Scheduling or Budgeting and Accounting
  • Schedule payments and orders so that cash flows provide maximum benefits to the company. For example, order supplies near the end of the month to reduce billing periods and receive discounts for paying within fifteen days of receipt. (3)
  • Perform cost-benefit analyses for equipment and materials. For example, an electrical estimator tracks the initial and follow-up costs of two switches. The estimator determines the more expensive switch is more cost-effective when he factors in follow up labour and part replacement costs into the analysis. (3)
  • Establish and monitor schedules for long-term multi-phased projects. Establish critical timelines and schedule the activities of staff, consultants and contractors. In addition, coordinate tasks with other departments and companies, including multiple specialty trade contractors. Many factors such as sub-contractor, material and equipment availability, construction difficulties, and extended wet weather have a large impact on project schedules and require constant monitoring. As a result continually adjust schedules to ensure project timelines are met. (4)
  • Determine and monitor budgets for large and small concurrent projects. Consider labour, material, equipment, contractor and auxiliary equipment costs using established costing rates and profit mark-ups. Monitor expenses to ensure projects are within budget, and adjust schedules and budget lines to accommodate unexpected delays and costs. Project costs are often in the range of twenty thousand to on hundred thousand dollars but may run to millions of dollars for multi-phased projects. In addition, prepare financial summaries to monitor profits and losses. (4)

Measurement and Calculation
  • Take measurements using a tape measure during site visits to verify quantities of material. For example, measure lengths of wiring. (1)
  • Calculate quantities and volumes. For example, when preparing estimates for roadway construction calculate the quantity of gravel required using area and depth of coverage and the grade of slopes as factors. (2)
  • Calculate missing dimensions on scale drawings to accurately determine quantities. Construction estimators must take measurements from scale drawings and calculate areas, perimeters and volumes, and may have to create a new scale drawing to determine the missing dimensions. (3)
  • Calculate material quantities for jobs involving complex and irregular shapes. Set up equations to calculate height, depth, angles and degree of curves using principles of geometry and trigonometry. Insert these dimensions into formulae to determine the volume of material required to bring sections of roadways up to grade level. (4)

Data Analysis
  • Average labour and material costs to guide future estimates. (2)
  • Analyze monthly data on labour and material performance to identify problem areas and depict trends over time in quality, defects or efficiency. For example, monitor product failures and replacement costs to draw conclusions about the cost effectiveness of products. Analyze project costs such as labour costs versus budgeted costs and equipment downtimes to determine if there are areas to improve efficiencies. (3)
Back to Top

Numerical Estimation
  • Estimate the time needed to complete construction projects. Consider factors such as the complexity and size of the projects, the weather conditions expected during construction, equipment and materials needed and special requirement for particular types of jobs. (2)
  • Estimate profits. Consider factors such as potential variations in cost and charge rates, potential project delays and possible cost overruns. Most factors are known but fluctuations can occur within plus or minus two percent. (3)

Job Task Planning and Organizing
  • Construction estimators organize their tasks to complete research, estimate project bids and manage project contracts for their employer or client organizations. They usually work on multiple projects, which can vary in length from one day to two years depending on the size and scope. Job tasks and priorities are project driven, but they decide the priority of tasks. They plan their daily, weekly and long term schedules to fit in activities, which may include: meetings, site visits, quote estimations, presentations, project management and quality control and productivity analysis. Their daily activities can vary widely from day-to-day. They work in fast paced environments in which they must be able to determine which projects and issues take priority. They must always be willing to reorganize their work schedule to deal with problems and situations as they arise to ensure projects stay on schedule. They interact with supervisors, contractors, colleagues and clients often in a coordinative role to integrate their tasks with others. Construction estimators are often involved in operational and strategic planning by virtue of their job. Based on their understanding of an organization, they identify and complete estimates for a wide range of construction projects. They may plan and monitor project budgets and schedules depending on their level of experience. They coordinate the overall project work plan and provide operational and quality control recommendations and directives. They identify and establish staffing and contractor requirements. They may coordinate activities and tasks to complete projects. Senior estimators are responsible for assigning and monitoring the work of junior estimators. (4)

Decision Making
  • Make product-purchasing decisions. Decisions have a large impact on profit margins. For example, decide to purchase generic brands rather then name brands to increase profit margins. Decide to purchase products that are more expensive but have lower malfunction rates over time. (2)
  • Decide which contractors and suppliers to use. Adapt and use standard evaluation criteria and price points when awarding contracts and accepting supplier's terms. Legal implications make decisions difficult to reverse. (2)
  • Decide to bid on projects. In addition to set decision procedures consider the amount of work confirmed, project timeframes, costs, equipment and human resources availability, and the chances of winning the contract. Decisions usually cannot be reversed due to bidding deadlines and binding contracts. Deciding which estimate requests to respond to is an important business skill. (3)
  • Decide how to deal with contractors who fail to show up for jobs or do not complete work to specifications. In some cases, withhold payment until completion of work or reduce payments to offset work delay costs. Consider past relationships with the contractors and the cost implications to the project when making decisions. Binding contracts can limit how to deal with these situations, and decisions must be geared towards motivating the contractor to meet their contractual obligations with minimal impact on overall project timelines and costs. (3)

Problem Solving
  • Face clients who are upset because of inconveniences during construction such as the lack of an access road to sites. Take corrective action by building temporary driveways to enable the clients to reach the sites during construction. (1)
  • Deal with unexpected physical obstructions or problems during construction. For example, find that roadway construction designs will result in the uneven seaming of connecting roads. Speak with project managers and technical experts to determine alternative constructive methods that will remain within budget. Obtain approval from clients to continue. (2)
  • Deal with cost overruns or project delays due to weather, slower progress then expected, contractors not being available when required, and materials and equipment not arriving as scheduled. For example, discover that critical materials are on back order from the manufacturer. Identify alternative material and speak with clients to obtain approval. When possible speak to the clients to explain the unforeseen situation and to try to reach shared cost compromises. (2)
  • Experience faulty work completed by contractors. For example, you discover incomplete installations of safety straps around inground gas tanks. Identify the deficiencies and have the contractors redo the jobs. Adjust work schedules to accommodate resulting delays. (3)
  • You experience increases in service calls. Investigate the calls to determine causal factors such as equipment or components breakage, worker carelessness and faulty equipment. Make recommendations for corrective action such as replacing components, changing component brands and providing training to servicing staff. (3)
  • Face owners and general contractors exerting pressure to resume work before receiving engineering approval. Emphasize the legal and cost implications of proceeding prematurely. (3)

Finding Information
  • Locate pricing information for construction materials by searching internal and online supplier databases. (1)
  • Locate technical information from past projects, professional publications, co-workers, supervisors and colleagues to evaluate specific products, procedures and contractors before deciding what to buy, who to hire and what to quote. (2)
  • Identify and consult with content experts and co-workers to get their opinions on pricing and estimating details. (2)
  • Draw on information from drawings, reports, timesheets and repair and replacement reports to monitor and improve project efficiencies and productivity. (3)
  • Locate estimating information from bid specifications, codebooks, drawings, technical reports, costing and material databases and manuals. Use technical expertise to integrate the information to complete costing estimates. (3)
Back to Top

Critical Thinking
  • Regularly evaluate the quality of construction materials and equipment by studying specifications, speaking with colleagues about their experiences, reading user reviews on supplier websites, and monitoring malfunctions and breakages. (2)
  • Evaluate the feasibility of completing projects within clients' proposed budgets and timeframes. Consider timelines, season, equipment and human resources availability, complexity of project, including unknown factors. (2)
  • Evaluate the quality of quotes using standard procedures. For example, review costing procedures used and compare prices and work details with specifications to ensure accuracy and overall consistency. In addition, use knowledge and expertise to interpret and assess more subtle information not implicit in the bid and make suggestions or modifications that will enhance the quality of the bid and the chances of winning.
