Description
Crooked Creek Water Reclamation Facility is located in Norcross (Atlanta, GA) and is one of three water reclamation facilities in Gwinnett County. The facility was upgraded and expanded several times since 1972 and the most recent upgrade started in 2017 and the construction is scheduled to be completed in 2021.
The last improvement (Phase 4) consists in upgrade the electrical and computer systems, biological reactor basins, solids handling and clarifiers. These enhancements will result in better environmental protection, odor control, and noise control. Thus far, the construction project reaches $30MM.
ULMA Solution
ULMA is taking part in two areas of construction: Reconstruction of the old filters and construction of a new filter area. The filters will have the capacity to carry around 16 million gallons of water per day.
To build both areas ULMA propose to use the heavy-duty and versatile modular panel formwork MEGAFORM, the lightweight handset panel MEGALITE and the 20k frame shoring system MEGAFRAME. Each system was used in different areas to provide the best-tailored solution. ULMA’s expert technical team was available during every phase of the project to make adjustments and changes in order to keep the project successful and on schedule.
One of the design challenges was to adjust the forming systems to numerous columns and wall sizes. Also, the solution that ULMA provides to the Alberici Construction was studied taking into account the job site challenges: limited space, underground utilities and keep the plant in operation.
This project required 30,000 SQF of MEGAFORM, the modular panelized system (in imperial measurements) that has the capacity to support high concrete pressure of up to 1,650 PSF. MEGAFORM was used to erect the 30 feet high core walls and columns. The system can also be assembled to create large gangs connecting panels with adjustable clamps and MK Walers. The gangs can be safely moved using the Mega Lifting Hook to save men-power and time.
Nearly 10,000 – 15,000 SQF of MEGALITE handset panels (in imperial measurements) was used to erect the columns and some filter walls. MEGALITE provides a wide range of panels and it was the best solution to adjust to the various wall dimensions. The MEGAFRAME shoring system was used to accommodate the 30 ft. height requirements.
