Based in Korat, Thailand, Khunnon Construction, a subsidiary of S.P.T Construction, focuses on superhighways, road and bridge constructions. These projects require precise accuracy. With that in mind, Khunnon Construction purchased the Satlab Geosolutions SLC multi-purpose GNSS receiver after being appointed as the main contractor for the Bang Pa-in-Nakhon Ratchasima motorway in Sector 38, a 10km section of motorway that will be completed by the end of 2019. The 196km Bang Pa-in-Nakhon Ratchasima motorway project aims to alleviate the traffic congestion on Mittraphap Road, between Saraburi and Nakhon Ratchasima.
The SLC multi-purpose GNSS receiver is a survey-grade piece of equipment with the centimetre accuracy that is required in construction works. Time and cost pressures have made it necessary for the team to invest in more productive equipment in order to be more efficient on site. Khunnon Construction chose the SLC as it is easy to use without requiring more manpower; only one user is needed to collect the data on site.
传统上，他们必须使用全站仪来调查路面，并通过自动水平交叉参考道路水平，以绘制切割和填充区域。这将需要全职验船师在现场进行，并且由于测量团队必须在待机状态下确认道路建设期间的路地。
One of the key stages of this project is to do a quick road direction survey of the slope of the road to plot out the areas for filing and cutting. Khunnon Construction is required to correct the road direction, road level and the road width, all of which can be achieved using the SLC.
KHUNNON施工，SLC的设置快速准确地完成。首先，他们设置Satlab SLX-1ng Multi-Application GNSS基站，以找到与SLC的固定定位以校准到网站。一旦校准，SLC天线就安装在车辆的屋顶上。它与平板电脑无缝连接，以提供n，e，z和三角形不规则网络（锡）模型的实时数据值。为了进一步交叉检查，SL600 GNSS接收器检查道路的定位边缘以确保其一致性。然后将道路图纸上传到软件中，以便与实际水平轻松比较，以绘制切割和填充的区域。
Products used:
SLC Multi-purpose GNSS Receiver
• Installed in the project manager’s truck for daily monitoring and cross-checking of the road construction progress
Satlab SL600 GNSS RTK Receiver
• Correct project area (boundary)
• Bridge positioning in project area
• Plotting the edge and boundaries from start to finish
“This project required a solution that was user-friendly and easy to learn. The best part is that the SLC could connect with any device preferred by the team,” said Mr Surawut Wirohtjanapirom, president of Khunnon Construction.
Through quantifying the productivity improvements, using the Satlab Geosolutions SLC multi-purpose GNSS receiver has saved Khunnon Construction 31-42% of the time previously needed and ultimately reduced the manpower required on the project to survey and cross-check the findings. The SLC’s portability and intuitive user interface allows the operator to connect with a preferred device such as any smartphone to start collecting data. After a quick tutorial on using the SLC, Khunnon Construction can immediately start the project with precision and accuracy.
