What is an Automated Clearing House (ACH)?

A Time and Materials Contract, often abbreviated as T&M, is a specific type of contract commonly used in the construction industry. It is a contractual format that indicates that the client will pay based on actual costs: the direct labor hours worked (time), the materials directly used in the final product, and a fixed add-on to cover overhead and profits. Unlike fixed-cost contracts, T&M agreements provide greater flexibility as the scope of work can change without having to negotiate a new contract. This type of contract is generally applied in projects where the full extent of the work cannot be determined at the outset. However, their major downside is the potential risk of cost overruns, which makes client oversight crucial.

Bottom-of-Chain or Low-Tier in the construction industry refers to the lowest level of subcontractors or suppliers involved in a construction project. They are at the end of the construction chain, typically providing specific services or materials as subcontracted by higher-tier companies. These can include specialized tasks like electrical work, plumbing, landscaping, or supply of construction materials. Their work is crucial as they lay the foundation for more complex tasks to be executed by upper-tier contractors. They are also bound by the contracts in place, like other members of the chain, although directly managed by mid-tier subcontractors instead of the main contractor.

Overhead, in the context of the construction industry, refers to the general, ongoing expenses associated with managing a construction company or project that cannot be directly linked to individual construction jobs or projects. These expenses can include administrative costs such as office rentals, utility costs, support staff salaries, and costs associated with legal compliance, insurance, and marketing. Overhead also includes costs associated with maintaining and repairing equipment, employee training, travel expenses, and team benefits. These costs are necessary for the business operation but do not contribute directly to a specific project’s profit. A proper understanding and efficient management of overhead costs are essential to maintaining business profitability and competitiveness.
