330 Fellowship Road is a part of a four building complex that is Liberty Walk at East Gate in Mount Laurel, New Jersey.  Liberty Properties have purchased a corner of a street block containing 3 buildings.  Two buildings were demolished and three were built, including 330 Fellowship Road.  There are a pair of warehouses behind 330 Fellowship Road that will soon be purchased and replaced.  All of the land will be beautified, including miles of sidewalk for the general public to use. 

This building is a typical shell and core Office Building coming in at a little more than 25,000 square feet per floor, for four floors.  The 239ft by 114ft rectangular building has both new and old architectural features, as well as some very interesting ideas.  It will be receiving at least Leed Silver rating, with a chance of receiving a Leed Gold rating.

For roughly 3/4 of the front and rear exteriors length wise, and for 3 floors up the building has attractive brick with details and raised texture sections.  Above the 3/4 lengths and on the 4th floor it switches from brick to sandblasted aluminum, as well as making the windows larger.  However, on 1/8 of the front and rear exteriors on the ends, there is no brick or aluminum, but pure spandrel and vision glass from the ground to the top of the 4th floor.  A similar effect is produced for the two shorter sides except for a little more than 1/4 the short side length on each end being glass.

It has a very elegant entrance lobby, with perhaps an even more interesting back lobby which connects and split the bottom floor down the middle.  On the north side of the lobby, there is an atrium which the second floor balcony looks over.

The Contractor has to comply with 2003 IBC and UCC of State of New Jersey codes.  There were no zoning issues.

There were two buildings that needed to be demolished before construction could commence.  This helped to earn points in the Leed rating.  However, I do not have any plans showing how extensive the demolition would need to be.  Though the GC would be responsible for all possible recycling of materials.  There were no historical requirements that mandated the two previous buildings remain standing.

The curtain wall system isn’t too complex.  Where there are bricks, they shall be laid in front of a structural steel backer wall with a minimum 1” air gap.  An exterior vapor barrier as well as a sheathing layer will be placed on the outside of the steel backer wall.  The interior face of the panel will be insulated.  The glass will be glazed with the frames having a Duraner XL Finish.  The vision glass will be 1” thick, with another layer of 1/4" Low-E glass. 

The roof will be an energy star roof for Leed Points.  It will be a thermoplastic polyolefin (TPO) roof of a reinforced 0.60 mm thickness, on top of 6” rigid insulation.  This insulation will be adhered to the metal decking, and not pierced.  This system will provide an R value of 30. 

Primary Engineering Systems
The structural system is a pretty basic or common system.  It has a 4” Slab on Grade Foundation, with concrete edge beams around the perimeter of the building.  The bottoms of the edge beams need to be a minimum of 3’ below grade.  Below the interior steel columns are 2’ to 4’ deep from top of SOG square column footings.

Running up from the foundation are all W12 steel columns, with weights ranging from 45 to 79 with the larger columns being on the interior grid.  W18x35’s are the most common beam size, being placed where the tenants would lease.   Slightly smaller beams are used for the interior third span, being that it is smaller.  The girders on the end of the building as well as the interior longitudinal girders are bigger, from sizes W21x50 to W24x84.  This description is typical for the two other floors above.  For the roof, much smaller beams are used, as well as trusses, with the 28K6 being the most common truss.

Electrical and Lighting
The system is a standard 277 volt / 480Y volt building.  The entire building is on a 2000 Amp Service.  The Air Handling Units run off of the 480 volt service.  Because the tenant space is designed to be self furnished and finished, the electricity service is not finished.  There is a 250 KW generator Life Safety Standby in an exterior weather proof casing.

The only finished lighting resides in the two lobbies, and any common areas including elevator lobbies, and a single corridor on the second floor.  The majority of the lights in most of the common space are recessed circular fluorescent lamps.  The corridor has square 2x2 fluorescent lamps.  The sculpture in the rear lobby is backlit by 10 single line fluorescent bulbs.

Mechanical System
There is a specific Air Handling Unit per floor, with the ducts running down the chases to each floor directly down from each AHU.  Because the tenant space isn’t leased, the final diffusers or finished ducts aren’t in place yet.  The tenant will place these when it leases the space.  The cooling operation runs off of electricity, while the heating coils run off of a gas line in from the street.

Construction Systems
There is a General Contractor from Penntex Construction running the show.  I currently do not have the information of what kind of contracts were signed between the owner and GC, and the GC and subcontractors.  The building will be LEED Rated, with the most probable rating of Silver.  If Liberty Properties is lucky, they’ll receive a Gold rating.  Liberty was proud to boast of their support for the GBC and the LEED system, telling the workers that what they are doing will be good for the environment.  Liberty hopes that this will result in more productive workers as they take more pride in their work.

Fire Protection Systems
The Fire Protection is a standard system sized for Ordinary Danger Levels.  It stems directly off of a 12” water main from the street into the building.  The main feeder rises up to each floor and branches off to cover all of the floor area.  It is a standard wet system.   All of the interior exposed columns have fire proofing sprayed on.

Miscellaneous Systems
The Elevator is an Otis Holed Hydraulic LVM 3500, with a 3500 pound rated capacity each.  The telecommunications system is not currently finished, due to the tenant space not being finished.  The tenants will run the lines from the electrical rooms to where they want.
