For LNG projects with land reclamation under deep sea conditions,enclosure and revetment are usually implemented first,then reclamation and foundation treatment are used to form land area,and finally the prefabricated structure of intake is excavated and embedded.This construction process has resulted in long construction period,high cost,no environmental protection and other issues.The integrated design and construction of intake and revetment engineering are realized through BIM collaborative design,early determination of functional parameters of intake and reasonable adjustment of construction process.The integrated design and construction not only guarantees the quality,safety,environmental protection and progress,but also achieves good economic and social benefits,which can provide reference for similar projects in the future.
