Bottom-of-Chain, or Low-Tier
What is Bottom-of-Chain or Low-Tier?
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.

What are General and Administrative Costs (G&A)?
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.
What is Work in Progress (WIP)?
In construction accounting, work in progress (WIP) refers to the value of construction projects that have started but are not yet completed at a specific point in time. It represents the costs incurred and revenue earned on ongoing projects. Key aspects of WIP include everything from cost tracking, revenue recognition, billing cycles, and financial reporting to schedule monitoring, change order management, retainage tracking, and tax planning.
As mentioned in our WIP Accounting Principles blog post, understanding WIP is a critical component of running a profitable business. This is because it offers several key benefits:
- Financial Health Tracking: WIP reports help to identify potential issues before they spiral to keep projects on track. For example, it can help spot gross margin slippage early on and alert project managers that they need to course correct.
- Cost Management: Comparing work completed to the budget spent will alert subcontractors if project expenses are running too high. For instance, if only 25% of the work is complete, but 40% of the project labor budget has been used, it indicates the need to reel in costs.
- Compliance: WIP reports help ensure that invoices align with work completed, reducing the risk of pay app rejections
- Profitability: WIP reports systematically account for project-related costs and revenue. This gives subcontractors a clear picture of which projects are most profitable and spot trends to help determine the best project types for the business.
Effective WIP management is crucial for subcontractors' financial health. Modern billing and cash flow forecasting software, like Siteline, enhances WIP accounting by centralizing data to increase financial visibility, improve informed decision-making, and optimize cash flow.

What is General Liability Insurance?
General Liability Insurance, particularly applicable to the construction industry, is a specific type of coverage that safeguards construction businesses against financial losses due to liability claims. These losses may arise from bodily injuries or property damages that occur on the construction site. It can also extend to cover slander, defamation or false advertising claims. Moreover, in the event of any such undesired incidents, the insurance policy is responsible for handling lawsuits and paying out the settlements. However, it's essential to note that general liability insurance doesn't cover damages due to professional errors or employee injuries; these would fall under professional liability insurance and workers' compensation, respectively.
