wareHOUSE(1) - 1900 greenwood PROJECT UPDATE 11.25.2015


Evanston, Illinois 60201

adas/spatz properties 

PROJECT UPDATE (11.25.2014):

We have been BUSY…have had a crowded job site. CONCRETE, CARPENTRY, ROOF INSULATION/MEMBRANE, PLUMBING and HVAC contractors are efficiently on the jobsite at the same time. There will be an enclosed, watertight workspace in place in the next day or so.

The CONCRETE contractor has completed the ADA compliant interior ramp as well as the concrete privacy wall that isolates dodge avenue from our transitional parking area.

The CARPENTERS continue making good progress completing their pre-roofing insulation/membrane and skylight prep responsibilities. Interior framing and exterior opening infill continues with window installation nearing completion.

The ROOF INSULATION/MEMBRANE contractor immediately followed (the CARPENTERS) installing 4.5” polyiso rigid insulation (r28) over the existing modified bitumen roofing system. This was followed by a 60 mil TPO “white roof” membrane. During the “bidding phase” of the project we cut several test holes. Our investigation revealed that the previous roofing system had been “torn off” last time, thus we felt that re-roofing over that system would be a positive. The existing 5” perlite rigid insulation (r16) was also a positive and the existing membrane would expedite progress on the building interior. Most of the mechanical trades are “through the roof” with the remainder once they are on the job full force. It’s easier/faster for the ROOF INSULATION/MEMBRANE contractor not to have lots of penetrations to work around and to flash them later, thus we get a better final result.

NEXT…CARPENTERS continue with interior mezzanine framing. PLUMBING begins with above ground waste, vent and water piping.  The ELECTRICAL contractor gets into the exisitng electrical service modifications and service panel feeds.

HAVE A GREAT HOLIDAY SEASON… enjoy the photos and video


CONCRETE: miguel is prepping for slab infill at abandoned loading dock.  
CONCRETE: starting to grade for ADA compliant ramp.
CONCRETE: ramp is complete, ready for exterior opening infill and interior framing.
CARPENTRY: existing exterior skylights have been removed, that material will be re-cycled. renovation is NOT cost/energy effective. kris and peter prep each existing opening for a new 4' x 8' insulating skylight and infill the balance for new insulation/roof membrane. each of these units will have (3) 4' x 8' skylights.   
CARPENTRY: skylight opening modifications continue. everything is tarped to keep water infiltration to a minimum. raised skylight curb to follow.
CARPENTRY: new skylight curb in progress by Przmek.
CARPENTRY: curb has been framed and skylight installed. stud space will be insulated and drywalled later.
CARPENTRY: we use the lift as an elevator to get the skylights to the roof, then they are moved, gasketed and installed.
CARPENTRY: bathroom and mechanical rooms are being "roofed". notice the the 10' breakthrough on the left. this allows for tenant expansion to additional units.
ROOF INSULATION/MEMBRANE: materials are hoisted to the roof.
ROOF INSULATION/MEMBRANE: Analino and Ricardo on the job. 4.5" of polyiso rigid insulation is fastened to the existing roof deck. we only install what can be covered with the 60 mil TPO membrane that day. a special "contact" adhesive is rolled on to the polyiso and back of the membrane. it takes 10-15 minutes for the adhesive to cure, then the membrane is "flopped over" and rolled into place. repeat.
ROOF INSULATION/MEMBRANE: membrane is being installed, hand rolling to follow.
ROOF INSULATION/MEMBRANE:  membrane is being installed.
ROOF INSULATION/MEMBRANE: notice the roller in the center of the photo. most of the bubbles between the membrane/insulation are removed during rolling with the balance disappearing on their own in a few days.
ROOF INSULATION/MEMBRANE: a new roll of 60 mil TPO + andy's shadow.
ROOF INSULATION/MEMBRANE: it was more cost effective and "safer" to insulate/membrane the masonry parapet wall on the left than to tuckpoint the masonry leaving a non-waterproofed section.
ROOF INSULATION/MEMBRANE: vertical TPO sheet counter-flashes the horizontal.Intersection is heat welded.
CONCRETE: due to it's height, the privacy wall was poured in two sections with the joint occurring below grade.
CONCRETE: first height of wall is nearly framed
CONCRETE: a section of brick was removed to achieve the necessary aesthetic facing Dodge avenue.

CONCRETE: second section of wall is ready to be poured. the small piece of 45 degree angled wood (camfer) nailed into the form creates an edge that's less susceptible to breaking.
CONCRETE: forms stripped, concrete is curing. it takes about a month to attain it's maximum strength.
CARPENTRY: entry vestibules in progress, so are the unit demising walls. this section of the project has no second floor lofts...the existing ceiling height was too low.
CARPENTRY: Tomek is working on the entry vestibule to units 6 & 7.
CARPENTRY: units 4 & 5 interior framing are in process. this section of the project has enough volume for second level lofts.
CARPENTRY: Kris and Matt are laying out the service corridor exterior entries. there is one 8' overhead door and a 3'-0" man door.
CARPENTRY: Kris and Peter are framing the service corridor exterior openings.
CARPENTRY: service corridor is taking shape.
CARPENTRY: Przmek and Kris are installing windows in unit 2.
CARPENTRY: the 22' adjustable ladders are great, we have 2.
CARPENTRY: installing the 3/4" plywood deck at the mechanical room in unit 8.
CARPENTRY: framing the mechanical room in unit 7.
CARPENTRY: topping off the exterior entry off Dodge avenue at units 6 & 7.
CARPENTRY: Tomek is working on the "breakthrough" between units 8 & 9. each unit has one or two ways of linking to the adjacent unit. this allows us to accommodate a growing tenant.
CARPENTRY: more mechanical room and bathroom "tops".
