Paper For Above instruction

The task involves estimating the bare cost for constructing steel door frames, including materials, labor, and equipment, utilizing the CostWorks estimation tool. The scope encompasses erecting frames for twenty steel doors, each measuring 6 feet by 8 feet, in Phoenix, Arizona. The framing will utilize 8-inch steel channels with a weight of 11.5 lb per linear foot (LF), complemented with anchors and bar stops. This detailed cost estimate is necessary for project planning and budgeting, emphasizing the importance of accurate material and labor cost assessments.

Introduction

Accurate cost estimation of structural framing components is essential in construction management to ensure project budgets align with actual expenses. The estimation of steel door frames using CostWorks enables project managers and estimators to analyze the materials, labor, and equipment costs accurately by leveraging detailed data inputs and standard cost bases. This paper discusses the process of estimating the bare costs for erecting steel door frames with specified materials in Phoenix, Arizona, providing a comprehensive breakdown of the key components involved in the cost simulation.

Material Cost Estimation

The primary material for framing is 8-inch steel channels, selected for their strength and compatibility with steel doors. Each channel weighs 11.5 lb/LF, and the total length needed for each door’s frame must be calculated. Considering a typical door frame, which generally includes two verticals and one header, the lengths can be derived based on the door dimensions. With each door measuring 6 feet (72 inches) wide and 8 feet (96 inches) high, the frame comprises two vertical channels of approximately 8 feet each and a horizontal channel at the top, also 6 feet in length, with additional allowances for material overlaps and anchorage.

Calculating the total linear footage, for twenty doors, the total vertical channel length is 2 x 20 x 8 ft = 320 ft, and the horizontal (top) channels are 20 x 6 ft = 120 ft. Including allowances for bar stops and anchors, an approximation of an additional 10% length is added. The total estimated required channel length is thus approximately 480 ft (vertical + horizontal) + 10% = 528 ft.

Using the cost per foot for the steel channels derived from CostWorks, which includes the current market price for 8-inch, 11.5 lb/ft steel channels in Phoenix, AZ, the material cost can be calculated. Assuming a cost of $8 per linear foot for the channel, the total material cost for channels alone is 528 ft x $8/ft = $4,224.

Labor Cost Estimation

Labor costs encompass the erection, assembly, and fastening of the steel frames. In Phoenix’s construction context, labor rates for structural steel work average around $40 per hour, considering local wages, overhead, and profit margins. The time required to erect each door frame depends on several factors, including frame complexity, worker skill, and accessibility.

Estimating about 2 hours per frame for individual installation, including positioning, bolting, and adjustments, the total labor hours for 20 doors amount to 40 hours. Consequently, labor costs are 40 hours x $40/hour = $1,600.

Equipment and Ancillary Costs

Equipment costs involve the usage of tools such as cranes, lifts, welding equipment, and hand tools. For small to medium-scale installations like this, equipment costs are often incorporated into hourly rates, with a typical equipment overhead addition of approximately 20% of labor costs. Therefore, equipment costs are estimated at 20% of $1,600, equaling $320.

Additional costs include anchors and bar stops, which are essential for securing the steel frames. Assuming these components cost approximately $50 per door, total costs are 20 x $50 = $1,000.

CostSummary

Summarizing the above calculations, the components are as follows:

• Materials (steel channels): $4,224
• Labor: $1,600
• Equipment: $320
• Anchors and bar stops: $1,000

The total bare cost for erecting the steel door frames in Phoenix, AZ, approximates to $7,144. This estimate provides an essential baseline for project budgeting, enabling stakeholders to plan resource allocation effectively.

Conclusion

Estimating the bare costs for steel door frame erection is a crucial step in construction project planning. By considering material costs based on precise weight and length calculations, labor expenses aligned with local wages, and equipment overheads, the overall project budget can be accurately forecasted. Using CostWorks, estimators can input detailed data to produce reliable cost assessments, aiding in effective project management and financial control in the local context of Phoenix, AZ.
