consultants, and quantity surveyors. In addition, selected case studies were reviewed to support the analysis of time and cost implications across projects of varying scale and structural systems. Quantitative data were assessed using percentage distributions, while qualitative data were thematically analysed using NVIVO Software to identify key themes, subthemes, and relationships. Findings suggest that precast concrete is most suitable for medium to large scale commercial and industrial developments, where repetitive design allows for mould reuse, increased efficiency, and faster construction. Smaller or residential projects face limitations due to lower standardisation and logistical constraints. Architectural typology, particularly in terms of scale, project type and aesthetics, strongly influences system selection. The success of precast depends on early design finalisation and planning, as it offers limited flexibility for late changes. Structural design remains a challenge, especially in connection detailing, due to limited local expertise. While initial costs are relatively high, long-term advantages include reduced on-site labour, shorter timelines, and consistent quality through factory-controlled production. However, certification and quality assurance vary across suppliers. Logistics and supply chain coordination are critical, requiring early planning and alignment between design, manufacturing, and site operations. Sustainability is generally perceived positively, with benefits in material efficiency and reduced site impact, although there are concerns about similar embodied carbon when compared to traditional methods. Its broader feasibility, when considered alongside cast in situ and steel systems, depends on factors such as project scale, site constraints, construction timeframes, cost considerations, and the local industry's capacity to adopt more industrialised construction methods.

It provides valuable insights into the correlation between emotional intelligence and project performance in the local construction industry, while also revealing several avenues for further investigation. As construction projects become increasingly complex, emotional intelligence has surfaced as a significant factor in achieving effective project outcomes. Quantitative research approach was used, whereby a survey questionnaire was distributed to professionals working in the Maltese construction industry. Emotional intelligence was measured using Goleman’s framework, which consists of four competencies including selfawareness, self-management, social awareness, and relationship management. Simultaneously, project success was measured using key criteria, which included cost, schedule, quality, and stakeholder satisfaction parameters. Data was analysed using exploratory factor analysis (EFA) and regression modelling. The findings indicated that although professionals within the local construction industry possess a high level of emotional intelligence, there is no significant relationship to project success. The findings indicate that although emotional intelligence may not influence project success, it still significantly contributes to enhancing effective communication, fostering team cohesion, and resolving conflicts, elements that indirectly aid in the successful execution of projects. These results add to the expanding collection of literature that relates emotional intelligence to project success and indicate that construction firms may gain advantages by employing emotional intelligence.

However, modern environmental considerations and resource limitations have encouraged the reuse of quarry waste in reconstituted stone production. This study investigates the water absorption characteristics of ‘Franka’ stone powder with particle sizes below 2 mm and evaluates how these properties influence mix design, particularly in achieving workability and structural performance without the need for compaction load. A detailed experimental programme was conducted, including wet and dry sieve analyses, pycnometer absorption tests across multiple particle sizes, Vicat consistency and setting time tests, flow table assessments, and compressive strength tests on vibrated and hand-compacted cylinders. The mixes were designed using a fixed 12.5% cement content and a 5% admixture, with variable water content adjusted based on absorption findings. The results indicate that high absorption rates of the fine Globigerina aggregate significantly impact compressive strength because of high water demand. Optimal water content, when paired with vibration, allowed the production of castable and structurally viable blocks without increasing cement dosage. Comparisons with previous local studies show comparable compressive strengths, validating the importance of water in the mix and how it effects the cured mix.

In a context where car use is widespread, the areas around schools often face problems such as congestion, limited parking, and safety concerns for children and other road users during peak hours. The study draws on direct observations, stakeholder questionnaires, and focus group discussions to understand how parents, staff, and students experience these daily issues. The findings highlight a general dependence on private vehicles, driven largely by concerns about safety and convenience. Despite existing measures such as timed road closures, problems remain-particularly in relation to enforcement, infrastructure design, and communication with the public. While many parents and staff acknowledge the benefits of walking or alternative transport, there is hesitation to move away from car use without more secure, accessible, and clearly managed systems in place. The research concludes that with better planning, stronger community involvement, and improvements to the pedestrian environment, it is possible to reduce traffic congestion and make school zones safer and more welcoming. This dissertation puts forward practical suggestions aimed at supporting more sustainable travel behaviour and guiding future policies related to school transport and urban mobility.
