Advantages of using GIS

Geographic Information Systems offer numerous advantages in civil engineering and construction projects, revolutionising how this industry approaches planning and execution.

GIS allows civil engineers and construction professionals to visualise complex geospatial data on interactive maps and 3D models. GIS also enables the integration of various data layers, such as topography, land use, infrastructure, and environmental information. It makes identifying potential challenges and opportunities between different site elements, including infrastructure, utilities, and land features easier.

GIS supports a project’s potential environmental impact, which enables conscious decision-making for risk prediction and sustainable planning. The software analyses the environmental risks using real-time data, such as air pollution, flooding, soil erosion, and other natural disaster causes in the early stages of a civil infrastructure project. It also identifies environmentally sensitive areas such as wildlife habitats, protected zones and wetlands. Civil Engineers can then develop appropriate strategies to minimise disturbance, reduce negative environmental outcomes and foster sustainable practices.

GIS is cost-effective as it considers the factors to identify suitable sites during the planning and design process. This ensures optimal site selection and reduces the risks of unforeseen circumstances during the construction phase. By analysing spatial data, GIS helps optimise resource allocation, such as labour, materials, and equipment costs. For existing infrastructure, GIS assists in asset management, identifying areas requiring maintenance, and tracking maintenance schedules, ultimately leading to cost-effective maintenance strategies.

GIS enables data integration from various sources and organises the information, making the whole process understandable for users. This promotes better communication and collaboration amongst project stakeholders, leading to more efficient project execution.

Henceforth, GIS empowers civil engineers with valuable insights and tools to optimise project outcomes, make well-informed decisions and enhance sustainability.
