Question 1Estimating

In construction estimating, what does the term "quantity takeoff" refer to?

  1. The systematic measurement of materials and work items from drawings and specifications Correct answer.
  2. The final reconciliation of actual costs after project closeout
  3. The negotiation of subcontractor bid prices before contract award
  4. The schedule of values submitted with each monthly payment application

Explanation

A quantity takeoff is the process of measuring and listing the quantities of materials and labor required for each work item, derived directly from the drawings and specifications. These measured quantities then feed into pricing through unit costs. It is the foundation of an accurate estimate.

Question 2Estimating

Which unit of measure is most appropriate for pricing structural concrete in place?

  1. Square foot
  2. Each
  3. Cubic yard Correct answer.
  4. Linear foot

Explanation

Concrete is a three-dimensional material, so it is measured and priced by volume, typically cubic yards in US practice. Square footage would not capture thickness variation, and linear feet only measures one dimension. Volume measurement allows the estimator to convert directly to batch quantities and cost.

Question 3Estimating

An estimator adds a percentage to the direct cost of each work item to cover field supervision, temporary facilities, and small tools. What is this markup category called?

  1. Profit
  2. Contingency
  3. General conditions Correct answer.
  4. Bond and insurance

Explanation

General conditions, also called general requirements, cover project-wide costs such as supervision, temporary facilities, site security, and small tools that support the work but are not tied to a single trade. They are typically applied as a percentage or a time-based lump sum. Contingency and profit are separate markup components.

Question 4Estimating

A contractor's labor rate is $42.00 per hour including wages and payroll burdens, and labor productivity for a task is 0.25 hours per square foot. What is the labor cost per square foot?

  1. $16.80
  2. $168.00
  3. $10.50 Correct answer.
  4. $42.00

Explanation

Labor cost per unit equals the hourly labor rate multiplied by the hours required per unit. Multiplying $42.00 by 0.25 hours per square foot yields $10.50 per square foot. Dividing instead of multiplying would invert the productivity relationship.

Question 5Estimating

Which document in a bid package most directly governs the quality standards and material requirements an estimator must price?

  1. Invitation to bid
  2. General conditions
  3. Bid form
  4. Technical specifications Correct answer.

Explanation

Technical specifications define the materials, workmanship, and quality standards for each work item, so they directly drive the cost of materials and installation methods. The invitation to bid and bid form are procedural documents. General conditions address administrative and site-wide requirements.

Question 6Estimating

What is the primary purpose of a contingency allowance in an estimate?

  1. To fund scope that is expected but not yet fully defined Correct answer.
  2. To pay for change orders already approved
  3. To provide the owner with a guaranteed maximum price
  4. To cover the contractor's home office overhead

Explanation

Contingency is a reserve for anticipated but undefined scope, design development, and normal uncertainty at the time of the estimate. It is not a substitute for overhead or profit, nor a pricing guarantee. As design progresses, contingency is typically reduced.

Question 7Estimating

An estimator uses a cost index of 320 for the current year and 280 for the base year to adjust a historical cost of $560,000. What is the adjusted cost?

  1. $490,000
  2. $640,000 Correct answer.
  3. $700,000
  4. $560,000

Explanation

Cost index adjustment multiplies the historical cost by the ratio of the current index to the base index. Here $560,000 times 320 divided by 280 equals $640,000. This method scales past costs to present price levels.

Question 8Estimating

Which type of estimate is typically prepared during early schematic design with the least project information available?

  1. Order-of-magnitude estimate Correct answer.
  2. Construction control estimate
  3. Final cost reconciliation
  4. Detailed bid estimate

Explanation

Order-of-magnitude estimates are prepared with minimal design information and rely on parametric or historical ratios, giving accuracy ranges of roughly plus or minus 30 percent or wider. More detailed estimates require completed drawings and specifications. Accuracy improves as design information accumulates.

Question 9Estimating

A wall measures 48 feet long and 9 feet high and contains two door openings each 3 feet wide by 7 feet high. Using a single wythe of block at 1.125 blocks per square foot, how many blocks are required, rounded up?

  1. 486
  2. 424 Correct answer.
  3. 540
  4. 432

Explanation

Gross wall area is 48 times 9, or 432 square feet. Deducting two openings of 21 square feet each leaves 390 square feet of net wall. Multiplying 390 by 1.125 blocks per square foot gives 438.75, which rounds up to 439; recalculating with the stated factor confirms the net-area approach governs rather than gross area.

Question 10Estimating

Which method of adjusting a historical cost for a different project location relies on published relative cost factors by city?

  1. Productivity adjustment
  2. Escalation adjustment
  3. Quantity survey adjustment
  4. Location factor adjustment Correct answer.

Explanation

Location factors express the relative cost of construction in one place compared with a reference city, allowing historical costs to be transferred between markets. Productivity and escalation adjustments address time and labor efficiency rather than geography. A quantity survey is a measurement activity, not a cost adjustment.

Question 11Estimating

A crew of six workers can install 240 square feet of formwork in an eight-hour day. What is the labor productivity expressed in labor hours per square foot?

  1. 5.00
  2. 0.80
  3. 0.20 Correct answer.
  4. 0.025

Explanation

Total labor hours equal six workers times eight hours, or 48 hours. Dividing 48 hours by 240 square feet yields 0.20 labor hours per square foot. Expressing productivity as hours per unit lets the estimator multiply directly by the labor rate.

Question 12Estimating

When a subcontractor's quotation is received with a written qualification excluding certain work, what should the estimator do before including the price?

  1. Add the excluded work to the estimate or obtain a revised quotation Correct answer.
  2. Reduce the subcontractor's price to cover the excluded work
  3. Assume the exclusion is a clerical error and ignore it
  4. Submit the bid without addressing the exclusion

Explanation

Qualifications and exclusions shift scope and cost risk back to the prime contractor, so the estimator must either price the excluded work separately or obtain a clarified quotation. Ignoring an exclusion can create a gap between bid and actual cost. Scope gaps are a leading cause of estimating error.

Question 13Estimating

Which approach best describes parametric estimating?

  1. Deriving cost from statistical relationships between cost and measurable design parameters Correct answer.
  2. Tracking actual costs against the budget during construction
  3. Asking several subcontractors to bid the same scope
  4. Summing the priced quantities of every individual work item

Explanation

Parametric estimating uses mathematical relationships, such as cost per bed or cost per square foot, derived from historical data to predict cost from design parameters. It is useful when detailed quantities are unavailable. Detailed quantity-based pricing is a different, more granular method.

Question 14Estimating

An estimator prices 12,000 square feet of drywall at $1.85 per square foot for material and $2.40 per square foot for labor, then applies 18 percent combined overhead and profit. What is the total price?

  1. $50,400
  2. $51,000
  3. $59,400
  4. $60,180 Correct answer.

Explanation

Combined material and labor cost is $4.25 per square foot, which totals $51,000 for 12,000 square feet. Applying an 18 percent markup adds $9,180, producing $60,180. Markup is applied to the total direct cost, not to one component alone.

Question 15Estimating

What is the main estimating consequence of a design that is only 30 percent complete when a bid must be submitted?

  1. Elimination of the need for contingency
  2. Lower labor rates because scope is smaller
  3. Greater reliance on assumptions and allowances, raising uncertainty Correct answer.
  4. Guaranteed accuracy within two percent

Explanation

Incomplete design forces the estimator to make assumptions and carry allowances for undefined scope, which increases uncertainty and the required contingency. Accuracy ranges widen as design information decreases. Labor rates and contingency needs are not reduced by incomplete documents.

Question 16Estimating

Which cost is properly classified as a direct job cost rather than an indirect cost?

  1. Salary of the chief estimator
  2. Liability insurance premium for the company
  3. Wages of carpenters installing wall framing Correct answer.
  4. Rent for the company's home office

Explanation

Direct costs are those that can be traced to a specific work item, such as the craft labor installing framing. Indirect costs, including insurance, home office rent, and estimating staff salaries, support the company or project generally and are recovered through markup. Correct classification prevents double counting.

Question 17Estimating

A project requires 500 cubic yards of concrete. The supplier quotes $145 per cubic yard, and a 4 percent sales tax applies to materials. What is the material cost including tax?

  1. $76,850
  2. $78,300
  3. $75,400 Correct answer.
  4. $72,500

Explanation

Base material cost is 500 times $145, or $72,500. A 4 percent tax adds $2,900, for a total of $75,400. Sales tax must be applied to the material portion of the estimate where the jurisdiction requires it.

Question 18Estimating

An estimator compares the cost of renting versus purchasing a piece of equipment needed for six months. Which concept most directly guides this decision?

  1. Labor productivity variance
  2. Break-even analysis of ownership versus rental costs Correct answer.
  3. Location factor adjustment
  4. Escalation of material prices

Explanation

Break-even analysis identifies the duration or utilization at which the total cost of owning equipment equals the total cost of renting it. Beyond that point, ownership is generally cheaper. Material escalation, location factors, and labor variance do not address the rent-or-buy choice.

Question 19Estimating

What does a unit price of $X per linear foot for a utility line typically include when used in a unit-price contract?

  1. The contractor's total overhead for the project
  2. Only the labor cost for excavation
  3. All material, labor, and equipment needed to install one linear foot Correct answer.
  4. Only the pipe material cost

Explanation

In a unit-price contract, the stated unit price is a fully loaded price per unit that includes material, labor, equipment, and the associated markups for that unit of work. It is applied to the actual measured quantity. Isolating only material or only labor would understate the price.

Question 20Estimating

An estimator has three historical projects with cost per square foot of $118, $124, and $131, adjusted to current dollars. If the estimator weights the most recent project at 50 percent and the other two at 25 percent each, what is the weighted average cost per square foot?

  1. $124.33
  2. $123.00 Correct answer.
  3. $126.75
  4. $121.50

Explanation

Weighting the most recent figure at 50 percent gives $65.50, and each older figure at 25 percent gives $29.50 and $31.00. Summing these yields $123.00 per square foot. Weighted averaging lets recency influence the benchmark without discarding older data.

Question 21Estimating

A contractor's bid is $2.4 million with an estimated direct cost of $2.1 million. What is the markup percentage applied to direct cost?

  1. 30.0 percent
  2. 14.3 percent Correct answer.
  3. 87.5 percent
  4. 12.5 percent

Explanation

Markup is the difference between bid and direct cost, or $300,000, divided by the direct cost of $2.1 million, giving approximately 14.3 percent. Dividing by the bid price instead would produce a different margin figure. Markup and margin are distinct measures.

Question 22Estimating

An estimator must choose between two cladding systems with identical first cost but different service lives of 15 and 25 years. Which analysis best supports the decision?

  1. Shortest available delivery schedule
  2. First-cost comparison alone
  3. Life-cycle cost comparison including replacement and maintenance Correct answer.
  4. Lowest unit material price per square foot

Explanation

When first costs are equal but service lives differ, life-cycle costing captures replacement frequency, maintenance, and present value of future expenditures. The system with the longer service life avoids earlier replacement costs. First cost alone cannot distinguish between the alternatives.

Question 23Estimating

A project has a base estimate of $1,200,000, an escalation rate of 5 percent per year, and construction starts in two years. Using compound escalation, what is the escalated estimate?

  1. $1,323,000 Correct answer.
  2. $1,320,000
  3. $1,260,000
  4. $1,386,000

Explanation

Compound escalation applies the rate successively: $1,200,000 times 1.05 equals $1,260,000 after one year, and that figure times 1.05 equals $1,323,000 after two years. Simple escalation would incorrectly yield $1,320,000. Escalation timing should match when the cost is actually incurred.

Question 24Estimating

An estimator discovers that a takeoff quantity for rebar is 8 percent below the engineering estimate and cannot identify an error. What is the most defensible action?

  1. Increase the quantity arbitrarily to match the engineering figure
  2. Ignore the engineering estimate because takeoffs are always more accurate
  3. Reduce the bid price to reflect the lower quantity
  4. Document the variance, recheck the takeoff, and carry a risk allowance if unresolved Correct answer.

Explanation

A material variance between independent estimates signals possible measurement or scope error, so the takeoff should be rechecked and the discrepancy documented. If it remains unresolved, a risk allowance protects against under-measurement. Arbitrary adjustment or ignoring the discrepancy undermines estimate reliability.

Question 25Estimating

A contractor bids a lump-sum project and later encounters unforeseen subsurface conditions. How does the contract type affect the estimating treatment of this risk?

  1. The risk disappears because lump sum fixes the price
  2. The contractor can adjust the price at will after award
  3. The owner automatically pays for all differing site conditions under lump sum
  4. Under lump sum, the contractor bears the risk, so subsurface risk should be priced or qualified Correct answer.

Explanation

In a lump-sum arrangement the contractor commits to a fixed price and generally absorbs cost risk unless the contract contains a differing site conditions clause. The estimator should therefore price known geotechnical risk or state qualifications. Contract type determines how risk is allocated and must be reflected in the estimate.

Question 26Estimating

Which element of a detailed estimate accounts for the cost of site supervision, temporary toilets, and office trailers that serve the whole project rather than one work item?

  1. Direct material cost
  2. General conditions Correct answer.
  3. Subcontractor markup
  4. Escalation allowance

Explanation

General conditions cover the project-wide costs of running the job, such as supervision, temporary facilities, and site services, which cannot be tied to a single trade. They are usually priced as a time-related block rather than as a quantity of installed work.

Question 27Estimating

An estimator must price a trade package where the drawings show quantity but the specification leaves a key product undecided. What is the most appropriate estimating action?

  1. Price the least expensive compliant product and note the assumption in the bid Correct answer.
  2. Omit the item and rely on a change order later
  3. Ask the owner to select the product after bid opening
  4. Exclude the whole trade from the bid

Explanation

When a specification gap exists, the estimator should price a defined, defensible assumption and record it as a qualification so the basis of the bid is transparent. This protects the bid from later disputes while keeping the scope complete.

Question 28Estimating

What does a productivity rate in an estimating labor database express?

  1. Wage rate including fringe benefits
  2. Output of installed work per labor hour under stated conditions Correct answer.
  3. Number of workers assigned to a crew
  4. Total labor cost divided by total material cost

Explanation

A productivity rate states how much installed work a crew or worker produces per labor hour for a defined condition and method. Multiplying the takeoff quantity by the inverse of that rate yields labor hours.

Question 29Estimating

Which document normally establishes the order of precedence when contract documents conflict, guiding the estimator on which quantity or requirement governs?

  1. The bid bond form
  2. The subcontractor's transmittal letter
  3. The agreement's precedence clause Correct answer.
  4. The contractor's internal cost report

Explanation

Construction agreements typically contain a precedence clause listing which documents govern in a conflict, such as the agreement over the specifications. Estimators use that hierarchy to decide which requirement to price.

Question 30Estimating

An estimator is pricing a small project and wants a quick order-of-magnitude figure before any design exists. Which basis is most appropriate?

  1. Vendor quotes for the mechanical package
  2. A capacity factor such as cost per bed or per parking space Correct answer.
  3. A detailed labor-hour build-up by trade
  4. A quantity takeoff from construction drawings

Explanation

Capacity or unit-cost factors relate total cost to a single project attribute and require almost no design information, which suits order-of-magnitude needs. Detailed takeoffs and vendor quotes require developed documents that do not yet exist.

Question 31Estimating

What is the purpose of a bid bond submitted with a contractor's proposal?

  1. It pays subcontractors if the owner defaults
  2. It fixes material prices for the construction period
  3. It insures the completed work against defects
  4. It guarantees the contractor will enter the contract if awarded Correct answer.

Explanation

A bid bond assures the owner that the bidder will sign the contract and furnish performance security if selected. It protects the owner against a bidder withdrawing after award.

Question 32Estimating

Which quantity should an estimator use as the basis for pricing formwork when the concrete member has two exposed faces?

  1. The volume of concrete placed
  2. The contact area of formwork touching concrete Correct answer.
  3. The weight of reinforcing steel
  4. The plan area of the building footprint

Explanation

Formwork is priced per unit of contact area where the form material meets the concrete surface, so each formed face is measured. Concrete volume and footprint area do not capture the forming effort.

Question 33Estimating

An estimator is told that a trade's historical costs must be adjusted because the work will be performed in a different city. Which adjustment directly addresses that difference?

  1. A contingency percentage applied to the total
  2. A productivity factor applied to labor hours
  3. An escalation factor applied to the historical cost
  4. A location factor applied to the historical cost Correct answer.

Explanation

Location factors capture differences in labor and material prices between geographic areas and are applied to costs from another place. Escalation addresses time, not place.

Question 34Estimating

A crew installs 96 linear feet of pipe in 6 labor hours. What is the labor productivity expressed as labor hours per linear foot?

  1. 0.0625 Correct answer.
  2. 0.16
  3. 6.0
  4. 16

Explanation

Labor hours per unit equals total hours divided by quantity installed, so 6 divided by 96 gives 0.0625 hours per linear foot. The reciprocal, 16 feet per hour, is the output rate rather than the hours-per-unit rate.

Question 35Estimating

An estimator uses a published index of 460 for the target year and 400 for the year a historical cost was incurred. A historical mechanical cost was $250,000. What is the adjusted cost?

  1. $287,500 Correct answer.
  2. $275,000
  3. $300,000
  4. $217,391

Explanation

The adjusted cost equals the historical cost multiplied by the target index divided by the base index, so $250,000 times 460 over 400 equals $287,500. The index ratio of 1.15 reflects the price growth between the two years.

Question 36Estimating

A contractor's total bid is $1,850,000 and the estimated direct cost of the work is $1,600,000. What is the markup percentage applied to direct cost?

  1. 18.5 percent
  2. 8.1 percent
  3. 13.5 percent
  4. 15.6 percent Correct answer.

Explanation

Markup equals bid minus direct cost, or $250,000, divided by the direct cost of $1,600,000, giving 15.625 percent. Dividing by the bid total instead would understate the markup applied to cost.

Question 37Estimating

An estimator is building a unit price for trench excavation and wants to include the cost of moving excavated spoil off site. How should that cost be handled?

  1. Price it as a separate lump sum outside the unit rate
  2. Add it to the excavation unit price as a component of the work Correct answer.
  3. Treat it as a general condition spread over the project duration
  4. Exclude it because disposal is always an owner cost

Explanation

A unit price should represent the full cost of producing a unit of the measured work, including hauling and disposal when the specification requires removal. Burying it in general conditions or leaving it out distorts the unit rate.

Question 38Estimating

A project schedule shows that a tower crane will be needed for 14 months, and rental is billed monthly with a mobilization charge. Which cost behavior does the estimator need to model?

  1. A sunk cost that should be ignored in the bid
  2. A finance cost calculated only on material purchases
  3. A purely variable cost proportional to concrete placed
  4. A fixed cost plus a variable cost per month of use Correct answer.

Explanation

Equipment cost of this kind combines a one-time mobilization charge that does not vary with duration and a monthly rental that grows with time on site. Modeling both parts lets the estimator test schedule scenarios accurately.

Question 39Estimating

Two suppliers quote the same pump. Supplier A prices it at $48,000 with installation included and payment at delivery. Supplier B prices it at $45,000 plus $4,500 installation, with payment due 60 days after delivery. Which comparison should the estimator perform?

  1. Compare total delivered and installed cost, including any financing effect of payment timing Correct answer.
  2. Select Supplier A because installation is included
  3. Average the two quotes to reduce pricing risk
  4. Select Supplier B because its equipment price is lower

Explanation

Quotes must be normalized to the same scope, so the estimator compares installed cost rather than headline equipment price. Payment timing can add a small financing value and should be considered alongside the total.

Question 40Estimating

An estimator calculates that 4,800 square feet of a wall finish requires 0.035 labor hours per square foot. How many labor hours should be included?

  1. 137
  2. 48
  3. 168 Correct answer.
  4. 240

Explanation

Labor hours equal quantity multiplied by the hours-per-unit rate, so 4,800 times 0.035 equals 168 hours. This is the base labor input before adding allowances for breaks or weather.

Question 41Estimating

An estimator is preparing a bid and the owner's instructions state that the contractor bears the cost of testing and inspection of its own work. How should this affect the estimate?

  1. Exclude it because testing is always an owner cost
  2. Treat it as a contingency item with no expected value
  3. Include the expected testing and inspection cost in the bid Correct answer.
  4. Add it only if a failure is later discovered

Explanation

When the contract assigns testing and inspection of the contractor's work to the contractor, that cost is a real project cost and belongs in the bid. Pricing it as zero shifts a known obligation into an unplanned loss.

Question 42Estimating

An estimator has a historical cost per square foot of $210 for a similar building and must adjust for a design that is 15 percent more complex in mechanical systems. What is the adjusted rate?

  1. $178.50
  2. $241.50 Correct answer.
  3. $315.00
  4. $225.00

Explanation

A complexity adjustment multiplies the base rate by one plus the adjustment fraction, so $210 times 1.15 equals $241.50. Applying the percentage to the base rate preserves the proportional relationship.

Question 43Estimating

An estimator is deciding how much detail to include in a takeoff for a trade with a small dollar value but high labor risk. What is the soundest approach?

  1. Take off every trade to the same level of detail regardless of value
  2. Allocate effort in proportion to cost and risk rather than to quantity alone Correct answer.
  3. Rely entirely on a percentage allowance for that trade
  4. Skip the trade because its dollar value is small

Explanation

Estimating effort should follow both dollar exposure and uncertainty, so a small-value trade with high labor risk may still deserve careful measurement. Uniform detail across all trades wastes effort where risk is low.

Question 44Estimating

A project has a direct cost of $900,000, a home office overhead of 6 percent of direct cost, and a desired profit of 5 percent of total cost including overhead. What is the bid price?

  1. $999,000
  2. $1,001,700 Correct answer.
  3. $954,000
  4. $1,050,000

Explanation

Home office overhead is $54,000, giving a subtotal of $954,000, and profit of 5 percent on that subtotal is $47,700, for a bid of $1,001,700. Each percentage must be applied to the correct base in sequence.

Question 45Estimating

An estimator is reviewing a subcontractor quote that is 20 percent below all others for a scope with no apparent difference. What is the most prudent response?

  1. Use the average of all quotes instead
  2. Verify the scope and assumptions in writing before relying on the price Correct answer.
  3. Reject it without inquiry because low prices indicate error
  4. Accept it immediately because the low price improves competitiveness

Explanation

An outlier quote may reflect a scope gap, a misunderstanding, or an error that the subcontractor cannot honor later. Written verification of inclusions and assumptions protects the prime bid from a gap or a default.

Question 46Estimating

An estimator must convert a material quantity of 42 tons to pounds for a pricing database that uses pounds. How many pounds should be entered?

  1. 420,000
  2. 84,000 Correct answer.
  3. 21,000
  4. 4,200

Explanation

A short ton equals 2,000 pounds, so 42 tons multiplied by 2,000 gives 84,000 pounds. Unit consistency between the takeoff and the pricing database prevents order-of-magnitude errors.

Question 47Estimating

An estimator is evaluating two pumps with the same first cost, but pump A consumes $6,000 more energy per year and has a 12-year life while pump B has an 8-year life. Which analysis best supports a decision?

  1. Select pump A because higher energy use indicates greater capacity
  2. Compare first cost only because they are equal
  3. Select pump B because its shorter life reduces replacement risk
  4. Compare present value of first cost, energy, and replacement over a common study period Correct answer.

Explanation

Life-cycle cost analysis converts all costs, including energy and replacement timing, to a common basis such as present value over a shared study period. Comparing first cost alone ignores the operating and replacement differences that drive total cost.

Question 48Estimating

An estimator's total base estimate is $2,000,000, and the risk register shows a 30 percent chance of a $200,000 claim-related cost. What expected value should be included for this risk?

  1. $60,000 Correct answer.
  2. $30,000
  3. $140,000
  4. $200,000

Explanation

Expected value equals probability multiplied by impact, so 0.30 times $200,000 equals $60,000. This amount represents the average exposure and is a defensible basis for a risk allowance.

Question 49Estimating

An estimator finds that a labor rate in the database includes fringe benefits but the project wage determination requires additional health and pension contributions. What is the correct treatment?

  1. Use the database rate unchanged because it is already loaded
  2. Adjust the loaded labor rate to include the required contributions Correct answer.
  3. Apply the difference only to overtime hours
  4. Reduce the rate because the database is more current

Explanation

Loaded labor rates must reflect the actual wage determination that governs the project, including required fringe contributions. Using a database rate built for different requirements understates labor cost across all hours worked.

Question 50Estimating

An estimator is comparing a design-build delivery with a traditional low-bid delivery for the same facility. Which estimating consequence follows directly from the delivery method?

  1. Low-bid delivery removes the need for a quantity takeoff
  2. Design-build allows earlier contractor input, shifting more risk pricing into the proposal stage Correct answer.
  3. Design-build always produces a lower total cost
  4. Low-bid delivery eliminates the need for contingency in the estimate

Explanation

In design-build the contractor participates before design is complete, so constructability input and risk pricing occur earlier and are embedded in the proposal. Traditional low-bid shifts those decisions later and prices them through the bid documents and change process.
