Challenge: Peak was challenged with constructing a large-scale project with a tight schedule located on a site containing heavy rock, close residential neighbors and requiring the relocation of a 20” water main that ran through the center of the building pad. Additionally, the amount of concrete needed for the slab and tilt-wall necessitated an onsite batch plant calling for deliberate logistics planning.
Solution: Mitigating the heavy-rock site demanded extensive blasting and crushing over the course of the project. Processing the rock into 2A material required multiple crushers working 24/7 simultaneously, and some areas required up to 20ft cut and fills to balance the site. Subsequently, the project team was able to effectively reuse most of the 2A product as the sub-base for the parking lot areas. The project team also worked with the residential neighbors to alleviate their concerns regarding timing and noise of construction activities by adjusting subcontractor scheduling and going so far as to amend the sound of the back-up alarms on concrete trucks. An onsite batch plant was established to produce the significant amount of concrete needed for the slab and tilt-walls. The project team developed detailed logistical planning, which was paramount to maneuver equipment, while allowing access so all construction activity could proceed without interruption. It was this detailed planning that also incorporated sequencing and relocation of an existing 20” water line running through the center of the building pad. Peak worked with the site subcontractor and local water authority to schedule all relocation activities accordingly allowing the start of foundation pours, albeit creatively south to north vs. east to west, concurrently. Peak’s proactive planning produced a finished site one month ahead of schedule.
