A complete BU 442 Unit 2 cost estimate with basis: every line carrying its method, input source and assumption, closed by stated exclusions and a confidence range. Searches like "bu 442 unit 2 assignment example", "bu442 unit 2 sample" and "bu 442 unit 2 example" land here.
What a finished BU 442 Unit 2 cost estimate with basis looks like
Two documents sit together here, and the second is longer than the first. The estimate itself is a table of cost elements with quantities, unit rates and extended amounts, subtotaled by the part of the work each belongs to and carrying labor, materials, equipment and any purchased service in separate lines rather than merged. The basis document follows and does the grading work: for every element, which estimating method produced it, what the input was and where it came from, what has been assumed about quantity or productivity, and how firm that assumption is. Exclusions get their own list, since an estimate is defined as much by what it leaves out. A confidence statement closes the pair, giving a range rather than a single total and saying which elements are driving the width.
How a BU 442 Unit 2 example is structured
Quantities are separated from rates in every line, because an estimate that shows only a total per element hides which half is uncertain and cannot be corrected when one of them changes. Cost types stay in their own rows so that a labor rate revision does not require the whole element to be rebuilt. The basis is written element by element rather than as one paragraph at the front, since a general note about method tells a reader nothing about the line they are questioning. Assumptions are stated in a form that could be proved wrong, which is what makes them worth writing down. Exclusions come before the confidence statement because a narrow range around an estimate missing whole scope areas is misleading. The range is derived from the elements themselves, and the widest contributors are named so the reader knows where to push.
Quantity and rate kept apart
Each line shows how much and how much each, so a reader can challenge one without having to rebuild the other.
A basis line for every element
Method, input, source and assumption are recorded per element rather than summarized once, because questions arrive about single lines.
Assumptions written so they could fail
Each assumption is phrased as something a later fact could contradict, which is the only form that makes it useful to record.
Exclusions listed as a deliverable
What the estimate does not cover gets its own section, since scope left unpriced is the commonest source of a later overrun.
A range instead of one total
The estimate closes with a span and names the elements whose uncertainty makes it wide, rather than presenting a single confident figure.
Where marks go in BU 442 Unit 2
Estimates lose credit when the basis is missing or generic. A table of numbers with no accompanying document leaves a marker unable to tell a reasoned figure from a guess, and the basis is usually where most of the points sit. One paragraph saying the estimate used industry standards covers every line and explains none of them. Rates presented as market facts, rather than as inputs belonging to the constructed case, cross into inventing data. Elements priced as a lump with no quantity behind them cannot be revised when the quantity changes. Estimates with no exclusions imply total coverage that no estimate has. Totals given to the dollar from assumed productivity claim a precision the inputs cannot support. A rate card or vendor quotation held at work belongs to the employer who obtained it.

BU 442 Unit 2 questions, answered
Where do the rates come from if the project is invented?
From reasoning you show on the page. Publicly published wage series and vendor list prices can be cited where you genuinely have them, and everything else is a figure you construct and label as case material. What matters to the criterion is that each rate has a visible origin. A number with no stated source reads the same whether it was researched or chosen to make the total look tidy.
How detailed does the estimate need to be?
Detailed enough that every line can be argued with, which is usually fewer elements than a first draft assumes. Twenty lines each carrying a quantity, a rate and a basis beat sixty lines of names and totals. Where the instructions fix a level of decomposition, follow it; where they do not, stop when a further split would produce elements you cannot estimate any better.
Does the basis need to cover every single line?
Every line the reader could question, which in practice means all of them at this level of detail. Where several elements share a method and a source, group them under one basis entry and say which lines it covers rather than repeating the same paragraph. What fails is a basis that covers the large elements and leaves the rest unexplained, since the unpriced assumptions are often in the small ones.
