What is a Project Manager?

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.

Cost Plus Billing in the construction industry refers to a method where the customer agrees to cover the actual costs, expenses and other direct costs of the construction project plus an additional sum for contractor’s overhead and profit. These typically include costs of materials, labor, and subcontractor charges. The agreement clearly establishes and defines what is constituted as cost, the overhead percentage, and the profit percentage, reducing the risk of any surprise costs. Essentially, the 'Cost' represents the direct costs of the construction, while the 'Plus' is the contractor's fee and is usually agreed upon as a fixed percentage of the total costs or as a target price with a shared savings clause.

General and Administrative Costs (G&A) in the construction industry refer to expenses associated with day-to-day operations that are not directly tied to a specific project. These are necessary costs for a business to operate but are not easily assignable to a particular construction job. They typically include office rent, utilities, office supplies, insurance, legal fees, accounting services, salaries of non-project related staff, and other management expenses. It's important for construction businesses to carefully manage G&A costs as they can significantly impact the profitability if not monitored and controlled carefully. These costs are usually spread proportionately across various projects, based on some measure like total project labor costs. A high amount might indicate inefficiency, while a very low amount could suggest underinvestment.
