Purpose
C-O-A, Mixed Use District
“The purpose of the C-O-A, Mixed Use District is to encourage a coordinated mixed-use development of office, multiple-family and hotel use in the vicinity of Metro-rail stations. To be eligible for the district, a site, or a major portion of a site, shall be located within an area designated for "coordinated mixed use development" on the General Land Use Plan. Determination as to the actual types and densities of uses to be allowed will be based on the characteristics of individual sites and on the need for community facilities, open space and landscaped areas, circulation and utilities.”

Architecture
The Anderson Building is a 22-story mixed use building with 326 apartment units, 3 retail spaces, and a leasing area on a 1.25-acre site. The average floor plate for the structure is 17,000 SF and the total for the building, including the garage, is 438,000 SF included the garage. The garage consists of 5 levels of below-grade parking built with conventional reinforced concrete. The 1st floor consists of the main residential entry and retail spaces with the leasing area located on the 2nd floor. The residential units are a mix of studios and 1-2 bedroom apartments with amenity areas on the Penthouse level, which includes a workout facility, pool, shuffle board area, and lounge. Other amenities also include bike storage/repair shop and a pet spa.

Building Facade
The façade is comprised mostly of glass window wall with brick piers and composite metal panels. Some of the other items in the exterior wall system are vapor/air barrier, insulation, flashing, and drainage system. The detail below shows where the window wall system ties into the brick masonry system.
Building Roof System
The roof is a mix of TPO and paver system. The paver system is located on the pool deck area. The detail below shows the detailed section at the TPO membrane roof system.
Sustainability
The Anderson building aims to achieve a LEED Gold Rating. The Anderson Building looks to achieve most of its points through the Sustainable Sites category. The other category the Anderson building looks to achieve most of its points it through sustainable energy design.
Systems
Construction
The Anderson Building has many logistical challenges for construction. The building footprint takes up most of the site, therefore there is little to no laydown area. The site where the Anderson Building will stand has neighbors on all four sides. On the west and south there are neighboring buildings with below grade garages that but up against the site. To the north there is a main road that has a metro tunnel running beneath it and to the east there is another street that has a building adjacent it to it as well. Once excavation and support of excavation is completed, the phasing moves into concrete. For the duration of the project, their will be a tower crane in the northeast corner of the sit. The crane is provided by the concrete subcontractor, and mainly used by them, but is open for use to all trades.
Mechanical, Electrical, and Lighting
The three major components to the mechanical system are 100% Outside Air Units (OAUs), Variable Refrigerant Flow (VRF) units, and Rooftop Units (RTUs) all located on the roof. The OAUs will supply fresh air to the units in the building, the VRF units will handle the heating and cooling loads, and the RTUs will supply the conditioned air from the VRF units to the apartments. The retail space will have its own separate VRF units allowing the owner to back charge HVAC expenses to the future tenants of those spaces. The primary power, supplied by Dominion Power, will be fed into the DVP vault located on the P1 level. The building is also equipped with a 437.5KVA / 350KW, 277/480 V, 3P backup generator for emergencies. The generator will be directly supplied with natural gas. The lighting for the Anderson Building is standard for a residential building but does have some upgrades to meet the “luxury” building class. The lighting package for the units has been upgraded to include items such as under cabinet lighting, which is not a typical feature in apartment buildings. Another option that has been discussed is a lighting package for the exterior of the building.
Structural
The building’s foundation is comprised of concrete footers, while the structure is comprised of two major systems. The first system is cast in place reinforced concrete which is used below grade for the underground parking garage. The second system is cast in place post-tensioned concrete which is used at the floors above grade. The reason for post-tensioned concrete above grade is to reduce the floor slab thickness. Although costlier, it allows for a smaller floor-to-floor height which ultimately adds more floors to the building with the same overall height. Crane and bucket will be the placement method for the footers and columns while pumping will be the method for the floor slabs. The phasing plan is to break up the floor slabs into three separate areas to allow for smaller pours.
Fire Protection
For this building, there are two primary fire protection systems. Above grade in finish areas there is a wet pipe system, while the below grade in the garage it is a dry system. This is typical for most buildings. All corridors will have 2 hour rated assemblies to allow to egress to the stair towers. Each stair tower will hold the standpipes for the sprinkler systems.
Transportation
The Anderson Building will have four elevators that are classified for passenger use. They are rated for 4,000 pounds and travel at a speed of 500 feet per minute.
Telecommunications
On each floor there is an electrical and telecommunications closet that will house all the communications and data lines. The serviced provider will not be sole sourced but will have service from both Comcast and Verizon.
