Improve pedestrian mobility with new crosswalks, curb ramps, sidewalks, and pedestrian signalization. Replace span-wire signals with mast arm signals. Duties included contract administration; problem resolution; client and stakeholder coordination; and management of staff resources, scheduling and budget for on-time, on budget completion. This project was federally funded and cost $11.6 Million


Route 123 Bridge Replacement over Accotink Creek:

City Engineer:

Supervised design and construction of a new 2-lane prestressed-concrete beam bridge with drilled shaft foundations and a new pedestrian bridge. Both bridges are jointless and have architectural detailing that blends in with the historic downtown. The project also included construction of approach roadway, sidewalks, multipurpose trail, and landscaping. Duties included contract administration, problem resolution, client and stakeholder coordination and management of staff resources, scheduling and budget for on-time, on budget completion. This project was federally funded and cost $5.5 million.

Old Town Village:

Facilities Inspector:

This project involved the redevelopment of a 3.5 acres site in Old Town Fairfax with several mixed-use buildings with retail on the ground floor, residential units, office suits and a separate parking structure. There were issues with connecting to existing utilities which were very old and the discovery of a contaminated fuel dump on the site. The infrastructure improvements for this site was valued at 2.2 million and included the installation of storm water filters, water and sanitary sewer connections, granite curb, brick sidewalk with planter boxes, gas streetlights and relocation of utilities.

The relocation of a 36’ storm sewer and a 8” sanitary sewer which had to be rerouted to pass between the caissons of the foundation for the multi-story garage of a mixed use building to avoid a longer route through city street which would have cost several millions more.

City Hall Addition and New Police Station:

Feasibility studies were conducted to determine if the City Hall Addition and the New Police Station can both be housed on the 7.8 acre City Hall Campus. Several designs were proposed by the engineering consultants with this combination and were considered but finally it was decided that the two buildings should be housed separately with the new police station being constructed to the rear of the existing police station and the city hall addition spreading out on its existing space with at grade parking.

City Hall Addition

Facilities Inspector:

The City Hall Addition shown above involved providing 29,200 square feet, two story steel frame addition, renovation of the existing City Hall building and surface parking. Site utility upgrades, include underground storm water management detention facility, a bio-retention facility (rain garden) and two filter units, for low impact development water quality treatment adjacent to parking areas.

The challenges here were mainly logistics where some city departments had to be relocated to other city buildings such as schools and recreation centers during the course of the construction and relocated back to city hall when construction was completed. Other departments which remain at city hall had to endure some inconvenience during construction of the addition with maneuvering for parking at neighboring privately owned facilities and constant relocation of office equipment to accommodate construction activity.

The soils in the City of Fairfax is a mixture of silt, sand and clay with low load bearing and moisture capacity – compensation for these defects were made by increasing footing size for structures and pavement section for parking areas. City inspection staff was able to recommend the use of special materials which were a bit more expensive on the front end but more cost effective over time as they would avoid constant repairs to the parking lot in the future.

Police Station:​

Facilities Inspector:

The new police station shown above included a 30,800 square feet frame building with brick envelope, surface parking, utility upgrades, low impact storm water runoff control which utilize a terraced swale system and dry pond for water quality treatment adjacent to the parking areas, which would provide habitat for local wildlife while buffering the police station from a municipal park in the area.

Fairfax Regional Library:

Facilities Inspectors:

The Fairfax Regional Library shown above was a joint venture between the City of Fairfax and Fairfax County and involved the relocation of the library to a 44,450 square feet steel frame building with brick envelope and 81,600 square feet of below grade parking, storm water filters, utilities and streetscape improvements. Challenges here involved providing separation between the construction site and nearby North Street and Old Lee Hwy intersection while excavation for the below grade garage some 30 feet below street level was performed. This was achieved by constructing a retaining wall to hold the street in place while the foundation for the parking facility for the library which will sit above it were being constructed below street level. 

Fairfax High School:

Facilities Inspectors:

Fairfax High School Addition shown above involved the renovation and addition to the existing high school building providing and additional 59,869 square feet of additional floor space to accommodate the anticipated increase in the student population of about 600. Infrastructure improvements include increased parking area with bus loop, utility upgrades, storm water detention and storm water quality control facilities valued at 2.5 million.

Here city inspection staff used its experience in working with the soils of Fairfax and its particular property of becoming temporary elastic properties when wet. This was of particular concern here because most of the site work was done during a very rainy spring and summer of 2006, while pushing for completion before school reopened in September. After installing the water and storm water facilities under parking lots the problem was to achieve a stable base for the application of the road and parking areas in wet conditions.  

Lanier Middle School:

Facilities Inspector:

Lanier Middle School Addition shown above involved construction of an addition to the existing middle school, additional parking, utility upgrades, storm water management facilities and construction of a school bus lane. Demolition of a portion of the existing structure was necessary to construct the addition. The total value of the infrastructure improvements for this school was valued at 2.6 million.

Challenges here involved keeping the schools open while the upgrade of facilities and construction of the addition were undertaken. Crews had to work at nights and get class rooms ready for students by next morning. Here this logistics nightmare continued for several months while the construction progressed. Construction of the parking lots had to be completed during this very rainy summer causing problems with achieving a stable base for construction of the roads and parking areas and getting the school ready for reopening in September.  

Pickett’s Reserve, Residential Subdivision: 

Facilities Inspector:

Pickett Reserve is a residential subdivision with 89 single family homes, two-way single-lane road system, two storm water management ponds, sidewalk and curb, storm sewer systems, sanitary sewer system and portable water system. On this site there were a lot of deep sanitary and storm pipes place at about 25 feet below grade. The Facilities Inspectors had to be very watchful for the potential for cave-ins which are a high possibility when working so deep and laying back slopes. There were also two 10 inch water main connection to a 24 inch water main which were made under Pickett Road using horizontal boring with a 24 inch casing to avoid working within the traffic at street grade. Several site changes to the erosion and sediment control plans to prevent soil from leaching through several thousand feet of stone retaining wall that were being constructed.

Farrcroft, Residential Subdivision:

Facilities Inspector:

Farrcroft is a residential subdivision with 262 single family homes, two-way single-lane road system, bridge over Danial's Run Stream, pool, community center, one storm water management pond with a sediment fore bay. Construction of this wet pond required a stream diversion as the pond was constructed in an active stream.
