This project began with the expansion plan from PTT Public Company Limited to improve Sirinart Rajini Ecosystem Learning Center's facility for the future uses.  The project involves in many design aspects such as landscape design, signage design, and some structural design to improve the facility's condition in term of public safety, structure durability, and aesthetic condition.  The major issue is that the walkway's dilapidation in the mangrove forest area require a major repair and even reconstruct in some parts due to the salty environmental condition that has caused many destructions to the walkway's structure.  Another issue is the signage's confusion from the several installation in many different times which eventually created a mixture of design language and some communication confusions for visitors.
