Bidding a Pavement Project And Hiring The Right Contractor

Friday, April 15th, 2011

As they say, knowledge is power. The key to making a wise business decision is being educated on the subject. So if you are ready to have any pavement work done around your business, large or small, this is what you need to know before you even think about call a contractor.

Bidding a Pavement Project

1. Request For Proposal (RFP)
This is a method that is widely accepted within the industry when a client has a specific problem and needs that problem corrected. The client has an RFP prepared that clearly specifies the scope of work. This is usually done by an independent source, like a pavement consultant, reserve study engineer or by a contractor you trust. Once this scope is created, it is typically sent to three to five contractors and a pre-bid meeting is scheduled. A pre-bid meeting is another widely accepted practice within the industry. It involves the client, board members, building owners, anchor tenants, and the three to five contractors you picked. This meeting is designed to provide all key parties the opportunity to have a question and answer session. Usually, the RFP is tweaked at these meetings and little changes are made to accommodate either the contractor or the client. A successful pre-bid meeting will have the contractor leaving with a clear understanding of how he/she is to perform the scope of work. And, the client will leave knowing they are going to receive apples-to-apples bidding. It is vitally important that every contractor bid the RFP the same way. The client should avoid at all costs the instinct to send three to five contractors to a site with directions to “evaluate the property and bid the way you think it should be corrected”. This usually produces three to five different scopes of work with wide ranging price swings.

2. Reverse Bidding
This type of bidding has become more popular as budgets have become smaller. When a client needs more work, asphalt patching, sidewalk repairs, etc. then they have budgeted for, the client reveals their budget number to several contractors. For example, “I have $15,000 in the budget for asphalt repairs.” Those contractors then produce competitive bids on the volume of work they are willing to complete for $15,000. For example, contractor A will complete 275 square yards of repair, contractor B will complete 325 square yards of repair, and contractor C will complete 300 square yards of repair. In this scenario, the client would pick contractor B because they are giving you the best value. Once a contract is awarded, the client and contractor would visit the site and determine the worst 325 square yards of repair. If this practice is repeated year after year, a client can usually get a handle on an out of control pavement situation within a few years.

Hiring the Right Contractor

Once you have received an ample number of bids it is time to hire a contractor. You should ask for the following from your pavement contractor:

1. Contractors License: Every state has its own departments of licensing and regulation. This is the agency that issues business and contractors licenses. Make sure any contractor you use is properly licensed. ( My Contractors License Number is MHIC # 51204 )

2. References: Most reputable contractors are eager to furnish references. Check to see if the jobs were performed to satisfaction in a timely, professional manner.

3. A warranty: Too often, business owners or property managers find out after a disappointing experience that there is no warranty on the work. If a warranty is offered, get it in writing. Most contractors place their warranty information on their proposals.

4. A certificate of insurance: These are simple form letters sent out by request from the insurance company that insures the contractor. General liability and workers compensation insurance is easily attainable for legitimate companies.

5. Do not pay full cost in advance: Most state laws prohibit contractors from receiving more than 1/3 of the contract price at the acceptance of the contract. Find out the terms of payment and avoid contractors that only accept cash.

6. Get it in writing: Always get a written contract before you permit work to proceed. This should detail when work is to begin, the exact details of the improvements to be made, the quality of material to be used, an estimated completion date and payment terms. Read the entire contract before signing, including any small print.

The Benefits of Warm-mix Asphalt

Wednesday, April 6th, 2011

Warm-mix asphalt has been called the wave of the future, but what is it? Well, it is actually a generic term for several techniques used to reduce the temperature, by as much as 50 to 100 degrees, at which materials are mixed and placed on the road. This article from WarmMixAsphalt.com seeks to better explain this revolutionary new technology.

This drastic reduction in temperature has not only slashed fuel consumption, but it also reduced the production of greenhouse gasses, improving conditions for workers by cutting down on dangerous emissions. Warm-mix asphalt also allows for better asphalt compaction on the road, the ability to haul paving mix for longer distances, and the extension of the paving season.

But there are still several questions that must be answered before we crown warm-mix asphalt as the king of the road.

  • Can warm-mix pavements be opened to traffic quickly after construction?
  • What are the performance characteristics of these pavements?
  • In the case of technologies developed in other countries, can they be adapted to the U.S., where climate conditions are often more extreme?
  • If the production temperature is lower, does that mean that the binder does not age as much?
  • Will the potential for thermal cracking be reduced?
  • Will the potential for rutting be different?
  • Will the contractor have to use a different grade of asphalt binder?
  • What changes for the mix design procedure will be required?
  • Will the performance-graded binder in a warm mix perform differently from pavements produced at higher temperature?

Potholes and Repair

Wednesday, March 30th, 2011

How do potholes happen?

Potholes are severe manifestations of pavement fatigue cracking resulting in a total loss of asphalt integrity in a localized area. This creates a hole in the road. It is not uncommon to have a pothole extend through or into the aggregate stone base. Potholes occur when water seeps into cracks in the asphalt surface of a road or driveway. This water will freeze and expand in the cold weather. A pothole forms when dirt and gravel are forced out leaving a hole. The ice will eventually melt away, leaving a pothole.

How can you quickly fix a pothole in your driveway?

For a very wide crack or pothole, shovel in packaged cold-patch blacktop, leveling large areas with an iron rake. Compact the material with a rented tamper or the end of a 4-by-4. Add more material until the hole is slightly overfilled. Cover it with scrap plywood and drive over it.

If you are looking to fix a pothole on a commercial parking surface or if you want a top quality repair, it is probably best to call a professional.

What does My Pavement Guy have to say on the subject?

In the winter, potholes should be temporarily filled with a cold-patch mix material to protect against vehicle damage and/or lawsuits. Please note that this is only a temporary fix and left untreated correctly the pothole will most likely reappear. In the spring and summer months, potholes should be permanently patched.

Full-Depth Patching is the most common type of patching. This is where the pavement is completely removed in the troubled area and replaced. These areas are usually suffering from severe distress and / or sub-base failure. This is a permanent fix.

Pavement Maintenance

Wednesday, March 23rd, 2011

From the moment your asphalt is installed, it begins to deteriorate. This means that to ensure you have a top-notch parking lot for years to come, you will need to take certain steps to maintain that asphalt. This preventative maintenance will not only make your parking lot last longer, but, in the long run, it will save you money.

Here are a few simple steps you should take to keep your lot looking pristine.

Crackfill

Properly filling cracks is a job of tremendous importance. By filling a small crack properly, you will prevent that fissure from growing and becoming too big to handle by yourself. Filling small cracks saves you from paying to have large cracks repaired.

Sealcoating

This is another great way to improve the overall look of you lot while going the extra mile to protect your parking surface.

Re-Striping

Once the original lines are painted on the asphalt, constant re-striping is required ever 12-18 months.

Signage

Not only will your lot begin to deteriorate, but often signs are knocked down, dented, vandalized or even stolen. It is important to properly maintain your signs – not only for that instant curb appeal, but also for safety.

Wheel Stops

Wheel stops play an integral role in maintaining clear sidewalks and protecting signs. If your wheel stops are damaged, it could negatively affect everything around them.

Now you are well on your way to a beautiful, long lasting parking surface.

Benefits of Sealcoating/Resurfacing Treatment

Monday, March 21st, 2011

No matter what material your parking surface is made from, it can benefit from sealcoating or resurfacing treatment.

Unsealed pavement can allow water and other foreign materials to penetrate into its surface – leading to base erosion, freeze-thaw damage and pavement failure. Sealcoating provides your pavement with a protective barrier, which will not only make your lot last longer, but will also give your parking surface some instant curb appeal.

The Asphalt Institue states that, “The accumulation of moisture in pavement is probably the greatest cause of pavement distress.”

So do not wait for your lot to start cracking before you address the situation. Be proactive and sealcoat your parking surface as soon as possible.

As pavement cures, the sun’s rays dry out the asphalt – making the surface brittle. This oxidation causes accelerated erosion and if left untreated it can reduce asphalt thickness by as much as half within five years.

Take the necessary steps to keep your parking surface in great condition. A new sealcoat can restore that fresh black color to your lot. Not only will it last longer, but it will also look better.

Gas Prices May Hit $4 a Gallon Soon

Monday, March 14th, 2011

According to this piece on forconstructionpros.com gas prices will continue to rise this spring and summer.  The article interviews Dan Kieler who led the way around the flatbed truck and pointed to the gas meter. “Look at this, $200 for (around) 50 gallons,” said Kieler, who appropriately is from Kieler, Wis. He stopped to fill up while hauling some equipment for Epic Construction. “I think they’re higher than hell,” said Kieler, of current fuel costs. “A few years ago, diesel was always cheaper than gas. I don’t understand that.”

The article explains, “Fuel prices have increased significantly in recent days, as unrest continues in the Middle East and northern Africa. The Lundberg Survey of fuel prices released this week found the average price of gasoline in the U.S. rose 33 cents in the past two weeks. There’s a 25 percent chance gas prices for regular unleaded will rise above $4 per gallon by the summer, the U.S. Energy Information Administration said Tuesday in a short-term energy outlook. This latest increase has sparked a fresh discussion about just how high prices will go and what the remedy should be.”

Whether or not this increase will affect prices in the paving industry is hard to say. The article continues, “some business owners who make deliveries as part of their operations say current fuel prices are a concern, but they have not spiked enough to cause subsequent price increases. ‘We would have to see a pretty drastic change before I’d increase my delivery prices,’ said Andy Parker, owner of Custom Futons. Sue Butt, co-owner of Butt’s Florist Inc., said the business has a routing system for deliveries they try to follow. ‘Sometimes you need to be a little more creative,’ she said.”

It looks like we will have to wait and see how this increase in price will impact industries all over the country. For any of your paving needs contact My Pavement Guy at 410-636-8777 or here today!

2011 NAPA Meeting

Sunday, March 6th, 2011

The National Asphalt Pavement Association had its annual meeting in January in Orlando, Florida. As this write up announces, there was something for everyone in the pavement world.  Over 800 people attended the NAPA conference this year. The event contained four days of non-stop educational and networking opportunities.  From the Young Leaders’ hosted golf tournament on Saturday morning to the Super Bowl Diamond kick-off reception to the final evening dinner and dance event, it was declared the “best-ever NAPA Annual Meeting.”

As hotmix.org declares, “Highlights from the event include the “State of the Industry” address by four industry prognosticators, Jim Roberts, Granite Construction Inc.; Randy West, NCAT; and NAPA’s Mike Kvach and Howard Marks. Washington DC beltway insiders Pete Ruane of ARTBA and John Horsley, AASHTO gave attendees the current pulse on federal transportation funding and legislation. Keynote speaker, John Foley, a former Blue Angels lead pilot gave the crowd an outstanding presentation on what true, precise teamwork really requires and the benefits companies can learn from the rigorous training required to be a Blue Angel. To the delight of the attendees, NAPA’s Associate Members shared the history of equipment and the outlook for the future through the antics of the Ebenezer Skidmark family and their asphalt company in the fourth General Session.”

The educational sessions were filled to the brim during the entire conference. Some high points from the educational series were programs on asphalt cement pricing, economic outlooks, performance testing, the latest in warm mix provided timely tools and information to members. All in all, the conference was a great success. Next year’s event will take place at the JW Marriott Desert Springs in California, January 22 – 25.

Intersections: Asphalt Does Them Better

Friday, February 25th, 2011

According to this article produced by the Asphalt Alliance, asphalt has many benefits including its role in intersections. A new publication put out by the same organization titled High-Performance Intersections (which can be viewed here) lays out new helpful guidelines for pavement designers. These designers deal with many challenges in the asphalt process such as the difficulties of dealing with high volume places like intersections and other high-stress pavements.

“All engineers know that heavy, slow-moving traffic found at intersections, toll booths and other such locations can expose pavements to the highest stress levels possible,” explained Wayne Jones of the Asphalt Institute, one of the authors of the document. “But a well-designed, well-constructed pavement at these locations can deliver the same outstanding performance as all other asphalt pavements.”

High-Performance Intersections lays out a four-point strategy to ensure high performance at high-volume asphalt locations. To illustrate the principles, the publication chronicles two head-to-head competitions between asphalt and concrete intersections. Through much testing over the past 10 years this report finds “the strongest intersection” that has needed little to no maintenance. This intersection is in Illinois and is composed of a steel slag mixture that has held up the test of time and weight.

Asphalt Causes Less Carbon footprint than Other Pavements

Friday, February 18th, 2011

The production and installation of asphalt emits less greenhouse gases than other surfaces, reports this article. According to a recent study, asphalt pavements require about 20 percent less energy to produce and construct than other pavements. The less fuel that is used in the process—the less carbon dioxide that gets released into the air.

The article goes on to say that “Between 1970 and 1999, the asphalt industry decreased total emissions from plants by 97 percent while increasing production by 250 percent. Emissions from asphalt plants are so low, the EPA considers them as only minor sources of industrial pollution.”

Warm mix asphalt is another way that asphalt is cutting down on its emissions. The asphalt is mixed at a lower temperature than before, thus needing less energy to heat up.  Asphalt also helps to move traffic along quickly, allowing drivers to get to their destination rapidly. The process for applying asphalt is very fast so traffic does not usually result. This saves drivers time and also helps cut down on carbon dioxide released into the air.

The urban heat island (UHI) effect—the phenomenon that makes cities 2° to 10°F warmer than nearby rural areas on a hot summer day is another issue to consider. However, recently it has been proven that it is not necessarily the color of the pavement in the city that causes this effect but also the texture and thickness of the pavement.  This can affect the way a pavement retains, radiates, and/or releases heat. Research is being done to now to look into more porous surfaces that can help lessen this effect.
