Architecture
This core and shell renovation project consists of significant changes to both the exterior and interiors of the existing building at 10 Schilling Rd. Perhaps the most noticeable of these changes is the entirely new façade system which will modernize the formerly outdated appearance of the building. At the center of the building a new seven story atrium will be created stretching from the ground floor up to a skylight. This atrium in conjunction with the curtain wall façade will provide more natural lighting for the interior work spaces.
A modified bitumen membrane will be utilized for the typical roof areas of the project. The roof terrace and green roof require additional barriers and drainage layers which include hot applied waterproofing to ensure the areas properly drain and are watertight. Typical roof details can be seen below.

Building Enclosure
The McCormick Headquarters building is to include a completely new façade system which consists of a curtain wall that will wrap the entire exterior of the building. In addition to the new curtain wall some locations on the ground floor and penthouse areas will include a terra cotta façade.
A LEED Gold certification is currently being pursued by the project team at the McCormick Building. Some of the strategies and technologies being utilized to achieve this rating include: significant building reuse from the existing structure, a green roof structure, a high efficiency irrigation plan, and the use of regional materials.

Construction
The McCormick Spice World Headquarters is a design-bid-build project which will be completed in the fall of 2018. A Guaranteed Maximum Price contract of $64,000,000 was awarded to Gilbane Building Company to begin construction in the fall of 2016. The current site was formerly the location of an office building for the Verizon Wireless Company. This project enjoys the luxury of a significantly large site which allows for ample lay down areas and on-site construction offices.
In order to install the additional structural framing both on the new and existing structures a mobile Manitowoc crane will be utilized with a boom length of approximately 180 feet. To transport other materials a material hoist is located on the northeast corner of the building which provides access to all seven stories.
Construction will follow a sequence of work which begins at the top floor of the building and finishes on the ground level. This unique top-down schedule is primarily driven by the atrium demolition process which must begin at the highest floor and continue downwards. To complete the interior finishes work in the atrium an extensive scaffold system will be installed for ease of access and increased worker safety.
The electrical system which is primarily located in the electrical room on the northeast corner of the first floor includes four 3000KVA transformers and an 1875KVA standby generator. Power is provided to the building via a 15kV utility distribution. The four transformers feed two 4000A switchgears which provide power to four automatic transfer switches and two distribution panels. Each floor of the building will house two electrical rooms located on the east and west sides of the building which house transformers and panel boards for their respective zones of the building.
Electrical
Lighting
A vast majority of the lighting to be installed in the completed building has been separately contracted for the tenant fit out stage of the project. During the core & shell portion of the project all bathrooms and elevator vestibules will be completed with recessed lamps while service rooms such as mechanical and electrical will include linear strip lights. All lighting fixtures will be LED, most of which run on 277V in this particular case.
The primary mechanical systems will be located on the first floor of the building this includes two water cooled chillers, five condensing boilers, as well as expansion tanks and air separators for both heating and chilled water. One air cooled chiller with a capacity of 215 tons will be located at ground level adjacent to the loading dock. At roof level a two cell cooling tower is to be installed which will perform at 600 tons per cell. The penthouse will hold two outdoor air handling units with an energy recovery heat exchanger while throughout the building there will also be a total of 12 indoor air handling units ranging from 12,000 to 20,000 CFM. Air will then be distributed by fan powered VAV units on each floor. A total building heating load of 7,500 MBH and cooling load of 950 tons were used for the design of the mechanical systems.
Mechanical
Structural
An existing structural system which consists of structural steel and concrete on metal deck will remain largely intact. A typical bay on the office floors (2-6) is comprised of W18x55 girders and W12x27 beams supporting a flor slab of 6 ¼” lightweight on composite steel deck. Each of the single story building additions will have 5” normal weight concrete floor slabs poured on grade as well as an 8” slab on grade in the loading dock area. These additions will be supported by a foundation consisting of spread footings which range from 6x6 to 12x12.
On the seventh floor of the building the structure will be strengthened to support the new outdoor terrace as well as an extended office floor which will cover an area which was formerly part of the roof system. These reinforcements will utilize W12x16.4 beams and W14x34 girders below a 6 ¼” slab. Additional structure will also be installed on the roof to support the skylight, elevator machine room, and office extension roof.
For this building the fire protection system is a wet pipe sprinkler system in nearly all locations. The only exception to this is that in the loading dock area of the building a dry sprinkler system will be used. Each of the three fire stairs will house standpipes which run from the first floor of the building up to the seventh floor. In the atrium area of the building all sprinkler heads are designed in accordance of section 404 in the International Building Code which regulates fire suppression systems for atriums.
Fire Protection
Transportation
All five of the existing elevators will be demolished and replaced with six total elevators in the same shaft location. Of these six new elevators five will be 6’x7’ and primarily used for passengers while one service elevator will be 6x8’8” with doors to allow access on either side. Two of the three existing stairwells in the building will remain in their original location while the third will be demolished as a portion of the atrium. This third fire stair will be relocated approximately 35 feet east of its former location. The fire stairwells are all designed with a 2-hour rating per the prevailing code. A fourth architectural stairwell will be constructed in the atrium and will not be fire rated.
One telecommunications closet will be located on each of the primary office floors (2-7). This closet will house all necessary communication and data lines for the offices to appropriately function.
