The top ten main causes identified using RII from the respondent selection, that includes improper construction methods implement, low level of equipment-operator's skill, late in revising and approving design documents, late procurement of materials, low productivity and efficiency of equipment, change orders by owner during construction, delay in material delivery, low productivity level of labors, ineffective planning and scheduling of project and delay to furnish and deliver the site.
