Convention Center Partition Track Escalator Adjacency Drawin

When planning a convention center, the convention center partition track escalator adjacency drawings are among the most critical documents you will produce. These drawings define how movable wall panels will operate in a challenging environment where floor levels change and public circulation is constant. The track layout must account for the escalator’s presence, ensuring that panels can move smoothly from a parked position to a closed partition without interference. This article explains what drawings you need, what details they must include, and how to communicate requirements to manufacturers and installers.

Movable partition track drawings must show clearances and stacking routes adjacent to escalators.

Why Escalator Adjacencies Demand Special Attention

Escalators introduce vertical circulation that complicates the horizontal plane of a movable partition. The track system must cross the opening without a floor track, using an overhead suspension. This means the ceiling structure above the escalator must support the track and allow panels to travel without obstruction. Additionally, the stacking area must be planned to avoid conflicts with escalator traffic and emergency egress routes.

Structural Interface Between Track and Building

The drawings must show the exact location of the top track relative to the escalator’s structural elements. This includes the trusses, beams, and hangers that support the escalator. The partition track may need to be integrated into the same support system or be independent, depending on the building design. Clear sections and elevations are necessary to illustrate how the track is anchored and how it avoids the escalator’s moving parts.

Clearance and Safety Zones

Local codes often require specific clearances around escalators for safety. Your drawings must indicate these zones and show that the partition track and panels do not encroach upon them. This includes headroom clearances, side clearances, and the area where passengers step on and off the escalator. The stacking position must be placed outside these zones to prevent accidents.

Essential Drawings for the Track Layout

To ensure a successful installation, you need a comprehensive set of drawings that cover all aspects of the track system. These include floor plans, reflected ceiling plans, elevations, and sections. Each drawing serves a specific purpose and must be coordinated with other building systems.

Floor Plans: Showing the Opening and Stacking Area

The floor plan is the primary document that shows the overall layout. It must indicate the opening that the partition will close, the path of the track, and the stacking area where panels park. For escalator adjacencies, the floor plan should also show the escalator’s location, its direction of travel, and any surrounding columns or walls that could affect the track route. The stacking area must be a straight or turning route that is clearly dimensioned and annotated.

Reflected Ceiling Plans: The Overhead Track Route

Since the track is suspended from the ceiling, a reflected ceiling plan (RCP) is essential. This drawing shows the ceiling grid, lighting, HVAC, and other overhead services. The track route must be coordinated with these elements to avoid clashes. The RCP should indicate the track’s height, the suspension points, and the path of the panels as they move from the stacking area to the closed position. For escalator adjacencies, the RCP must show how the track crosses above the escalator, including any changes in elevation.

Elevations and Sections: Vertical Clearances

Elevations and sections provide a vertical view of the partition and track. They are critical for understanding the relationship between the track, the panels, and the escalator. Sections through the escalator and track show the vertical clearances, the position of the track relative to the escalator’s handrails, and the space required for panel suspension. Elevations of the partition in the closed position show the panel heights and any pass-doors or glazing.

Detailing the Track Route: Straight, Turning, and Stacking

The track route is not always a straight line. In convention centers, partitions often need to turn corners or follow curved paths to reach a stacking area. Your drawings must clearly define these routes, including the radii of curves and the angles of turns. The stacking area itself must be planned to accommodate the number of panels without exceeding the available space.

Straight Routes and Their Documentation

For straight routes, the drawings must show the track length, the spacing of suspension points, and the clearances at each end. The track must be level and aligned with the opening. In the case of an escalator adjacency, a straight route might run parallel to the escalator, requiring careful coordination of the track’s height to avoid the escalator’s balustrade.

Turning Routes: Curves and Switches

Turning routes require special track components, such as curves and switches. The drawings must specify the radius of the curve and the location of switches. These components must be shown in plan and section, with dimensions that allow the panels to navigate the turn without derailing. For escalator adjacencies, turning routes must be placed away from the escalator’s entry and exit points to avoid congestion.

Stacking Positions: Parked Panels

The stacking position is where panels are stored when not in use. This area must be designed to hold all panels in a compact configuration, often in a zigzag or straight line. The drawings must show the stacking area’s dimensions and the sequence of panel movement. In a convention center, the stacking area might be beside the escalator, so the drawings must ensure that parked panels do not block emergency exits or fire-fighting equipment.

Pass-Doors and Emergency Egress

Movable partitions often include pass-doors to allow pedestrian traffic when the partition is closed. In a convention center, these doors must comply with egress codes, especially when the partition creates a large room. The drawings must show the location of pass-doors, their swing direction, and the hardware used. For escalator adjacencies, pass-doors should be placed away from the escalator to avoid crowding.

Integrating Pass-Doors into the Track System

Pass-doors are integrated into the partition panels, and their operation must be coordinated with the track. The drawings must show how the pass-door panel is supported and how it seals when closed. The pass-door must also be able to move with the panel when the partition is being stored. This requires careful detailing of the track at the pass-door location.

Egress Routes and Signage

Your drawings must also indicate the egress routes and any signage required by local codes. The partition should not impede the path to exits, and the stacking area must not block exit doors. The drawings should show the relationship between the partition and the escalator’s emergency exit routes, ensuring that the partition can be moved quickly in case of an emergency.

Acoustic Sealing and Performance Documentation

While acoustic performance is not directly tied to the track drawings, the sealing details are crucial for achieving the desired sound insulation. The drawings must show the perimeter seals, the bottom seal, and the vertical seals between panels. For escalator adjacencies, the gap between the partition and the escalator structure must be sealed to prevent sound leakage.

Perimeter Seals and Their Drawings

Perimeter seals are installed along the top, bottom, and sides of the partition. The drawings must indicate the type of seal and its location. For example, a top seal might be a drop seal that lowers onto the floor when the partition is closed. The drawings must show how the seal is activated and how it compresses to create a tight fit.

Acoustic Concepts: STC and Rw

STC (Sound Transmission Class) and Rw (Weighted Sound Reduction Index) are metrics used to rate the sound insulation of a partition. While we do not provide specific values, it is important to understand these concepts when specifying a partition. STC and Rw are determined by laboratory tests and field measurements, and they depend on the panel construction, seals, and installation quality. Your drawings should note the target acoustic performance, but the actual values must be confirmed with the manufacturer based on project-specific requirements.

Coordinating with Other Building Systems

In a convention center, the partition track must be coordinated with mechanical, electrical, and plumbing (MEP) systems. The drawings must show how the track avoids ductwork, sprinklers, and lighting fixtures. This coordination is especially important near escalators, where the ceiling space is often congested with escalator machinery and ventilation.

MEP Clash Detection

Use building information modeling (BIM) to detect clashes between the track and MEP systems. The drawings should include a clash detection report that identifies and resolves conflicts. For escalator adjacencies, pay special attention to the escalator’s motor room and any exhaust ducts that might be in the same area as the track.

Lighting and Ceiling Integration

The track may need to be integrated with the ceiling design, including lighting fixtures and acoustic panels. The drawings must show how the track is suspended and how it interacts with the ceiling grid. In the stacking area, the ceiling might need to be recessed to accommodate the panels, and the drawings must detail this condition.

Documentation for Procurement and Installation

The drawings are not just for construction; they are also essential for procurement. They allow you to obtain accurate quotes from manufacturers and ensure that the specified system meets your needs. The drawings should be accompanied by a written specification that describes the performance requirements, finish options, and installation procedures.

Finish Options and Aesthetics

EBUNGE offers a variety of finishes, including laminate, melamine, fabric, leather, glass, and other approved surfaces. The drawings should indicate the finish for each panel, but the final selection can be made during procurement. The finish does not affect the track layout, but it is important for the overall design.

Project Documentation and Approvals

Ensure that all drawings are reviewed and approved by the relevant authorities, including the building department and the owner’s representative. The drawings should be stamped by a licensed professional and include all necessary details for permit approval. For escalator adjacencies, the drawings must also be reviewed by the escalator manufacturer to ensure no interference.
