PORT INTRODUCTION

This is a 24/7 Port. There are few, if any, commuters during working rush hours. POV traffic is mostly general and vacation type. Typical POV volumes are 800 - 1600 POV’s per day during the winter months and 1000-3500 POVs during peak travel season. Peak traffic occurs during the summer months, Memorial day to Labor day, and wait times during high volume periods can exceed 2 hours. NEXUS traffic is diverted to Cargo lane on high traffic periods to include holiday weekends.

Typically there is only one lane open during the midnight shift. Canada is enlarging the highway feeding into this LPOE with expectations that more traffic will use this route, which connects Montreal to Boston.

POV lane numbering starts on the west side of the main building up to Lane 5. There are (5) POV lanes (Lane 5 being NEXUS Lane during specified hours), (1) Cargo (not high/low) to the west, also used as Nexus Diversion from the usual route in Lane 5, and (1) independent bus lane to the east. Buses unload into the processing area, and bus traffic ranges from 8 to 35 buses a day. Traffic maneuvering is a challenge particularly with RVs, therefore the preferred lane for diverting higher volumes of RV’s is the Cargo lane, which offers more maneuvering room.

There is an existing Gantry supporting static advance warning signage roughly half-way between the border and Primary. The Port currently uses temporary roll-out sign for holidays. Future plans are for a Vermont DOT bypass lane to the west.

SITE VISIT OBSERVATIONS - GENERAL

This Port was part of Trip 1 for our team and was the 3rd Phase III Port we visited. We visited this site on September 10, 2014.

The main building is a two-story building above grade. The team measured an underside of primary canopy clearance of 17’-6”, which is above standard of 16’-6”. Because of its architecture, signage is unlikely to be installed on the canopy. In addition, drawings photographed on site show a different edge condition on the canopy than the as-built drawings. Because of the roadway curve immediately in front of the Primary, sight lines are a critical issue. A new gantry will be supported on concrete foundations and will require a geotechnical report and information on existing underground utilities.

ARCHITECTURAL NARRATIVE

Primary Canopy Architecture

Constructed in 1998, the primary canopy is a light curved form, detached from the Head House and Commercial buildings, that is a unifying feature of the Port. The construction consists of sloped steel pipes, wide flange and flat metal deck structure with raised seam metal soffit. Lightness is achieved through a slight upward curve to the north and south and a fine roof edge. It appears that connectiviity is difficult within the canopy given the presence of surface mounted conduit that is further covered with netting for bird protection. Installation of the LED Signage on the canopy, in the A/E team’s opinion, would likely compromise its architectural integrity. In addition the booths stop well short of the underside of the canopy so there is not much opportunity to install the signage on the booths themselves.

SIGNAGE

Approach

The inbound road utilizes two driving lanes at the international border 950 ft from the inspection canopy. The right lane starts to divide into two lanes 780 ft from the inspection canopy. A gantry with three lane signs is located 550 ft from the inspection canopy. The signs on this gantry provide direction for autos & buses, autos, and trucks, listed left to right. 420 ft from the inspection booths the right lane diverges to the commercial inspection area (1 inspection lane). There are three signs at the gore splitting the POV plaza and commercial lane. A large static overhead sign splits autos & trucks, a smaller static sign duplicates this message, and a trailer LED sign lists the nexus hours (note, the nexus lane is on the left side). 260 ft from the inspection booths the dedicated bus lane splits to the left of the POV plaza. At this point the POV plaza enlarges and follows a shallow “S” turn displacing the center of the roadway 80 ft. Due to the “S” turn signs at the canopy would only be visible from 550 ft away. The canopy is visible from the road at a 20 degree angle from the centerline at this point.

The port currently has a few static post mounted directional signs, identity signs, and statutory signs throughout the site. The site contains signs with multiple graphic standards including the CBP standard blue and white color scheme as well as a white and green color scheme. The primary directional signs for cars, trucks, and buses are written in English and French.

PROPOSED DYNAMIC SIGNAGE SOLUTION

Wayfinding

Highgate Springs is a challenging site from a wayfinding perspective due to the varying usage of the cargo lane as well as the shallow curve of the POV plaza.

These issues make the location and orientation of any signage critical to ensure the best sight lines and readability of the sign messages. Any signage solution needs to direct NEXUS users and RV drivers to the cargo lane during peak times as well as provide lane information for the primary POV lanes. In addition, the location of the lane signage should be clearly and intuitively associated with each driving lane.

In order to solve the visibility issues with the S-turn the design team has proposed placing the lane signage on an advanced gantry at the head of the POV plaza.

The position of the new gantry would be orthogonal to the driving lanes to better associate the signs with the lanes. The gantry would include a cantilever section over the median between the POV plaza and cargo lane. This section would allow for the placement of a sign directing NEXUS users to the cargo lane.

A number of static signage improvements have also been proposed to improve traffic flow at the port. New static sign panels that meet DOT standards will be applied to the existing gantry along the approach road to provide better information to travelers prior to the inspection areas. In addition, illuminated static lane number signs will be installed at the booths to replace the smaller existing signs for improved visibility.

The design team investigated two primary alternates for lane signage:

Alternate #1- New gantry in POV plaza and dynamic advanced warning sign on existing gantry

Alternate #1 was developed as the preferred installation since the use of an advanced gantry was determined to be more suitable for lane identification. Here the new gantry is aligned perpendicular to the POV plaza to better associate the lane sign with the driving lane. In addition, locating a second advanced warning sign on the existing gantry would provide important information and direction to the mixed-use cargo lane during peak periods. This sign would aid directing NEXUS and RV traffic to the cargo lane in advance of the plaza during peak traffic times.

Alternate #2- New gantry at the head of the POV plaza and updated static signage at the existing gantry.

Alternate #2 was developed to combine the functions of the two separate signs in Alternate #1. In this configuration a new gantry is placed above the start of the driving lanes at the head of the POV plaza. The signs at this location can still be clearly associated with the driving lanes. This gantry position also provides a mounting location for a cantilevered sign to the west to provide direction to the cargo lane. This sign could also be used to direct NEXUS and RV traffic to the cargo lane during peak traffic periods. Updated static signage at the existing gantry will improve the early warning and traffic sorting entering into the S-curve approach.

The design team also considered mounting the lane signs at the canopy. This approach produced a number of wayfinding issues causing this location to be eliminated from consideration. Signs at the canopy would be more difficult to associate with the inspection lanes due to the approach angle and viewing angle from the POV plaza. While the signs could be angled slightly and/or offset from the centerline of the driving lane they would still be difficult to see and read from the entry to the plaza. We also considered locating the signs at the booths themselves to better associate the signs with the lanes. However, the signs would need to be reduced in size with this approach in order to accommodate installation conditions, thus limiting graphic capabilities and text sizes. In addition, these signs would not be able to be placed at an optimal height necessary for visibility from a distance.

STRUCTURAL RECOMMENDATIONS

Proposed LED Signage Structural Support

The preferred signage support option for Highgate Springs in Vermont is a new standalone steel gantry supported by a concrete foundation. The gantry will span approximately 100’ across (5) lanes of traffic and will support (5) signs with an estimated weight of 290 pounds per sign. The bottom of the gantry must be set at an elevation to provide proper vehicle clearance.

The supports of the gantry should be protected from vehicle impact by installation of guardrails, bollards, or an oversized column base. The existing gantry structure will need to be assessed in order to support the new proposed static signage.

The following design criteria is to be used for design of the gantry, its foundations and connection of the signs to the gantry.

Structural Design Criteria:

The design of the LED Sign Support Gantry must be based on the GSA Facilities Standards for the Public Building Service P100, dated March 2014. This includes the 2012 International Building Code (IBC), ASCE 41-06 and ASCE 7-10. The facility is a Risk Category IV “Essential Facility”.

P100 provides specific criteria related to the design of structural components of buildings, including the following loading criteria:

Dead Loads:

• Gantry self-weight plus weight of permanent sign and electrical equipment

Wind Loads:

3% probability of exceedance in 50 years)

Seismic Loads:

Ip=1.5

Foundations:

• Presumably concrete spread footings. No soils report is available at this time.

Ice Loads:

• Per ASCE 7-10

Trenching and Site Demolition

Trenching is anticipated for proposed power and data conduits. Refer to electrical site plan for proposed conduit routing. Civil engineering will be required to define existing conditions and design parameters for trenching and utility layout unless GSA prefers for this to be undefined in the design-build documents.

ELECTRICAL NARRATIVE

Data:

A new rack-mounted server will be added to the existing rack in the server room on the first level of the main building. Power for the rack will come from an existing installed outlet. The conduit and cable to the new sign control desktop PC will route through the lower level ceiling space to the supervisor’s office.

The LED signage cabling will be installed in 1” conduit from the canopy mounted signs to the server room. Conduit will be installed underground in trench. Inside the building, conduit will be installed in the lower level ceiling space and routed into the server room.

Power:

Power for the signs will come from an existing 208/120V, 3-phase, 4-wire branch panel in the main electrical room. Each sign will have a dedicated 20A/1P breaker. The conduit and wire will route in underground trench to a gantry. Conduit will be routed along the gantry to each sign. A new override switch will be mounted in each primary lane booth to control the affiliated sign.

Meeting Notes GSA LED LPOE Package 1 Trip Report

Highgate Springs – September 10, 2014 General:

1. 24/7 Port

2. Few, if any commuters during working rush hours, mostly general and vacation traffic, 800 - 1200 vehicles a day.

3. Peak traffic during summer months, May to Labor day, peak wait times of 20 minutes, NEXUS traffic diverted to Cargo lane when wait times exceed 12 mins or so.

4. There is only one lane open at night.

5. Canada is enlarging the highway feeding into this LPOE with expectations that more traffic will use this route from Montreal to Boston

6. There are (5) POV lanes, (1) Cargo (not high/low), also used as Nexus Diversion from Lane (5) and (1) independent bus lane to the east.

7. Buses unload and they expect approx. 10 busses a day, typically Greyhound type.

8. Traffic maneuvering is a challenge particularly with RVs. Therefore, the preferred lane for RV’s is lane 5 for more maneuvering room.

9. Lane numbering starts on the west side of the Headhouse up to lane 5 with lane 6 separated from the other lanes by the Cargo Inspection Building.

10. There currently a Gantry support static advance warning signage between roughly half-way between the border and Primary. There doesn’t appear to be power to the Gantry.

11. Port currently uses temporary roll-out sign for holidays.

12. Connection to LED Signage to be in Command Center and Chief’s office.

13. The Headhouse is a (2) story building above grade.

14. They have a bad bird problem. Current Mobile Vacis Barn has been condemned due to Bird problem.

15. They are expecting a new generator project.

16. Future plans are for a Vermont DOT bypass lane to the west.

17. The team measured a underside of primary canopy clearance of 17’-6”.

18. Because of shape of canopy and clearance, signage is likely to be installed on the columns but with challenging clearance issues.

19. Lane widths were measured:

a. Lane 1 – 12’-1-1/2”

b. Lane 2 – 12’

c. Lane 3 – 12’-2”

d. Lane 4 – 15’-1”

e. Lane 5 – 12’-6”

f. Lane 6 – 20’-7”

g. Bus lane - NM

20. Drawings photographed on site show a different edge condition on the primary canopy than as-built.

21. Because of extreme curve immediately in front of the Primary, a new Gantry may be necessary possibly requiring a geotechnical report.

22. There is a potential for the existing bus lane to add a Nexus booth. The team will assess if this is an option appropriate for this project.

Structural:

1. The original drawings showing the structure of the building were available on site. Photos of the drawings were taken by the design team and a PDF copy of the drawings was requested. The primary canopy is steel framed and has a profile with a flat top and a curved soffit. The edges of the canopy taper to a thin edge which will make installation of the sign structurally challenging

2. The design team also considered the options of supporting signs from a steel member cantilevered off the steel columns supporting the canopy. This option may reduce the clear height

Meeting Notes of the lanes and therefore may not be viable. Lastly, the signs may be installed from a new gantry constructed in front of the port.

Electrical:

1. Service entrance equipment is located on the first floor.

2. This site has severe issues with birds. Netting has been installed under the canopy to prevent birds from perching on conduits.

3. Existing traffic signals and booths are fed from conduits mounted to the underside of the canopy.

New conduits will need to be installed in a similar manner and routed to the building.

4. The existing gantry is unpowered. New conduits would need to be routed underground across the truck lane and alongside the road. The size, quantity and location of existing conduits is unknown.

5. Spare capacity in existing panel boards is limited. However, Panel ‘MPE’ has sufficient unused capacity. Panel ‘MPE’ is the preferred source of new power for the LED signs.

6. The preferred location for the controlling computer is the supervisor’s podium.

Signage:

1. Description of Approach Road: The inbound road utilizes two driving lanes at the international border 950ft from the inspection canopy. The right lane starts to divide into two lanes 780ft from the inspection canopy. A gantry with three lane signs is located 550ft from the inspections canopy. The signs provide direction for autos & buses, autos, and trucks, listed left to right. 420ft from the inspection booths the right lane diverges to the commercial inspection area (1 inspection lane). There are three signs at the gore splitting the POV plaza and commercial lane. A large static overhead sign splits autos & trucks, a smaller static sign duplicates the messages, and a trailer LED sign lists the nexus hours (note, the nexus lane is on the left side). 260 ft from the inspection booths the dedicated bus lanes splits to the left of the POV plaza. At this point the POV plaza enlarges and follows a shallow "S" turn displacing the center of the roadway 80ft. Due to the "S" turn signs at the canopy would only be visible from 550ft away. The canopy is visible from the road at a 20 degree angle from the centerline at this point.

2. Wayfinding Challenges:

a. Directing NEXUS traffic through Cargo lane during peak traffic.

b. Lane signs at canopy should be rotated slightly for better visibility from sharper "S" turn at entry plaza.

c. Some RVs diverted to Cargo lane.

3. Booth Override Switch Location: Replaces existing switch for stoplights (to be demo’d)

4. Any Existing Signs to Remove: Upper column mounted stoplights to be removed.

5. Other Notes:

a. Preliminary location for signs is with a column mounted armature angled slightly (individual per lane).

b. 16mm display size preferred due to shorter reading distances.

c. 1 foot clearance between bottom of curved canopy and 16'-0" listed clearance.

d. Advanced sign at gantry necessary for when NEXUS lanes are diverted to cargo.
