ABSTRACT
To assess the effect of risk mitigation strategies on project delivery, this study focused on three Kenyan roads: the 27 km Nairobi Expressway (A8), the 172 km Isebania-Kisii-Ahero (A1) corridor, and the 219 km Kenol-Isiolo highway (A2). Structured questionnaires were used to collect primary data, supplemented by secondary data from reputable web sources. The analysis employed both descriptive and inferential statistics. Using SPSS version 26, a moderated hierarchical multiple linear regression model was fitted to evaluate how dynamic capabilities influenced the relationship between risk management strategies and road project delivery outcomes. The model showed the predictors accounted for 37.1% of the variance in delivery (R² = .371, Adj R² = .299). This was statistically significant, F(4, 35) = 5.167, p < .05, with the key predictor showing a significant effect (t = 6.049, p < .05). Key findings revealed that resource risk avoidance, human resource risk reduction and insurance risk transference significantly influenced road construction project delivery. While dynamic capabilities enhanced the relationship between these three strategies and project delivery, they did not moderate the effect of project control. Consequently, the study urges construction firms to deepen their application of resource risk avoidance, human resource risk reduction, and insurance transference, primarily by investing in capacity building for risk and project management.

INTRODUCTION
Background of the Study
Roads make a crucial contribution to economic development and growth and bring important social benefits (Seid, Devadoss, & Fekadu, 2019). According to Ivanova and Masarova (2019), road infrastructure is a key prerequisite for the social and economic development of any country. One of the road projects is the construction of the Nairobi Expressway Road project (A8). The initial budget estimate provided by the Kenya National Highway Authority (KeNHA) was Ksh.65.2 billion, however, the cost rose to Ksh.87.9 billion (Kimuyu, 2022). Another road construction project is the Isebania-Kisii-Ahero (A1) Road Rehabilitation project. Initial cost of the project was Sh8.5 billion but was revised to Sh11 billion after the appraisal.
Kenol-Isiolo Road (A2), the 219 Kilometers highway is another road being built in two segments: Kenol-Marua (84km) and Marua-Isiolo (135km) (Thuita, 2023). The project was initially estimated to be constructed for a period of 5 years (2020-2025) (African Development Bank Group, 2023).
The road construction project is scheduled to be completed by December 2023 ahead of schedule and without compromising on the quality according to African Development Bank president Adenisa Akinwuni (Makena, 2022). There is a need to investigate risk management strategies the companies implemented to mitigate uncertainties during the progress of road construction.
The Problem
Several studies conducted have linked risk management strategies with firm performance (Ondara 2017; Rwelamila, 2017; Akoh, 2018). Research (Githere and Sang, 2021; Mongina and Moronge, 2021) and have shown that failure of project managers together with project execution team comprising of the KeNHA Engineers, supervising Consultants, and the key persons of the Contractor to have agreed-upon procedures and framework to manage risk was resulting to cost overrun and delay in completion of road construction projects.
Although extant literature has advanced understanding of risk management in road construction, the quantitative influence of risk management strategies on project delivery outcomes within the Kenyan context remains inadequately explored. This study aims to resolve this specific knowledge gap.
