Service Overview
Steel plant construction and modernization projects often must be executed while the plant continues to operate requiring meticulous coordination between construction crews, plant operations, and maintenance teams. A crane outage window of 48 hours for a tie-in may be the only opportunity in a quarterly production cycle. Desapex’s 4D planning tools bring visual, spatial intelligence to these high-stakes scheduling challenges.
Our Digital-First Approach
Link Activities to 3D Models
We link every construction activity to its corresponding 3D model element, creating animated construction sequences.
Core Deliverables
4D erection sequencing for heavy steel structures showing column erection order, crane girder installation, and wall cladding sequences.
Shutdown planning visualization identifying operating/construction zone boundaries, isolation requirements, and safety exclusion zones.
Heavy lift planning with crane reach analysis, rigging studies, and ground bearing pressure assessment.
Progress monitoring through periodic laser scanning compared against the 4D schedule.
Why Choose Desapex
A missed tie-in window in a steel plant modernization project can delay commissioning by an entire production cycle often 3-6 months. Desapex’s 4D shutdown planning gives planners and operations teams a shared visual understanding of exactly what needs to happen, in what sequence, within each outage window eliminating the ambiguity that leads to overruns and extended shutdowns.
Unique Selling Proposition
Our USP is that Desapex’s 4D models are not just presentation tools; they are working project management instruments that are updated weekly from actual progress data, providing continuous earned value tracking in a format that engineers, managers, and operations teams can all understand intuitively.
