Richard Davis, Jr. brings many years of construction experience, which includes 17+ years in tunnel construction as a Construction Management Resident Engineering Inspector and 14 years in other construction trades. I have extensive experience with tunnel inspection services as well as valuable training skills and have trained new inspectors on various projects. I am experienced in procedures involving drill and blast, rock and soft ground mining, tunnel boring and microtunnel boring machines and raised boring, standing support steel, concrete, shotcrete, grouting, rock bolting, and spiling. I was previously working on the Gilboa Dam Low level Outlet tunnel construction CM Services for NYC Department of Environmental Protection in Gilboa, NY as the Senior Tunnel Inspector until my job duties were fulfilled.

Relevant Experience

Gilboa Dam Reconstruction CM Services, NYC Department of Environmental Protection, Gilboa, NY (1/2018-5/2019) 5320.0

As Senior Tunnel Inspector, I provided microtunneling construction oversight for the Gilboa Low Level Outlet (LLO) construction. I observed and documented microtunneling activities in the tunnel, shaft, and the slurry separation plant on the surface. I oversaw quality by monitoring compliance to contract documents and shop drawings. I prepared daily reports, annotates tunnel construction progress, tracks units for monthly pay estimates, documents non-conformance work, and records data for construction as-builts. The Microtunnel is being constructed to facilitate the ability to drain the reservoir and meet proposed conservation releases. The project consists of an outlet facility that will include a new intake tunnel, an outlet tunnel, and a new valve chamber. Key features of the project include drill and blast shaft excavation; MTBM mining for a land leg to a valve chamber from a 42-foot-diameter, 185-foot-deep work shaft; a water leg tunnel to tap into the Schoharie reservoir with MTBM wet retrieval and the construction of an intake structure for the LLO at the bottom of the reservoir. The land leg is 1,208 feet long and all in rock; the water leg is 950 feet long and mixed face, starting in rock, then through till, lake bottom sediments, and finishing in tremied low-strength concrete at the approach to the coffer dam site for the intake structure.

East Link Construction Management, Sound Transit, Bellevue, WA (2017), 5238.0

I was a Construction Management Inspector on the East Link’s four Bellevue Corridor contract packages delivered utilizing DBB and GC/CM methods. The firm is providing integrated staffing and management during preconstruction and construction to owner’s CMs, which have oversight responsibility for each package. The corridor is approximately five miles long and includes six new stations, a 0.5-mile SEM tunnel, two long-span interstate crossings, roadway and utility work, and parking facilities.

Alaskan Way Viaduct SR 99 Bored Tunnel, WSDOT, Seattle, WA (2013–2017), 4441.0

I provided Tunnel Inspection Services, observing tunnel boring activities. I was responsible for monitoring TBM parameters and interpreting data in real time. I also maintained records for QA/QC verification procedures during the erection and installation of permanent tunnel support system. Other responsibilities include completing inspector daily report (IDR) and other project mandated forms and reports. I had the responsibility for safety related issues and to communicate any issues to the appropriate management personnel. The project consists of cut-and cover structures at the north and south portals; a 57.5-foot diameter bored tunnel utilizing an EPB tunnel boring machine; an interior concrete structure with stacked roadways for northbound and southbound traffic; two tunnel operations and ventilation buildings; and tunnel and traffic safety systems.

Ballard Siphon Construction Management, King County, Seattle, WA (2013), 4394.0

I was an Inspector on this Ballard Siphon Construction project. The project was undertaken by King County DNRP/WTD to rehabilitate and expand the capacity of existing twin 70-year-old, 36-inch-interior-diameter wood stave pipes, through the construction of a new tunnel and ancillary facilities.

South Cobb Tunnel, Cobb County Water System, Austell, GA (2008–2013), 4069.0

I served as an inspector for the construction of a 5.5-mile, 27-foot-diameter wastewater tunnel and associated vortex drop intake structures. The main tunnel excavation was driven using Herrenknecht TBM and used rockbolts, wire mesh, mine strap, rolled channel, and ring steel as required for initial ground support. As part of this project, five connector tunnels and chambers were constructed. The connector tunnels and chambers were excavated using drill and blast with rockbolts and wire mesh for initial support. I was initially responsible for inspecting the excavation, support lining and grouting of the launch shaft, drill and shoot for the starter tunnels, and TBM assembly and start up, I transitioned to being responsible for inspection of the multiple headings associated with the connector tunnels and chambers.

Heartland Corridor Construction Management, Norfolk Southern Corporation, Bluefield, WV (2008), 4051.0

I served as Senior Inspector on several railroad tunnels throughout the Appalachians. My responsibilities included monitoring drilling, grouting, and liner removal throughout the railroad tunnels. This project consisted of taking out the crown and widening the tunnels to allow for access by double stack rail cars. This work was performed during small windows of time, while maintaining rail traffic.

Narragansett Bay CSO, Narragansett Bay Commission, Providence, RI (2003–2008), 3350.5

I served as inspector for the construction of a three-mile, 30-foot-diameter with 26-foot-finished-diameter CSO tunnel and vortex drop structures. Tunnel excavation was by open face rock TBM with expanded segments for initial support. In addition, seven adits/chambers were excavated using drill and blast with steel rib/rock bolt initial support. I also served as inspector for construction of a pump station, CSO diversion structure, and gate and screening structure. Responsibilities included inspection of steel reinforcing installations and concrete placements, tracking jet grouting and secant pile installation, support of excavation, and inspection of construction related activities for the final fit out of the pump station building and deep pump cavern.

Prior Experience

MetroWest Water Supply Tunnel, Boston, Massachusetts (2001–2003)

I served as the Construction Inspector responsible for overseeing contact, consolidation, pressure, and chemical grouting of a five-mile stretch of concrete-lined, 14-foot-diameter tunnel. I also inspected 10-foot-diameter steel pipe installation, production welding, and tunnel and shaft concrete placements. My responsibilities included sampling and testing approximately 10,000 CY of concrete, monitoring installation of reinforcing steel, inspecting weld production for steel conduits during construction of a 280-foot riser shaft that encased two 10-foot-diameter steel riser conduits, and tracking quantities during grouting of tunnel lining.

Westside Light Rail Transit, Portland, Oregon (1997–1998)

I was a tunnel miner on a new transit extension tunnel. I worked on a three-mile tunnel section of the 11.5-mile light rail transit extension. My job duties included tunnel excavation utilizing both drill and blast techniques and a Tunnel Boring Machine. I was also responsible for placing cast-in-place concrete tunnel lining into the 22-foot-diameter tunnels using horseshoe concrete forms.

Allegheny Mine #1, Grass Valley, CA (1995–1997)

I was a miner for the Allegheny Mine Shaft, a mine consisting of shafts, drifts, raises, and stopes. I utilized drill and blast methods, supporting the ground with shoring, rock bolting, and shotcrete when needed. I also laid railroad track when advancing the mining operations.
