Stages　of　total　construction　process　such　as　decision-making,　design,　trading,　construction,　and　completion　of　construction　project　all　exist　risks.　From　the　point　of　project　cost　consultancy　involved,　focusing　on　and　analyzing　construction　project　risk,　effectively　identifying　and　controlling　risks　that　consultation　process　may　encounter,　can　not　only　reduce　the　risk　of　consulting　enterprise　itself,　and　reduce　project　cost　risk　of　construction　project,　but　also　reduce　the　overall　risk　of　construction　project　to　a　large　extent,　which　is　conducive　to　the　smooth　conduct　of　company　consulting　activities,　and　further　improving　consulting　management　level.　Based　on　correlation　theory　of　risk　management　and　whole　process　cost　management,　this　paper　analyzes　risk　closely　related　to　project　cost　from　the　perspective　of　cost　consultation　institutions.　Using　company　S　project　B　as　example,　it　uses　risk　management　methods　and　tools　such　as　analytic　hierarchy　process　to　manage　construction　project　whole　process　cost　consultation　risk,　and　on　this　basis,　puts　forward　a　series　of　countermeasures.　©　2017　American　Society　of　Civil　Engineers.
