Today’s modern mid rise and high rise luxury condominiums and apartment buildings offer numerous amenities to attract potential owners. They can offer spectacular vistas through floor to ceiling walls of glass, high end finishes on the floor, gourmet style kitchens with all the modern features one could ever want, and a master bedroom suite that offers a tranquil and quiet place to escape. In these building types, elevators become a necessary component for vertical circulation to access the floors. For those residences that are adjacent to the elevator equipment room or the elevator hoistway, the noise and vibration caused by the operation of the elevator can be a potential source of sound intrusion. Because today’s buildings are constructed with lightweight materials, and because there is a need to generate maximum useable square footage, sound transmission issues are compounded. All this combined can result in unsatisfactory living conditions for tens of thousands who live in condominiums or apartments.

Concrete masonry units (CMU) have long been considered the ideal backup material for brick facing; however, because of increasing installation costs, CMU backup systems have given way to metal stud backup systems. Brick veneer with metal stud backup walls, because they are a very cost effective and versatile wall assembly, are very commonly seen in today’s commercial buildings.  The original exterior metal stud wall systems of the 1970’s were simple. They consisted of metal studs at 16 or 24 inches on center, with fiberglass batt insulation having an integral vapor barrier placed in between. Gypsum board sheathing was placed on each side, and 15 pound felt paper was installed over the exterior sheathing.  This system eventually would fail and allow air and moisture to enter the building, degrading the insulation and thus the R-Value of the wall, not to mention causing other significant problems.

A building's wall system must constantly fight the invasion of rain, air, vapor and thermal attacks.The wall's ability to provide a barrier to each of these elements relies upon the use of appropriate materials, installed in the correct sequence.  There is no such thing as a perfect wall system; however, a wall system that performs with greater efficiency using new efficient materials is achievable.

Designing and Installing a Safe System
Almost every commercial and public building, whether it is an office building, sports arena, place of worship, or school building, contains a guardrail system. Guardrail systems are installed to provide safety and protection for the building occupants and are placed at or near the outer edges, of flights of stairs, ramps, landings, platforms, balconies and accessible areas of roofs. They will also be found at the perimeter edge of any opening or accessible surface, such as an open­ing for a stairway, or at a location where operating conditions require limited access to a designated area in order to guard against accidental falls.

Planning and Best Practices

The light gauge metal stud framing phase of a project significantly impacts several other trades. It is no secret that good planning and practices will achieve higher production rates and a level of quality that meets the project's specifications. Planning and layout should be the responsibility of the project foreman; however, everyone should be involved with preparing the work flow. While actual layout is underway, other production items should also be thought through.

For New-Construction Clean-Down of Contemporary Masonry Buildings

Cleaning today’s relatively new concrete masonries, like simulated stone and concrete brick, is different from cleaning clay masonry. Clay masonry can usually withstand the more aggressive cleaners needed to dissolve hardened mortar smears. But even clay masonries now vary enough in type to take particular procedures and products.

Demolition projects can range from small, simple jobs to complicated undertakings that require sophisticated and detailed planning. Site conditions can vary significantly, and there is always a degree of imprecision to the wrecking of the building itself. For typical building demolition and site improvements the most common procedure is to use heavy mechanical equipment such as wrecking balls, excavation hoes, grapples, pulverizers, crushers, and hydraulic breakers and shears. Several factors need to be considered prior to and during demolition, including the scheduling of demolition activities, protecting the site (especially important with occupied structures), and dealing with hazardous materials.

In challenging economic times such as these, we need to find new ways to create revenue. With increasing focus on water conservation and efficient irrigation practices come new opportunities. Whether it is simply offering product upgrades to current customers through the bid, or marketing to past customers with aging irrigation systems, a wide variety of efficient product solutions exist in the market today. Many of the new products available today do not require much or any effort above and beyond traditional installation practices and offer your customers a reasonable timeframe for return on investment.

The all-inclusive, load-bearing design of structural insulated panels (SIPs) offers an energy-efficient, quiet alternative to conventional wood framing methods. In recent years, SIPs have increasingly grown in popularity as builders strive to provide more durable products, use more environmentally sustainable building methods, and reduce costs. According to AMA Research, SIPs are now the fastest growing new building method on the market.

In today’s construction world, where green is the future, it pays to know about building techniques that not only count toward a green building rating but can actually reduce up-front costs. One such method is known as Advanced Framing, sometimes called Optimum Value Engineering (OVE). Advanced Framing takes a good hard look at the way we frame buildings and tries to eliminate wood whenever possible without compromising structural integrity. All of these techniques, when properly executed, comply with the International Residential Code (IRC), but you should check local codes before beginning a project.

When I began my career in the engineering/construction industry 37 years ago, erosion from construction sites was never a stated concern. None of the huge water treatment plants and wastewater treatment plants I designed had any provisions for preventing erosion or controlling sediment. The streams, lakes, and rivers downstream from my sites no doubt did a lot of natural “settling” and maybe “filtration.”
