Cooperative purchasing is a contracting option for public agencies, such as educational facilities (K-12 and higher ed.) and non-profits, to purchase equipment, products and related services without going through the time-consuming public solicitation process. Contracting agencies (Coops) such as the National Joint Powers Alliance (NJPA) conduct a competitive solicitation process of vendors (for equipment, products, etc.) and once awarded, the vendor is contracted with the Coop at set unit prices. The Coop has already conducted the required competitive bidding process. Once a member of a Coop, schools or other public agencies can purchase from vendors at the contracted unit price, without having to put in the time/effort to conduct their own public bid process.
Cooperative Purchasing can be used by schools and towns to purchase synthetic turf and infill (materials) for athletic field installations, including running track and tennis courts. Municipalities are permitted to request a quote directly from the various coop contracted vendors for their specific products. Using this purchasing mechanism, public sector clients may save money as the costs for various products are often less than when publicly bid. This also allows the municipality to purchase the exact product they want (i.e. turf and infill) rather than settle for a product that may meet a more general public bid specification.
1. Establish membership with a Coop, at no cost.
2. Review Coop’s Contract Directories to view the list of awarded vendors available. (example: NJPA)
3. Contact the vendor directly, letting them know you are interested in using their Coop contract. (Vendors will then provide you with a quote in accordance with their Coop contract and their pre-established pricing).
It was recently announced that the 9th Edition of the Massachusetts State Build Code will be released in August or September 2017. A concurrency period will be provided in which a building can be permitted under either the current 8th or the new 9th edition. This concurrency period will end January 1, 2018 and all projects permitted in 2018 will be required to comply with the 9th edition.
The new, 9th edition code is based on modified versions of the following 2015 codes as published by the International Code Council (ICC):
- The International Building Code (IBC)
- International Residential Code (IRC)
- International Existing Building Code (IEBC)
- International Mechanical Code (IMC)
- International Energy Conservation Code (IECC)
- International Swimming Pool and Spa Code (ISPSC)
- Portions of the International Fire Code (IFC)
The 9th edition brings changes to the building enclosure as well, including but not limited to the following:
- Updated code requirements for location of vapor retarders
- Vegetated roof has been defined
- Load requirements for snow drift load
- Dead load and design requirements for solar panels and support framing
- Provisions for addressing impact loads from elements supporting facade access equipment
- Seismic requirements for ballasted PV solar panels

The Federal Aviation Administration (FAA) requires all recipients of federal financial assistance exceeding $250,000 in a federal fiscal year (FFY) to create and implement three-year Disadvantaged Business Enterprise (DBE) Programs. These DBE Programs are intended to promote and enforce equal opportunity for disadvantaged firms that compete for airport contracts.
FAA New England Region DBE Programs (FFY 2018-2020) are due on August 1, 2017 and require data collection and analysis to develop goals for DBE participation for upcoming projects. DBE participation goals are calculated based on three major components:
- Available businesses in an airport’s market area for each required area of work (e.g., environmental consultants, paving contractors, or electrical contractors)
- Available DBE businesses in an airport’s market area for each required area of work
- Historical DBE participation data (airport-specific)
The FAA requires approval of DBE Program goals prior to granting federal funds. Below are some helpful resources for FAA DBE Program development:
Running tracks are a paved-in-place system. The base, comprised of a single-compound polyurethane binder and machine-installed SBR rubber granules, is what gives a track its “cushion.” After this step is complete, the track is finished with multiple spray applications of 100% solid pigmented polyurethane and EPDM granules, or an environmentally friendly water-based structural spray.
There are several environmental advantages to using a waterborne structural spray instead of a urethane based spray:
- Low to zero VOCs
- Made without isocyanates
- Reduced chemical exposure
- Reduced odors
- Faster dry times – two sprays in one day
- Less prep work and issues with clean up
- When replacing the track, the reduction of harmful chemicals allows for simpler disposal due to reducing hazardous and environmental liabilities
Many tracks are constructed on land adjacent to environmentally sensitive areas. Choosing a waterborne structural spray for these conditions is appropriate to enhance environmental protection and alleviate concerns about potential chemical exposure.
During a recent Gale track project (photos shown to the right), the town chose to use a waterborne structural spray because of the track’s adjacency to wetlands, a perennial stream, and close proximity to residential neighborhoods.
What is EIFS?
EIFS is an acronym for Exterior Insulation Finish System. EIFS is a non-load bearing, exterior wall cladding system that consists of continuous insulation board attached either adhesively, mechanically, or in combination, to exterior sheathing, which is covered with a reinforced base coat and textured protective finish coat. There are two types of EIFS: the Face-Sealed System and the Drained System. Face-Sealed EIFS is a sealant dependent “barrier system” that is fundamentally flawed due to its reliance on perfect workmanship and material performance to provide a 100% moisture barrier. The Drained System, predominantly used today, includes provision for drainage of moisture via flashings and open vertical planes between the exterior sheathing and the insulation board. This system helps to manage moisture that may enter the wall cavity. EIFS was first developed in Europe and was introduced to the U.S. as an energy-saving building system on commercial buildings in the late 1970s and residential homes in the early 1980s. The EIFS Drained System was introduced in the late 1990s.
Issues with Face-Sealed EIFS
Commercial and residential buildings constructed between the late 1970s and the early 1990s that have Face-Sealed EIFS cladding could potentially have one or more undesirable conditions caused by bulk water intrusion combined with
inadequate wall drainage. Water trapped within this wall system can cause further issues when combined with HVAC deficiencies. Defects can include microbial growth, staining of interior finishes, reduced structural integrity (corrosion and/or decay of load bearing walls), insect infestations, increased interior humidity, and cracking of the interior and exterior finishes. Although these issues are often readily apparent, decay and corrosion can be concealed and may result in latent structural damages.
The noted defects are typically exacerbated at building walls that are not periodically maintained. One of most common causes of moisture intrusion through Face-Sealed EIFS are deteriorated sealant joints and window systems. It should be noted that the service life of most windows is less than 40 years, and the service life of most sealants is less than 15 years. This implies that buildings constructed with Face-Sealed EIFS likely have windows that are approaching the end of their serviceable life, and that replacement of exterior wall sealant joints should have occurred at least twice during that time.
s (microbial growth), and the loss of revenue associated with the construction and abatement (which may include temporary relocation of tenants). If your Face-sealed EIFS clad building has deteriorated exterior sealants (typically crazed/cracked appearance) and/or interior staining/mildew odor, an assessment by an industrial hygienist, building enclosure consultant, structural engineer, and possibly a mechanical engineer are recommended. The assessments should be followed by a structured plan to make necessary repairs and replacements, and periodically (typically every 5 to 7 years) evaluate and maintain the exterior wall and fenestrations.
Deferred maintenance of sealant joints and windows in Face-Sealed EIFS can result in significant construction costs to repair or replace the EIFS, interior finishes and windows, the abatement of hazardous material.
To maintain the aesthetics of a new roof design, building owners often choose to conceal their rooftop mechanical equipment with screen walls. Screen walls are considered “architectural walls,” and are typically constructed using steel frames and finished with metal wall panels.
While aesthetics are an important consideration for screen wall design, building owners and designers should not overlook wind loading while selecting metal wall panels for their screen wall. Metal wall panels are often secured to a solid substrate, such as a masonry wall; however, wall panels attached to exposed steel framing (vertical posts and horizontal channels) in screen wall applications typically leave the back side of the panels open and exposed to wind. Wind can create a negative pressure acting outwards from behind the panel. This wind load pressure can cause panels to bow, allowing the connection between panels to disengage. When selecting metal wall panels for a rooftop screen wall, consider the following parameters:
- Panel Width: Increasing the width of a metal wall panel increases the surface area on which wind loads are applied. Selecting narrower metal wall panels helps to mitigate the effects of negative wind loading pressure.
- Panel Material: Many manufacturers offer metal wall panels in a variety of materials including aluminum and steel. Thicker gauge material with higher tensile strength will reduce the tendency for panels to deform under negative pressure.
- Panel Profile: Metal wall panels come in a variety of profiles: panels typically consist of two engagement legs on either side of the panel that interlock to form a connection between adjacent panels. Panels with longer engagement legs will provide for a deeper connection between adjacent panels, limiting the possibility of this connection to be compromised under wind loads.
Installing metal wall panels on a rooftop screen wall can improve building aesthetics; however, without proper consideration of wind loads, these panels are susceptible to damage. Selecting metal screen wall panels of an appropriate width, material, and profile to withstand wind loading pressure will help the panels to remain secure throughout the life of the roof.
In today’s health-conscious and eco-friendly world, the popularity of organic products is on the rise. This interest and concern has carried over to Athletic Facilities Planning. Gale recently completed a project for a school opting to use organic infill for two new synthetic turf fields. The school was focused on the fields’ proximity to wetlands, as well as the health of their students and the perceived concerns associated with SBR crumb rubber. The school was provided with a summary of alternative infill options and Geofill, a coconut/cork and sand mix, was selected.
The School District felt this decision was appropriate after weighing the pros and cons of the infill options and costs. Below are some considerations for organic alternate infills:
- Organic and environmentally friendly.
- Retain water, which provides an evaporative cooling effect as compared to fields with a crumb rubber infill. This can be an advantage, especially in warm climate locations.
- Provide athletes with a natural feel under foot.
- Shock pads provide a consistent G-max (acceptable impact level).
- The cost is higher compared to traditional crumb rubber field (40% increase for infill and shock pad).
- Can require more maintenance than crumb rubber.
- Requires replenishing every 2-3 years.
- The material is not recyclable for infill use, but can be used for landscaping beds.
- May require watering since it can become dusty during a dry summer.
At one time or another, every building owner will deal with the process of replacing their roof. While this is a necessity for the proper function of a building, it can often be costly, disruptive (smelly and noisy), and messy. If your building currently has a metal roof that needs replacement, one option to consider is a metal roof overlay system.
The most common metal roof overlay system includes prefabricated sub-purlins, which are z-shaped structural members that are factory cut to fit snugly over a variety of metal panel profiles. The purlins, typically 16-gauge galvanized steel, are attached through the existing metal roof panels to the building’s structural frame to provide the appropriate base to which the new metal panels are secured.
The benefits of a metal-over-metal retrofit roof system include:
- Reduced costs and disruption associated with demolition, and provides better protection for the building’s interior finishes from unpredictable weather versus removing the existing metal roof.
- Minimized requirements for the contractor to gain interior access, which reduces interruption of occupant day-to-day activities.
- Increased energy efficiency. The sub-purlins can be formed to customized depths to allow installation of additional insulation.
- Reduced labor costs from faster project completion.
- Ability to easily upgrade an existing exposed fastener (face fastened) metal roof to a more watertight standing seam (concealed clip) roof.
There are many factors to consider before choosing a sub-purlin retrofit system. The existing building structure should be analyzed to verify that it can safely support the additional weight of an overlay. Furthermore, applicable code requirements should be researched to determine if the new overlay system will be compliant. Lastly, the overall condition of the existing metal roof system and insulation assembly should be evaluated. If the existing panels are visible from the interior and are aesthetically unpleasing, or if the need for continuous insulation is driving your roof project, an overlay may not be the right option.
When planning an athletic facility project, it’s important to keep in mind the overall project timeline. Prior to bulldozers and excavators moving dirt, an engineering process that can take months to complete must occur. While each project is different, below is a typical project process and timeline:
The FAA is offering a $500 rebate to general aviation aircraft owners to aid in the cost of Automatic Dependent Surveillance – Broadcast Out (ADS-B Out) equipment. Starting in 2020, this equipment will be mandatory for flying in most controlled airspace.
The ADS-B Out requirement is part of a transition from ground radar and navigational aids to precise tracking using satellite signals. The equipment periodically broadcasts an aircraft’s position, velocity, and other information including dimensions. Displays utilizing ADS-B Out are capable of showing other aircraft in the sky or on the ground at an airport. It can also provide pilots with information on hazardous weather, terrain, and temporary flight restrictions. Only certain features are required by the ADS-B Out 2020 mandate. Title 14 CFR §91.227 defines the equipment requirements.
The FAA plans to issue up to 20,000 rebates on a first-come, first-serve basis for up to one year. This incentive is only for registered, fixed-wing, single-engine piston aircraft. Software upgrades to existing equipment are not covered by the rebate. For additional information on rebate eligibility, equipment installation, and to reserve and claim a rebate, visit http://www.faa.gov/nextgen/equipadsb. A full description of the airspace covered by the mandate can be found in Title 14 CFR §91.225.
