Perimeter Security Design Assistance Services

Sloan Security Group’s Physical Security Experts have unmatched experience in securing physical assets and personnel. Many years of reviewing, analyzing and constructing perimeter security solutions have developed strong capabilities in the analysis, design, and economical protection of critical facilities.

Whether it is developing construction plans for security solutions in oil refinery facilities or developing customized systems for remote communication sites, the Sloan team has done it all. Consulting services can be packaged within a design/install scenario or on a stand-alone basis.

We can help you in creating robust high security procedures that will meet applicable guidelines, create training for your personnel and guide you through future maintenance requirements.

The initial stage of the design process is vital to the overall direction of your project. Like in writing or planning a vacation, you will determine the needs of your project, the constraints that will govern the process, and your final goal.

Determine Your Risk

Determining risk levels can seem like a daunting task. A site’s purpose, location, and history means it faces a unique array of threats. There are several ways to approach this in order to guide the future design process.

One option is to work Sloan and our risk assessment partner, Event Risk Management Solutions, to produce a comprehensive risk model to start the design process. Another approach is to use New York City Police Department’s (NYPD) risk assessment calculator to inform your approach. Finally, your industry may have already published guidelines such as North American Electric Grid Reliability Corporation (NERC) Critical Infrastructure Guidelines (CIP) 014.

We can help you wade through the alphabet soup of rules and regulations.

Set your Requirements

Before considering the results of the risk assessment, it is important to note what standards your project may operate under. Sloan has experience designing to meet the following standards:

Obviously this is not a comprehensive list of standards your project may be subject to. Research must be conducted into regulations set by the local and national governments, as well as industry standards.

In addition to the requirements set by standards and regulations, the results from the risk assessment should be taken into account. If there is a risk that is either missing or insufficiently addressed by regulations, then a special note of this should be taken so it can be considered in future stages of design.

Other circumstances must also be considered during this phase. What is the time-frame of the project? Does the site lie in an urban or wilderness area? Is the security designed for an entirely new construction or is it an update to an existing system? How much can the construction process infringe on normal operations? The answers to all of these questions may have a profound impact on the rest of the process.

Know your Limits

The importance of a realistic budget cannot be overstated. However, developing a budget that works with the realities of the project is much easier said then done. Since this is preformed before a detailed survey of the site, it may be difficult to foresee potential problems that might need to be budgeted for.

With over a decade in the industry, Sloan Security Group has enough experience to give reasonable estimates as to the costs of a security project. We can help you in ensuring a reasonable budget is established to guide the rest of the project

With the initial planning of the project complete and the criteria set, work can begin on actual design of your solution. Generally, our designer’s generally follow the American Institute of Architects (AIA) philosophy, with the three previous phases being a part of their “programming” step.

Schematic Design and Rough Sketches

Using the constraints set during the planning process, an initial design can be created. An architect will prepare a set of rough sketches, known under the AIA process as the Schematic Design, to demonstrate the equipment that may be required and it’s location. A 3d model may be constructed during this process to aid in visualization. These sketches will be reviewed and revised until approved by the customer, where we will proceed to the next phase in the process.

Design Development and Refining the Design

Once the Schematic Design is approved, more detailed drawings can begin. Specific aspects of the design, like equipment, specific distances and locations, and required materials are determined. A survey may be preformed of the site to see if any environmental conditions (for example, a shallow layer of bedrock or caliche) would effect the building process. The procurement process traditionally begins once this stage is completed.

Construction Documentation

At this stage, the design has been approved by the customer and all requirements are known. A final design document, the classic “blueprint,” is prepared, detailing exactly what is required for each step of the construction process. At this point an exact cost for the project can be determined, as the majority of factors have been determined. This includes required materials, required parts and equipment (custom or third-party), and composition of soil.

Looking to improve your security?

Most frequently, Sloan takes what is known as a “50% design” from an architect or engineering firm and converts that to a 100% design.  Often, that means taking a concept drawing with some specifications to a full-blown, ready for construction shop drawing.

We can help you select, procure, design, install, and maintain your vehicle barriers, regardless of your situation and location(s).

There are a tremendous variety of systems currently on the market with new companies and products being introduced constantly. We keep a close watch on these new technologies and can help you select from amongst all of the options available. Our experience designing and installing a vehicle barriers across North America at a wide range of facilities including chemical/oil/gas, port, airport, and military facilities helps us to analyze your individual situation and ascertain which barrier solution will be most secure, cost-effective, and maintenance free solution for your situation.

Working together with you, Sloan will provide a solution that will:

  1. SECURE your site
  2. Meet your BUDGET
  3. Provide RELIABILITY

We help design to the following standards:

A barrier meant to stop, disable, or destroy vehicles intentionally driven into the perimeter of a protected area. These barriers may be active, (movable at the push of a button) or static, (permanently in a vehicle-stopping posture) and be located at gate entrances, or along perimeters between vehicle access points.

AVB= Active Vehicle Barrier

  1. Utilized for active vehicle entrances, sally ports, unmanned entrances
  2. Wedges, bollards, sliding, rising or pivoting horizontal beams, integrated into gates etc.
  3. Hydraulically, electrically, pneumatically, or manually operated
  4. May be surface-mounted, shallow-mounted, or standard depth installation

SVB= Static Vehicle Barrier

  1. Utilized for fence lines, permanently closed gate openings, temporarily closed gate openings
  2. Cable-type barriers, bollards, berms, trenches, walls, street furniture, vegetation, concrete barriers, guard rails etc.

Guard rails are crash rated but not for a perpendicular attack. Guard-rails (cable, steel, and concrete jersey-type) are only tested at a 15 degree approach angle commonly found in traffic situations. These systems typically fail when hit intentionally by vehicles.

This is an important question that must be answered before you get too far into your selection process. The definitions of these terms is found below and ensures that you have a good base understanding before you go further.

Standard Crash-Rated Barriers

Barriers which have been certified by a rating agency as having passed a full field crash test where a particular barrier is certified to stop the attack of a particular vehicle traveling at a certain speed within a strict set of guidelines. This rating does not serve as a guarantee but only as evidence of capabilities.

Modified Crash-Rated Barriers

Crash-Rated Barriers which need to be changed in some minor way to fit a particular site’s characteristics. The changes to the barriers should be carefully analyzed to ensure that the barrier’s effectiveness will not be affected by the changes.

Crash-Engineered Barriers

Barriers which have been engineered by a particular entity to stop the attack of a particular vehicle traveling at a certain speed within a strict set of guidelines. No field testing has been performed on these barriers however. These barriers are less favorable and should only be utilized when there is no equivalent Standard or Modified Crash-Rated Barrier available.

Why is this important?

  • Both crash-rated and crash-engineered and crash-rated barriers are engineered but even with modeling programs and extensive engineering expense, crash tests often fail.
  • There are companies that may have one or two products that are crash-rated but offer a dozen or more “crash-rated products”
  • Companies must be pushed to explain precisely what, if any, engineering or crash testing has been performed to give the buyer a clear view of what they are getting for their investment
