Introduction

Overview

It is estimated that approximately 75% of all park signs fall into the Visitor Information (VIS) category. VIS Signs are designed to present information in a consistent, attractive, convenient, and flexible format. Such information may involve pedestrian or bicycle and (low–speed) motorist guidance, regulations, resource protection, instructions and general information, fee information, safety warnings, maps, and interpretation. VIS Signs may also be used to identify parks (or park areas, features, or facilities) when more monumental identification signs are not required.

The flexible system of post and frame hardware components may be configured in a variety of ways to hold modular sign panels and other accessories. VIS hardware is available in a range of durable materials to suit local conditions, all selected for vandal resistance, low maintenance, and long life–cycle performance.

Sign frames are designed to hold graphic panels made from a variety of materials including porcelain enamel, fiberglass embedment, polycarbonate embedment, high pressure laminate, digitally printed adhesive vinyl on aluminum substrates with protective overlaminates, or computer cut retro–reflective sheeting.

Besides supporting sign panels, VIS hardware is designed to accommodate a number of accessories including bulletin cases, brochure holders, and posting displays.

This manual provides details and information on the specification and fabrication of VIS hardware.

Signs are the most frequently used means of communicating with park visitors. The National Park Service UniGuide Sign Standards provide design and fabrication guidelines for a full range of park signs including Park Identity, Motorist Guidance and Visitor Information (VIS).

VIS System Overview

Overview

The VIS system consists of a welded frame and core panel that can be attached to posts to create

Low Profile wayside bases, Upright Sign Bases, or for Wall Mount displays. The system consists of an aluminum extrusion or a break–formed steel frame with an internal structural core panel. Sign frames are designed to capture the graphic panel on four sides and includes a secure, but removable, capture rail for ease in changing panels.

Accessories that can be attached to upright bases include bulletin cases, brochure holders, and miscellaneous post displays.

Overview

The chart to the right provides an overview of the base hardware available in the VIS system.

All VIS bases are available in a variety of material options including weathering steel, galvanized steel, and painted aluminum. Painted aluminum bases are available in three paint color finishes.

The material and finish appropriate for a specific base depends primarily on the sign’s purpose and its location. Weathering steel is an excellent choice for low maintenance in many forested and desert sites; galvanized steel is very durable in coastal and other salt–water and corosive environments; and painted aluminum may be a good choice for an urban environment.

Low to the ground, Trailsides are an excellent choice for plant ID markers, site markers, trail guides, and anywhere a small discreet sign is required.

Designed to stand vertically so they attract attention, Upright bases typically provide practical information to visitors rather than site–specific interpretation.

Like the Low Profile base, Upright bases are available in a variety of material finishes and sizes. Bases can be fabricated as a single unit, double or triple inline unit, and tri-sided and four–sided units. The single unit and inline bases can be configured for one or two-sided display. All of the uprights, (in certain preset sizes) are available with or without a roof structure.

Each base is designed to hold panels or other accessories including bulletin cases.

The Low Profile base is the preferred style for NPS interpretive outdoor exhibits. Available in a variety of material finishes and sizes the base’s simple, unadorned form makes it appropriate for any park landscape.

Wall Mount frames are designed to display information on vertical surfaces. Frames are available in a variety of materials and sizes.

VIS Hardware Base Material Options

Overview

Weathering steel is an excellent material option for many NPS sites. Over time, with exposure to the elements, the bases turn a golden brown.

The bases are virtually mainternance free and do not require painting once installed.

Weathering steel bases can last well over 15 years.

Bases shipped are not pre weathered. When they arrive the bases are black and begin the weathering process when exposed to the elements.

Aluminum bases are a good all around choice for many NPS sites. Aluminum bases are primed and painted.

The bases are not maintenance free and do require occasional field cleaning and touch up to keep them looking good.

Aluminum bases are available in three standard paint colors.

All bases are painted with a coarse spatter coat finish for added durability.

Galvanized steel is an excellent choice for saltwater and other marine sites. Prior to final fabrication the base legs and frame are hot dipped galvanized which imparts a protective finish to the steel.

The bases are virtually mainternance free, show little if any sign of rust inhibition, and do not require painting once installed.

Galvanized steel bases can last well over 15 years.

When they arrive the bases have a shiny silver finish. Over time the bases patina to a dull grey.

VIS Hardware Mounting Options

Overview

The chart to the right provides a basic overview of the hardware installation options available in the VIS system.

Refer to the fabrication details for more information.

Direct embedment is the typical mounting method for all VIS hardware. Post depth is typically 30" to 36" and posts are secured with concrete.

Stabilizer fins are another mounting accessory for direct embedment. Plates are attached to each base leg. The fins allow installation of the base without the use of concrete.

Socket mounting allows the VIS base to be removed. Oversized sleeves are secured in the ground and the base can slide in and out. This is an excellent choice for park areas with huge snowfall or flood conditions.

Wall mounted bases use a modified baseplate that facilitates installation on low walls.

Baseplate mounting allows installation where a deep footer is not practical. The base features a welded baseplate that attaches to imbeded j-bolts or all-thread rods.

Stabilizer bars are a mounting accessory for direct embedment. The bars are welded to each base leg and prevent racking due to loose and shifting soil. This is a good choice for seashore conditions.

The sled base allows the frame and post to be free standing. For security the base can be mounted with threaded rods.

Deck mount hardware uses a baseplate and anchors to install the base on wooden decks and walkways. Deck mounts are typically custom and site specific.

VIS graphic panels are designed to provide an attractive and consistent way to present a broad range of messages.

This includes park and facility identity, park regulations, safety warnings, information, interpretation, pedestrian guidance, low speed motorist guidance, and other wayfinding information including maps. The modular grids and design standards of VIS signs allows presentation of content in discrete, easily comprehended “eyefuls” which aids in visitor comprehension and retention of information.

Please refer to the Visitor Information System, Panel

Specification Manual for more information.

VIS Panels

Panels may be produced in porcelain enamel, high pressure laminate, fused polycarbonate, fiberglass embedment, digitally printed adhesive vinyl, or computer cut retro–reflective sheeting.

Selection of material is based on life-cycle cost, budget, exposure to wear, and need for retro–reflective legends if viewed from an auto-mobile. Production methods include digital printing, screen printing, and adhesive–backed computer–cut vinyl.

VIS Hardware Assembly Codes

Overview

Although the VIS is a system of simple components, material choices, panel sizes, and mounting options offer a multitude of fabrication options. In order to adequately describe a base and its attributes a code system has been created to aid in specification of base hardware.

The code system provides the information necessary to describe the base, its size, mounting, and other options for fabrication. A sample specification code might look like this:

UP_24x36_WS_DE_PF_BC The code breaks down as follows:

UP

This is the frame type. UP is the specification code for an upright base.

24x36 This is nominal frame size or bulletin case size. In this case a 24 x 36 bulletin case mounts to the base.

WS

This is the material type. This frame will be made from weathering steel.

DE

This is the mounting type. This frame will be a direct embed.

PF

This is the mounting accessory. This frame posts will have post fins for inground stabilization.

BC

This is the base accessory. In this case the base will have a bulletin case instead of a panel.

How to Specify a VIS Base

With the code system it is easy to specify the base type.

For this exercise it is assumed all the decisions about the base have been made including the size, panel content, material mounting, and location.

Use the Code Charts on the page 16 to specify your base.

Step 1. Choose Base Type

From the VIS Hardware Assembly Chart choose the correct assembly code. If necessary refer to the VIS Hardware

Assembly Descriptions on page 7.

Step 2. Choose Nominal Panel Size

If necessary refer to Panel Size Charts, beginning page 11.

Step 3. Choose Base Material

Weathering steel, galvanized steel, or painted aluminum.

Step 4. Choose Mounting Method

Step 5. Choose Mounting Accessory (If Required)

Step 6. Choose Base Accessory

This could be a bulletin case, brochure dispenser, or roof structure for a tri or quad upright.

Step 7. Additional Notes

Here you would indicate additional information for the fabricator including custom requests or modifications and colors.

Section I: Trail Side Series

Small and simply formed, NPS “trailside” exhibits bases offer an unobtrusive way to provide brief interpretive message or important safety information with minimal impact on the landscape. Trailsides are available in weathering steel, galvanized steel, or painted aluminum and can accommodate several types of graphic panels, attached with stainless steel barrel nuts as shown on page 58. The final assembly is mounted by direct embedment into the ground. The angled tab at the bottom of the base prevents uplift and removal once the base is installed.

Low Profile Series Overview (LP)

Section III: Low Profile Series December 1, 2008

NPS “low–profile” wayside exhibit bases are designed to diminish their presence on the landscape by using the least material required to securely hold an exhibit panel. Panels are positioned at a 45–degree angle to permit visitors a clear view of the feature that the exhibit interprets. Bases are available in three materials, appropriate to a variety of landscapes: weathering steel for forested or desert environments; galvanized steel for coastal zones; and painted aluminum (in three standard colors) for urban areas. The first two materials require little maintenance.

The legs of most wayside bases are directly embedded into the ground, although other mounting methods are available to accommodate site conditions. As illustrated on the following pages, NPS waysides bases come in a wide range of panel sizes which are held within a full-frame assembly.

The top frame member is secured by a replaceable set screw which can be easily removed to allow panel replacement.

General Requirements

Section VII: Specifications

Frames

The VIS System includes a fabricated panel capture frame with a removable top rail cap and a structural core panel.

The frame is designed to contain and capture the graphic panel on four sides. Frames can be configured for one or two-sided display.

Frames fabricated in aluminum utilize an NPS standard

“F” extrusion welded to a solid sheet aluminum core panel for structural rigidity. The frame features a removable top extrusion secured with tamper proof hardware to allow installation and removal of graphic panels.

Two-sided frames utilize a break-formed channel system with floating internal core panels for structural rigidity.

The top channel is removable and secured with tamper proof hardware.

Frames fabricated from steel (including one and two–sided structures in weathering and galvanized material) utilize a break–formed channel system with floating internal core panels for structural rigidity.

Posts

The VIS system features aluminum and steel tubular posts.

Posts material for upright and low profile bases includes tubular aluminum and carbon steel in 2" x 2", 2" x 3" sizes, and 1/2" x 2" bar stock. Carbon steel can be galvanized for marine environments.

Panels

Sign panels are inserted into the frame in front of the core panel. The sign frames accommodate a variety of graphic panel types including porcelain enamel, fiberglass embedment, polycarbonate embedment, high pressure laminate, digitally printed adhesive vinyl on aluminum with protective overlaminates, or computer cut retro–reflective sheeting on aluminum. The frame system can accommodate panel thicknesses from .090 up to .125.

Signs and sign assemblies shall be manufactured using materials and fabrication processes as described in these specifications and in the companion technical drawings.

The Visitor Information System (VIS) consists of a standard group of post–and–frame components and accessories that are fabricated from aluminum or steel and mechanically assembled. Refer to the VIS Sign Fabrication Drawings for specific details and fabrication guidelines.

National Park Service | U.S. Department of the Interior | NPS UniGuide Program Visitor Information Sign System | VIS and Wayside Hardware Specification Manual 180Revision 3 October 5, 2017Section VII: Specifications

Dimensions

Inch dimensions are used for legend size and all related dimensions including layout grids, panel sizes, post lengths, mounting height, and post drilling for connection of panel to post. All hardware, machine parts (cast caps, mechanical fasteners, connection details), and materials (tube, dimensional lumber) are specified in inches. Dimension for assemblia and panels are listed by length x width.

Note: Panel dimensions described in this manual are nominal. Nominal sizes are used for ease of specification.

Fabricated panels shall be undercut by 1/16" on each side. For example a specified, nominal 24" x 36" panel, shall be fabricated to a finished size of 23–7/8" x 35–7/8".

Frames shall be fabricated to allow an expansion tolerance of

1/16" on all sides. The outer dimensions of the frame and core panel assembles shall be 1/2" larger than the specified nominal size. For example a nominal 36" x 24" assembly shall be frabricated to an outer dimension of 36 1/2" x 24 1/2".

This leaves 1/8" of expansion on all four sides.

Hardware

The contractor shall provide all hardware, including screws, rivets, wej-it studs, threaded roads and j-bolts as required to fully assemble and install each base or assembly structure.

Material Options and Substitutions

All materials shall be new and of first quality. Materials shall meet or exceed the standards and specifications herein or by reference. All materials and fabrication methodology shall comply with this specification or be an “approved equal”.

A limited number of materials have been specified by manufacturer’s trade name. These products are specified as examples and not to limit use of alternative products and suppliers that are of equal or superior quality.

Function

These specifications are provided as a guideline for the fabrication, assembly, and installation of VIS signs for the

UniGuide Program of the National Park Service. Material and fabrication specifications are provided for each structure.

All signs shall be fabricated to the specifications described in this chapter. Additional instructions and requirements including modifications to structures and details shall be provided within individual contracts that describe the performance of specific sign fabricators and suppliers.

Sign Identification Codes

Signs within the VIS system are identified by a series of reference code numbers that indicate the type of sign, sign panel/frame size, material mounting type, mounting accessory, and accessory. Refer to the Overview section of this manual for a description of the VIS Code System.

Reference Standards

American Society for Testing and Materials standard specification for Aluminum and Aluminum Alloy Sheet and

Quality of Materials

All materials shall be new and of first quality. Materials shall meet or exceed the standards and specifications herein or by reference. Factory seconds shall not be accepted. All materials shall comply with this specification or approved equal.

Engineering

The following criteria have been used as the standards governing material specifications, assemblies and footings for all NPS VIS signs unless otherwise specified or engineered.

Wind Pressure : 20 PSF ***

Soil: 1-TSF (2 KSF)-Minimum * **

Frost Depth : 36" Maximum unless otherwise noted

Concrete: 3000 PSI. / 28 days

* For all direct embedment footings, backfill in 6" lifts tamped to 95% compaction.

** Subgrade materials are assumed to be organic free sand/ gravel/silt, or mixture of same, with bearing capacity of
