Over the next two decades, energy consumption is expected to increase by 30%, according to Oil & Gas Journal, meaning the need for better energy efficiency is necessary to keep up with our power-dependent lifestyles. To move towards a more energy-efficient future, corporations need to measure how effectively their electricity usage is through power factor.


Power factor is the ratio between the real power (what is used for heating, lighting, etc.), reactive power (what is pulled to create magnetic fields) and the apparent power (real and reactive power combined) consumed by an alternating current (AC) electrical system.

Power factor measures how efficiently electrical power is converted into useful output. Ideal power transmission is 100% efficiency or a power factor of one, anything less means that additional power is needed to achieve the same task. Unfortunately, a power factor of one is nearly impossible to sustain. Electrical devices connected to a network may use or produce power, causing variation in the power factor. If the variation isn’t corrected, higher currents are pulled from the network which can lead to:

Major causes of poor power factor are inductive loads on equipment. Inductive loads resist changes in current and create lag.


Adding power factor correction capacitors to the electrical system is the simplest way to improve the power factor. These capacitors act as reactive current generators, which help to offset the non-working power used by inductive loads and improve the power factor. Capacitors are cost-effective, easy to install and the return on investment is typically achieved within one to two years of usage.


The power distribution system in a network can be overloaded by excess current. Improving the power factor can offer many benefits, including:

Denver is flourishing. Its population and employment growth are among the strongest in the nation, with the population almost tripling since 2000, according to the Denver Business Journal and the Downtown Denver Partnership. To accommodate the population and business growth, nearly $2.5 billion is currently planned or under construction in Metro Denver.

Steady Construction for the Foreseeable Future

Collecting accolades from Forbes as the best place for business and careers, and with U.S. News and World Report declaring Denver as the best place to live in the country, it’s easy to see why companies are flocking to Colorado. The city’s rapid growth means its infrastructure must quickly expand as well. New buildings have to be built and older buildings have to be renovated to keep up with the office and living space demand. In turn, construction project schedules are extremely tight with little room for error.

The structural support for these new and renovated buildings must be sturdy and stable as they are being constructed in the densely populated downtown area with heavy vehicle and pedestrian traffic. Developers and owners rely on contractors to hire experienced project teams to fabricate and install high-quality products to construct these buildings on a fast paced schedule.

Structural Steel is the Material of Choice for Commercial Construction Projects

The American Institute of Steel Construction says structural steel is the trusted material of choice for many reasons:

  1. Project Schedule: Prefabrication in a fabrication shop increases productivity allowing for rapid erection on-site and a decrease in wasted materials.
  2. Construction Budget: Steel costs 5 – 7{daeb8d662f58e4975bc93960761d671bdf0aa2ad049ea8a375d2717d280ef80b} less than concrete framing. Today, a single ton of steel requires less than one single man-hour to produce.
  3. Aesthetics: Steel is functional and unique, with natural beauty, allowing for creative designs. Exposed steel emphasizes strength and transparency.
  4. Design: Building Information Modeling (BIM) allows full integration between analysis, design, detailing and fabrication. BIM applications like Trimble are taking steel design to a new level.
  5. Sustainability: Structural steel is the most recycled material on the planet and can be reused without additional processing.
  6. Modifiable and Efficient: Steel can easily be modified or strengthened depending on requirements. It also optimizes building space efficiency through the use of columns and beams that allow for longer spans of open space.
  7. Reliable and Predictable: Structural steel is fabricated under controlled conditions using quality control processes. Its strength is verified at the point of production, not after the material is installed.

Industry Knowledge and Proper Training Create a Reliable Project Team

Safe erection of structural steel requires a knowledgeable team. Ensuring workers are qualified, suitably trained and have sufficient experience to perform work safely must be established and verified prior to starting work. The steel team should be in constant communication with the general contractor and other trades to plan site access, equipment needs and laydown requirements. In addition, developing site-specific work instructions and safety procedures to identify potential risks is key.

RK Steel is currently working on several projects in downtown Denver including Bock A, 17th and Wewatta, 1709 Chestnut, 14th and Lawrence, Denver Club Renovation, Helen Bonfils Theatre Renovation, Denver Center for the Performing Arts Galleria Rails, Confluence Park Tower, 1201 Auraria and the Residence on Cherokee. RK Steel is a single source for fabricating and installing any type of structural steel or miscellaneous metals such as stairs, rails, platforms and canopies.  Do you have a project that needs a trusted, premier steel contractor to get the job done?

The healthcare field is vast and frequently progressing. As death rates decrease and life expectancy increases, people are living longer creating a demand for new and updated healthcare facilities. Thankfully, prefabrication has allowed healthcare facilities of all sizes to be built in record time.

According to The 2015 SmartMarket Report on Prefabrication and Modularization published by McGraw-Hill Construction, contractors believe that prefabrication can decrease project schedules by four weeks or more. In addition, 65 percent of contractors believe that prefabrication leads to a decrease in budget and, because of that, more than 49 percent of healthcare projects now incorporate prefabrication.

Mechanical contractors are capitalizing on this approach and are experiencing great success. Prefabrication has proved to increase efficiency through less wasted material and improve the speed of construction. Repetitive processes lead to consistency and fewer mistakes, leading to better quality products. Prefabricated mechanical systems, specific to healthcare facilities, include bathroom components or whole bathroom pods, MEP racks, wall systems and exterior elements. As prefabrication advances, new applications include modular mechanical rooms and patient and exam rooms.

Prefabrication creates safer working environments for employees. Prefabricating mechanical systems in a controlled environment means that as little as 20 percent of work is done on-site, reducing health and safety risks. And, more than one third of McGraw-Hill survey respondents using the approach say they have seen safety improve company-wide. Weather is not an issue and ladders and platforms are rarely needed. Fabrication in a warehouse and installation onsite allows multiple construction activities to be performed in parallel. According to a recent article published by Sourceable, between 60 and 90 percent of the prefabricated portions of healthcare facilities are assembled off-site.

Prefabrication is essential for operational facilities. Construction crews are able to perform work and install systems with less congestion and disturbance to facility employees and patients. Cutting down the construction schedule is also a key benefit because the sooner construction is finished the sooner they can expand the amount of care that they are able to give.
