A-2 AUGUSTA COUNTY COURTHOUSE n FEASIBILITY STUDY


Introduction:

A visual structural survey was performed on April 26, 2012 of the existing three level historiccourthouse building located at 1 Johnson Street in Stanton, VA. The purpose of the survey was to

identify and assess possible structural damage that is present in the building. The buildingmaintenance engineer, the mechanical engineers and the project architect were present during the

survey.

Procedure:

All of the items identified in this report were obtained through a visual survey. Visually

accessible areas of the building structure were surveyed in detail. Areas of the structure covered by existing architectural finishes were not observed since the structure could not be seen without

causing damage to the existing finishes.

Description:

The existing building has three floor levels including a below grade basement level. The footprint

of the original building is approximately 5,500 GSF per floor level. A three level addition totaling

approximately 2,000 GSF per floor level was added to one of the longitudinal sides of the building providing an overall GSF area of 22,500 GSF.

According to the existing structural drawings dated February, 1901, the primary floor structure of the building consists of 6-inch and 10-inch deep steel beams spaced at 4-foot 4-inches and 4-foot

9-inches on center which support a series of brick masonry arches. Two steel tie rods are used at

1/3 points along the length of the beams to provide lateral support to resist the thrust of thearches. Each beam line is supported by the interior and/or exterior loading bearing transverse

masonry walls. Our building survey confirmed the information contained in the drawings at the

visually accessible portions of the existing ceiling structure in the basement level of the building.

See Photo #1.

The roof structure is built with a series of heavy timber trusses, and beams spanning to the

transverse interior load bearing masonry walls. An intricate curved wood framed dome structure

was observed at the center of the building.

Observations:

The following items were noted during our survey of the building.

A previous repair over a 1st

floor window opening was completed last year. Weunderstand that a severe sag in the 2nd floor occurred above the window. All the repair

work appeared to be performing satisfactorily at the time of the site visit. See Photo #2.

A shoring post was observed at one of the steel beam locations in the basement ceiling. A

deflection of approximately about ¼ -inch was measured at the mid-span of the beam

which is not excessive for the span length of the beam. There does not appear to be anystructural distress in the floor structure at this location. See Photo #3.

Several of the existing floor beams where strengthening by the addition of new adjustablesteel column shoring posts. It was observed at the floor above that the high density files

were added on to the floor requiring the addition of the posts. See Photo #4. Theadditional support structure appears to be performing adequately.

During the inspection of the attic area, it was observed that several of the wood purlin

beams have twisted to the extent that the bearing length of the rafters has been reduced.The location of the rafter notch is no longer located where the rafters meet the top of the

beam. See Photo #5. Diagonal braces have been added at other purlin beam locations to

mitigate the twisting and warping that is occurring at these beam locations.

Repointing is needed at the top of both of the chimneys. See Photo #6. At one location on

the face of one of the chimneys loose bricks have partially displaced slightly from theface of the chimney. See Photo #7.

A small vertical brick crack was observed on the exterior face of the building below oneof the 2nd floor windows. See Photo #8.

The hardscape around the perimeter of the building is a very poor existing condition. Thefollowing items were noted;

1. Severe cracks and slab settlement occur at the cast-in-place concrete stair treads

and risers. See Photo #9.

2. A significant amount of rust was observed at the base of several of the steel

guard rails. See Photo #10.

3. Spalls and cracks occur at the base of the stone portico columns and curb stones.

See Photo #11.

4. A series of severe spalls has occurred on the face of the walls that wrap the

perimeter of the stairs and ramps. See Photo #12.

Recommendations:

The following remedial actions are recommended to retain the overall stability and durability of the building. This list should be considered as an initial starting point for the repairs rather than as

an all inclusive restoration list for the building since some portions of the existing structure are

not visually accessible due the presence of architectural finishes.

The two existing chimneys above the roof level of the building need to be repointed witha lime based repair mortar. All loose bricks need be reset securely within the face of the

chimney.

The existing hardscape surrounding the perimeter of the building should be removed and

replaced in its entirety. The existing sub-soil should be re-compacted to prevent future

additional settlement.

The existing exterior wall crack below the 2nd

floor window should be filled with an

appropriate lime-base repair mortar.

Lateral wood bracing members should be added in the attic structure to securely brace all

of the existing purlin beams. The existing rotated purlin beams should be reset to providefull bearing support to the existing roof rafters.

Re: Augusta County Courthouse Job No.: 12046MEP Upgrades

Please note the following regarding the MEP Upgrades for the referenced project:

HVAC System:

- Replace the boiler with a high efficiency (92%) gas fired 700 MBH input type boiler. Replacethe two large boiler pumps. The piping system with radiators is to remain. Provide twelve lowvoltage control valves with thermostats located around the building to improve thesupplemental heating control.- Remove the existing air conditioning systems and exhaust systems.- provide new toilet exhaust systems- provide new outside air ventilation system for the Basement, consisting of two 500 cfm wheeltype energy recovery ventilators and associated ductwork.- provide new 3 pipe variable refrigerant (VRF) heat pump system for the building, including thenew addition, with combination of ductless and ducted units, as follows:1. Basement zone - 156,000 btuhs of ductless split units, generally one unit in each room or
