The study aimed at assessing the implementation of sustainable procurement of
works in public sector with a case of Tanzania Airports Authority. Specifically, the
researcher aimed to find out the extent in which Public Sector practice sustainable
procurement of works. The researcher adopted a case study design with the sample
size of 70 respondents that was selected by using simple random techniques and
purposive sampling techniques. The questionnaires were circulated of which 65 were
received. Data collected were analysed quantitatively and qualitatively through
descriptive statistics and multiple regression model by the help of Statistical Package
for Social Sciences (IBM SPSS version 25). The study found out that
implementation of SP works at TAA is influenced by Top Management Support and
Procurement personnel and is determined by the presence of environmental, social
and economic factors. The study findings show that procurement practices are
implemented at Tanzania Airports Authority with partial commitment. There was
absence of sustainable procurement policy; tender documents were prepared without
consideration of social and environmental criteria. Lowest evaluated cost of bids was
still a major evaluation criterion used in selection and awarding of contracts. The
research findings further revealed that, the current Public Procurement Act of 2011
as amended 2016 has not addressed the issue of sustainability to allow public sector
to embark on sustainable procurement practice in Tanzania. The study concluded
that, it is difficult to implement sustainability practices public procurement in
absence of proper legislative instrument. Therefore, recommends the amendment of
the Public Procurement Act: Act No.7 of 2011 to include sustainable requirements
such as environmental, social and economic issues of sustainability in public
procurement. Also, formulation of sustainable public procurement policy, creation
awareness of sustainable procurement concept to the public and training of
procurement practitioners on sustainable procurement concept.
