Westfield Century City Mall


Client: Schuff Steel Company
Location: Los Angeles, California
Project Duration: 2015-2016
Key Services: 3D BIM Modelling

Projects Details

Westfield Century City is a three level retail development alongside Santa Monica Boulevard and Avenue of the Stars in Los Angeles. Opened in 2017, Century City is the tail destination for the west side of Los Angeles, servicing a population of 14.5 million residents within the extended four-county trade area. Century City is located near Beverly Hills, one of the highest income neighbourhoods on LA’s west side.

Schuff Steel completed the fabrication and installation with PDC project managing and detailing over 9,200 tonnes of structural steel. This was a true global project with PDC teams operating in 3 countries working in multiple time zones, offering Schuff steel around the clock project support and live access to the structural steel BIM model.

PDC’s scope of work included the 3D BIM modelling and shop detailing of the structural steel on the following areas:

  • Structural steel columns, beams, trusses, boxed columns and horizontal braces to seismic codes;
  • Modelling and connection provisions for Core brace seismic vertical bracing systems 
  • Structural steel posts, hangers, kickers;
  • Temporary bracing and erection aids
  • Anchor bolts and embeds for the main steel connecting to concrete walls;
  • Retrofit steelwork to strengthen the existing construction platform and underground carpark;
  • Floor openings;
  • Modelling of curved bent plate for concrete pour stops with rebar’s and bent plates around the elevator slab openings;
  • Safety cable holes at perimeter and grid beams;

Projects Challenges/Highlights

  • Due to the retrofit nature of the project and constant design updates for retailer preferences the project design was subject to substantial variations throughout the duration of detailing, through superior model management PDC were able to track and perform changes with little to no detailing errors.  The end result was a steel structure with over 12,000 assemblies connecting together as planned and to the erection schedule.
  • PDC were able to execute the project though the use of advanced model tracing systems, our job management systems and the use of best practice PMBOK project management techniques to control costs, time and quality. 
  • Survey data was required for all column baseplates as the new structure sat on an existing platform of concrete waffle slabs and piers dating back to the 1960’s.  As the site was subject to years of seismic activity and non-documented upgrades, this meant that the original 1960’s as built drawings were of no use.  Over 1500 pieces of reinforcing embeds and steel beams were required to strengthen the existing concrete structure supporting the new steelwork above, countless survey data correspondence was received for each and every piece of this steel with full tractability needed for any questions from the field.
