Park Seismic LLC specializes in the services of the MASW method that provides subsurface shear-wave velocity (Vs) profiles (1-D, 2-D, and 3-D) for geotechnical engineering depths (e.g., about 50-m depth).
Park Seismic provides services in data processing and reporting in MASW surveys for various types of projects (wind- turbine, soil and bedrock, void, weak zones, buried boundaries, etc.). For cost-effective and time-efficient purposes, field surveys are usually performed by a local geophysical company with experience in multichannel seismic surveys (refraction or reflection) according to the field procedure, details of which we will provide. We will then process acquired data and send you back the final report in a compact form (click for sample 1-D and 2-D report) or a full format (click for sample 1-D or 2-D report). The overall procedure consists of following steps:
Feasibility Inquiry - Free consultation on the scope of the approach
Survey Plans and Cost Evaluation - Providing field logistics for data collection and estimated cost for the service
Field Survey - Data collection by the local company
Data Processing and Reporting - Processing data and preparation of report and output data (final deliverables)
For most common size of the project that takes a few days of field work, the final deliverables are usually available within a week after receipt of the collected data. Contact us for free consultation.
MASW Services - Areas of Application
ParkSeismic LLC provides services in seismic investigation of geotechnical engineering projects including seismic site characterization (SSC) for Vs30m evaluation,wind-turbine site characterization, bedrock topography mapping, sink-hole hazard evaluation, detection of buried subsurface features of various types, soil characterization, etc., by using a special seismic technique called the MASW method. The multichannel analysis of surface waves (MASW) method is a relatively new ground-scanning method utilizing one type of elastic waves (surface wave) long studied and utilized in the earthquake seismology. The main advantage of this method is highly reliable survey results usually presented in 1-D, 2-D or 3-D formats even under significantly unfavorable conditions such as ambient noise.
In most cases, field survey can be accomplished within one or two days for a moderate size survey site (e.g., 100m x 100m) and draft results can be obtained by the next day, helping the geotechnical field process move quickly.
