Northeast
Engineers & Consultants, Inc. was hired to
perform a geotechnical investigation for the proposed
development at Corpus Christi Parish. This proposed
development consists of a new church building,
adjacent to the existing parish center building.
The church will have a main floor area of 24,291
square feet and a partial basement of 4703 square
feet. The main floor will be set
at an elevation of 215.5 feet, and the partial
basement, beneath the east portion for the church
will have a floor elevation of 205.5 feet. The
front of the new church will be connected to the
parish center by a central courtyard, and a bell
tower will be located to the west of the courtyard.
New paved parking is planned around the church
site.
The Scope of Work for this project included the
following:
A field exploration program that consisted
of drilling, logging and sampling 14 borings;
5 borings were drilled to a depth of 30 feet,
while the remaining 9 borings were drilled to
a
10 foot depth.
Engineering analysis of the results of the
field explorations were used to develop site
preparation and foundation design recommendations
Preparation of a report summarizing the results
of the field exploration, engineering analysis
and recommendations for the project.
NE&C's investigations revealed loose sandy
soils at variable depths across the site. The
primary geotechnical concern with these conditions
is the potential settlement of the building from
consolidation of the existing loose sandy soils.
NE&C's recommendations included substantial
grading to achieve the design floor subgrades.
Most of the site for the church will require excavation
below existing grade by as much as 5 feet, while
up to 8 feet of fill will be required along the
north side of the building and a portion of the
southern wing.
