What is a percolation test?

In simple terms, a percolation test or "perc" test is a measure of a soil's ability to absorb water. A series of test holes from 18 inches to 36 inches in depth are dug with a post hole digger and the holes are filled with water for most of the first day to simulate saturated conditions. On the second day the actual test is conducted for a period of four to six hours. The test holes are filled with a prescribed amount of water and each hour the level of water drop is measured. The calculated result shows the absorption capability of the tested area and is used to properly size the septic system.

Q: The Building Inspector issued a "STOP WORK ORDER" for my project. Can a Structural Engineer approve the work that was done?

A: A structural engineer will need to make a site visit to your location to assess the situation. The engineer will also need to know why the building inspector did not approve the work as it was completed. The structural engineer will provide an independent opinion and in may cases will either recommend changes to your project to follow code requirements or write an engineer's letter stating that the work is acceptable as witnessed.

What's the difference between a Civil Engineer and a Structural Engineer?

Answer:
Civil Engineers design and supervise construction of homes, commercial and industrial structures, roadways, airports and other infrastructure. A Structural Engineer is first and foremost a Civil Engineer and may perform both functions in designs, inspections and certifications.

What constitutes a comprehensive site development plan?
A site development plan provides a detailed visual representation of a site's layout and configuration, encompassing building footprints, parking and street layouts, conceptual landscaping and lighting designs, site cross-sectional drawings, and building elevations. Prior to the issuance of building permits, a site development plan must undergo approval.

What distinguishes a site plan from a floor plan?
While a floor plan presents a scaled diagram of a single building story, highlighting the arrangement of rooms, a site plan offers a broader perspective, capturing all elements within the property lines, including topography in relation to building structures and pathways.
