In northern climates, successful cold weather concreting expands contractor opportunities while meeting demanding construction schedules. Waiting for Mother Nature to fully cooperate often leads to costly delays that owners, investors and developers simply cannot afford.
However, proper planning is essential for successful cold weather concreting.
Self-consolidating concrete (SCC), also known as self-compacting concrete, is a flowable, non-segregating product that spreads into position. It fills congested formwork without mechanical vibration. It readily flows into complex shapes and inaccessible areas, minimizing voids in the process.
In every construction project, it is incumbent upon all stakeholders to evaluate it from a lifecycle perspective. A thorough lifecycle analysis reveals the many benefits of concrete.
In an era of increased environmental awareness, such considerations are even more important. In general, the environmental impact of a given building or pavement project decreases when materials last longer. Projects with shorter lifespans tend to generate waste quicker and consume more resources.
Decorative concrete gives the standard variety a serious makeover. Enjoy durability and style combined in one attractive, long-lasting surface. You'll find that the creative applications are virtually limitless. The undeniable curb appeal of decorative concrete means that a percentage of the cost is frequently recovered at resale.
Today's parking lot projects often face stringent environmental requirements regarding water runoff. There's also a frequent desire to optimize land use in a way that improves your return on investment (ROI). One of the best ways to deal with stormwater runoff is to reduce its volume through the use of pervious pavement.
Since much of Pennsylvaniaʼs exterior concrete work occurs in the summer, hot weather concreting is of real interest to contractors. Those that take the extra steps necessary to place concrete in hot weather stay on schedule, and they keep crews busy.
However, extra care is required to ensure that concrete placed under adverse summer circumstances will be strong and durable.
At first glance, the smooth, solid surfaces of asphalt and concrete driveways appear more similar than not. However, there are key differences in longevity, load-bearing capacity, convenience, lifecycle costs and resale value.
Many of Pennsylvania's bridges were constructed decades ago, a time when usage was vastly different than it is today. As a result, many bridges carry much more traffic than their designers ever intended. Since the days of the Eisenhower administration, America's vehicles have tripled in number.
The most recent National Bridge Inventory (NBI) from the Federal Highway Administration identifies 22,783 bridges in Pennsylvania. Forty percent of them are classified as either "structurally deficient" or "functionally obsolete." To rectify the situation, billions of dollars in repairs, restorations and replacements are needed.
The construction of buildings using insulated concrete forms (ICFs) offers numerous tangible benefits over wood-frame construction, including energy savings, durability, the speed of construction, reduced environmental impact and insurance savings. Also, ICF walls are effective vapor barriers, and they suppress the transmission of sound as well.
There are also intangible benefits to consider, like increased peace-of-mind for property owners, tenant satisfaction and a greater perception of value by prospective buyers.
Roller-compacted concrete (RCC) is a durable material increasingly used for parking lots and high-load applications. From intermodal yards to industrial flooring, RCC is already seen as an economical and durable solution. It is now also being used to complete a number of municipal paving projects in Pennsylvania.
The RCC process requires a stiff, zero-slump mix with the consistency of damp gravel. Rolling achieves desired densities and strength without reinforcement. A very low water-to-cement ratio often makes RCC as strong as conventional concrete. Diamond grinding is an option when a surface without roller marks and with precisely defined frictional characteristics is important.
If you are a building developer, you face a fundamental question when a multi-family project moves forward, "What type of construction do I invest in?" Hazard mitigation is one key consideration due to its impact on insurance and other costs.
Fortunately, it's possible to take a strategic, calculated approach to mitigating risk. MIT's Break Even Mitigation Percent (BEMP) Model guides decisions regarding hazard mitigation costs. In one example, a $340,000 hazard mitigation investment in a $10 million commercial structure is made up through reduced insurance premiums and other savings.
Should your new parking lot be surfaced with asphalt or concrete? There are many reasons to seriously consider concrete, from economic to environmental and from aesthetic to functional. Here are five key reasons why an investment in a concrete parking lot makes sense.
