Site Visit for Third Year Civil Engineering Students

A site visit was organized for the Third Year Civil Engineering students of Don Bosco College of Engineering on 23rd April 2026, with the objective of providing practical exposure to construction techniques and project management practices.

The first visit was to ACE Infrastructure at Guirim, where students studied the construction of a raft (mat) foundation. This type of foundation was adopted due to weak soil conditions, requiring uniform distribution of structural loads. At the site, students observed reinforcement detailing, including appropriate bar spacing, tying techniques, and the placement of cover blocks to ensure adequate concrete cover. The site engineer explained the importance of raft foundations in minimizing differential settlement and enhancing structural stability. Additionally, students were guided on interpreting structural drawings, helping them understand the relationship between design and on-site execution.

The second visit was conducted at the base camp of RRSM Infrastructure Pvt. Ltd. for the Goa–Vedanta SESA road project. This visit provided valuable insights into large-scale road construction and project management. The base camp functioned as a central hub for planning, coordination, and execution, comprising material storage areas, machinery yards, batching plants, and administrative offices.

Students were introduced to various stages of road construction, including earthwork, subgrade preparation, laying of sub-base and base courses, and pavement construction. They also observed the operation of heavy machinery such as graders, rollers, excavators, and asphalt equipment. Emphasis was placed on quality control measures, including laboratory testing of soil, aggregates, and bituminous materials, along with discussions on safety practices, workforce management, and logistics planning.

A key highlight of the visit was the precast concrete yard at the base camp, where structural elements used in road and bridge construction are manufactured. Students learned about the functioning of a gantry crane used for lifting and transporting heavy components such as girders and deck segments. The role of support structures and staging platforms in ensuring stability during casting and curing was also explained. The advantages of precast construction technology were highlighted, including improved construction speed, enhanced quality control, reduced material wastage, and increased efficiency.

In conclusion, the site visits provided valuable practical exposure by bridging theoretical knowledge with real-world applications. The visit to ACE Infrastructure strengthened students’ understanding of foundation engineering, while the visit to RRSM Infrastructure offered comprehensive insights into road construction and project management. Overall, the experience significantly contributed to the technical knowledge and professional development of the students.
