House survey

This is a survey to compare and examine the condition of the house before the start of construction and after its completion.

A "building survey" is an investigation targeting areas within a site that are likely to be affected by construction work, conducted by a third party. There are preliminary and post-construction surveys that measure and record the current state, including changes over time, leakage conditions, defects in fixtures, and the tilt or subsidence of the building, along with photographic documentation. Through these preliminary and post-construction surveys, it is determined whether any damage existed prior to the construction or if it was caused by the construction work. [Preliminary Survey] - Photographs are taken to accurately understand the current state of the building and structures. - The interior of the building is investigated with the consent of the owner and users. - Measurements and records are made of the width and length of cracks, gaps, and damages, as well as the current tilt and subsidence of the building, along with photographic documentation. [Post-Construction Survey] - Photographs are taken of the current state in various areas. - The current conditions, leakage situations, and defects in fixtures are recorded, comparing them with the records from the preliminary survey to determine the presence or absence of impact, along with photographic documentation. *For more details, please refer to the PDF materials or feel free to contact us.*

Shape estimation survey "Borehole Sonar"

Shape estimation survey using φ86mm or φ116mm boring holes.

At Monitoring Service Co., Ltd., we conduct a "Borehole Sonar" that estimates the shape of the base of cast-in-place piles and precast piles by reading reflections from the boundary with the ground. It is fundamentally the same as an IT test, where a measuring device (sonde) is inserted into the boring hole provided in the pile, and an artificial impact is applied horizontally to generate elastic waves. It can also be applied to ground improvement columns. *For more details, please download the PDF or feel free to contact us.

Noise source investigation

We have prepared two devices to explore the source of sound! The "acoustic camera" visualizes sound using thermography!

Nanyang Wood Co., Ltd. conducts "Noise Source Surveys." We have two devices to explore the source of sound: a digital sound level meter and a visualization device using an acoustic camera, which will help identify the location of the sound. With the digital sound level meter, measurements can be taken from 30 dB to 130 dB. Measurements can be made in seconds, and the data can be graphed to show the fluctuations in noise levels. Additionally, measurements with the acoustic camera allow not only for the identification of the noise source but also for measurements of the surrounding space, enabling pinpoint confirmation of where sounds are coming from and the range of audible sounds. [Features] <Measurements with the Digital Sound Level Meter> ■ Measures noise levels in dB (decibels) ■ Capable of measuring from 30 dB to 130 dB ■ Measurements can be taken in seconds, and the data can be graphed to show fluctuations in noise levels *For more details, please refer to the related links or feel free to contact us.
