Abstract - The Indian construction sector is the country’s economic engine. Because strong infrastructure provides the foundation for all other initiatives, the Indian construction industry is responsible for accelerating the country’s overall growth, and it receives top priority from the government However, due to the geographical, social, political and financial situation many construction projects in the country are prone to delays. These delays canbeavoidedbyidentifying factors andtheir sources. The main objectivesofthispaperare to find out the main causes of delays in public construction projects in Kerala. The research design was quantitative where data was collected from owners, contractors, and designers. The questionnaire is prepared using Google form, added a list of reasons for delays factor’s, each of which respondents were asked to rank on a 5-point scale. Acquired data were checked using the statistical program for social scientists, SPSS. Questionnaire survey was conducted in order to find the delays occurred in public projects in Kerala. Recommendations are suggested to avoid delays in public sector construction projects.
Key Words: Construction Management, Construction, Delays, Construction Industry, Civil Engineering.
The construction industry quite often encourages a significantpartofacountry’sGDP,reflectingoftheimpactit hasonitseconomyaswellasworkingasastrongindicator for its growth. So it is one of the most economic sectors However, delays frequently take place in the construction industry. Constructiondelayistimeexceedseitherafterthe contractdate,thatthecomponentsinvolvedandhaveagreed upon for the delivery of the project. In both case delay is alwaysusuallyacostlysituation.Constructionprojectsare complex activities, associated with large costs and long period.

Construction delays are an unavoidable phenomenonthat occurs in almost every country due to the combination of factorsconsideredabove.However,constructiondelaysare very common in most developing countries. Therefore, consideringalltheaboveandinordertoreduceormitigate thesefactors,thefollowingmeasuresmaybeimplemented inKerala:
Sufficient planning and the establishment of quality control mechanisms should be put in place to avoid design changes. appropriate time should be made to careful production of design , complete the tender documents, so as to get better the quality of contract documents with minimum numbers of errors and inconsistencies and reduce delay during several constructionstages.
Designrelatedproblemssuchaschangesindrawings, incomplete and wrong specification; clients initiated changesandgeneralchangecanhaveverybadeffecton project delivery which always leads to delay and cost overruns.Thesearereasonsthatshouldbecontrolled byagooddesignprocessandexcellentdecisionmaking.
The govt, in collaboration with other stake holders, shouldinvestinhumancapitaldevelopmentbytraining constructionworkersinappropriatetechnicalskillsto makethemgood.Bythiscountrycanconstructquality infrastructure.
Govt should also make sure that project tenders are based on experience and expertise in a particular constructionfieldandnotfullofcronyism.Ifthismade sure,itmeansthatthebestcompanywillget theproject andcompleteitwithoutdelay.
