Calvac Paving Continues To Maintain A High Safety Work Record

In 2015, we reported Calvac Paving has maintained a high degree of safety, as measured by reduction adjustment to our worker’s compensation insurance premiums. These numbers are released annually, which means we just received the latest figures on our performance. The 2018 California Experience Modification ratings for workers’ compensation insurance have now been released, and once again Calvac Paving is proud to be an industry leader in workplace safety! 

IMG_6064

Calvac Paving’s rating of 76 is well below the industry standard and means that we pay nearly 25% less than what many of our competitors pay for identical workers’ compensation coverage. This means we have had more than 25% fewer incidents and lost working hours than industry actuaries would anticipate for our line of work. Obviously, this is better for our employees and the company as a whole, because it means our training programs and safety protocols are working, and of course, the financial benefits are welcome as well. However, this means a lot more than just a bump in the bottom line to us at Calvac Paving. 

 

An Ex-Mod score of 100 is considered “average,” while an Ex-Mod of 125 would be “high-risk.” Employers with an Ex-Mod of 100 pay the full premium for their worker’s compensation insurance, while a high-risk employer would pay the full premium plus 25%. This metric means our employees are more likely to practice sound safety on the jobsite, while in transit and at the yard, increasing the odds they will all get home to their loved ones in the same condition they left for work. This, in turn, allows clients to accept our job bids with confidence that they will receive consistently excellent work, produced with safety uppermost in mind at all times.

 

 

Calvac’s safety program includes:

  • Up-to-date training on the latest OSHA and DOSH policies, procedures and protocols
  • First aid training including CPR
  • Hazard identification and mitigation
  • Workplace and job site safety and loss prevention
  • IIPP and Early Return to Work programs which allow injured employees to return to work on modified duty while remaining in compliance with healthcare provider recommendations and directives

Our insurance brokers have stated in the past that Calvac’s safety initiatives have been so successful, we are setting the standard for how safety training and associated loss prevention ought to be carried out. As we take a great deal of pride in being the benchmark for excellence in every facet of our operations, this is always welcome feedback.

The principals and management of Calvac Paving are very proud to once more be able to prove we are among the best in the construction industry at what we do. Our emphasis on proactive safety training and implementation means our employees have more productive days with a lower risk of injury, allowing them to perform at their best at work and in their personal lives. We are also pleased that our clients get to reap the benefits of our training in terms of increased production and reasonable budgets, with less potential for damaging incidents.

Construction is not an easy field in which to balance safety with productivity. However, we at Calvac are proud to show it’s not just possible; for us, it’s just the way we do our jobs, every time, every day. We look forward to continuing to prove our commitment to safety and a task done well for many years to come, working to keep our employees, clients and the general public safe as we go.

Los Altos New Private Road Project

Calvac Paving was proud to be able to serve the city of Los Altos, California by replacing a  common private road within the community. The roadway needed repair for durability, safety and aesthetic reasons, giving Calvac Paving the opportunity to once again demonstrate the quality and attention to detail of our work.

This project required some delicate handling because, as a private road in a residential area, Calvac Paving had to be mindful of residents’ access needs as well as the possibility of fires or other emergencies. It also necessitated using a special process that allowed for minimum road closure time and maximum performance. We created a short video to show the highlights of the paving process, from top to bottom.

The process Calvac Paving decided to use was a “petromat” overlay on top of the existing roadway. To do this, the failed areas were prepatched using full depth hot mix asphalt. Once this was done, the existing utility boxes in the roadway were raised up, so as to secure them against further failures in the subgrade or roadway itself. An asphalt binder and paving fabric were installed next, allowing the existing road surface to bond properly to the hotmix upon placement. A 2” lift of hotmix was placed using a self-propelled paver, and then the lift was compacted to produce a smooth, level road surface.

The finished product is much nicer-looking, offers more flexibility and durability, and didn’t require as much disruption of local traffic patterns as more traditional repair and rehabilitation projects. Calvac Paving specializes in these kinds of jobs, where tight traffic constraints and the need for access make conventional processes difficult or impossible. In this particular case, we left the property owners with a smoother, more aesthetically pleasing, better-driving roadway.

Calvac Paving has been serving the Bay Area since 1974, providing the highest-quality paving, concrete and earthwork solutions for residential, commercial, transportation and public applications. From annual budgeted concrete repairs, asphalt paving and seal coat to a complete new roadway build and striping services, Calvac Paving has the equipment, knowledge and experience to deliver excellent quality at competitive prices. We approach every job with a can-do attitude and consider carefully how to proceed to obtain the best balance of cost effectiveness, performance and safety.

 

Because our President, Jim Adam, carries CASp certification, Calvac Paving is also an ADA-certified company. This means we are continuously keeping abreast of new developments and adaptations to ADA regulatory requirements and standards. Carrying this prestigious and important certification allows us to ensure every project we undertake is in full compliance with ADA Standards as well as the California Building Code, which in some cases are even more stringent.

In addition to our certifications and awards, Calvac Paving offers a three-year warranty to qualifying customers, three times the industry standard. We stand behind every job we do with strict quality and performance standards, because we want our clients to have peace of mind that the work they get from Calvac Paving will be the best anyone, anywhere can deliver. We hold our work to the highest possible standards for materials, workmanship and durability, Calvac Paving can take pride in giving our clients/Stakeholders a finished product they can trust.

Calvac Paving is proud to have served the Bay Area as long as we have, and we will continue to do so in 2016 and beyond. Whether we’re fixing a private roadway in Los Altos or working on a major airport runway renovation, striping a parking lot or building an access ramp to the exacting tolerances of ADAS and CBC requirements, we are passionate about our work and proud of the final result.

Asphalt Crack Repair

One of the processes that paving contractors can perform in these conditions of rain and clear skies is crackfilling. It takes just a day of good weather to allow us to come in and prepare the cracks with the installation of the crackfiller the following day if necessary. Here is some information concerning this service.

CONDITION:

Linear cracking in your asphalt surface. Aged and oxidized asphalt that has intermittent cracking. These cracks are typically wide spread throughout the property and not concentrated in one area nor interlocking.
If there are alligatored areas (interconnecting cracks) then these areas should be repaired rather than crackfilled. These problems are exacerbated by the intrusion of water which will penetrate to the subgrade and accelerate cracking and base failure caused by shrink/swell of the subgrade.

Latest Paving Job Calvac Paving

CAUSE:

Causes of this linear cracking could be a less than satisfactory base course on top of a moisture sensitive subgrade causing swell and shrinkage in that subgrade. This movement reflects through the base course and the up through asphalt surface. The infiltration of moisture through this cracked and oxidized (dried out) asphalt accelerates the damage.
Additional causes would be ground slippage, expansion and contraction due to heat and cold cycles, shrink/swell of the subgrade, the advanced age and oxidization of the asphalt surface.

CORRECTION:

Cracks that are 1/4” -3/8” can be filled with a cold pour asphalt emulsion crackfiller. Cracks that are 3/8” – 3/4” will require the use of a hot rubberized crackfiller. Cracks larger than 3/4” should be corrected with hotmix asphalt, by filling the cracks with hotmix asphalt and covering with hot pour crackfiller and better yet is to follow up with a Petromat overlay of the area.
With either application the cracks will have the existing vegetation removed and then the crack will be blown out with high pressure air and high heat. If necessary we can apply a spray sterilant to the existing vegetation prior to removal.
If we apply cold pour crackfiller, then that material is poured into the crack to bridge the opening and create a flexible filler that is then struck with a specialized squeegee to force the material deeper into the crack and to localize the coverage of the material into a thin strip at each side of the crack.
If the cracks require hot rubberized crackfiller, then that material is heated to 350°+ and the material is forced into the crack and struck flush with the surface.

If your property is in need of a asphalt/concrete repair, Calvac Paving is standing by to assist!

Maintenance Mondays – Drive Lanes Removed & Replaced

Maintenance Mondays: This project was for a Medical Building. This required the crew from Calvac Paving to work on a Sunday to minimize disruption. The bulk of the drive lanes were damaged to the extent that we had to remove and replace approximately 45% of the drive lanes. The crew completed approximately 260 tons of removal and replaced with 260 tons of hotmix asphalt. All of the removed asphalt was hauled to a recycle plant. Our crews were completed and out of our yard and on their way home by 6:30pm.

5 Simple Ways To Winterize Your Paving

With winter and its accompanying rainfall on the way, the fall is a good time to take a look at your existing pavement and make sure it’s ready for the weather to come. Calvac Paving has been in the business for over 45 years, and in that time, we’ve learned a thing or two about how to solve small problems before they have a chance to become big ones. Now, we’re pleased to present this list of simple things you can watch for so your pavement lasts longer and looks and performs better in the process, even when the worst of the California winter weather strikes!

  1. Do a routine walkthrough of your paved areas.

Parking lots and other paved areas should be checked at least semiannually for problems. Things to look for include:

  • Areas of standing water. Water can break down the asphalt binder and leak down into the subgrade, eroding it over time. This is also an indication that the pavement or subgrade may already be failing, because modern grading techniques are designed to establish a grade that flushes water away from the parking area and toward designated drainage points.
  • Oil or other chemicals that leak directly onto the pavement. Just like water, some chemicals associated with vehicles can cause binder breakdown and lead to subsurface problems. Cleaning up oil and other chemical spills as quickly as possible can help prevent this and keep your asphalt in better condition.
  • Cracks, divots or uneven areas. These can be caused by weeds growing beneath the surface, freeze/thaw patterns, standing water and oil or ongoing heavy truck traffic. Small cracks and divots are often the first visible sign of possible asphalt breakdown, and it’s more cost-efficient and less intrusive to fix them when they’re small by seal coating or spot patching than it is to do a complete tearout and reinstall of the paving.
  • Striping: Old, dull or worn striping and pavement-level signage such as fire lane indicators and other information may be harder to see and read during winter months. Especially in ADA stalls, the striping and signage should always be clearly visible to make sure people know where these areas are.Recently Complete Project
  1. Clear debris from drainage channels and curbs.

If water has nowhere to go, it doesn’t matter how good the drainage plan for your lot is. Making sure the drainage channels, storm sewers and other inlets to the runoff system near your property are clear of leaves, branches, garbage and other obstructions will help the water flow better and make it less likely to pool up on your property.

  1. Limit or restrict heavy-vehicle traffic as much as possible.

Large trucks such as semis, garbage trucks and other heavy vehicles can place a lot of stress on asphalt. By itself this shouldn’t be a problem, but when the base course and subgrade are compromised by water or plant intrusion, it could speed up the breakdown process for the asphalt. If at all possible, try to limit, restrict or even out the traffic pattern for such vehicles within your lot to minimize the time they spend on your pavement.

  1. Be sure it’s sealed.

Even if your parking area is free from cracks and other problems, it is a good idea to have it seal coated every 4 to 5 years at the minimum. This is because seal coating helps rejuvenate the asphalt binder at the surface, adding an extra layer of protection against traffic, water and other spills. Even better, it will help make your parking lot and driveways look newer, especially when you redo the striping at the same time. This makes your property more attractive, safer to navigate and less likely to fail for the long haul.

  1. Seek professional help.

If you’re not sure if the paving problems you’ve identified are “big enough,” or if you think your pavement needs a facelift or a complete overhaul, Calvac Paving can help. We’ve been serving the Bay Area for over four decades with quality construction solutions including:

  • Curb and gutter remediation, repair and replacement
  • Paving rehabilitation, tearout and reconstruction
  • ADA access compliance and signage
  • And much more!

We take great pride in delivering a great product for your project, within the schedule and budget we agree upon. For more information about how Calvac Paving can help you with your  paving or asphalt project, please contact us for a no charge estimate.

Calvac Paving Obtains ADA-CASp Certification

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.

The Greenest Mile: How Charging Roads May Make Electric Cars More Efficient Than Ever

At Calvac Paving, we support technologies and construction methodologies that offer a more environmentally sound and sustainable way of creating the things we as human beings have come to rely on. From asphaltic concrete recycling to innovations such as self-healing concrete, we are always on the lookout for trends and techniques that change how we operate for a greener, healthier planet. This is why we are so excited about the possibility of roads that actually recharge electric cars as they drive! These specially designed roadways will reduce pollution, increase the performance and range of electric cars to unheard-of levels, and reduce or entirely eliminate the need for charging stations.

 

In the UK, this seeming science fiction is becoming science fact, as the government moves to experiment with charging roads. Operating on the same principle as a wireless phone charger, the roads will charge cars through magnetic induction resonance. Cables implanted in the material of the roadway generate a specialized electromagnetic field that the car can convert into usable energy. The roads will also include communications equipment attuned to the unique energy signature of an electric car, alerting the road that an electric vehicle is present and to initiate the power generation process. This will allow properly equipped electric vehicles to recharge on the go, without needing to stop for extended periods to recharge, one of the biggest stumbling blocks cited in the adoption of electric vehicles thus far.

The roads the UK are experimenting with will be restricted for the time being, ensuring that regular vehicles do not impede the testing process. The government is committing 500 million pounds, or roughly $779 million, to these experimental roads over a five-year span. This technology is already in use in South Korea, powering rail systems with ranges of up to 15 miles, and will be combined with an added initiative to provide charging stations every 20 miles in the UK. The combination of options for drivers will help eliminate so-called “range anxiety,” which one advocate described as a combination of running low on gas and having one’s cell phone be low on battery simultaneously.

Recent Calvac Paving Project

Magnetic induction resonance works in much the same way as a powerful operatic voice can shatter crystal. When the voice and the crystal reach a similar resonance, the molecules in the crystal begin to vibrate rapidly and cause it finally to break. Instead of shattering or rupturing the battery, however, the cables the charging roads utilize will create a harmonic resonance within the battery that allows it to transform the signal from the roadway into usable power.

Because many roadways contain metal in addition to the native subgrade, road base and asphalt in the form of rebar, wire-mesh matting and metallic joints between road sections, the cables can use this metal as a part of the transmission system for the power. The metal components of the electric car can be employed as a receiver, directing the transmitted energy to the battery without the driver needing to stop, handle any charging devices or worry about whether or not the car will make it to the next charging station.

Major car production companies such as Audi are leading the research into this technology, which they believe will relegate internal-combustion vehicles to the status of horse and buggy. By working together to create a standardized plug-in system for use in garages, parking structures and ultimately at-home use, these car manufacturers believe they can make charging stations easier to find and thus make electric cars more attractive. The idea of “switching stations,” where a person can simply replace a drained battery with a fresh one and continue on, and the increased range of electric cars to around 250-300 miles per full charge depending on the type of car and battery size, will help expedite this process.

While paved roads are still very much a part of the future landscape, what drives over those roads and what lies beneath them may soon play a more crucial role than ever in our environmental integrity and ability to move people and cargo. Calvac Paving will be watching the trials in the UK with a great deal of interest, because we want to see if this technology truly is feasible and what the implications will be for the paving industry. If everything pans out as the equations and scientists claim, this could be a major breakthrough and a huge tectonic shift in how things are designed in both construction and automotive industries, as well as manufacturing and transportation as a whole. We think that’s a pretty big win, and look forward to this technology here at home!

Calvac Paving Deploys Trash Capture Devices Inside Catch Basins to Combat Water Pollution

Our water is arguably the most precious natural resource we have, and it’s up to everyone to keep it clean so we always have access to safe drinking water. At Calvac Paving, we’re always looking for new ways to help keep our environment clean and healthy without compromising performance. Recently, we added a new tool to our arsenal in the ongoing fight against water pollution: full trash capture units inside catch basins.

If you’ve been walking down the sidewalk or happened to look at a storm drain in the middle of a parking lot recently, you may have noticed a marker which reads, “No Dumping—Drains To Bay,” such as a stream, lake or the ocean. Other such markers include reminders to be cautious of discarding trash and debris into water sources. All of these markers indicate places where trash capture filter devices may have been installed in storm drains.

 

The principle behind trash capture units inside catch basins is very simple. They work much like a pool filter to prevent dirt, debris, garbage and other runoff contaminants from getting into the water. Made by REM Filters, these Triton filtration systems are designed for drains which empty to stormwater repositories and water bodies. They have the advantage of being economical, flexible and relatively low-maintenance, while helping keep stormwater runoff cleaner and promoting a healthier environment.

With different filtration media available, property managers, owners and municipalities can design a custom system which works with the primary contaminants in a given area, such as streets, parking lots and garages, food courts, sidewalks and so on. The filters are easy to clean, change and service, allowing for broader application with reduced service and personnel costs versus conventional storm drain clearance procedures. Even better, Triton trash catch basins can be applied to both new and retrofit construction, saving time and money over other stormwater mitigation measures.

Calvac Paving has been serving the Bay Area for over 45 years with the latest and best in paving and stormwater mitigation technology. Some of the services we provide include:

·        New Construction 

·        Grading

·        Concrete Placement

Bay Area Asphalt and Concrete

 

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 45 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.

Latest Bay Area Asphalt Repair Project From Calvac Paving

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.
