Considering　the　rapid　environmental　changes,　the　transitions　to　sustainable　practices　in　the　construction　industry　is　vital　now.　Though　the　developed　construction　industries　have　already　made　efforts　to　switching　to　more　sustainable　and　environment　friendly　practices,　the　developing　countries　are　still　lacking　it.　This　research　was　organised　to　understand　the　role　of　project　management　practises　and　integrated　methods　in　the　sustainable　development　in　the　developing　countries,　for　looking　on　how　such　practices　can　help　these　construction　sectors　become　sustainable.　The　moderation　effect　of　industrial　attitudes　and　behaviours　on　sustainable　construction　was　also　conducted　to　understand　the　intermediary　impacts.　A　survey　based　on　the　snowball　sample　of　208　construction　professionals　in　Ghana　was　conducted　to　determine　the　impact　of　project　management　practises　and　integrated　methods　on　sustainable　construction.　Research　model　was　tested　by　employing　bivariate　correlation　and　multiple　hierarchical　regression　analysis　techniques,　to　establish　the　interrelationships　among　the　project　management　practices,　integrated　approaches,　industrial　attitudes　and　behaviours,　and　sustainable　construction　and　to　explain　these　constructs　in　terms　of　their　common　underlying　dimensions.　The　findings　highlight　that　the　project　management　practices　and　integrated　approaches　are　significantly　impacting　on　the　sustainable　construction　practices　in　terms　of　BIM,　Digital　Twin,　LEED,　and　BREEAM.　Whereas　the　industrial　attitudes　and　behaviours　were　found　to　be　affecting　the　project　management　practises　and　integrated　approaches　through　moderating　role　on　sustainable　construction.　The　study　was　concluded　by　suggesting　the　importance　of　sustainable　construction　practices　and　shaping　industrial　attitudes　and　behaviours　towards　such　practices　in　the　developing　construction　industries.　©　2022　The　Authors.　Sustainable　Development　published　by　ERP　Environment　and　John　Wiley　&　Sons　Ltd.
