易于使用的解决方案，以防止公用事业事故

Waskita Karya (Persero) Tbk is one of the leading state companies in Indonesia that plays a significant role in infrastructure development. Founded in 1961, Waskita Karya initially participated in water-related project work including reclamation, dredging, ports and irrigation. However, since 1973 the company has started to develop its business as a general contractor on a broader range of construction activities including roads, bridges, airports, waste processing plants, cement plants and other industrial facilities.

The Bekasi-Cawang-Kampung Melayu Toll Road or shortly Becakayu is a motorway constructed over the Kalimalang River to decrease traffic congestion around Kalimalang. The construction of the motorway section was finished in 2018. Since then, Bekasi has started to grow rapidly and has now become an "escape" to citizens who can't afford to purchase their property in Jakarta. Besides, Bekasi has also become an important satellite city of Jakarta.

The data from BPS (Statistics Centre) from 2016, shows that there are around 359.531 commuters from Bekasi to Jakarta which increases traffic jams and makes, for example, a 15 kilometres distance take between 2-3 hours driving in peak hours. Therefore, the government initiated the construction of the Becakayu Elevated highway, which will connect Bekasi to Jakarta along 21,042 km with a total investment up to 7.2 billion IDR.

With Becakayu Elevated highway the same route will only take 30 minutes. This highway project has a vital role in accelerating traffic, as well as goods transportation and services distribution connecting the two major cities.

挑战

Waskita Karya因基础设施和高速公路的整个设计和建造而被签约。在当前的项目（Becakayu阶段2A - Edge）以及700多米的情况下，合同团队正在穿越各种地形和沥青条件。该部分由48个具有不同尺寸的支柱（基础）组成，这些支柱从5 m到10 m的深度嵌入。

It is essential to ensure in the early process that the pillar's design is correct and safe to embed up to 5 or 10 m depth. Only after this step can the construction process start.
通常，地下有很多公用事业，尤其是因为项目地点主要位于内城，并且某些公用事业非常关键，例如电缆，石油和天然气管道。这些公用事业通常被埋葬在2 m的深度以下；因此，在柱子位置的前提下，有必要在施工开始之前检查现场现场。

The reason behind this is to avoid utility strikes when doing excavation work. If the on-site check is indicating that the planned pillar's position will jeopardise the utilities, the location of the pillar's need to be re-designed and sometimes, the dimension of the pillars themselves needs to be redone.

"Due to the short timeline of the project and a complex scope-of-work, we needed a solution which could enable us to detect buried utilities easily, but precise. Quickly means here is not only easy to use and operate but also easy to analyse and get the results. We needed a solution that allows us to know the accurate position of the utilities easily and quickly and could get the documentation immediately," explains Luki Danardi, Senior Vice-President for TREK Division.

The solution

The easiness to operate the Leica DSX and the visualisation in real time with the DXplore software, detecting buried utilities became much more straightforward, and anyone could do it without the need to having ground penetrating radar (GPR) background expertise. With little training, the staff was able to use without any issues.

除此之外，该软件允许检测地下埋藏的公用事业，更快但精确。还允许将收集到的数据导出到各种文件的格式（CAD或BIM软件）上，该数据允许以后与其他部门一起使用，甚至可以直接发送到挖掘机的机器控制系统。

“ Leica DSX正在支持我们检测所有类型的埋藏公用事业，例如水管（PDAM），光纤电缆以及油气管道，并具有高分辨率。因此，我们可以避免在施工期间避免使用公用事业的风险，节省效用的风险美国时间并避免该项目的额外费用。减少在挖掘工作期间的公用事业罢工，并减轻由于作品失败造成的罚款而减轻金钱的损失，” Danardi解释说。

The outcome

“我们可以在项目中检测到埋藏的公用事业，因此由于发掘的失败，它可以减轻施工期间的事故和薪水。与我们使用的旧方法进行比较；从旧方法进行比较；从时间节省到节省成本为节省成本并为基础设施项目提供准确的设计," Danardi explains.

除了节省成本和时间外，检测解决方案易于使用，并且学习曲线非常低。由于Leica DSX的逻辑和用户友好的界面，Waskita Karya只需要一日培训，这是由Leica Geosystems团队进行的。

"Start from that day; our internal team have been able to operate the GPR correctly. They could even teach their colleagues to use the system,"concludes Danardi.
