Apparatus Purchasing: Evaluating an Outside Spec Writer, Part 1

The Rush (NY) Fire District operates three pumpers, a heavy rescue, an ambulance, a combination brush and utility vehicle, an all-terrain vehicle, and two trailer-towed boats out of two stations covering about 40 square miles in western New York. Staffing is about 50 strong-all volunteer and provided by the Rush Fire Department, Inc. Sixty percent of the district's 392 calls in 2014 were emergency medical services-related.

In early 2012, the district's apparatus purchasing committee (APC) began planning the purchase of a replacement pumper. In mid April, the committee recommended that the district retain an outside (third party) spec writer to "interact with apparatus manufacturers to coordinate preparing purchase specifications" for the new pumper.

The district did not retain the spec writer as a professional consultant. The objective was to consolidate the APC's ideas and coordinate with apparatus manufacturers (OEMs) in preparing an "open" specification. It was agreed the spec writer could challenge the APC and make suggestions only to improve the purchasing process-not the committee's decisions on content. As an example, the quantity of hard suctions specified by the APC was not subject to debate; how and where to store them was open to suggestions and recommendations.

Articles describing new purchases usually heap praise on the manufacturer and the local dealership describing how helpful both were. APCs receive equal accolades for their work. Seldom heard from is the local salesperson who directly interacts with a purchaser. 4 Guys Fire Apparatus was the successful bidder for the Rush pumper. Frank Riccobono is a salesperson for Firehouse Apparatus, Incorporated, the local 4 Guys dealer. He agreed to be interviewed for this article. His answers below are very interesting.

Initial Design and Layout

Did you feel isolated from the apparatus purchasing committee?

To a degree, yes. When you see the spec for the first time, you try to imagine exactly what they are trying to build. With most customers, we'll meet several times before the truck goes out to bid, so even if the customer publishes another manufacturer's specification, you have a good handle on what they are trying to build. If a purchaser elects to use a spec writer or a consultant, the APC needs to remember to allow sufficient time for the bidders, as we are starting with a blank sheet of paper. With Rush, it was not an issue. Sometimes it is.

Did you think anything was missed by not working directly with the APC?

The one thing that was missing is you don't get a chance to build a good rapport beforehand. Normally, when you work directly with an APC, you have the opportunity to showcase your product. You also get a feel for whether you have a chance selling the truck. You get to meet each committee member before the bid. In this particular case, I didn't have a good feeling until the APC invited me to sit down and discuss our proposal. This first sit-down is where I was introduced to each committee member.

Did working with a third party via e-mail and telephone save you physical time?

I think it saves some time when questions arise about the intent of a particular item in the spec. If the spec writer has a good understanding of fire apparatus, I don't have to spend a lot of time trying to explain an issue to the APC. The spec writer has to do that. The concern that we have on our end is we have no idea if the spec writer is using due diligence. In this particular case, I knew the spec writer and I knew he had an extensive background in fire apparatus, so that made it easier. That is not always the case.

Air Pressure, Weight Capacity, and Speed: Getting to Know Tires

Of all the components that make up a fire apparatus, tires could be considered the most critical. Without them, moving the vehicle would be extremely difficult.

WESLEY D. CHESTNUT

They bear the weight of the entire vehicle. Not that anyone can tell it in states where road conditions are poor, but they do provide some cushion for little cracks or rises in the road. Tires may seem like relatively simple components on a fire apparatus. However, consider them one of the most complex components and arguably one of the strongest.

People may not realize it, but there is critical information imprinted on the sidewall of each tire on a fire apparatus. If certain information is not adhered to, such as tire inflation pressure and load carrying capacity, there could be detrimental effects to the tires. Speed is another factor that can significantly impact tires. And, in certain cases, tire speed limitations may not be on the sidewall.

Tire Inflation

Tire inflation pressure is related to the load-carrying capacity of the tire and may vary depending on the tire as well as the total weight of the apparatus. The units of measurement are given in pounds per square inch (psi) or Kilopascals (KpA). Operating an apparatus with a tire having more than the required inflation pressure (overinflated) or not having enough air in the tire (underinflated) can cause damage to the tire.

An underinflated tire may deflect when driving, thus causing heat to be generated. Prolonged driving under this condition could lead to tread separation and other damage to the tire including a complete blowout. Telltale signs of an underinflated tire are tire bulge, the apparatus pulling to one side, or the tire feeling "loose" in the rear of the apparatus. The best way to eliminate tire pressure issues is to check the pressure frequently.

Overinflating a tire may result in the tire having less contact with the road than designed. On a steer axle, this could reduce the traction when cornering and result in an increased turn radius. Damage could occur to the tire when hitting a pothole or other objects on the road. An overinflated tire is not as easily detected as an underinflated tire. National Fire Protection Association (NFPA) 1901, Standard for Automotive Fire Apparatus (2009 ed.), requires a tire pressure monitoring system to be installed on new compliant apparatus. This provides a means of easily checking tire pressures, which should be done on a frequent basis.

Weight Capacity

Weight capacity is also indicated on the side wall of the tire. The units of measurement are given in both pounds (lbs.) and kilograms (kg.). Overloading a tire can cause premature wear as well as heat buildup in the tire similar to that of an underinflated tire and yield similar results. It is absolutely critical when considering replacement tires for the apparatus to install a tire of the same load rating. When considering a new apparatus, consider using the Fire Apparatus Weight and Cube Calculator found on the Fire Apparatus Manufacturers' Association's (FAMA) Web site at http://www.fama.org/fireServiceResources.cfm. By using this tool, the estimated amount of weight being applied to the apparatus will allow your apparatus manufacturer to determine the tire size the apparatus will require.

Intermittent Service Rating

Within the fire apparatus industry, apparatus manufacturers may receive a special capacity rating for tires that differs from the rating identified on the sidewall. This is referred to as the "Intermittent Service Rating" and mean
