OAC Update, October 19, 2016

Actionable Items

Stair Seismic Detailing
Status:
[10/12/16] There is on-going coordination regarding the connection points, hand rails and structural implications of the “Grand Stair” (the exterior stair that leads up the west side of the building).
[10/19/16] The structural engineer provided details to the construction team during the OAC meeting illustrating  the required concrete embedding of stair handrails and the location of the metal panels.

HVAC Unit Placement
Status:
[10/12/16] Rooftop units are schedule to begin placement (pick date) on 11/15/16.  This date may need to be adjusted as the developer is planning on opening a portion of the new parking garage and access cannot be blocked unless previously approved in advance.
[10/19/16] The General Contractor and the Developer have agreed on 11/22/16 as being the first day that the rooftop HVAC units can begin placement on the roof.

AT&T Conduits
Status:
[10/19/16] A couple of  issues with the previously installed conduits for the incoming AT&T circuits have been brought up:  Pull boxes were not provided in the conduit run at maximum 100′ intervals and no conduit has been provided between the building floors.  The incoming conduit terminates at the floor of the garage level and conduit sleeves are provided through the first floor slab but no conduit has been provided between the two to protect the incoming cables.

Domestic Water Service
Status:
[10/19/16] The Developer is working on providing a schedule to the General Contractor to establish when the permanent domestic water service will be connected and operable for the store.  In the meantime the Developer is reviewing how and how much temporary water service can be provided to the store.

Tower Crane Deck Openings
Status:
[10/19/16] Now that the tower crane has been removed the openings on the floor decks need to be filled in.  Schedule forthcoming.

OAC Update, September 21, 2016

Actionable Items

Additional cores are required in structural podium slab/deck post concrete pour.
Status:
[08/10/16] The Structural Engineer has approve some of the proposed locations. Four locations proposed were rejected due to structural impacts.
[08/17/16] The General Contractor has submitted alternate core locations to the Architect and Structural Engineer.  These alternate locations will be x-rayed to determine if they are viable locations.
[08/24/16 – 09/14/16] Evaluation of alternate locations is on-going.  One proposed location has been identified as being in conflict with a developer-provided lighting fixture and the Developer has agreed to relocate this fixture.
[09/21/16]  Locations of proposed cores have been reviewed and approved by the design and construction team.

Main Entrance Door Drainage
Status:
[08/10/16]The Developer has noted that moving the drains further away from the store will affect ADA entrance slopes.  A trench drain system is being researched to determine the best solution and it will be presented to the store for review and approval.
[08/17/16] A trench drain product has been identified and has been presented to the General Contractor for review with the design team.
[08/24/16 – 09/14/16]  A slot/grate drain option has been selected and is now being reviewed by Store representatives.
[09/21/16] The proposed drain solution has been reviewed and approved by the design and construction team.

Construction Proximity
Status:
[08/24/16 – 09/14/16] A issue with the current construction of the store and its proximity to construction going on at the adjacent mall structure has been identified. Information forthcoming.
[09/21/16] Issues with construction proximity have been evaluated and have been determined to not hinder the work of either the Developer’s or the store’s construction teams.

Masonry Enclosure for AT&T Conduits
Status:
[08/24/16] An absence of rebar has been noted in the masonry enclosure which contains the incoming AT&T conduits.  The General Contractor is confirming this with the Developer’s Contractors to determine that this is correct.
[09/14/16]  Rebar has been verified as being required and is scheduled to be installed by 09/20/16.
[09/21/16] While no additional details have been provided, the General Contractor has indicated that scanning of the concrete deck will be performed on 09/22/16. This is being done presumably to determine if adequate reinforcing has been installed/properly installed.

Elevator Openings
Status:
[09/14/16]  A 6″ masonry bump-out at the store’s elevator #2 has been identified and needs to be removed to facilitate proper installation of the elevator equipment.
[09/21/16] The identified concrete bump-out has been removed (completed 09/20/16) and final concrete repairs are scheduled to be complete 09/23/16.

Permanent Power
Status:
[09/21/16] The utility company’s (SDGE) third-party installation crew was scheduled to have the permanent equipment installed and powered-up on 09/20/16 but did not show up on site as scheduled.  The General Contractor is attempting to obtain a new schedule so that removal of the temporary generator set can be additionally be scheduled.

Tower Crane
Status:
[09/21/16] As the construction process is on track and the enclosure of the store structure needs to be completed soon the General Contractor is confirming with all of the sub-contractors to ensure that the proposed dismantle date of the tower crane of 10/09/16 is still viable.  As the crane is located within the footprint of the store construction it needs to be removed to facilitate roof construction and enclosure of the structure.
