Prefabrication Saves Time and Money for Oakwood Village Prairie Ridge

Project Overview

The Oakwood Village Prairie Ridge Campus project included the construction of three towers built over structured parking for the addition of 73 new independent living apartments. The scope of work included an expansion to the existing assisted living entry care facility, construction of a three-story building for 30 additional one-bedroom apartments, common areas, and support spaces. Renovations were performed to the existing common areas including pub and bistro food service venues, community center corridors, the lifelong learning center, the gift store, the equipment and exercise floor, the chapel, the marketing suite, and a new space for the creation of a spa. The clinic, business center and library were also relocated to the basement.

Challenges

A state-wide building boom resulted in a labor shortage and limited manpower. Having started the operation two weeks behind goal, prefabrication was key to make up for lost time and get the schedule back on track. Crew members needed to be assigned to other portions of the building to keep the schedule moving.

Three towers needed to be assembled simultaneously which created a tight timeline from the start. Upfront coordination with the wood framing supplier was critical and communicating how JP Cullen planned to sequence the assembly of the towers. Sequencing was determined by move in date of the tenants. There was a two-week period between the start of each tower.

Solution

Prefabrication of the three towers included 2,404 wood joists, 355 headers, 2,616 wood frames, 3,267 floor trusses and 114 roof trusses. The prefabrication of these components got the schedule back on track to complete on time and made up for the two weeks that were lost.

Results

Prefabricating portions of this project resulted in 10% cost savings and 25% schedule savings.
