Proactive Strategies to Restore Domestic Water in Buildings

 

Considering the current COVID-19 pandemic, buildings of various types have found themselves completely or partially inactive for extended periods of time. Given this condition, building owners, operators and managers should take precautions when restoring building occupancy   as it relates to domestic water systems.

Responsible plumbing design and various plumbing codes dictate the avoidance of ‘dead-end’ piping in domestic water distribution systems to avoid stagnant water. Stagnant domestic water creates the potential for growth of pathogens and other potentially harmful conditions. Buildings that have been unoccupied for any significant period of time can create a condition in which portions of the domestic water piping distribution system may contain stagnant water.

Common measures that can be taken to assist in delivering fresh water to the points of use throughout a facility are provided below:

  • Check with your local public health department for reopening requirements that may apply to domestic water in your facility type.
  • Survey the domestic water piping system and equipment to identify any leaks that may have developed during the period of extended inactivity. This is of particular importance for facilities with vintage galvanized piping.
  • Independently flush the domestic cold water equipment and piping system. All domestic water equipment and points of use should be flushed thoroughly and may require a review of the domestic water piping distribution system in the facility. Flushing should progress from the water service entry point towards the last point of use to ensure that all piping is adequately flushed with fresh water. . All strainers in the system should be repeatedly cleaned during flushing.
  • Drain and clean water storage tanks along with other potentially sensitive equipment throughout the domestic water system such as decorative fountains. Follow manufacturer recommendations and utilize cleaning products appropriate for domestic water equipment. Adequately flush the water storage tanks and other equipment after cleaning with fresh water. Refer to manufacturer recommendations for additional measures for specific equipment or points of use.
  • Independently flush the domestic hot water equipment and piping system utilizing a similar approach to the cold water.
  • Check the functionality of all domestic water equipment and components (i.e. pumps, heaters, storage tanks, water treatment, etc.). Change all filters utilized in the domestic water system. Exercise valves throughout the system and pro-actively replace valves that do not seat fully closed.
  • Perform water quality testing for areas of concern to identify if contaminants have developed during the period of inactivity. The confirmation of contaminants in the domestic water systems may require cleaning of the domestic water piping and the consultation of an industrial hygienist, engineer and contractor.
  • Maintain domestic hot water storage tanks at safe temperatures without creating a potential scalding hazard for building occupants.
  • Refill p-traps in floor drains, open site drains, etc.
  • Document all measures taken to create a facility standard for future reference.
  • Refer to resources such as the Environmental Protection Agency’s (EPA’s) “Maintaining or Restoring Water Quality in Buildings with Low or No Use” for more information.

Generally speaking, domestic water quality measures may not only be limited to significant periods of low or no usage. Normal facility operations can still include areas of stagnant water which should be managed as part of a regular maintenance plan. A water management plan for the facility should be created and updated on a regular basis.

Additional resources related to this topic include ASHRAE Standard 188, the CDC’s Water Management Plan Guidance, the American Industrial Hygiene Association Guideline, and the EPA’s WaterSense at Work.

Strategies to Reduce Viral Transmission in Buildings

In light of the current COVID-19 pandemic, building owners and managers have increased their interest in HVAC strategies and products aimed at reducing the airborne transmission of viruses. While current research is limited on the specific characteristics of SARS-CoV-2 and its transmission, there is sufficient research on methods to help control  the transmission  of other infectious diseases.

For example, there are several strategies and products in the market today that are intended to reduce or remove pathogens from breathable air within buildings or systems. Many of these are supported by extensive research and practical experience while others employ new technologies with less substantiated data. Common strategies and products used today include:

  • Increasing ventilation (outdoor air) rates
  • Increasing air filtration effectiveness (MERV-13 or better)
  • Installing ultraviolet (UV-C) lights
    • In central air handling equipment
    • At upper room fixtures in the space
  • Implementing Bi-Polar ionization
  • Installing local exhaust and/or ventilation supply
  • Adding local filtration

These strategies can be implemented in new equipment/facilities or they can be retrofit in existing equipment/facilities.  Strategies may also be combined to amplify their effect or to address varying needs. The right solution for your facility will depend on many factors and there is currently no one-size-fits-all solution. A comprehensive plan should be developed that is suited for a building’s specific goals at individual space levels.

The implementation of HVAC strategies aimed at reducing the airborne transmission of viruses  within buildings should incorporate the following steps:

  1. Review Options: Working collaboratively with a professional engineer or industrial hygienist; identify, evaluate, and document potential virus mitigation strategies specific to the facility and its goals. These may include permanent or temporary measures which can be deployed now or in the future and may be part of a building re-opening plan under the current pandemic.
  2. Implement: Once options have been assembled and specific strategies selected, the professional engineer or industrial hygienist should prepare detailed specifications, assist in obtaining contractor pricing and review implementation by the successful contractor.
  3. Monitor and Adjust: It is important that after the implementation of any strategy, its resulting effectiveness and ongoing performance be monitored. This may include periodic testing of particulates or continuous monitoring through the building automation system and can vary widely based on the goals and strategies identified. Where actual performance is found to fall short of the desired thresholds, additional strategies can be implemented or controls adjusted to enhance performance. This monitoring and adjustment phase should be discussed and planned for as part of the initial options review.

Additional information regarding this topic is available through a recently released  position document prepared by the American Society of Heating, Refrigeration, and Air-conditioning Engineering (ASHRAE) which provides an overview of infectious disease transmission and previous ASHRAE research. The document can be found here.

City of Chicago Implements Energy Rating System

In 2017, the City of Chicago created the Chicago Energy Rating System to improve the visibility and transparency of information required to be reported by building owners under the City’s 2013 Chicago Energy Benchmarking Ordinance.  As most of Elara’s clients already know, the Energy Benchmarking Ordinance requires large buildings located in Chicago (≥50,000 SF) to report energy use once per year, with additional data verification required every 3 years.

Under the new Chicago Energy Rating System, the first ratings were assigned between late August and mid-September 2019 for energy benchmarking reports that were due on June 1, 2019.  Now that the first ratings have been assigned, building owners will receive an initial six-month period within which they are required to post their Chicago Energy Rating Placard on site in a prominent location and begin sharing the rating at the time of listing for sale or lease.

How Chicago Energy Ratings are Assigned

Under the four-star rating system, four stars will indicate the highest energy performance while a one-star rating will indicate a poor energy performer.  Properties that have not submitted energy benchmarking information will receive zero stars.

Approximately 85% of buildings that report their data receive a 1-100 ENERGY STAR score from the Portfolio Manager energy benchmarking software.  These buildings will, based on their 1-100 ENERGY STAR score, receive between one and four stars on the four-star Chicago Energy Rating System.  Buildings with one, two, or three stars will be able to earn an additional star if they have improved by at least 10 points in the past two reporting years.

Approximately 15% of the reporting properties that are not eligible to receive a 1-100 ENERGY STAR score.  These properties will receive an energy rating based on the building’s source energy use intensity (EUI), which is energy use per square foot, in comparison to national medians for properties of similar size and type. The lower the percentile for Source EUI, the better, as a lower EUI indicates less energy use per square foot.  In these cases, the Chicago Energy Rating will be based on the following scale:

  • 1st to 25th percentile for Source EUI: 4 Stars
  • 25th to 50th percentile for Source EUI: 3 Stars
  • 50th to 75th percentile for Source EUI: 2 Stars
  • Above the 75th percentile for Source EUI: 1 Star
  • Any building with one, two, or three stars with a 10% improvement in the past 2 years earns an extra star

What Building Owners Need to Do

  • Ensure compliance with the reporting requirements under the City of Chicago Energy Benchmarking Ordinance.
  • Make sure you have received your Chicago Energy Rating Placard which were to be mailed by mid-September 2019.
  • Post your Chicago Energy Rating Placard and begin sharing – on an ongoing basis — your rating at the time of listing for sale or lease within the initial six-month grace period.

Elara’s Matt Swanson Publishes Article: “Proactive Energy Cost Reduction on the Rise in Chicago High-Rise Buildings”

Elara Engineering Associate Principal Matt Swanson, LEED AP, CEM has had the above titled article placed as the cover story in the Autumn 2019 issue of Chicagoland Buildings & Environments.

The article presents the proactive approach taken to lower energy costs at the existing 474 North Lake Shore Drive high-rise condominium building located in the Streeterville neighborhood of Chicago.  Elara’s forward-looking approach implemented over several years by the 474 North Lake Shore Drive Condominium Association resulted in a 23% reduction in relative energy costs since 2007; a savings of $127,930 annually.

Beginning with Elara’s 2008 energy audit, the building’s Condominium Association maintained a constant focus on the energy performance of their building and continuously implemented energy conservation recommendations identified in the 2008 audit report, and subsequent reports in 2011 and 2015.

Consistent with Elara’s recommended strategy, projects that addressed “low hanging fruit” such as controls and VFDs that have a short-term payback and reduce the overall load of the building systems, were implemented first.  This strategy paid dividends during a 2016 chiller plant replacement.  Reduced demand of end-user systems (e.g., AHUs, exhaust fans, etc.) from previously recommended energy efficiency projects allowed for the installation of new chillers that were smaller in capacity; resulting in both lower initial and operating costs.  The associated savings allowed the Condominium Association to fund other energy efficiency upgrades.

In total, all of Elara’s recommendations that were implemented represented an incremental cost of $900,000 with a payback of less than 10 years.  Additionally, $58,275 was obtained through utility incentive programs to assist in funding the projects as a result of the energy efficiency improvements implemented.

Elara Concludes Successful 2019 Internship Program

Elara Engineering’s 2019 Summer Internship Program  recently concluded with four future engineers gaining critical insight, knowledge, and experience in numerous aspects of the MEP industry. Developed to ensure that interns become fully immersed in a variety of project types at various stages of their lifecycle, all four college students supported Elara’s multidisciplinary engineering design teams from May to August of this year.

 

Over the course of the 2019 summer, Elara’s interns performed field surveys to document existing site conditions, assisted in the development of company drawing standards, utilized both AutoCAD and Revit to support the preparation of engineering drawings, executed basic engineering calculations, and worked directly with Elara’s engineers to meet project deadlines.  The Summer Internship Program also included a series of Lunch-and-Learns presented by Elara Principals and managers for the interns to learn about the company’s history and service offerings, gain insight into the MEPFPIT systems design process and potential career paths, and discuss numerous innovative projects completed by the firm.  At the conclusion of the Summer Internship Program, the interns toured the University of Illinois at Chicago’s newly constructed Academic and Residential Complex to review the innovative design strategies implemented by Elara and to gain further exposure to energy efficient systems in operation.

During my summer…I had the opportunity to work on multiple engineering teams on a variety of different projects.  The internship team gave us very clear directions and equipped us to complete our tasks.  I did not have one time this summer where I didn’t have an assignment to tackle or an engineer to check in with.  I have learned so much about the construction process and how engineers work with contractors to go from an idea to a physical structure.  ~RW

I was able to work alongside practiced engineers while learning various design techniques and practices in the HVAC industry.  Everyone was extremely helpful and ensured, over anything else, our understanding of the material.  ~ Ben K.

I had an awesome experience at Elara and…it was really cool to be able to work on all different projects throughout the summer.  The high school project was particularly interesting for me because I was able to spend time onsite as well as working on the drawings.  I have learned so much….  ~ Abby M.

I gained experience in Revit and AutoCAD and I enjoyed attending the Lunch-n-Learns because they provided a deeper discussion on specific topics.  This experience also improved my skills working in a team as it showed me how quickly a job can be completed.  Every employee brings a different experience to the table so there was always something to learn from them.  ~ Rahul M.

Elara is pleased to offer internships for aspiring engineers each summer with additional opportunities to engage students throughout the year. Resumes for internship consideration can be submitted to employment@elaraeng.com.

Illinois’ New Retainage Law Now in Effect for Construction Contracts

Facility Managers, Building Owners and Contractors take note that on August 20, 2019, Illinois Governor Jay Pritzker signed into law SB 1636, the Contractor Prompt Payment Act.

The Act, which became effective the day it was signed has the following requirements:

  • A retainage of 10% of the payment may be withheld from a payment under a construction contract prior to the completion of 50% of the contract.
  • When a construction contract is 50% complete, retainage withheld must be reduced so that no more than 5% is held.
  • It further provides that after 50% of the construction contract is completed, the amount of retainage for any subsequent payments may not exceed 5%.

These differ from previous requirements and generally accepted contractual standards for construction projects in Illinois which upheld a retainage value of 10% throughout the project construction until substantial completion.

All future contracts and subsequent pay applications and approvals associated with construction projects within Illinois limits must ensure these provisions are upheld.

First designed by Elara Engineering in 2009 using Building Information Modeling (BIM) and then delayed significantly by sudden, unexpected State of Illinois budget freezes, final construction of Kankakee Community College’s (KCC) Advanced Technology Education Center (ATEC) was completed earlier in 2019.  The ability to maintain project focus over a ten-year period was only possible because of Elara’s, KCC’s, and the lead architect’s commitment to keep the same core team throughout the entire duration of the project.  This long-term buy-in to the project’s ultimate completion and success was the critical success factor that made this objective possible.

State Funding Interruptions

Soon after construction bids were let in 2010, the State of Illinois froze its funding contribution to effectively cancel the project.  In 2014, State funding was re-established, and construction bids were reissued. However, immediately after completion of the new building’s concrete footings in 2015, State funding was once again frozen, and the project was suspended for the second time.  Finally, in 2018, KCC received the State’s funding portion to allow construction to proceed uninterrupted to completion in 2019.

Budget Success

Even though the building design was ultimately adjusted to accommodate (1) technology advances and opportunities to further enhance system efficiencies, (2) changes in student/faculty use habits within the building, and (3) the unavailability of previously specified equipment (e.g., production of the originally selected roof top AHUs had ceased); the project – even after ten years of inflation and incurred stoppage/restart costs – only required a less than 3.4% change order ten years after the initial design.

Technology Success

Recently awarded LEED Gold designation, ATEC earned a $133,048 U.S. Department of Commerce and Economic Opportunity incentive to alleviate project costs and uses 30% less energy than a baseline ASHRAE 90.1-2004 building.  The building features classrooms and functional, green technology laboratories; including wind, solar thermal, solar photovoltaic, electrical simulation and “roof labs” where photovoltaic cells were installed with walk-out access to enable student “hands-on” learning.

The highly innovative design includes:

  • Variable ventilation/demand CO2 control
  • A dedicated outside air system to provide fresh air at the floor level
  • A single pipe loop geothermal/ground source heat pump system for heating and cooling in lieu of a two-pipe geothermal system which reduced pipe and insulation use and material costs
  • High-efficiency lighting throughout the building with external and internal shading to help maintain a comfortable learning environment

Although the ATEC project was atypically long due to impacts and hurdles beyond the client’s control, it is representative of the strength of our client relationships and of our unwavering commitment to see any project through to completion – no matter what it takes.

Navigating Chicago’s New Construction Codes

Elara Engineering is pleased to initiate an ongoing series to inform building developers, owners and managers of the changes, deadlines, and potentially significant impacts from the City of Chicago’s new construction codes.  In this first installment, we provide background information on the new construction codes, identify important dates and highlight recent and upcoming code changes.

Background and Goals

According to a May 2019 presentation from the City of Chicago Department of Buildings, the goal of the new construction codes is “to better align the City of Chicago’s construction requirements with up-to-date model codes and standards used in other major US jurisdictions while maintaining longstanding local requirements that are adapted to unique conditions in Chicago.”

Chicago’s 2015-2021 Code Modernization Process – as the effort is called – has been broken down into three phases:

  • Phase I, which includes changes to the Conveyance Device Code and Electrical Code, has been completed.
  • Phase II, which includes changes to Administrative Provisions, Building Code, Energy Conservation Code, and Rehabilitation Code, is to be completed between 2017 and 2020.
  • Phase III, which includes changes to Fire Prevention Code, Fuel Gas Code, Mechanical Code, Plumbing Code, and (specific) Energy Conservation Code enhancements, is to completed between 2019 and 2021.

Electrical Code (Effective 3/1/2019)

Chicago’s new Electrical Code, which became effective on March 1st of this year, includes the following highlights:

The law does not apply to buildings designated “historic” or having “landmark status” (interior and exterior separately), buildings exempt from a local building code, and buildings that do not use either electricity or fossil fuel for comfort conditioning. The new Illinois Energy Conservation Code includes the following highlights:

  • IECC now addresses both commercial and residential buildings
  • Additional compliance paths have been identified including ASHRAE and performance based
  • Code officials are required to approve energy compliance in lieu of testing requirements outlined in the previous IECC
  • Lighting and lighting control including daylighting requirements have been updated and clarified
  • Mechanical equipment efficiency ratings, minimum airflows and required controls have been updated and clarified

Building Code (Effective 8/1/2020)

A new Building Code will be issued by the International Code Council (ICC) in October of 2019 and will ultimately be adopted by the City of Chicago for mandatory use as of August 1, 2020. A transitional period for implementation of the new building code has been outlined by the City of Chicago as follows:

  • Test projects utilizing the new ICC Building Code will be accepted by invitation only for permit applications within the City of Chicago during the Fall of 2019.
  • Permit applications within the City of Chicago will have the option to submit according to the new ICC Building Code beginning December 1, 2019.
  • Minimum standards for compliance with the new ICC Building Codes will be enacted and enforced by the City of Chicago during the Spring of 2020.
  • The new ICC building Codes will be mandatory for all permit applications within the City of Chicago as of August 1, 2020.

R-22 2020 Phase-Out Deadline Fast Approaching

Background
The Montreal Protocol is a global agreement with the goal of phasing out the use and production of Ozone Depleting Substances (ODS), which include hydrochlorofluorocarbons (HCFCs). To meet the goals established by the Montreal Protocol, HCFCs must be phased out by January 1, 2020; and will therefore, no longer be produced or imported into the U.S. after that date.

Although other HCFCs can be sometimes be found in currently used refrigeration equipment, the most common HCFC by far is HCFC-22 or R-22.  This refrigerant is used in existing air conditioners and refrigeration equipment including unitary air conditioners, cold storage, retail food refrigeration equipment, chillers, and industrial process refrigeration.

Many recall the first step of the HCFC phase out, which occurred on January 1, 2010 and resulted in the production of R-22 to be significantly reduced. Since the initial phase out, the cost of R-22, and therefore the cost of maintaining equipment using R-22, has become increasingly expensive. After the upcoming phase out, only reclaimed or stockpiled R-22 can be used for maintenance of R-22 refrigeration equipment. It is expected that the cost of R-22 will significantly increase with the latest phase due to limited and dwindling supplies.

Options for Building Owners and Managers
With potentially many pieces of air conditioning equipment under their care and responsibility, the upcoming R-22 phase-out deadline means that building owners and managers need to establish a viable, common-sense course of action to pursue.  Several options are available.

  • DO NOTHING NOW AND WAIT. If a unit breaks after January 2020, the repair may be cost prohibitive due to the cost of R-22. If it happens in 2019, a decision will have to be made to replace it or to invest in a repair.
  • RETROFIT OLDER SYSTEMS TO USE A NEW REFRIGERANT. In some cases, equipment owners can invest in a retrofit that allows existing equipment to use certain newer refrigerants. Because this option will not be possible for all systems, an analysis will be needed to determine its technical and financial viability.
  • REPLACE PROACTIVELY. Although the upfront cost/investment can be a hurdle, especially if multiple systems need to be replaced prior to the R-22 phase-out deadline; proactive replacement could be the most cost-effective alternative in the long run. Equipment owners can take advantage of current tax breaks and utility-sponsored incentive programs to potentially reduce HVAC equipment and installation costs.

Options Guidance and Cost Reduction Opportunities 

With expertise in energy audits and studies, master planning, engineering design, equipment identification and selection; Elara Engineering is well-positioned to identify, evaluate, and pursue a technically and financially sound R-22 phase-out option.  In addition, having procured a cumulative total of over $5MM in incentives from ComEd, Peoples Gas, and Nicor to help offset costs associated with the installation of energy efficient improvements, Elara can assist clients, when combined with applicable tax breaks, minimize R-22 phase-out costs as much as possible.

Elara Decentralizes Steam Plant Serving Northwestern University’s Downtown Chicago Campus

Elara Engineering recently completed the first of two phases of engineering to decentralize an aging steam plant serving Northwestern University’s downtown Chicago campus through the design and installation of several distributed hot water, medium-pressure steam, and low-pressure steam boiler plants.

Through its assessment and investigation to define the project scope and objectives, Elara determined conversion to hot water heating via distributed plants presented opportunities for energy and maintenance savings while the remaining steam production could be focused specifically on humidification and process loads. Locating small, high pressure process boilers in each building near process users allows for a significant reduction in energy and maintenance while limiting the low-pressure steam plant to winter usage allows the plant to be shut off during the summer. This design approach reduces energy costs but also allows for maintenance to occur during the summer when the boilers are not operational. Most heating, re-heat, and domestic hot water loads are served from condensing hot water boilers to maximize energy savings.  Other identified benefits of decentralizing campus heating include updating a large portion of existing infrastructure and freeing up additional land for future development in a highly urbanized environment.

The first phase of the project – completed in Fall of 2018 — addressed six campus buildings that primarily house classroom and office spaces and that do not require process steam. With Elara’s design, Northwestern University’s Abbott Hall, 345 E. Superior building, Rubloff Building, Levy Mayer Hall, McCormick Hall, and Wieboldt Hall are now supported by three new boiler plants. The plants in Abbott Hall and 345 E. Superior are stand-alone systems dedicated to supporting the building they are housed within; whereas, the Rubloff Building boiler plant supports Levy Mayer Hall, McCormick Hall, Wieboldt Hall, and the Rubloff Building itself.

In addition to the development of permit documents, contractor selection assistance, construction services, and functional testing; Elara reviewed applicable local incentive programs, prepared applications, and facilitated the approval process for selected incentives. To date, $129,952 of incentives have been procured for this $5.9M project.

Elara Guides Design of USGBC Certified Passive House (PHIUS+) and LEED Platinum Multifamily Midrise Supportive Building

To support the initiatives of Heartland Housing, Inc — a division of the Heartland Alliance (Chicago, IL) and a developer/manager of sustainable, innovative and high-quality affordable housing for at-risk populations — Elara provided advice, planning, and direction to the entire project team regarding MEPFP and sustainable features, including solar domestic hot water and geothermal heating and cooling.

Rethke Terrace in Madison, WI is a 36,000 ft², 4-story, newly constructed supportive housing facility with 60 studio, single-occupant units serving the formerly homeless or those at risk of homelessness. The property has 5,000 ft² of common area and office space for property management and four case workers, assembly space, a computer room, a library/quiet room, a fitness room, and a commercial kitchen for residents and the neighborhood.

With Elara’s efforts, Rethke Terrace achieved Passive House certification and a LEED Platinum designation for Homes (Midrise). Contributing design elements include wall assembly features with advanced framing details and an air-tight envelope, window heights and placement that maximize natural day-lighting, energy efficient lighting design, energy recovery ventilators, Variable Refrigerant Flow (VRF) heating and cooling systems to provide individual comfort control in units, occupancy sensors, window switches, kWh tracking, and remote building management.

Elara provided conceptual/pre-schematic design, schematic design, design development, bidding, and construction observation services. To support the project’s early planning phases, Elara performed energy modeling and building optimization based on numerous interacting effects; evaluated the most cost-effective building design; explored net-zero energy opportunities; and optimized lighting design and controls, including a detailed light level analysis, daylighting, occupancy control, and layouts to minimize energy while maximizing occupant satisfaction. A renewable energy analysis was also completed that evaluated multiple options, including geothermal, and their performance. Elara also evaluated plumbing heat recovery and rain water retention/reuse.

The HVAC system ultimately selected due to Elara’s work maximized energy efficiency and savings and minimized cost with respect to building envelope design.

Elara Summer Interns Reflect on Valuable Experience

Elara Engineering’s 2018 Summer Internship Program concluded with the participation of three aspiring engineers at varying stages of their undergraduate careers.  Developed to expose interns to numerous aspects of the MEPFPIT design industry, Elara’s program had all three individuals fully immersed and supporting multidisciplinary engineering design work from May to August.

The intern team reviewed existing building drawings and drafted them to scale, supported in the preparation of engineering drawings utilizing both CAD and Revit, performed field visits to document existing conditions and assisted in basic engineering calculations.  Throughout the summer, the interns also attended a series of lunch-and-learns presented by Elara Principal and Project Engineer teams to gain different perspectives on various roles within engineering, learn about the company’s history and discuss technical advances taking place in the industry.  The internship concluded with a tour of the Loyola University Chicago’s Lakeshore Campus to review the many innovative projects that Elara has completed throughout the campus and gain further exposure to energy efficient systems in operation.  When asked about their internship experience, Elara’s three very talented interns offered the following:

“This summer I was able to work alongside experienced engineers and learn more about ongoing projects at Elara. Everyone I worked with was very helpful and spent time to explain to me the technical aspects of the project. Having that background knowledge going into an assignment helped me develop a good understanding of basic practices involved in the industry.”   ~ Ben K.

“…another favorite thing was going onsite and learning new systems.  It not only helped to connect the dots from CAD to job site, but it also gave me an opportunity to meet other engineers working on the same project.”   ~ Rahul M.

“My favorite thing about the company was the sense of community that everyone had. What I mean by that is how the people here care about one another when it comes to the work everyone is doing. Everyone I worked with was able to stop what they were doing and provide me with the answers I needed. I was very impressed with how much I was encouraged to actually learn about what I was doing.”   ~ Bo M.

Elara is pleased to offer internships for aspiring engineers each summer with additional opportunities to engage students throughout the year. Resumes for internship consideration can be submitted to employment@elaraeng.com.

Elara Replaces Galvanized Domestic Water Piping Throughout Occupied 42-Story Condominium Building

Elara Engineering recently completed the engineering design and coordinated construction effort to replace leaking galvanized steel domestic water piping with new copper piping for an entire 42-story residential building, while fully occupied.  The large-scale project – completed under budget and ahead of schedule included common areas, hot and cold supply risers, condo unit branch piping, hot water return risers, and express risers (a total of 17 risers).

Key project factors included creative scheduling and work coordination to balance project speed and cost while minimizing unit occupant disruptions.  Working within these parameters, the project maintained water service to each unit at the end of each work day while impacting each unit for no more than 20 consecutive business days.  Elara worked closely with contractors, building staff, the condominium association board and building occupants to achieve a successful project.

The building’s risers are divided into two vertical zones that span Floors 1-22 and 23-42. One of the risers consists of express vertical risers to deliver domestic cold and hot water from the basement directly to the ceiling of the 22nd Floor, and horizontally to risers that serve Floors 23-42.  Two other risers serve the high and low zone and return hot water to the domestic hot water heaters located in the basement.

Elara recommended, further customized and then executed a three-phased project approach for this building.

  • Phase 1: An initial study was performed to identify scope, major obstacles to the project, potential project phasing, and cost estimate.
  • Phase 2: Replaced horizontal distribution piping, isolation valves, and an initial riser.
  • Phase 3 Replaced remaining piping throughout the building utilizing the knowledge obtained in the previous phases.
