3. With the advent of increased urbanization of our downtowns, retail grocers and developers have
responded to the opportunity with “the urban grocery store.” This session will review the challenges
and opportunities of downtown store environments, including entitlements, planning, engineering,
construction, parking and operational needs. Downtown markets are expanding in number, and are
increasingly more complex – and more expensive. We will feature mixed use tenancy of residential,
retail, commercial and parking. The project design and approval process is complex and protracted,
requiring an adept team to deploy and construct these projects. Join us for an insightful discussion
on urban grocery and get a realistic understanding of the necessary resources to successfully
deploy this type of store.
The Urban Grocery Store Tuesday, September 29, 2015
4. Develop a realistic understanding of resources necessary to
successfully deploy this project type.
Discuss the project complexities and regulatory hurdles to overcome.
Consider project scheduling and entitlement process.
Project benefits & incentives.
Understand the construction cost drivers

17. Scale and Massing: Corner Outparcel Building
PLACEMAKING: Small buildings can be HUGE in helping define the urban street edge and screen parking.
• Amenities (benches, transit waiting areas, etc.) are comfortable and conveniently located.
18. Parking Considerations:
This is America – People Drive Cars!
DRAFT IMAGES
In Urban context, emphasis is on pedestrians, not cars
21. Planning Considerations
Average Ground Floor Area’s 18K – 30K
Footprints are without exception non-prototypical & may not be rectangular
Limited ground sales floor require additional sales area on separate floor or mezzanine
Many locations feature mezzanines (sales + seating + support) or below grade support area’s
Floor to ceiling heights are critical allowing for sufficient clearances / coordination of S/MEP
Occupied floors above grocery – many cases these are residential that are “plumbing intensive”.
Cost to build in a downtown environment are much higher – Labor / materials transit…
33. Role of the Construction Manager
Understands the unique complexities of food store
construction
Prepares detailed project development schedules

against budget
35. Cumbersome and multi-faceted
permitting/approval processes
Long lead time items

44. MEPR Overview
• HVAC - hood exhaust/make up,
ventilation, dehumidification
• Plumbing – sanitary, grease
(interceptor), venting, water pressure,
natural gas, case condensate
• Electrical – voltage, service
size/location, generator
• Refrigeration – system type, location
• Other Issues – Many …
Bottom Line = Heavy coordination required
Urban Shell Before & After Fit-up
45. HVAC Systems
Hood Exhaust / Makeup Air
• Pollution Control Unit
• Space Requirements
• Exterior Louver
• Maintenance
• Exhaust to Roof
• Shaft size and location
• NFPA Clearance

46. HVAC Systems
Dehumidification
• Rooftop Units – hot
gas bypass, dual path
air flow system,
desiccant system
• Split Systems –
controls, reheat:
electric coil, hot
water coil, natural
gas
• Chilled Water –
controls, reheat:
electric coil, hot
water coil
• Water Source Heat
Pump, integral
AHU with DX coil and natural
gas duct furnace Water source heat pump with
integral dehumidification
47. Plumbing Systems
• Sanitary invert
• Grease invert
• Water -
size/location/pressure
• Natural gas – location,
pressure
• Venting – local
requirements
• Other – trap primers,
trap guards, AAV,
separate case drainage
system, drain pans for
sanitary pipes of
tenants above
Local code requires each
fixture to be separately
vented. AAV’s not allowed.
Each fixture to have Bow
Vent
Exposed sanitary piping from
tenants above, require drain
pans
48. Electrical Systems
• Service size/voltage – 208 volt or
480 volt. 480 volt service requires
a transformer.
• Electric room space –
approximately 200 ft2 in store or
mezzanine with department
electric panels
• Distance to service entrance
effects wire, conduit size, and
number of runs
• Generator – location (roof or
mezzanine), serves Emergency
Systems, issues: size, noise,
consider generator connection in
lieu of generator.
• Local code – more stringent
restrictions than NEC

49. Refrigeration – Machine Room Space, Roof Space
• DX System – Base system: Circuit Piping, Loop Piping,
machine room space, air cooled condenser roof space,
least cost
• Distributed DX System – multiple smaller
compressor/condenser units requires more space than
base system and additional costs
• Secondary System – Glycol; addition of circulating pump
and heat exchanger (maybe more than one) requires
more space than base system and additional cost
• Secondary CO2 System – multiple systems; LT, MT
requires more space and additional cost
• Cascade CO2 DX system – multiple systems, requires
more space and additional cost
• Ammonia Primary System – Expensive, safety concerns

Other Issues
• Local code requirements
• Real Estate – as in space available
• Type of urban setting, (typology) clearance to other buildings
• Construction issues
• Foundation – grade beam, garage, basement
• Clear height of space, mezzanine
• Construction coordination between landlord contractor and tenant contractor
• Scope of Work – Landlord vs. Tenant Improvement
• What is landlord responsible for, what is tenant responsible for
• Method of document delivery – shell/TI, below grade/above grade
responsibility
