12. 901 New York AvenueWashington, D.C. Foundation Redesign POUR SEQUENCING FOUNDATION REDESIGN LEED • Change from column footings to a mat foundation • Potential savings in the schedule • Mat foundation will be more expensive (extra materials & labor) • Economical comparison Greg Blatt Construction Management

13. 901 New York AvenueWashington, D.C. Original Design POUR SEQUENCING FOUNDATION REDESIGN LEED • 146 Column Footings • 39 are combined footings • Smallest Footing – 4’-6” x 4’-6” x 21” • Largest Footing – 17’-0” x 17’-6” x 64” • 15,000 psi soil bearing capacity • Scheduled for 35 days • Estimated Cost of $645,966 Greg Blatt Construction Management

14. 901 New York AvenueWashington, D.C. Mat Foundation Design POUR SEQUENCING FOUNDATION REDESIGN LEED • Check for punching shear • Determine thickness for different strengths of concrete • Estimate costs for each strength of concrete • Estimate time duration • Compare to column footing design Greg Blatt Construction Management

16. 901 New York AvenueWashington, D.C. Mat Foundation Design POUR SEQUENCING FOUNDATION REDESIGN LEED • 6,000 psi concrete foundation was the least expensive of the 4 options analyzed • Estimated to take 45 days to complete Greg Blatt Construction Management

17. 901 New York AvenueWashington, D.C. Foundation Comparison POUR SEQUENCING FOUNDATION REDESIGN LEED Greg Blatt Construction Management

18. 901 New York AvenueWashington, D.C. Foundation Conclusion POUR SEQUENCING FOUNDATION REDESIGN LEED • Mat foundation costs approximately $810,000 more than the column footings. • Mat foundation is estimated to take 10 more days to complete than the column footings. • Overall, the column footings were a better choice as a foundation system for this project.
