Estimating – The Concrete Canoe Center (CCC)

The concrete canoe team at CUA has just learned that after many discussions within the university, funding for a new state-of-the-art engineering student facility shall finally be allocated. Ever since hosting the national concrete canoe competition on campus in Summer of 2004, the School of Engineering has made support for this design and construction team effort a priority and thus has recently approved the preliminary design.

Plan documents call for construction of a single-story structure located directly along the rear walls of the existing Pangborn Hall, thus expanding its basement level. The new center will provide space for design, construction, testing, and storage of future vessels, and for paddling training of the student team members. The School of Engineering believes that this facility will bring together current students in a common learning effort as well as assist in attracting the best potential students to the university.

The Facilities Planning and Construction office of the university has asked your company to prepare a preliminary estimate for the CCC project. As a recent CUA civil engineering graduate, you are feeling honored to have been selected and get to work.

Dimensions and a description of the structural system extracted from the plan drawings are provided in Table 1, design features in Table 2, and Materials in Table 3.

Table 1: Dimensions and Structural System of Planned CCC

Item	Dimensions
Height	15.5 ft
Width	19.5 ft
Length	144 ft
Segmentation	8 units longitudinally, identical to rear side of Pangborn Hall.
Structural System	18 x columns 1.5 ft x 1.5 ft 9 x transverse beams 2 ft high x 1.5 ft wide 1 x Floor slab 1 ft thick as slab-on-grade foundation, with 1 ft x 1 ft footing under the edge of the slab Longitudinal beams 18 ft long, at 6.5 ft distance center-to-center

The transverse beams will connect pairs of columns in the North-South direction. The longitudinal beams will be placed on top in the East-West direction. Roof sheets will be placed on top of the longitudinal beams to enclose the structure.

A site survey shows that 650 cy of earthwork and landscaping are needed to excavate for the floor slab, pool, and foundations, and to reconstruct the parking lot embankment. A backhoe loader will be used to load a truck that will move all soil material.

Table 2: Design Features of Planned CCC

Item	Description
Access	Large double-doors on East side, 15 ft wide x 10 ft high. 2 sets of double-doors on North side, 8 ft wide x 7 ft high each.
Construction Lab	In West end, including overhead storage racks. Interior drywall will be estimated and constructed at a later date.
Test Pool, inside dimensions	Depth 6 ft, width 10 ft, length 100 ft   Pool has a rectangular trough shape with 1 ft wall and floor thickness. Pool is positioned approximately centered in and underneath the floor slab. Filter and pump system will be installed. Wave maker unit and flow sensors will be purchased at a later date.

Table 3: Materials for Planned CCC

Item	Material
Columns	Reinforced concrete
Transverse beams	Reinforced concrete
Longitudinal beams	Steel profiles
Floor Slab	Reinforced concrete
Roof	Corrugated sheet metal with asphalt coating
Walls	50 % of the wall area will be glass panels 50 % of the wall area will be concrete blocks with brick facing

From your estimating manuals and your company’s estimating database you obtain the following current cost and productivity information for crews and equipment:

Table 4: Costs and Productivity for Planned CCC

Item	Description	Cost	Productivity
Material	Reinforced concrete including formwork and shoring, etc.	66.74 $/cy	N/A
Steel beams including scaffolding, etc.	11.89 $/ft	N/A
Corrugated sheet metal with asphalt coating	3.53 $/sf	N/A
Glass panels including frames, fixtures, etc.	17.53 $/sf	N/A
Concrete blocks and brick facing including ties, mortar, etc.	4.89 $/sf	N/A
Equip-ment	Backhoe Loader, including fuel, etc.	47.00 $/h	35 cy/h
Dump Truck, including fuel, etc.	53.00 $/h	20 cy/h
Crane Truck, including fuel, etc. for beams, for sheet metal	39.00 $/h 39.00 $/h	160 ft/h 300 sf/h
Labor	Equipment Operator	27.60 $/h	N/A
Concrete Worker	20.90 $/h	0.5 cy/h
Glazier	23.20 $/h	20 sf/h
Stone Mason	24.40 $/h	30 sf/h
Steel Subcontractor	28.10 $/h	80 ft/h
Superintendent	27.00 $/h	N/A
Miscell-aneous	Mobilization and demobilization	500 $/EA	N/A
Large double-doors, 15 ft wide by 10 ft high	789 $/EA	N/A
Double-doors, 8 ft wide by 7 ft high	434 $/EA	N/A
Waterproofing of test pool	$20,000	N/A
Filter and pump system	$14,750	N/A
Storage racks, including installation	$1,800	N/A
Insulation materials	$8,000	N/A
Consumables	$1,000	N/A

Fringe benefits are at 15% of the labor costs. One superintendent will continuously be present on site. Home office overhead costs are at 10% of total construction costs. The facility will be constructed a year from now and you estimate the inflation rate at 3.75 %. You will use one backhoe loader and one dump truck for earthwork, and one crane for placing steel beams for the roof. You may consider a scrap/waste factor and an efficiency factor to have a more realistic estimate.

Please prepare a submittal including the following:

• Memorandum containing: (a) Project description (b) estimate summary, clearly stating the estimated labor, equipment, and materials costs, and the total costs, and (c) important assumptions that needed to be made reasonably based on engineering judgement and their justification;
• Sketches as needed (not required, but highly recommended);
• Quantity sheet with all data, calculations, and cost codes;
• Pricing sheet with all data, calculations, and cost codes.
