The method used for the study was that of a survey which depends on a questionnaire with five scale of measurements of Likert scale (1 for “Strongly Insignificant” (SI), 2 for “Insignificant” (IS), 3 for “Neutral” (N), 4 for “Significant” (S) and 5 for “Strongly Significant” (SS)) to create data for the analysis. For the purpose of this study, 18 indicators from the different dimensions summarized from the literature were presented to the respondents in the form of questionnaire, and replies were collected and analyzed using Likert scale on Microsoft Excel. The research result identified 18 underlined keyfactor for sustainable construction materials. Such as, Escalation of material prices, Material and equipment cost, Labor cost, Cost of variation orders, Waste rate of materials, Conformance to specification, Availability of personals with high experience and qualification, Quality of equipment and raw materials, Wastes around the site, Climate condition in the site, Human toxicity, Empowerment & participation, Adaptability, Social value, Life span, Initial cost, Job creation, and Tourism. Commonlythe study recommends that emphasis should be given for the identified key factors especially on the top five ranked key factors for Sustainable Construction Materials.
