The study aims to estímate the total factor productivity in Saudi Arabia construction sector. Using Cobb Douglas production function. The results showed that that there is a long-run equilibrium relationship between the value of production and the factors of production labour and capital. The study also showed that the coefficient of labour is positive with a value of 0.015. While the elasticity of production with respect to capital is about 0.42 the elasticity of production with respect to the capital component is greater than the labour component and the construction sector in KSA operates in light of decreasing returns to scale (DRS).
