The in-situ density of material is determined by the weight of the excavated material divided by the in-situ volume. The volume of the excavated hole can be determined from the weight of sand with known density filling in the hole.

One of the most commonly used electronic signatures today is the Text Typed signature; meaning that one has used a keyboard to type their name, with the intent to sign “something”. Although Text Typed is the most common, electronic signatures are not limited to this method.

Most other regulations and federal laws offer similar guidelines for digital signatures and electronic records. This means that a typed signature — especially when presented in the correct context — can serve as a legally binding substitute for a handwritten signature.

In 2000, the U.S. federal government passed the Electronic Signatures in Global and National Commerce Act (ESIGN), which in tandem with the Uniform Electronic Transactions Act (UETA) confirms that electronic signatures constitute legally binding documents if all parties choose to sign digitally.

One of the symbols to indicate an electronic signature is /s/, placed before the signer's name. For example, /s/ Jimmy Doe. The other symbol is the signer's name between two forward slashes, typed out, for example, as /Jimmy Doe/.

How do I sign my name electronically? You can sign your name electronically via any e-signing platform. All you need to do is upload or create your digital signature, save it as an image, and use it to sign online documents from your computer or phone.
