Dean Rudy Hasl, Thomas Jefferson School of Law
Introduction
Thomas Jefferson School of Law, located in downtown San Diego, California, is an eight-story classroom building, with ground level retail space, and three levels of underground parking. Construction is structural concrete below grade, with a podium slab at the first floor, and eight levels of concrete slab above ground.
Structure:
University Classroom Building
Applications:
shotcrete foundation walls, structural slab and elevator pits
Architect:
Carrier Johnson
Engineer:
Hope Engineering
General Contractor:
Bovis Lend Lease
Owner - Developer:
Thomas Jefferson School of Law
Ready Mix Provider:
Vulcan Materials Co.
Product Type:
Hycrete360
Challenge
Pursuing LEED Gold Certification for New Construction building, the owner desired to contain costs while still achieving a structure with superior environmental performance.
Solution
By selecting Hycrete’s membrane-free approach to waterproof concrete construction, the school reduced the construction critical path by four weeks and saved an estimated $187,000 on construction costs, a 32% improvement over traditional waterproofing approaches. In addition, the US Green Building Council has awarded TJSL a credit for “Membrane Free Construction Through Integral Concrete Waterproofing” (Innovation in Design (ID) Credit 1.1) for its use of Hycrete360, which includes Cradle to Cradle Certified admixture Hycrete Endure WP.
Result
The project team was able to shave weeks off the construction schedule, saving them time and money. Hycrete360 provided a non-absorbent concrete surface with reduced maintenance over the duration of the building life span, all with a 10-year performance-based warranty. Environmental Impact: 1. Elimination of 36 tons of landfill debris. 2. Elimination of an estimated 53,844 pounds of non-renewable materials. 3. Elimination of an estimated 18,567 pounds of polymers. 4. Reduction in required onsite equipment – concrete waterproofing is added at ready-mix, not site. 5. Elimination of excavation / backfill required for membrane installation reduces construction footprint. 6. Improved concrete recyclability, as future membrane removal is eliminated.
