(1) Mechanical and electrical engineering for highways is considered a supporting discipline within highway engineering. Its construction progress and quality control are often influenced and constrained by other trades. Most mechanical and electrical installations coexist alongside other professional works.
Using design documentation as a foundation, while ensuring the construction quality, safety, and progress targets for mechanical and electrical engineering are met, construction organization plans or specialized construction proposals prepared by other project participants are reviewed. This process addresses the “incompatibility” issues that arise between different trades—for example, when equipment installation teams propose incorrect reserved or embedded dimensions or locations for building construction teams, or when pipeline installation groups conflict with steel structure teams installing work platforms in the same area. BIM technology helps optimize solutions for these clashes by coordinating workflows, generating clash coordination data, and keeping records for future reference.
(2) It is possible to simulate specific mechanical and electrical engineering plans, such as the fire alarm response in highway tunnels after an incident. This includes simulating the operation mode of the tunnel fans, alarm linkage prompts, lane indicator statuses, video linkage modes, alarm point switching in the monitoring hall, system-generated prompts based on real-time site conditions, and warnings for vehicles that have not yet entered the tunnel. Guided by a human-centered approach, these simulations offer an immersive, three-dimensional experience of preset escape routes and detailed evacuation plans through vehicle and pedestrian pathways within the 3D space.
(3) Time-based simulations of mechanical and electrical engineering construction phases verify whether the construction organizational design aligns with the scheduling requirements set by each discipline and meets the project’s overall expectations. Dynamic scheduling and resource management techniques are applied to plan construction activities, adjust strategies as needed, and optimize the overall construction approach.
