    Earthwork is an activity of excavating, hauling and placing of materials, as well as including the measurements of figuring volumes of such materials in the field and office with the best inexpensive methods. Modern geomatic tools, such digital level, theodolite/total station, GPS and 3D laser scan, were well-known for earthwork data collection, and mainly two methods were identified for earthwork volumes competition. These technologies could effect on quality, time and cost for construction projects where these aspects are the most important points. In order to complete this research, literature review, data collection and data analysis were interrogated to ascertain the current state of practice.
    In this research, questionnaire method was used to collect information from professional companies and organisations. The results indicated that companies and organisations were used total station and GPS as their main technology to collect data for earthwork measurements. Each technology has its own accuracy, time consuming and costs required. In terms of accuracy, firms were indicated that total station has the highest accuracy in both horizontal and vertical than other technologies. Digital level and total station were cost less than other technologies in earthwork data collection processes. However, these two technologies required more man-power than other techniques, but 3D laser scan consumes less time for gathering data.
    The majority of participates were using software method to compute earthwork volumes, because this method can eliminate human errors and introduce additional check as well as software is repetitive. Land Surveying System (LSS) program was used most and Building Information Modelling (BIM) was used least. In terms of training needed, the majority of participates were provided training to their employees. They provided training as it is required to familiar their employees with new technologies and keep them up to date with new technologies.
