Main features of the project are to construct the following structures and facilities.

NSA designs the mechanical, electrical and plumbing services including the consortium designs for two facility buildings of the premises. The design scope includes the electrical systems, ELV Systems, fire protection system, fuel supply system and water & wastewater disposal system. Addition to above, internal road network and the reclaimed land portion are to be properly designed by NSA.

NSA design team is collaboratively working with Paaras Marine Solutions Pte. Ltd. designer of structural elements of the Quay to facilitate the MEP elements such as cable & pipe duct, high mass poles, fuel dispensers and electrical & ELV control room. All the structures that facilitate the MEP systems including water tanks, fuel storage tanks, wastewater treatment plants and sea outfall are designed by the architectural and structural design team of the NSA.

The value engineering specialists and contractual specialists of NSA are the key advisors to the design and build JV contractor on contract administration and negotiations with the client and the consultant. The contractual advisory service of NSA has benefited the JV Contractor to manage the project in the current dynamic macro environment of Sri Lanka Construction industry.
