All About 3D Model Review: Piping Engineering

Clarify the 30% model review purpose by finalizing equipment locations, confirming operational access, and aligning plant layout with safety and hazard considerations.

explore safety check points in a 30% model review for piping projects, including egress routes, walkways, operator access to valves, crane access, safe equipment spacing, and hazard minimization.

Identify civil checkpoints at 30% model review, focusing on road layout, crane access, and road crossings, plus piping, electrical, and instrument corridors, with underground or bridge routing.

Explore mechanical 30% model review checkpoints, including equipment location and orientation, monorails and debit requirements, and space considerations for loading, unloading, and catalyst handling to ensure safe operation.

Explore 30% model review checkpoints focusing on identifying primary and secondary steel frames, pipe racks, platforms, and architectural items, ensuring safe operation, maintenance access, and blast wall considerations.

Cover 30% model review checkpoints for piping and electrical instrumentation, focusing on large bore lines, underground networks, fire water networks, routing, materials, foundations, cable routes, and substation location and volume.

60% model review marks the second milestone in the design phase, focusing on constructability and operability of steel, piping, and mechanical systems, and enabling value engineering before piping isometrics.

Assess 60% model review objectives: close 30% observations, highlight layout changes to the client, and verify safety, fire safety equipment, underground network, isometrics, and nozzle orientation for process integrity.

Identify 60% model review safety checkpoints, including safety and egress routing, escape routes, vent locations, fire hazard zones, eyewash, and firefighting access. Ensure 30% observations are closed and incorporated.

Review civil checkpoints for the 60% model, including road layout, width, safety, and crane movement. Finalize pipe rack details, non-process buildings, drainage, underground piping, and security measures before 60% review.

Outlines the structural checkpoint at 60% model review, covering steel framing, access platforms, manholes, bracings, pipe racks, and shelter accessibility, including 30% model review findings.

Finalizes 60% piping model review by freezing big bore lines, performing stress analysis, and validating critical line routing with stress reports for stakeholder approval, including instrument tappings and expansion loops.

Present 60% model review checkpoints for mechanical discipline, including major equipment locations, mechanical handling, package unit layout with vendor data, and final equipment placements for accessibility.

Review 60% model review checkpoints for electrical and instrumentation, including major equipment locations, overhead cable layouts, lighting, cable trays, junction boxes, control rooms, and instrument tapping points.

Execute the 90% model review as the final design stage, with all drawings, specifications, and vendor data ready and incorporated into the 3D model. Open points from 60% are resolved.

Ensure client and stakeholder acceptance of the 90% model before publishing construction drawings, with minimum observations, and confirm operability, accessibility, constructible feasibility, and compliance with design, codes, and project specifications.

Review final safety checkpoints for the 90% model review, including final routing, escape routes and locations, equipment positions with safety distances, flare location and hazard zones, and firefighting access.

Review civil and structural checkpoints for 90% model review, including roads, bridges, culverts, and infrastructure buildings, and present a complete 3d final model with pipe racks, footings, platforms, and trenches.

Review and verify 90% model checkpoints for piping, mechanical handling platforms, and electrical and instrumentation, ensuring all equipment, connections, supports, and underground networks are modeled, accessible, and finalized.

Prepare and maintain a master set of model review documents, including piping and instrumentation drawings, equipment and line lists, and vendor drawings, with revisions, for 30%, 60%, and 90% assessments.

Contractors notify the client and stakeholders about model review schedules, and client-side process, maintenance, operations, and project engineers attend with contractor representatives to review scope and acceptance.

Outline roles and responsibilities for 3D model review sessions, including scheduling by the project manager, document prep by the project engineer and 3D admin, and cross-discipline coordination of action items.
