@Greg O'BrienAs a business owner I can expense an allowed amount each year of furnishings, office equipment, tools, machinery,equipment.Of course, I know the cost of the furnishings since I purchased them.

Wow, sounds like the operator, not the machinery.

Terri, LOL, several aspects here, all over the map sort of.Then you know that in a manufacturing environment different industries have different allocations and leverage operations differently, costs of capital improvements, machinery can be very expensive and payoff or retirement of debt can be long term measured in ten or hundreds of thousands of units produced, such as a car maker.

Make sure you have contract language on daily cleaning, key words to use are "daily basis", "broom cleaning or equivalent" and "removal from worksite"  Make it apply to (rubbish, waste materials, tools, construction equipment, machinery, and surplus materials), and include a statement of back charge of cost plus 10% if you have to perform the cleaning. 

You've also got to remember that if you're trying to salvage materials, a lot of the demo will have to be done by hand instead of with heavy machinery, which adds $$$.If you want you can take a shot and post on FB marketplace and CL.

Uphill is significantly more costly because the productivity factors of the excavating machinery is an order of magnitude different. 

Agricultural machinery and equipment not including cotton gins, grain bins, and fences is 5 year property now if purchased NEW. 

A concrete batching plant consists of a mixing chamber where raw materials are mixed with water and sand, producing ready-mix concrete for use onsite; it also has storage tanks for holding water required during mixing operations.If you are looking for a concrete batching plant division for designing stationary and mobile concrete batching plants in Ahmedabad, then contact Coninfra Machinery Pvt.

Depreciation is always based on purchase price.Think of it this way:  Business assets (whether a piece of machinery or a house) are purchased to generate income. 

In my opinion:Generic Office TI's = NoEntire Office Building/Single Tenant/Large Office Build-Out... 40,000 sf+ = yesRestaurant Build-Out = yesGeneral Industrial TI's = NoIndustrial TI's w/machinery monuments = yesApartment Value Add = No Cost Segregation Professionals (not CPA's) but actual Cost Seg/PM's will dig deep into your construction scope (not just $$$ after the money is spent).
