Site Investigation | Plate Load Test to Facilitate Building Confirmation Application Review for Single-Story Logistics Warehouse
Ground investigation
Facilitating the confirmation application for single-story logistics warehouses! Presenting evidence of shallow foundation bearing capacity through flat loading tests to smoothly clear structural conformity assessments and reviews.
In the new construction project of a single-story logistics warehouse, technical inquiries during the building confirmation application and structural conformity assessment (suitability judgment), as well as inquiries regarding soil bearing capacity, can lead to delays in design modifications and the issuance of confirmation certificates. There is an increasing number of cases where examination authorities strictly demand objective evidence of ground strength, relying on estimated values from general sounding surveys. Geotech's plate load testing solution directly loads the shallow ground at the actual construction site to accurately measure ultimate bearing capacity and deformation coefficients, providing scientific and reliable evidence of allowable bearing capacity. By reflecting the obtained accurate soil bearing capacity data in the structural calculation documents, it becomes possible to minimize inquiries from examination authorities and expedite the confirmation application process. Furthermore, it can also be utilized as a technical basis for changing the excessively estimated pile foundation plan to "direct foundations (slab foundations, strip foundations, etc.)," strongly assisting in cost optimization with complete safety assurance and rapid commencement of construction.

basic information
In accordance with the standards of the Japan Society of Materials Science and the Japan Geotechnical Society JGS 1521, we will conduct multi-stage loading and unloading using reaction force receiving machines (such as backhoes) according to the design load, along with a loading plate with a diameter of 30 cm. The load values will be measured using a high-precision compression load cell, and the displacement values will be measured with a digital displacement gauge (such as CDP-50) with an accuracy of 1/100 mm, with automatic recording by a data logger. Before the fieldwork, we will perform operational checks of various equipment and calibrate the horizontal level to collect reliable measurement data. The calculated ultimate bearing capacity, long-term allowable bearing capacity, and deformation coefficients will be organized, and a technical calculation report corresponding to the structural compatibility assessment will be prepared.

Applications/Examples of results
It is ideal for providing reliable evidence to smoothly pass the ground bearing capacity verification during structural design of newly built single-story logistics warehouses and factories, as well as for confirmation application reviews and structural conformity assessments (suitability judgments). It can be used for rational design changes from pile foundation specifications based on estimated data to "direct foundations (slab foundations and strip foundations)," presenting clear responses to technical inquiries from review agencies, and supporting early project commencement through shortened design periods. Additionally, it can be widely utilized as explanatory materials on structural safety and economic efficiency for general contractors and building owners.
