Lanier High School, Addition and Renovation
MLA Geotechnical won the quality control inspection bid for this $4.4 million expansion with an original competitive estimate. As the project neared its completion and with MLA Geotechnical still under budget, the owner requested an additional services addendum to cover any miscellaneous costs associated with the end of the project.
MLA Geotechnical was proud to be involved in this project that added 14,000 sq. ft. of new educational space to Lanier High School in Austin, Texas. The project expanded the campus of Lanier High School with a new parking lot, science building, and agricultural barn. MLA Geotechnical served as the geotechnical engineer for this project. An addendum to this contract was required based upon a scope change requested by the client and revised final geotechnical recommendations were completed. The geotechnical investigation consisted of placing 4 borings across the site to provide foundation and pavement recommendations. Laboratory testing was limited due to near surface limestone and consisted of Atterberg limits and moisture content tests performed on representative soil samples. Geotechnical foundation and pavement recommendations were developed from the field and laboratory data including options for both spread footing and drilled pier foundations. Recommendations were included for reduction in potential soil movement due to shrinking and swelling clays, bearing stratum and bearing capacity for pier foundations, bearing stratum and bearing capacity for spread footing foundations and pavement thickness design.
MLA Geotechnical performed proctors, subgrade densities, base course densities, HMAC bulk sample testing, and concrete curb testing on the parking lot expansion. The 10,000 sq. ft. science building required proctors, subgrade density testing, building pad density testing, pre-pour reinforcement and concrete testing of the slab and mortar, and grout testing for exterior masonry. The 4,000 sq. ft. steel building agricultural barn required proctors, subgrade density testing, building pad density testing, pre-pour reinforcement and concrete testing of the slab, and welding inspections of the steel frame construction.
