Latest Asphalt Repair Project From Calvac Paving

Calvac Paving's Project Redwood Shores

Modern technology and paving practices have revealed faster, more cost-effective solutions to problems that once would have required expensive tear-out and repaving operations. One of the best examples we at Calvac Paving have ever seen was the rehabilitation of the Redwood Shores parking lot we recently undertook. This project mixed new technology with time-tested techniques to deliver a great result for the client, faster and more efficiently than conventional paving methodology.

 

The parking lot itself was old, cracked and weathered from years of use, but not so bad as to need a complete removal and replacement. Age and oxidation from poorly placed asphalt atop moisture-sensitive base material had caused the asphalt to crack and dry out, reducing its flexibility and its resilience. The parking lot was in need of a major face-lift, and Calvac Paving had the perfect product and the years of specialized talents to make it happen. This was a very unique project in that it perfectly fit the criteria for a very specific application: a Petromat overlay.

 

Petromat is a non-woven reinforcing fabric that is applied using a liquid asphalt binder known as RS1, which works as a penetrating adhesive and moisture barrier. The Petromat fabric helps to retard the existing cracks from reflecting through the new asphalt surface and gives the finished surface a higher tensile strength, thereby distributes the weight of heavy truck traffic over a greater area. After that, a full two-inch placement of hot ½”fine asphalt is placed with self-propelled paving machines.  Once the asphalt has been placed, the compaction equipment follows immediately behind the paving equipment. These very large and heavy smooth drum rollers compact the hot asphalt to a dense, smooth and uniform finish.Day 2 of the project

Once the compaction process is completed and the hot asphalt has cooled, we then apply a fog seal mixture of 50% SS1 and 50% water. This is designed to help bond the top layer of new asphalt and give it that black shiny “new pavement” look. After the Petromat overlay is 100% completed to our satisfaction, we can proceed with striping and stenciling operations.

Because of the unique considerations and time constraints of the job, Calvac Paving recommended a 2” Petromat overlay over the entire parking lot, measuring approximately 63,500 square feet. This offered the best results for the budget and gave them similar benefits to getting a brand-new parking lot for years to come, without the hassle, expense and lost time of a complete remove and replace. This project also had some very unique parking design restrictions, offering a perfect opportunity for Calvac Paving to design a new layout for the regular and ADA stalls. This redesign included larger stalls, which helped prevent unnecessary dents in car doors, making both the tenants, and owners happy with their new parking lot investment.

How Many Parking Spots Will I Need For My Strip Mall?

Strip Mall

Happy Monday Everyone! In this edition of Maintenance Monday, one our social media friends sent us this question.  I own a strip mall in San Jose, we have 10 retail stores, with 75 parking spots. How do we figure out the correct amount of handicap parking spots to have?  The answer is…

Thank you, In this case, 75 stalls. Three would need to be accessible spaces (not handicap), of which one of those would have to be van accessible.  One thing to consider is the current count. If this property has 5 existing accessible spaces, it is best to put back those 5.  The reasoning is that the standards are the minimum and it is not usually a good idea to decrease accessibility on a property.  This is why it is important to plan these layouts with an ADA specialist, you don’t want to create a problem in the future by guessing or over estimating today.

How many parking spots do I need?

 

 

At Calvac Paving, we have CASp (Certified Access Specialists) available. Our CASp specialists serve the San Jose area as well as the greater Bay Area.


New Medical Building Parking Lot

Calvac Paving’s commitment to service means that we often have projects that present unique challenges. For a medical center in Menlo Park, there were several problems that had to be overcome. First, the base below the asphalt had become unstable, leading to depressions and potholes in the surface. Due to these conditions the existing asphalt had to be removed, the baserock graded and compacted. Second, the existing asphalt had to be off hauled and new pavement placed over the recompacted baserock. Finally, because it is an active office, we had to complete the removal, replacement and striping in a single Saturday.

When we first arrived, the parking area was riddled with potholes and puddles from the destabilized base. The existing striping and stall design of the parking lot was several years out of step with current ADAS and CBC standards for access. We then scheduled the off haul of recycle and import of hotmix asphalt tonnage and we mobilized the equipment and manpower necessary to complete the job, as well as staging the striping crew. Since we had a very tight window and no margin for error, we knew this had to be done efficiently and correctly the first time, with no delays. After blocking off the area so that we could work safely, we began grinding out the existing asphalt using a specialized milling machine. This pulverized the existing asphalt so that we could haul it to a local recycling plant, while exposing the existing baserock surface. Once that was completed, we graded and compacted the baserock so that Calvac Paving could create a stable, uniform surface that would create the necessary drainage and eliminate the puddles. This process, known as “grading,” is key to establishing a surface safe for vehicles and pedestrians while permitting stormwater drainage, which helps prevent subgrade destabilization by not allowing water to collect and seep through the asphalt.

Once the grade had been established and the baserock compacted to comply with industry standards and project specifications, we placed fresh hotmix asphalt in two 2” layers, or “lifts.” Compacting the asphalt in lifts as it was placed, created an end product that is more durable, less prone to cracking, potholing and other problems seen with asphalt paving. Once the second lift was placed, and we fog sealed the surface, we then had to layout and stripe the parking lot up to current ADAS and California building code requirements for correct access to the building and parking areas.

The result was a very smooth and puddle free, pedestrian, parking and driving surface that is far more stable than the previous paving, as well as meeting the latest standards. At the end of the project, we had removed and replaced more than 150 tons of hotmix asphalt in a single day, which was a quick turnaround for this volume of material and the job specific constraints.

Calvac Paving has been serving the Bay Area for over 40 years, from road rehabilitation projects in Los Altos Hills to this medical center parking lot overhaul in Menlo Park, and we have constructed, repaired or remediated thousands of properties. Each project requires a slightly different approach, due to project requirements, schedules, access concerns and other factors. We pride ourselves as the Bay Area’s solution to those supposedly “challenging” jobs, combining our reputation for safety and efficiency with the attitude that there’s no reason to consider a job “challenging” with the right safety, tools, training and equipment.

We also offer an industry-leading three-year warranty on the finished product to our qualifying clients as proof that we stand behind our product and the workmanship that goes into it. We are committed to providing our clients and stakeholders the best and most efficient results in the business, while making sure that the product that we leave behind is one we can look back at with pride.

Calvac Paving Obtains ADA-CASp Certification

Calvac Paving Leaders in ADA ACCESS

The Americans with Disabilities Act, or ADA, sets very strict standards for commercial construction to ensure that people with physical disabilities have full access to public buildings and places of all kinds. Because the provisions of the ADAS, ADA standards, are constantly evolving, many construction and architectural firms, local and state inspectors are unaware of how the different aspects of ADA codes impact the specific construction of various structures, including the need for ramps, compliant parking stalls and upgraded access and barrier removal in the case of building remodels and renovation.

ADA certification in the form of CASp is particularly important in the state of California, because of the constant turnover of property management and ownership. Often the first sign that anything is amiss with a particular building or business’s ADA compliance comes in the form of a property inspection, visitor complaint or drawing revision, with expensive consequences in exposure to litigation, retrofitting to comply with California Building Code and the ADA standards and other related costs of remediation. While CASp certification is not yet commonplace, it is believed to become far more important among construction-industry professionals in the coming years.Middle view of ada ramp install

Calvac Paving has been serving the Bay Area for over 40 years, and has been closely monitoring changes and amendments to the ADA standards since they were first put in place in 1991. Several years ago, Calvac Paving’s President, Jim Adam, decided to take this aggressive monitoring several steps further and pursue full CASp, or Certified Access Specialist, certification. This rigorous training and certification program requires applicants to be fully trained and cognizant of issues concerning building and business access for disabled persons at both the state and federal levels to ensure compliance with all ADA provisions.

Jim explained that his purpose in seeking this certification was to better serve Calvac Paving’s clients and the general public. “By training for years to understand the history, goals and application of the Americans with Disabilities Act, I am better equipped to ensure Calvac Paving’s clients a final product that will provide the barrier removal and access that the current CBC [California Building Code] and ADAS require on their properties.”

The CASp certification benefits all the stakeholders in the building process, as well as the general public. “{CASp} certification gives a confidence level that the project will be correct and that you will be able to avoid potential litigation…while getting the final product you need to be CBC and ADAS compliant.” As more construction professionals become CASp certified, Jim says the multiple points of view will help to reduce conflicts between differing objectives and strategic building outcomes while ensuring all members of the design and execution team are familiar with the code requirements that ADA imposes. Jim says this is a win for everyone, but especially the end user, which is why he sought out CASp certification to begin with.

He says he’s known for years that ADA certification would be an important step in Calvac Paving’s future ability to serve clients and the public more effectively. “The process for me started more than ten years ago when I hired ADA compliance experts to educate myself, our estimators and lead field personnel long before there was a CASp program. Then a couple of years ago I started the training process to become CASp certified. We’re trained and tested on all barrier removal and accessibility codes…it allows us to be true experts in barrier removal.” Jim also feels that Calvac Paving benefits directly from his ADA compliance expertise, because it allows him to ensure his crews can do their jobs more efficiently and “do it right the first time,” as he puts it.

Having access to the CASp certification gives Calvac Paving another powerful tool to serve its clients and help reduce potential compliance issues and costs for everyone involved, and Jim believes that as CASp certification grows in popularity, it will further establish Calvac Paving as an industry leader in ADA compliance and building accessibility for all. This, he feels, will also give stakeholders more confidence and alleviate concerns about whether or not their buildings and businesses meet applicable building codes for accessibility.

Calvac Paving Maintains High Safety Work Record

O.S.H.A.

The construction industry requires a delicate balance between worker safety and work completion and efficiency. At Calvac Paving, we value the safety and health of our employees as an integral part of our Business Plan. While many companies say this, we are pleased to be able to provide hard numbers to prove it. Our Ex-Mod(California Modification Rating System) rating of 74 with our workers’ compensation insurer is one of the lowest in the industry. This means that over the last three years, our experienced workers’ compensation losses have been 25% less than the conventional wisdom of the insurance industry said they should be. All this sounds very impressive, but what does it actually mean? Here’s a closer look at why this is big news for Calvac Paving and our valued clients.

Calvac Paving Crew Hard At work

What Does Ex-Mod Really Mean?

In simple terms a company’s  experience modification compares actual losses to expected losses. The experience rating system, in essence, adjusts the premium an employer will pay based on a comparison of that employer’s history of payroll and claims (collectively referred to as “experience”) to the average experience of other employers within the same classification. The result of this comparison is an experience modification. A Ex-Mod rating of a  100 is average, and pays 100% of the customary premium for coverage. Likewise, a company with an ex-mod of 125 would pay 125% of the industry average premium, because of the higher risk and nearly certain greater expense involved in the carrier keeping this company on the books.

Calvac Paving’s rating of 74 is well below the industry standard and means that we pay less than 3/4 of what many of our competitors would for identical workers’ compensation coverage. The best performers in the industry rarely reach an ex-mod of below 70, because insurance carriers can hardly afford to give away their coverage. However, our ex-mod does provide a verifiable, actionable metric by which to measure worker safety and the likelihood of on-the-job accidents and injuries among our employees.

How Is Ex-Mod Calculated?
The State of California’s Worker’s Compensation Insurance Rating Board put new rules in place for 2012, based on recommendations from the state insurance commissioner in 2008. These rules state that insurance ex-mod is calculated every year as an average of the data from the three preceding calendar years. The WCIRB guidelines require that insurance carriers provide an ex-mod score statement each year, usually at least 30 days before renewing the premium. These guidelines are intended to incentivize good occupational health and safety practices and limit workers’ compensation claims, but at Calvac Paving, we just call that business as usual. The financial perks that come with having a great safety record are always welcome in the business world, but what really matters to us is what our ex-mod means in the real world: the fact that our employees go home every night to their families in the same condition they left the house in the morning.

What Does Our Insurance Broker Say?

Our insurance broker, NFP/Thoits Insurance, consistently praises our safety record and the programs we use to improve it. Because we take our people’s safety so seriously, we incorporate training on every aspect of construction safety, site and roadway hazards and first aid training. We work closely with our carrier to implement and maintain a sound, viable loss prevention strategy, including IIPP and Early Return to Work programs that help our employees get back to work sooner while remaining in compliance with their healthcare provider’s orders. Because of these factors, our broker has consistently praised our programs and proactive worker safety initiatives, even going so far as to note that our programs are paving the way for future improvements.

From The Principals

Calvac Paving’s Principals are justifiably proud of the company, management and employees for the way they have worked together to make a safer workplace a reality. By continuing to train employees in proper on-site safety protocols and emergency measures as part of a program that meets Cal-OSHA standards for workplace safety, Calvac Paving is leading the way in setting the highest benchmarks possible for worker safety and lost-time injury prevention. Even more importantly, it means Calvac Paving’s employees get to enjoy more productive working days and quality, healthy time with their loved ones when off the clock. While construction continues to be a challenging field in which to balance productivity and safety, we take great pride in proving it’s possible every day.

Over the past 40-plus years, Calvac Paving has grown to become one of the largest Bay Area paving and asphalt contractors. From business owners that need new concrete sidewalks and ADA ramps to schools that have old and cracked asphalt parking lots that are in desperate need of repair, the friendly and experienced team at Calvac Paving is ready and able to help.

In addition to offering top-notch service, Calvac Paving’s website is exceptionally user-friendly, providing visitors with in-depth explanations of the various services they offer. The educational articles not only describe what each service entails, but when it is typically needed. This can help business owners, commercial property managers, homeowners association managers and many other clients to educate themselves and their clients about what work is needed at their properties.

For example, the article about asphalt repair explains that interconnecting cracks called “alligatoring” are typically found in high traffic areas or near dumpster enclosures.

“In the areas of the pavement surface where failure is showing (areas of ‘alligatoring’) we may propose removal of the failed asphalt and replacement with a thicker cross-section of newly placed and compacted asphalt,” the article noted, adding that Calvac Paving will mill, saw cut or jackhammer the perimeter of the failed areas.

“It is recommended that the new ‘patch’ be placed at a minimum thickness of 1-1/2 times the original asphalt depth to bridge any inherent weakness in the base material in that area.”

Anybody who would like to learn more about Calvac Paving is welcome to visit the user-friendly website or Facebook Page at any time; there, they can read more about the high quality services they offer.
