Park Seismic provides services in data processing and reporting in MASW surveys for various types of projects (wind-turbine, soil, void, bedrock, 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 zultichannel seismic surveys (refraction or reflection seismic surveys).

The overall procedure for the service usually consists of following steps:
2. Survey Plans and Cost Evaluation
If client chooses to proceed with the MASW survey after considering the feasibility evaluation provided by Park Seismic, survey plans and estimated cost (quotation) are provided to the client. Options usually provide variations in cost and overall integrity of the survey. A small-scale pilot survey is often recommended as an option before the full-blown survey takes place to make a preliminary evaluation of the suggested acquisition parameters or overall effectiveness of the MASW approach for the project.

4. Data Processing and Reporting
After all data sets are delivered to Park Seismic, detailed analysis takes place promptly and a draft report will be sent to the client via email. A data set of one field day usually takes 1-3 days until a draft report can be submitted, depending on the complexity of data and analysis options chosen. The final report is submitted within 1-2 weeks after this in the form of both electronic files on CD and printed documents. During this period, minor changes or adjustments are made if necessary for certain parts of the analysis or reporting format based on communication (via email or telephone) between client and Park Seismic. The final report usually includes data files of shear-wave velocity (Vs) values at different depths along the surveyed lines. The report can be either in a compact or a full format; see sample compact 1D MASW report, sample full 1D MASW report, sample compact 2D MASW report, and sample full 2D MASW report.
