It is considered an indicator of the quality of care in any hospital building. This research assesses challenges in escape route designs in high-rise hospital buildings in Tanzania. Data were collected using the established questionnaire. The study population was 184 participants from five hospitals in Tanzania namely Muhimbili National Hospital, Agha khan Hospital, Kairuki Hospital, Rabinsia Hospital, and Temeke Hospital. Data were analyzed with Descriptive statistics and Principle component Analysis using SPSS. All of the ten domains of escape routes such as the presence of exit routes, enough staircases, and stairwells, clear directions to exit routes, presence of blockage in exit routes, locked exits, exit routes familiarity, presence of photo luminescent signs, presence of wide exit, visible exit signs and presence of smoke in stairways were established from theoretical knowledge to determine the challenges facing escape routes in high rise hospital buildings. Using the SPSS, the factor analysis through Principal Component Analysis (PCA) was conducted to determine the lesser number of factors or components which establish a dimension solution for the research. Bartlett's Test of Sphericity values shows that the variables are significantly correlated since the p-value is less than 0.05. Several factors with an Eigenvalue large than on (e>1), having four components solution model which explained the total variance of 58.24% were retained. Three variables namely the absence of wide exits, few staircases and stairwells, and stairways with smoke scored a high score of variance which indicate to have maximum effects on high-rise hospital buildings. Therefore, it is strongly recommended to maximize the size of exits, increase the number of staircases and stairwells, and other vertical circulation, and ensure exits are protected from smoke for effective escape routes performance.

Therefore, the main goal of this research is to pinpoint crucial components for enhancing Tanzania's construction management performance. Management of building construction projects has been facing many challenges in Tanzania. This has led to the rise of construction complexities which have resulted in increasing delays, increasing construction scope, cost overrun, poor project quality, and generally poor performance of the construction projects. This has created a wake-up call for the country to implement different measures to improve the management of construction projects in Tanzania. But the lack of construction management skills in people involved in the construction industry has triggered the Construction Management Landscape to be difficult and to get worse. Several factors were reviewed and grouped within ten performance groups and using questionnaires, the respondents were asked to indicate the level of importance of those factors. Using Relative Importance Index (RII), MS Excel analyzed the data obtained from the respondents. The study revealed 7 key factors for improving Construction Management. Those factors are; Ability to solve problems, Project manager leadership skills, Site climatic conditions, Cost of materials and equipment, Project construction planned time, Site condition challenges, and Lack of competent staff. It is recommended that seven (7) elements identified by this study shall be considered the substantial elements by both government and private organizations for developing the construction industry and therefore they should collaborate in investing in worker capacity building for improving Construction Management performance. The results of this study give construction managers a way to use the key elements of construction management practices that have the biggest effects on construction management performance in the Tanzanian construction industry to address issues with poor project performance and delays in project completion.

However, the current and future research trends for safety climate in construction projects have not yet been fully examined. In order to solve this problem, a systematic review of previous research findings using a social network approach must be conducted, and future trends for the safety climate in building projects must be identified. Sixty-three peer-reviewed articles were gathered to study the literature on safety climate in construction projects. A social network approach was employed using VOS viewer to look at the connections between the researchers and the article's keywords. Based on the frequency of researcher collaboration and the connections between the keywords used in the publications, five research groups and four keyword themes were identified using the social network analysis r...
