EXAMPLE SPECIFICATION TEMPLATE

***********************************INSTRUCTIONS***********************************

This example specification template is intended to aid the purchaser in communicating requirements to contractors in support of potential acquisition decisions. Thespecification applies to active roadway vehicle barriers (referred to afterwards as the “barrier system”), which includes power-assisted or manualoperated active vehicle barriers.

The example specifications template is not exhaustive and should not be employed “as is.” The purchaser should adapt the specification template to suit organizational context (e.g., procedural and policy constraints or requirements), threat assessments, operational requirements, and site-specific context. The template uses an outline format and bracketed [] text to help the purchaser tailor the template.Bracketed [] text indicate items that should be defined by the purchaser. Notes (*) indicate information provided to the purchaser to help in understand the content and layout of the template. The purchaser can develop their own specifications template by:

  • First, conducting planning activities and research to better understand relevant context and possible implications of specification decisions. The example specification is intended to be used in concert with the Guide to Active Vehicle Barrier (AVB) Specification and Selection Resources, which highlights available resource and activities to conduct prior to and alongside specification.
  • Second, identifying additional examples of specifications from projects or organizations with relevant context. Such specifications will provide useful comparisons to this template to highlight areas that should be considered further before adopting. Uniqueorganizational or project context might lead you to adopt requirements very different from the examples identified in this template.
  • Third, modifying the scope of the specification content included in the example template by deleting or adding numbered levels. Adhere to organizational standards when editing the example specification template. Is each numbered and lettered section adding a requirement that the organization deems desirable and appropriate? If not, then delete that section or replace it with the appropriate substitute language.
  • Fourth, modifying the content of the specification text, by filling in the bracketed language. A first pass should identify and remove bracketed specifications, typically“SELECT” items, not appropriate or desirable to include as a requirement. The remaining bracketed content should then be defined or removed, and typically on a case-by-case basis for each project.

For bracketed text that says INSERT, the appropriate measure depends on the project context. Thepurchaser should determine the appropriate measure for each project and replace the INSERT bracketed text with that value for each project. For bracketed text that says SELECT, the measure is not always included or is typically one of only a few values. Determine whether to include the sentence as a specification consideration, and if the consideration is desirable, select fromone or more of theexamplesprovided (or an appropriate substitute). The final version of this document to be used for dissemination to the contractor(s) should be edited by the purchaser per their project specific requirements and have no remaining Bracketed [] text or *Notes.

  1. Barrier blocking dimensions must be provided ‘as certified/approved.’ [SELECT Alternatively, if a barrier system's dimensions are between the dimensions of two crash tested barrier systems that are otherwise identical, then that barrier system is also acceptable, pending review [INSERT by anacceptable approval entity, e.g. qualified engineer].
  1. Physical Constraints.The manufacturer must demonstrate within site drawings that the installed barrier systemis capable of (1) operating within the allowable site dimensions, and of (2) allowing or obstructing all expected vehicle types, including vehicles following alongside or behind another vehicle.The barrier system maymeet requirements by changing dimensions throughtemporary removal or reconfiguration, provided that the expected change(s) in configuration can be performed within [INSERT minimum operator time in hours] and does not require tools, equipment, or knowledge that aren’t readily available to the operator.

2.The barrier system must be compatible with the available power sources identified to the manufacturer, and the electrical supply standard shall be [e.g. 208VAC 1 phase 60 Hz]. Other power sources utilized by the barrier may be specified and agreed upon if justified by site drawings and barrier system design. Power backup systems shall be [e.g. 24 to 100 volt] or less systems.

3.Barriers indicated as portable or transportable shall be capable of manual and/or backup power operation independent of a locally available power source.

  1. Reliability.Barrier systems shall be capable of operating given normal operations specifications provided above with the level of maintenance outlined in the manufacturer maintenance manual, unless otherwise indicated by the manufacturer in the Manufacturer Submittals. The barrier system must provide maximum dependability and ease of maintenance.

1.The barrier shall perform without failure of any component necessary for continued operation of barrier for [e.g. 200,000] continuous cycles.

2.The motors(s)/operator(s) shall be capable of actuating the installed barrier system. Manufacturer shall verify that the motors(s)/operator(s) are suitable for operating the installed dimensions and weight, and are sufficiently sized for the expected speed and frequency of operations.

3.For heavy traffic, if applicable, the barrier should be demonstrated as capable of [30%-100%] duty cycle or continuous open/close cycles without failure due to overheating.

4.If available, manufacturer shall provide a description of tested or field conditions used to verify cycle performance, including presence of weather, traffic, and levels of performed maintenance. Cycle testing must be performed in a configuration where the active barrier itself is located in an outdoor location that will expose the unit to full sunlight and the effects of climatic conditions at the test facility (pollution, rain, snow, sleet etc).

5.The system must be designed to function consistently in the intended locations to which this specification document applies. If available, manufacturers should provide demonstrated success of installed barriers in similar site conditions, including duration and level of maintenance.

  1. Serviceability.Barrier shall minimize the level of effort to maintain the barrier.

4.Manufacturer shall indicate potential equipment failures requiring levels of maintenance greater than those indicated in maintenance manuals, including for accessories, to ensure barrier performance in local conditions and following accidental or intentional impact.

  1. Back-up and Manual Operation.The manufacturer shall describe how the barrier system is intended to respond in even of a power failure and emergency operations.

1.Power failure and emergency operating modes must not compromise safety or security. The system shall be designed to prevent an un-commanded motion or disruption of controls in the event of hydraulic, electrical, or mechanical failure. The system shall be designed to [SELECT open; close; remain in the last commanded position] in the event of hydraulic, electrical, or mechanical failure. Manual override option [SELECT shall; shall not] be provided.

2.The control system must provide back-up and manual operating capability for use in the event of a power failure. The manual operation of the barrier must be simple,with no use of tools or knowledge not identified by the manufacturer and made readily available in advance, and requiring no more than the intended staffing levels of [INSERT number, e.g. 1] person(s) using approximately [INSERT staff physical capacity, e.g. 267 N 60pounds of force]. The barrier must be capable of being returned to the secure position, in manual mode, in no more than [INSERT duration, e.g. 5 minutes].
