🌊 Bali Beach Conservation Project Overview

This paragraph introduces the Bali Beach Conservation Project, outlining its importance to the tourist industry in Bali and the spiritual significance of beaches for the Balinese Hindu population. It mentions the project's division into four packages located at Sanur, Nusa Dua, Tanah Lot, and Kuta Beach, with the first package centered around addressing severe erosion along the coastline of Sanur Beach. Financial backing is provided by the JBIC, and construction is managed by Penta Was Kita. The project involves building groins to protect the beaches from erosion.

05:00

🚧 Construction and Material Transportation for Groins

This section details the construction process for the groins, specifically focusing on the transportation and installation of materials such as limestone armor. It describes the use of barges, dump trucks, excavators, and other heavy machinery to carry out the work. The construction at different groin sites is progressing, with elevations being checked to ensure compliance with design specifications. Additionally, it mentions the extension of existing drainage outlets and careful monitoring during the installation to meet the technical requirements.

10:13

🌿 Landscaping and Additional Infrastructure Works

The focus of this paragraph is on landscaping work, which includes the construction of gazebos using oak wood, walkways, and parking lots. The concrete paving and tiling processes are described, along with the installation of stainless steel barriers to prevent motorbikes from entering pedestrian areas. It also mentions additional work such as the construction of a bridge to connect Pangombak Temple with the Murthasari region, ensuring structural integrity through concrete tests and meeting technical specifications.

15:17

🌊 Environmental Monitoring and Safety Measures

This section highlights the environmental aspects of the project, including coral and fish reef monitoring, which is done by experienced divers to assess the impact of the construction on marine life. Additionally, seawater contamination is monitored using turbidity devices, and work is paused if contamination exceeds acceptable levels. The air quality and noise levels are also checked, ensuring minimal disruption to the environment. The paragraph concludes with the emphasis on social outreach and safety patrols to reduce social impact and maintain workplace safety.

20:21

🏖️ Beach Filling and Sand Dredging Process

This paragraph provides details about the beach nourishment process, which involves the collection of sand using seismic methods and dredgers. Heavy equipment is used to transport and distribute the sand, ensuring it meets design specifications. The process involves assembling pipes, using booster pumps, and dredging sand from borrow areas. The sand is then transported to temporary walls before being spread over the beach using dump trucks and other machinery.

25:21

🏗️ Final Construction and Project Completion
