Impact of Spring Snowmelt on Erosion and Sediment Controls

Early spring offers unique challenges for maintaining the integrity of erosion and sediment controls on construction sites. During the winter, vegetation is dormant, the ground is frozen, and substantial snowpack is formed. When warmer temperatures and spring rain arrive, these conditions can have negative impacts on erosion and sediment controls if SWPPP measures are not properly implemented.

Mold in Basements

Basements can be highly susceptible to mold growth if not suitably constructed, finished, and maintained. Basements are predominantly subterranean with exterior walls in direct contact with water.

Practices for Field and Laboratory Evaluation of Thermal Resistivity

In the design of heat generating underground utilities, such as electrical conduits, understanding the ability of the surrounding media to dissipate heat is a key parameter for design. Thermal resistivity, referred to as Rho (ρ) value and expressed in units of C.Cm/W or C.m/W, is the measure of resistance to heat flow through a material such as soil, concrete, or Fluidized Thermal Backfill (FTB) used as backfill or encasement for underground utilities.

Options for Controlled Demolition with Asbestos In-Place

In New York State, the demolition of buildings/structures with asbestos-containing materials (ACM) present must be performed in accordance with New York State Department of Labor (NYSDOL) Industrial Code Rule 56 (Part 56 of Title 12 of the Official Compilation of Codes, Rules, and Regulations of the State of New York, cited as 12 NYCRR 56).
