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.

A portion of the initial concrete slab pour is incomplete.
[Work Complete]

Status:
[08/10/16] The remainder of the pour is schedule to be completed on the day of the OAC meeting (August 10).
[08/17/16] Pour Complete.

Incoming AT&T Telecommunications Feed
Status:
[08/10/16] All conduit and pull box work was completed on Saturday, August 6.
[08/17/16] All AT&T cabling installation are scheduled to be completed by the end of the day on 08/19.

Stair Masonry
Status:
[08/10/16] This is a Developer-provided stair.  Scaffolding is schedule to be placed in a location which will not impact the construction of the store.  The Developer will provide a schedule for both the start and completion of the stair work.
[08/17/16] Work is ongoing. Schedule pending.

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.

Compactor Wall
Status:
[08/17/16] The footing wall at the compactor has been identified as being too high.  The exact elevation is being verified by the General Contractor and repairs will be made prior to work continuing in this area.

Finished Floor Survey
Status:
[08/17/16] The General Contractor is having the finished floor slab elevations surveyed to ensure that stair installations will proceed as planned.  Survey scheduled to be completed on 08/19/16.

OAC Update, May 12, 2016

The developer and the store owner have agreed to set a new floor slab elevation (datum) to accommodate the previously discovered 5/8″ discrepancy.  It has not been decided whether the 5/8″ will simply be absorbed into the final finished floor elevations (setting them all 5/8″ lower) or whether the floor will be floated with an additional 5/8″ of lightweight concrete to bring the final elevation up to the plans.

Due to site logistics and scheduling, the local utility company will not be providing temporary power to this portion of  the construction site.  A generator will be provided and connected to a distribution system to supply power to these areas of work.  The store construction site, specifically, will be provided with 1000 amps of 120/208V, three phase power and is scheduled to be completely installed and operational between June 6 and June 10.

The tower crane plans were approved and the area where the crane will be places has been leveled in preparation for its assembly.  The crane is scheduled to be assembled on the evening of Saturday, June 11.  Re-routing of traffic and transit will be scheduled with the City of San Diego and the local transit authority.  A flag man will be hired by the general contractor to keep vehicles from parking in front of or otherwise blocking existing fire hydrants along the street.

Shell Construction Document Timeline

For every project that gets built there are many schedules that need to be met.

Before an Architect or Engineer even thinks about starting to work on drawings the owner must analyze the needs of a project and determine a location for it. For the first year to as much as 10 years (this does happen, particularly with projects in remote locations) the project owner will negotiate with the owner or developer of a property to ensure that it will meet their needs from logistical and financial standpoints.

Once a commitment to the property is made the owner informs the design team of their intentions at this location and the first schedule can be created.

In the case of most retail projects this first schedule is known as the Shell or Base Building Schedule.  This sets up a timeline for the design of the exterior walls, roof, floor slabs and core infrastructure such as stairs and elevators.

A common Shell Building Schedule will look something like this:


Week 1

  • Develop preliminary site plan with utility connection points. Coordinate with Owner/Developer’s Civil Engineering drawings.
  • Develop preliminary floor plans.

Week 2

  • Project Kick-Off Meeting ….  Stay tuned ….
