Steel Door Bare Costusing Costworks Estimate The Bare Costmaterials

Steel Door Bare Cost Using CostWorks, estimate the bare cost—materials, labor, and equipment—for erecting the frames for 20 steel doors using 8-inch channels at 11.5 lb./LF. Each door measures 6' x 8' and weighs 275 lb. Assume steel channels with anchors and bar stops for the framing. The job will be in Phoenix, AZ. Submit the CostWorks format, including all the data and calculations used to estimate the bare cost of steel doors.

Paper For Above instruction

The estimation of the bare cost for erecting steel door frames involves a comprehensive analysis of material costs, labor requirements, and equipment expenses. In this case, the task is to calculate these costs accurately for 20 steel doors in Phoenix, AZ, using specific framing materials.

Material Cost Calculation

The framing for each steel door is to be constructed using 8-inch steel channels, with each channel having a weight of 11.5 lb./LF. The first step is to determine the total length of channels required per door, based on framing design standards. Typically, a steel door frame consists of top, side, and sill components.

Assuming a conventional frame design, each frame comprises two vertical jambs, a top header, and a sill. For a 6' x 8' door, the perimeter encompasses 6' (72 inches) width and 8' (96 inches) height.

- Vertical jambs: 2 sides × 8' each = 16' (192 inches)

- Top header: 6' (72 inches)

- Sill: 6' (72 inches)

Total length of channels per door:

Total = 16' + 6' + 6' = 28' (336 inches)

Considering some additional length for overlaps, anchors, and bar stops—say approximately 10% extra—the adjusted total per door becomes:

28' × 1.10 ≈ 30.8' (370 inches)

For 20 doors:

Total length = 20 × 30.8' ≈ 616'

Using the weight per linear foot:

Weight per door = 30.8' × 11.5 lb./LF ≈ 354.2 lb.

Total material weight:

Total weight = 20 × 354.2 lb ≈ 7084 lb.

Assuming the current steel price in Phoenix, AZ, is approximately $0.60 per lb., the material cost:

Material cost = 7084 lb × $0.60/lb ≈ $4250.40.

Labor Cost Calculation

Labor costs depend on the rates applicable in Phoenix, AZ, for steel framing erection. Assuming a skilled labor rate of $60 per hour and an estimated installation rate of 10 linear feet per hour per worker. For the total length of 616 feet:

Total labor hours = 616 ft / 10 ft/hour ≈ 61.6 hours.

With a team of two workers:

Total labor cost = 2 × 61.6 hours × $60/hour ≈ $7392.

Equipment Cost Calculation

Equipment use includes portable torches, lifts, or scaffolds necessary for erecting steel frames. Suppose the equipment rental rates entail:

- Scaffold and lifting equipment: $50 per hour,

- Estimated duration: 10 hours,

then:

Equipment cost = 10 hours × $50/hour = $500.

Total Bare Cost Estimation

Adding all components:

- Materials: $4250.40

- Labor: $7392

- Equipment: $500

Total bare cost:

Total = $4250.40 + $7392 + $500 ≈ $14,142.40

This estimate does not include indirect costs such as permitting, overhead, and profit margins, aimed solely at the direct costs of materials, labor, and equipment for erecting the steel door frames.

CostWorks Format Presentation

The above calculations would be input into the CostWorks software format, specifying detailed quantities, unit costs, labor rates, and equipment costs, following standard CostWorks procedures for cost estimation. The data inputs include material weight per linear foot, total linear footage, labor productivity rates, and equipment rental costs, summing to arrive at the total bare cost.

Conclusion

Accurate cost estimation for steel door framing in Phoenix involves detailed calculations of material, labor, and equipment expenses, based on project-specific parameters and current regional costs. This process ensures a reliable and detailed estimate for project budgeting and bidding.
