Modelling of Safety Performance in Building Construction Projects Using System Dynamics Approach in Tanzania
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsSafety issues in construction activities are very important. Therefore, research on this topic deserves attention. The article presents a broad analysis of various factors related to safety in construction.
However, the article has some shortcomings:
- the summary lacks at least brief information about the test results,
- when listing various factors, it would be good to mention in which regions of the world (in which countries) they have the most important influence.
Apart from that, I have no comments.

Reviewer 2 Report
Comments and Suggestions for AuthorsThese were my basic questions:
The thing lacking with this paper is context.
1) How does construction contribute to GDP in Tanzania?
2) What percentage of accidents happen in construction in Tanzania ?
3) What are the demographics of the respondents to the survey
4) What types of building are predominantly build in Tanzania ?
5) What type and size of construction companies operate in Tanzania.
6) What type of accidents are most prevalent in construction ?
7) Does design influence accidents onsite ?
8) What is the current legislation concerning health and safety in Tanzania ?

Reviewer 3 Report
Comments and Suggestions for AuthorsThis paper developed a system dynamics model to understand the factors influencing safety performance in building construction projects in Tanzania. However, there are several areas that require revision and clarification before publication:
1. Proofreading for grammatical errors and typos is recommended to ensure the manuscript's readability.
2. The abstract mentions understanding complex dynamics but doesn't clearly state the research objective. For example, “This research aims to develop a system dynamics model to understand the factors influencing safety performance in building construction projects.”
3. In the abstract, the finding about "exponential" growth needs clarification. Does the model predict a continuously increasing safety performance, or an initial rise followed by a plateau?
4. In the abstract, briefly mention some key factors identified through the sensitivity analysis.
5. In the introduction, explain how System Dynamics specifically addresses the dynamic interactions within construction safety systems, which would strengthen the rationale for its use in this study.
6. A literature review section should be added (from line 88).
7. Make sure all tables and figures are cited in the text.
8. In lines 166-167, delete one “is indicated”.
9. Under tables 7 and 8, the authors indicated that tables may have a footer. Add the content of the footer if there is one.
10. The authors should check the text in lines 200 and 209 (The text continues here (Figure ?? and Table ??), if it is not needed, it should be deleted.
11. The resolution of the figures is low.
12. Two sections have the same headings, i.e. 2.2.4. Model validation and 2.2.5. Model validation.
13. The conclusion should include the limitations of the study and relevant future studies.
