Life Cycle Cost Analysis is a key tool for determining cost effective design of infrastructural facilities for the purpose of obtaining investment value for money. This is achievable through consideration of total ownership costs over their entire life period rather than consideration of lowest capital investments only. The purpose of this study was to examine the extent of LCCA practices in the designs decision making and develop the LCC implementation logical framework model appropriate for application in Tanzania construction industry. Mixed quantitative and qualitative approach of data collection and analysis was used to search for facts to respond to research questions. The study identified that on average, 62% of interviewed building design and cost professionals are aware of LCCA existence and its significance. It was further found that, though the tool is known to that extent, only 20% of them had practiced it due to insufficient application skills, lack of financial incentive and absence of cost data management system. Despite the limitations, the study has established that on average of 62% of all interviewed respondents, are willing to apply the developed model. Among these, all cost consultants (100%) are willing to apply the developed LCC implementation logical framework methodology provided that application skills are imparted to them and financial incentive is considered by clients. Model that was developed can be used for both determination of life cycle cost of a single building component or system or both through deterministic approach. The study recommends that construction practitioners should continue being imparted with LCCA knowledge and skills. Its application should be part of a building design process and procurement policies. A study recommends further research on mitigation measures on LCCA application limitations. Buildings Developers‟ perception and acceptance of the LCC methodology and output should also be investigated to validate LCC application in Tanzania.
