Small Cell Sector Opportunities Increase in Telecom Market

Ben Youra Project Manager G2 Chicagoland

Project Manager
G2 Chicagoland

G2 Consulting Group – Chicagoland has provided its telecommunication clients regulatory compliance services for over 15 years. Over the past several years, G2 Consulting has seen increased opportunities in the small cell sector of the telecommunications market as carriers attempt to keep up with the need for increased network capacity brought on by consumers’ ever-increasing demand for data on their mobile devices.

This is a dynamic area of the telecommunications business given that the deployment of small cell networks is a relatively recent development and we do anticipate carriers devoting more of their resources to expanding their small cell networks going forward. Further, the regulatory framework (National Environmental Policy Act) in place for years to address new cell tower development must also be applied to the small cells and it isn’t always a perfect fit. To that end, we have seen the Federal Communication Commission (FCC) working to streamline the regulatory process to fit the generally lower-impact of small cells with respect to NEPA concerns. G2 is currently working with our clients and awaiting interpretations from the carrier’s legal and regulatory departments to address the most recent attempts to streamline the regulatory process offered for small cell facilities as put forth by the FCC in August.

G2 always stays in front of new developments in the small cell sector. To that end, we are looking forward to attending the upcoming Above Ground Level conference in Chicago on October 4th.  We hope to hear thoughts from the speakers as to where this sector is headed, as well as, their perceptions with respect to the recent regulatory changes and how the industry may incorporate these changes. G2 is always interested in bringing back information we can provide to our clients so they can make well-informed decisions on their projects.

G2 “Maps It Out” For Tower Owners/Carriers

Tony Poisson, Office Manager - Chicagoland

Tony Poisson, Office Manager – Chicagoland

As available tower space becomes more limited, it becomes imperative to tower owners and carriers to make the most of the existing space that is available. Oftentimes, this involves performing a structural analysis of the tower to determine its load carrying capacity and ability to support additional antenna structures. The existing foundation must be evaluated as part of this structural analysis.

What happens when the original foundation plans, geotechnical report, or as-built plans are not available? At this point it becomes necessary to perform an investigation to determine the subsurface conditions at the site and foundation type and dimensions. G2 has performed hundreds of such investigations across the United States for numerous clients including Semaan Engineering, Fullerton Engineering, Terra Consulting Group, W-T Communication Group, and all the major telecommunication tower owners and carriers.

G2 has the ability and network of drillers across the country to perform geotechnical investigations almost anywhere. Typically, our foundation investigations utilize low-strain pile integrity test methods to evaluate drilled piers. We also utilize excavation methods, as necessary, to determine foundation information. Our past investigations have also included evaluation of guyed anchor bars for corrosion below grade.

We also maintain a database of the thousands of tower sites we have worked on over the past 20 years and may be able to locate previous geotechnical reports or foundation designs, potentially saving a substantial amount of time and money required for new investigations.

G2 Chicagoland Recommends CCDD Services

Ben Youra Project Manager G2 Chicagoland

Ben Youra
Project Manager
G2 Chicagoland

Efficient Process Saves Time and Reduces Costs

Addressing soil characterization during the Geotechnical Investigation phase saves our clients time and money by certifying the soils during the early stages of the planning process. G2 recommends Clean Construction and Demolition Debris (CCDD) services to minimize additional expenses. CCDD is defined by the Illinois Environmental Protection Agency (EPA) as ”uncontaminated broken concrete without protruding metal bars, bricks, rock, stone, reclaimed asphalt, and soil generated from construction and demolition activities.”

Disposal of soils that cannot be utilized on site during grading is significantly less expensive at a clean fill facility. Analyzing soil and having certification forms in place early in the project stage helps remove potential delays and unplanned costs. Once site development begins, potential costs arise from stockpiling soils on site while waiting for lab results. These soils may then need to be disposed of at a regulated landfill.  Further, owners can utilize this information to obtain favorable pricing from contractors when their projects bid.

G2 Consulting Group reviews available environmental reports, as well as readily available information within the Illinois EPA’s databases to determine if there are significant environmental issues associated with the subject property or immediate adjoining properties.  Based on our review, we determine an appropriate number of soil samples and locations, as well as a scope for analytical testing parameters.

Soil samples are obtained during drilling operations performed in conjunction with our Geotechnical Investigation using proper environmental sampling protocol. Soil at the project site is visually assessed and screened in the field using a photo ionization detector (PID). Soil samples are selected for analytical testing based on visual observations, PID screenings, or using other pertinent data from our review.  Representative samples are selected and submitted to an accredited laboratory for analysis and comparison with the Illinois EPA’s “Maximum Allowable Concentrations of Chemical Constituents in Uncontaminated Soil Used as Fill Material”.  This analysis is used to determine if soils at the site meet the Illinois EPA’s criteria for disposal at a CCDD facility. Provided the material is determined to be non-impacted, a licensed Professional Engineer completes the Illinois EPA Form LPC-663 certifying that the soils are non-impacted.  It should be noted that final acceptance of the material is up to the individual landfill facility.

Smart. Results. Fast.

Unique Shaft System Facilitates Rehab of Interceptor

Jason Stoops, P.E Ann Arbor Office Manager

Nicholas A. Berkholz, EIT
Project Engineer

The Oakland-Macomb Interceptor Drain (OMID) is a 50-year-old concrete system bordering Oakland and Macomb Counties in southeast Michigan. Authorities targeted more than seven miles of this large diameter interceptor sewer – 40 feet below a busy county road (M 59) – as a priority for evaluation and repair to avoid catastrophic failure.  This project is part of a $160 million effort that has been under construction since 2009.  Given the unique opportunity the project afforded to have access to this critical trunk sewer, the owner’s objective was to perform as many repairs possible.

Lanzo Trenchless Technologies was selected to  provide multiple rehabilitation services, including  high volume sewage control management, cementitious grout in place liners, fully deteriorated model CIPP, large bore spot repairs, cementitious grouting of voids, access manhole restoration, localized crack/failure repairs using chemical grout and CCTV.  Challenges included working in and around flow that could not be disrupted during the construction process.  Work was difficult and dangerous, and required extreme care in safety consideration, monitoring and management.

One of the first tasks of the project was to tunnel a shaft down to the 96-inch diameter sewer crown, create access and build a platform for staging of both the chemical and cementitious grouting activities within the pipeline. Lanzo retained the services of G2 Consulting Group to design two 16-foot diameter corrugated steel liner shafts to gain access to the existing sanitary interceptor approximately 20 to 25 feet below ground surface.  To meet project requirements, G2 designed a shaft system that is uncommon for this part of Michigan.

New FedEx Facility @ Former Detroit Artillery Armory

Chris Nicol, PE/Project Manager

Chris Nicol, P.E.
Project Manager

FedEx Corporation will occupy a 300,000 square foot distribution center currently under construction on the former site of the Detroit Artillery Armory in Oak Park, Michigan. The property had included a 494,000-square-foot building that was a machine gun manufacturing plant during World War II, which has been demolished. The property then was turned over to the Michigan National Guard after the war for training and storage until the early 1990s, and then just for storage until 2000.

G2 Consulting Group was retained by Giffels Webster to perform a geotechnical investigation on the 60 acre site, which had varying depths of fill remaining from former uses. G2 characterized subsurface materials and developed deep and shallow foundation designs for consideration. After reviewing options, Scannell Properties, the construction developer, decided to remove and replace existing fill and construct shallow foundations. G2 now is working with Scannell Properties to perform QC during construction for earthwork, foundations, pavements, floor slabs and structural steel.

Historic Park Avenue Hotel Imploded

G2-49

Mark Stapleton, P.E.
Project Manager

The demolition of the Park Avenue Hotel was the first implosion of a structure in downtown Detroit since the Hudson’s store in 1998.  The tricky part of the Park Avenue Hotel implosion is that it is situated within the new Red Wings Arena project site.

G2 designed several earth retention systems to facilitate the required excavation which extends to as much as 48 feet deep.  One stretch of earth retention bordered the existing Park Avenue Hotel so that excavation could take place adjacent to the hotel.  When the decision was made to use implosion techniques instead of traditional demolition methods, stability of the earth retention system during the seismic event was considered.  G2 modeled the implosion using earthquake engineering and estimated that the earth retention system would be stressed but not to failure.

The result of combined effort resulted in rapid demolition of the hotel by implosion and an earth retention system that survived that event.

Future Home of the Detroit Red Wings

G2-49

Mark Stapleton, P.E.
Project Manager

Construction of a new indoor arena for the Detroit Red Wings in Downtown Detroit has begun, and G2 Consulting Group is a part of the multitude of design and construction professionals contributing to this marquee project. The new arena will hold over 20,000 spectators, cost $450 million to construct and feature a unique, glass-roofed concourse connecting it to offices and shops surrounding it.  The arena is a key part of the new, $650 million sports and entertainment district that will include mixed-use neighborhoods with new residential and retail outlets.

HOK is designing the new center, which will house retail outlets, the arena’s box office, and the offices of the Red Wings built outside the arena.  A glass roof will be erected between the buildings and the arena itself, forming an indoor “street” that will serve as the arena’s concourse and will remain open year-round, even when events are not occurring inside.

The ice surface in this eight-story arena will be built 40 feet below street level.   Working with Hardman Construction, subcontractor to lead contractor Barton Malow-Hunt-White, G2 is responsible for design of the earth retention systems for this massive excavation. Because construction is occurring in an urban environment, protection of underground infrastructure is critical, including the foundation of a 14 story historic hotel (currently vacant).

All eyes are focused on meeting the project deadline:  drop of puck for the 2017 hockey season.  After receiving official notice to proceed in late March, G2 completed their initial design submittal one week later – even as other design details were continuing to be finalized.  Following extensive analysis of geotechnical data, G2 proposed conventional earth retention systems to maintain bottom stability of this 500 foot by 600 foot area – a creative solution in this case that is far less expensive and accelerates the schedule.

G2 is very proud to be a part of the professional design and construction team for this iconic Detroit project.  Our staff is committed to doing whatever it takes to help construction go smoothly and efficiently.

Aging Infrastructure = Engineering Challenges

G2-49

Mark Stapleton, P.E.
Project Manager

G2 Consulting Group is assisting in the rehabilitation of two very different dam facilities with a similar need:  they were constructed decades ago – one over a century ago – and time has taken its toll.  Both facilities require attention to maintain their integrity.

Washago Pond Dam, Wayne County MI

Constructed in 1979 and owned by Huron-Clinton Metro Authority, Washago Pond Dam is an earthen, gravity dam. Eleven feet high and 200 feet long, the dam created Washago Pond from the Reagan Drain River.

Washago Pond Dam 12_Upstream Slope_121914Washago Pond Dam 2

G2 is assisting Applied Science Inc. and the Huron-Clinton Metropolitan Authority  in the rehabilitation of Washago Dam.  The outlet culvert is showing signs of distress, and G2 performed investigations to evaluate the condition of the earthen embankment, the culvert, and the headwall next to the culvert.  These investigations point to hydrogeological problems:  water appears to be flowing around the outside of the outlet, causing erosion.  G2 currently is developing geotechnical recommendations for repair and stabilization.

Moores Park Dam, Lansing MI

IMG_4596Moores Park Dam was constructed in 1904 and is owned by Lansing Board Of Water and Light. Located on the Grand River, Moores Park Dam is used for hydroelectric power and recreation, among other things.

G2 is assisting Stantec Consulting Michigan and the Lansing Board of Water and Light in the rehabilitation of Moores Park Dam.  Stantec has determined that portions of concrete in the dam need to be replaced, but the dam must continue to function during repairs.  G2 is designing a system to create dry conditions to facilitate concrete repair.  This system will include steel sheet pile cofferdams with water tight connections on the upstream side of the dam, and portable dams for the downstream side.  G2 will provide critical interface with the contractor as means and methods are developed.

Retaining Wall Design is “Jig-Saw” Solution

Noel J. Hargrave-Thomas, P.E. Principal/Project Consultant

Noel J. Hargrave-Thomas, P.E.
Principal/Project Consultant

 

Construction of the much-needed new 400,000-sq-ft multi-level parking garage at the Veteran Administration’s Puget Sound Healthcare System was chugging along right on schedule until the hospital’s design team unexpectedly had to change the interim grading plan. The change threatened both the schedule and budget of the project and required a total redesign of the temporary earth retention wall.20140630_112251Working with our partner on the project, Malcom Drilling, our team was able to redesign the entire system to accommodate the new site conditions using the materials that had been fabricated for the original temporary wall design. We did it in a five day design marathon. It was like solving an engineering jig-saw puzzle on the fly.

By incorporating the already fabricated system components into the retaining wall redesign, G2 was able to help minimize additional earthwork, materials costs, and construction delays on the multi-million dollar project. As a result, the project was completed on time and on budget.

We promise ‘Smart. Results. Fast’ at G2. The Puget Sound project is a textbook example of delivering on the promise.  Read more about project details.
