Bidding and Estimating Flashcards
Quantity Take-off Method
Counting the number of items associated with a particular construction project, determining the associated materials and labor costs, and formulating a bid.
Consider:
Subcontractors if needed
Project overhead
Company overhead
Labor burden
Project equipment
Contingencies
Allowances
Add markup for profit being careful to keep your bid competitive
What is Bid Shopping? (unethical practice)
Bid shopping is the practice of revealing a contractor’s or subcontractor’s bid to other prospective contractor(s) or subcontractor(s) before the award of a contract in order to “shop” around, inviting other competitors to beat it.
What is Bid Peddling? (unethical practice)
Bid peddling is bid shopping in reverse. Bid peddling occurs when a subcontractor who is not selected for a construction project tries to induce the prime contractor to substitute his or her company by offering to reduce their price
What is Bid Rigging? (unethical practice)
Coordination among bidders that undermines the bidding process and can be illegal. Bid rigging can take many forms, but one frequent form is when competitors agree in advance which firm will win the bid
Process of Estimating
Flowchart
What is included in the labor burden?
The extra administrative costs of employing laborers. The cost of employment taxes and insurance (Medicare, Social Security, unemployment insurance, workers’ compensation, liability insurance, etc.) must be considered. These obligations add approximately 30% to your labor costs
What are Allowances?
These are funds allocated to specific items in the budget. For example, the lighting allowance will establish that all light fixtures be purchased for a certain amount. If the owner changes his/her mind, and chooses more expensive fixtures, they must be purchased by the owner above and beyond the contract price.
What is a Project Overhead?
These are costs that are associated with the project but are not labor and materials. Examples of project overhead are utilities, temporary storage and office costs, security, dumpsters, and sanitation.
How to add Markup & determine profit
Markup in the construction industry is 15%. The cost of the project, plus overhead and markup is the most common way to arrive at a bid. Markup should be applied to direct costs (labor, materials, equipment, project overhead and subs).
What is a Conceptual estimates
Using information from previous projects to arrive at a rough cost for budget purposes without designing the entire project.
After this process is complete the owner will enter into the design stage.
What is a Square-Foot estimates?
Square-foot total - measuring the square-foot of the entire building and multiplying a square-foot unit cost number based on past project history.
Square-foot area - measuring the square-foot of the specific trade work and multiplying a unit cost number for their perspective work.
What is a Unit Price Estimate?
This is a form of construction estimating that bundles all the cost components like labor, materials, equipment and subcontractors to arrive at a unit price for the entire job.
What are Common Sources of Error in estimating?
- Errors in Calculations & Measurements.
- Incorrect Labor Rates.
- Improperly Priced Materials and Supplies.
- Using Incorrect Units of Measure.
- Failure to Visit the Project Site.
- Overlooking or Miscalculating Haulage Costs.
- Failure to Review Building Codes, Permits and Inspections.
- Failure to Consider Quality of Workmanship Required.
- Omitting Items Considered to be Minor.
- Failure to Review the Bids of Subcontractors.
- Taking Shortcuts in Cost Estimating.
- Not Allowing for Realistic Contingencies.
- Overlooking Items.
What is the importance of Job Cost Recording?
Information can be learned from keeping track of actual costs in comparison to estimated costs, and be later used in future estimating and bidding process. It is recommended to use Construction Specifications Institute (CSI) forms, specifically 2004/2010 CSI Masterformat Cost Codes.
__________ are used to monitor and evaluate a contractor’s costs during the course of a construction project.
Cost codes
Is profit considered a cost? And should it be factored into your cost codes?
No
