Construction Cost Estimating Purdue University Global Free custom sample in 24 to 48h

Thirty-eight thousand four hundred square feet of community recreation center, priced from a cost database's median of 312 dollars a square foot, then scaled by a city index of 91.6 and a time factor of 1.036, reaches 14,871,295 dollars in the MT382 Unit 2 conceptual estimate. The total is stated as a range, labeled Class 5 and dated.

What this page holds

An adjusted database median times floor area, a site allowance and 20 percent design contingency give MT382's Unit 2 estimate: 14.87 million, stated as 11.9 to 20.8 million. Searches like "mt 382 unit 2 assignment example", "mt382 unit 2 sample" and "mt382 unit 2 example" land here.

What a finished MT382 Unit 2 conceptual estimate looks like

A program summary opens the five pages: a two-story recreation center of 38,400 gross square feet with a two-court gymnasium, an elevated walking track, fitness and multipurpose rooms, and locker rooms, for a composite parks district that has neither chosen a site nor commissioned a survey. The cost sheet follows in six lines: the database median of 312 dollars per square foot, multiplied by the city index ratio of 0.916 and a time factor of 1.036 to give 296.08; building cost of 11,369,492; a site allowance at 9 percent, 1,023,254; design contingency at 20 percent, 2,478,549; and a total of 14,871,295, or 387.27 per square foot. A range statement, an exclusions list naming each item left out, and a basis-of-estimate paragraph fill the final pages.

How a MT382 Unit 2 example is structured

Every figure traces to a single source line, because at this stage the method is the estimate. The database median is used rather than a quartile, and the paper says why: the program resembles a typical center, with no pool and no unusual structure. Quartiles then set the spread. At 268 and 371 dollars they sit 14.1 percent below and 18.9 percent above the median, and the stated range is wider still, minus 20 to plus 40 percent, because the site has no survey, no borings and no utility information. Site work is a percentage of building cost, labeled as a placeholder. Design contingency sits on its own line instead of inside the rate. Exclusions come last and are specific: land, design fees, furniture and equipment, utility company charges, and escalation beyond the estimate date, which a later memo prices.

Six lines of arithmetic

Median, city ratio, time factor, building cost, site allowance, design contingency. A board member with a calculator can reproduce 14,871,295 dollars from the sheet without asking anyone.

The median, and the reason for it

The program resembles an ordinary community center: two courts, a track, fitness and meeting space, no pool. Reaching for the upper quartile without such a reason would inflate the figure by guesswork.

A range wider than the quartiles

Quartiles alone suggest minus 14 to plus 19 percent. No survey, borings or utility locations exist yet, so the estimate states minus 20 to plus 40, from 11.9 to 20.8 million.

Site work as a placeholder

Nine percent of building cost, 1,023,254 dollars, stands in for parking, utilities and grading until a site is chosen. The sheet labels it an allowance, not a price.

What the number leaves out

Land, design fees, furniture, fitness equipment, utility company charges and escalation past the estimate date. Each exclusion is listed so nobody reads the total as a project budget.

Where marks go in MT382 Unit 2

Deductions in this unit gather around false precision. A conceptual total printed to the last dollar, with no band around it, looks like a bid, and most sections expect the accuracy range stated and justified by what is still unknown. The method must suit the information: a square-foot figure fits a program with no drawings, while pretending to detailed quantities does not. Rates without a source, or a database figure applied with no location or time adjustment, cost steadily. Contingency buried inside the rate hides the one line an owner needs to watch shrink. Site work omitted because it sits outside the building footprint is a frequent gap. An exclusions list reading only soft costs leaves the reader guessing; naming each exclusion shows the estimator knew where the figure stopped.

Get a MT382 Unit 2 example written to your instructions

A conceptual estimate needs only a program, so the floor area, building type and location from the Unit 2 prompt suffice to start, with any cost data the course supplies and the rubric. Yours is free the first time, delivered in 24-48h, the rate adjusted for place and date, contingency visible, and a range in place of one total.

MT382 Unit 2 questions, answered

Which cost per square foot should a conceptual estimate use?

Usually the median for the building type from the cost data your course supplies, unless the program gives a reason to move toward a quartile, such as a pool or an unusually tall gym. State the reason either way. Then adjust for location and date before multiplying by the floor area.

Why present a range instead of one number?

Because a figure built from area alone cannot support one number. Quartile spreads in the cost data give a starting band, and site or program unknowns widen it. A range tells the owner how much the figure could move; a single total invites the owner to treat it as a budget.

Should design contingency be included at this stage?

Yes, on its own line. Early figures carry the largest design contingency because the least has been drawn, often well above later stages. Keeping it separate lets the owner watch it fall as drawings develop, and avoids hiding it inside a rate where nobody can see or question it.
