HOUSTON, TX 77002

10/10/2014

1.0 PROJECT OVERVIEW

This task order is for the construction of a sallyport/elevator at the Bob Casey Federal Courthouse, Houston, TX 77002. The project will require parts and labor as specified below.

2.0 GENERAL INFORMATION

Specific work items are listed below.

EXECUTIVE SUMMARY

The United States Marshals Service addition of a security sallyport and elevator to the northwest corner of the existing Bob Casey Federal Courthouse Building is an important opportunity to reduce vehicular congestion within the existing north security wall perimeter parking lot where the judges and government officials park and where the transport buses currently unload and load prisoner’s for processing, detainment, and court appearances. The newly proposed USMS Sallyport will allow the transport buses to utilize the newly attained easement property directly to the west of the Bob Casey Federal Building for the construction of a secure sallyport and prisoner elevator from grade level directly to the 10th floor (directly into the USMS secured level). A new secure elevator will allow the current Bob Casey judges/freight elevators within the courthouse to be used as intended for the judges and the movement of freight while removing the element of a security detail to escort prisoners to the 10th floor as the facility is currently being utilized. There are multiple factors that the USMS Sallyport must contend with. The first is the amount of existing underground utilities within the easement property that has been attained from the city for the construction of this project. The utilities range from an existing 6” water supply line for the city to electrical and data cables for the Theater District, as well as street light electrical systems and light poles. All of these utilities will have to be properly identified during construction and re-routed within the very tight site constrictions with the new sallyport structure. The second factor is the existing stairwell that allows access from the underground parking garage to the surface at Capital Street.

Measures have been taken to ensure that the City of Houston has sufficient vertical access in other areas that the removal of this stairwell will not present a problem to GSA. The third issue is the current Metro Light Rail expansion work on Capital and Rusk streets where the street configuration and underground utilities are being altered and will present an additional challenge in coordination.

At this time, Metro’s construction team is willing to make minor revisions to accommodate the Government’s requirements since the Metro Light Rail expansion work is already under way. This should allow minor work by GSA to finalize this area during construction. The fourth issue is the design restrictions in accordance with the State Historic Preservation Office (SHPO). The proposed design has gone through multiple design changes reviewed by GSA and SHPO where the final accepted design dictates the use of a lower elevator shaft with an MRL Elevator and the use of polished white concrete masonry units.

OBSERVATIONS AND ANALYSIS The USMS has a range of requirements and specifications for special purpose and support spaces that must be met. The sallyport consists of several key spaces: 1) Vehicle Sallyport, 2) Weapons Closet, 3) Prisoner Circulation, 4) Elevator, and 5) Mantrap Sallyport.

Standards require a vehicle sallyport to be screened from public view or views from any adjacent properties, be paved in concrete, and to have intercoms and cameras monitoring. The sallyport must have a roof, solid walls, and high-speed rolling overhead doors in accordance with USMS Requirements and Specifications for Special Purpose and Support Space Manual (Publication #64).

USMS Guidelines call for the vehicle sallyport to accommodate at least one of the largest vehicles typically used (50ft. bus) or two smaller transport vans and provide for a covered and secured area for prisoners to be unloaded and loaded and for minor vehicle maintenance and washing. This space is to be sprinklered, and monitored by security cameras controlled from the USMS command and control center. There was a specific request by the USMS to provide for a weapons closet with a minimum of 36 square feet in which a variety of weapons lockers can be stored for the Marshals use. This space is to be a moderately conditioned space with a security rated ceiling and scramble pad detention grade door access. The prisoner circulation area must be a minimum of 5 feet wide with glazed CMU walls and a security rated ceiling with duress alarms and security cameras monitored from the USMS command and control center. The configuration of the sallyport at the Bob Casey Federal building has created a space that allows for greater than 5 feet of width as well as a small additional area for a US Marshal to guide the prisoners into the elevator while not impeding the prisoner traffic flow. This space is a moderately conditioned space with a security rated ceiling and scramble pad detention grade door access.

The elevator has several specific requirements, among them being a sliding detention door and security screen within the cab to divide the US Marshals from the prisoners being transported vertically. The smaller deputy compartment contains the control panel operated by a deputy who is connected by intercom to the USMS command and control center. All surfaces within the cab are stainless steel with security rated light fixture and an access panel in the deputy compartment. The type of elevator is not directly dictated but in this case an MRL (Machine-room-less Elevator) was selected in order to minimize the space requirements for a separate Machine Room. Due to site constraints a traditional traction elevator would have forced the machine room to be located above the elevator with access to the roof since the judge’s chambers could not be impacted on the 11th and 12th floors of the Federal Building. The use of an MRL allowed for a shorter elevator shaft and was ultimately accepted by the State Historic Preservation Office (SHPO) since the Bob Casey Federal Building is now considered a Historic structure. The “Mantrap” Sallyport is a man-sized vestibule with a door at either end and functions as an interlock. The mantrap sallyport is the transition space between the prisoner and restricted or public space and is to be equipped with glazed CMU walls and a security rated ceiling with duress alarms and security cameras monitored from the USMS command and control center and is a moderately conditioned space with security rated ceiling and scramble pad detention grade door access. This sallyport exits out into the existing Bob Casey Secured parking lot where additional security is already in place.

DESIGN PROGRESSION

The original design of the elevator system was to utilize a traditional traction elevator system. Being that the grade level was very restricted, the elevator machine room would have to be located either under the elevator (which was quickly eliminated due to severe cost implications) or locating the machine room at the top of the elevator shaft, requiring either access from a floor level above the 10th floor to the roof. The 11th and 12th floors were both determined to be inaccessible due to the locations interfering with existing Judges Chambers, forcing the traction elevator system to reach above the existing roof line for an accessible Machine Room. The exterior materials of this design have had multiple transitions. The original architectural approach was to enforce the use of shellstone panels at corner edges to integrate with the existing Federal Courthouse materials (white shellstone) while using a different material at the vertical transition of the elevator shaft against the Courthouse to differentiate the two structures. The transition materials ranged in concepts from tempered dark glass panels to dark split-face CMU. The USMS did not want any glass panels in the design and preferred to see solid materials. At the time of the 35% submission, the design was utilizing shellstone panel corners and darker toned split-face cmu at the transition. Based on the projected cost of running the elevator to the roofline, it was determined that the elevator type would have to be changed to remove the machine room altogether. From this direction an MRL (Machine-Room-Less) elevator system would have to be used and the design shifted to this type during the 35% to 65% submission, requiring a substantial plan revision. Multiple exterior design options resulted from this configuration, also using a darker toned split-face cmu at the vertical transition between the two buildings to separate the two structures. Several submissions to the State Historic Preservation Office were made in conjunction with GSA and the ultimate design materials were driven by those entities, changing from shellstone (which matched the existing building) to polished cmu. Costs of using oversized masonry were found to be more economical than standard sized cmu as well. The use of white oversized polished CMU units was selected for the entire exterior surface of all new structures, including the in-set vertical transition.

The design at this point has less of a visual impact, no differentiation and matches the existing building in color only, but was approved by SHPO.

Initial concept rendering with access to the 11th floor using a traditional traction elevator with shellstone panels and a dark glass vertical transition or dark split-face cmu vertical transition. The design of the elevator shaft using a traditional traction elevator with access to the roof with shellstone panels and dark split-face cmu at the vertical transition. This rending now shows the use of an MRL elevator with limited shellstone panels and a larger use of split-face cmu with a dark vertical transition between the two structures. The final submitted rendering of the new sallyport uses oversized white polished cmu units in its entirety, including the inset vertical transition.

Civil Design Storm Drainage: The existing drainage pattern at the location of the proposed Bob Casey Sallyport is from south to north. The grade of the proposed driveway follows the existing grading and drainage patterns. Trench drains the full driveway width, are called for, between Rusk Street and the sallyport structure to intercept storm water runoff. Between the sallyport structure and Capital Street, storm water run-off is collected by a series of Junction boxes / Type ‘A’ Inlets and a Type ‘BB’ Grate Inlet. The trench drains have been sized to capture all of the anticipated storm water run-off generated, from the proposed driveway and the immediate surrounding area, between the North right of way line of Rusk and the sallyport. Storm water collected by the trench drains is conveyed under the sallyport via an 18-inch diameter reinforced concrete pipe to a series of Junction Boxes / Type ‘A’ Inlets located north of the sallyport. The storm water is then routed through the junction boxes to the City of Houston storm sewer on Capital Street via a 24-inch reinforced concrete pipe. The storm drain connection to the City of Houston storm sewer system is at an existing Type ‘BB’ Inlet located along the south curb line of Capital Street. The existing Type ‘BB’ Inlet will be adjusted and converted to a Type ‘BB’ Grate inlet to accommodate the proposed sallyport driveway. Water: A 6-inch water main is being relocated to accommodate the proposed sallyport structure, associated storm drainage, sanitary sewer lines and sewer appurtenances. The City of Houston has determined that the 6-inch water main, located in the existing utility easement along the west side of the Bob Casey Federal Building, must remain in service.

Sections of the new 6-inch water main must be encased in a 12-inch diameter steel casing to comply with City of Houston requirements and Texas Commission of Environmental Quality, (TCEQ) regulations. The 6-inch water main will be connected to existing water lines located in the Capital and Rusk Street rights of ways. An existing fire hydrant, located at the intersection of the proposed sallyport driveway and Rusk Street, is within the proposed drive and will be relocated. The fire hydrant will be relocated to the east side of the sallyport driveway.

Sanitary Sewer: A sanitary sewer service connection is required to serve the internal floor drains and elevator sump drain. A proposed 6-inch sanitary sewer line will run from the sallyport to an existing sanitary sewer stub located within the Capital Street right of way. The sallyport floor drain and elevator sump drains are routed through an oil and grit separator prior to the connection of the City of Houston sanitary sewer main. A portion of the sanitary sewer will be encased in a 12-inch diameter steel casing due to its proposed location and to comply with TCEQ regulations. A portion of the sanitary sewer is located parallel to and below the proposed 24-inch RCP storm sewer.

MEP DESIGN

Mechanical Systems:

1. Cooling/Heating: Cooling and heating of the Prisoner Circulation Area, Weapon Closet, Mantrap, Electrical Room and Control Closet are accomplished through a VRV (Variable Refrigeration Volume) heat pump system. Each area is independently controlled through separate AHU’s controlled via infra-red remote control devices. Although simultaneous heating/cooling is not available, each area can be controlled to a different temperature within a heating or cooling mode.

2. Garage Exhaust: The Vehicle Sallyport has 1-1400 cfm garage exhaust fan.

This fan draws air in from 2 separate air intake louvers and is controlled via a CO (carbon monoxide) sensor which cycles the fan on and off.

3. Elevator Shaft Exhaust: The elevator shaft is provided with an air circulation and exhaust system. Air, 1,200 cfm, is drawn in from the top of shaft and exhausted at an elevation of 84” above grade. This air will tend to keep the shaft fresh and will work in tandem with the elevator cab ventilation fan provided with the elevator.

4. Fire Sprinkler Piping Freeze Control: The main Vehicle Sallyport is equipped with 4-5KW electric fan heaters. These heaters are designed to maintain the Sallyport temperature above freezing in the winter time as to not allow the fire sprinkler lines to freeze.

Electrical Systems:

1. Power: The main power is supplied via a 200A 480V, 3-phase, 4w feed from a main buss duct located in the main buildings first floor electrical room. This feed is brought to a 480V 200A panel in the main sallyport electrical room. This primary 480V power is used to power the new elevator and the 4 new vehicle area electric heaters. It also supplies a new 45KVA 120/208V transformer and 120/208V panels which supplies power to lighting, HVAC components, exhaust fans, gate openers, elevator cab lights, roll up doors, elevator sump pump, elevator auto rescue system, security system and general receptacles.

2. Emergency Power: Emergency power is taken from an existing 200A, 120/208V, 3-phase emergency panel located in the basement electrical room. A 100A feed is brought to a new 100A, 120/208V 3-phase panel located in the new electrical room. This panel provides emergency power to the sallyport lighting and security cameras.

3. Security Features: The new sallyport is equipped with an extensive array of fixed and motor operated security cameras. A vehicle sensing system (imbedded loop) operates security gates in and out of the sallyport. A scramble pad controls movement between various areas of the sallyport such as weapons vault, control room, man trap etc. There is also a signal system which alerts the prisoner-bus driver of oncoming traffic when leaving the sallyport and a system which interfaces with Metro to coordinate the Metro Rail bus’ and the prisoner bus.

Fire Alarm System:

There are fire alarm horn strobes in the Prisoner Circulation Area, Weapon Closet, Mantrap, Electrical Room and Control Closet to alert of fire hazard. The elevator shaft has a smoke and heat detector located at the top of the shaft. The elevator lobby has a smoke and heat detector and a phone receptacle for communication by firemen. The elevator has an auto rescue feature which, upon notice of an event from the main fire alarm system, will bring the elevator down to the next accessible level.

Plumbing Systems:

1. Water: Water is supplied from an existing 1” supply line located at an existing restroom adjacent to the new sallyport. This water line supplies water to a new hose bib, to be used for vehicle washing, and new trap primers.

2. Sanitary System: New sanitary waste piping from the sallyport floor drains and the elevator pit pump run to a new 8” sanitary branch line via a new sand and oil separator. The new 8” sanitary line, provided on the Civil Engineering plans connects the sallyport waste system to an existing City of Houston sanitary sewer.

3. Storm Piping; New storm piping from new roof drains on the elevator and circulation area roofs and any storm runoff collected in 3 new trench drains will be routed to an existing City of Houston storm sewer.
