(The coefficient for m should be 3, not 2.) correction Page 59-7, second column, second paragraph of part (c): The last sentence reads "From App. 59.A, C b = 3." The value 3 should be.3. (The equations that follow use the correct value of.3.) correction First column, Sec. 8, 5th line: "...it is 24 lbf/in 2..." should be "...it is 24,000 lbf/in 2..." correction Second column, "I n = 334 in 4 /fti n = in 4 /ft", as the incorrect value was read from App. 68.A. This will change Ex and 68.4 slightly correction Second column, Eq. 20., second and third line: Change "00" to "(60 min/hr)", since the NRCS Lag Equation determines the time of concentration in hours correction Table 35.5, fine-grained, low compressibility: "(liquid limit 50 or more)(liquid limit less than 50)" The parenthetical comment below for the high compressibility soils is correct. Second column, two things: () third paragraph, 2/3 down: "...known as the K-rail) is 52 in tall." should be "...known as the K-rail) is 32 in tall." (2) A 42-in /5

2 3/7/2 Errata Search Results correction "...known as the K-rail) is 32 in tall." (2) A 42-in version of the Jersey barrier, similar to the Ontario Barrier in design, is known as the "Jersey heavy vehicle median divider". This is what is illustrated in Fig However, the Fig. 74. could also be labeled as "Ontario Barrier" correction Second column, first line: "..relations are approxmiate...relations are approximate...". First column, Eq : " correction " correction First column, Eqs and 37.28, BOTH: This affects Ex. 37., effectively reversing the horizontal and vertical values. First column, Eq : " correction ". First column, Sec. 5, middle of second paragraph: " correction (equivalent to )..". should be "...(equivalent to )..." Second column, end of Ex. 7.4, in the calculation of h f : " correction " in the formula. In the actual calculation the correct exponent has been used correction Section 7, second paragraph: there should be a space between "MSJCC and Chap. 2" and between 2/5

3 3/7/2 Errata Search Results correction space between "MSJCC and Chap. 2" and between "MSJCC and Chap. 3." correction Second column, Sec. 4, 3rd paragraph: "30-milPVC costs less...30-mil PVC costs less..." 60-3 correction Second column, Table 60., note (b) below the table: " " correction First column, middle of page: "...from App. 22.D..." should be "...from App. 22.C..." correction Second column, in Solution to Ex. 28.2: "From App. 22.D...From App. 22.C..." correction Second column: The logic used to solve Ex is incorrect. The 4/3 multiplier only affects the Strip Forms activity, since the other two activities only require 3 carpenters. With 3 carpenters, stripping the forms will take (4/3)(0 days) = 3.3 days, versus the 0 days required with 4 carpenters. The increase is 3.3 days - 0 days days correction Second column, end of Sec. 47: "...located hear street corners...located near street corners..." 28-9 correction First column, two lines above Eq : "HCO 3 ) concentration ) in mg/lhco 3 concentration) in mg/l". (Remove extra parenthesis.) 49-8 correction Second column, in the square bracketed quantity for Eq. 49.3(b): When following solution for Example 7.2, friction factor is determined to be using Figure 7.4. However, I cannot arrive at the same result using Figure 7.4 as shown. The curve for relative roughness = will not allow a result less than.02 for Re =.8 x 0E correction Response from Author: The solution makes use of App. 7.B to get If you used Fig. 7.4, you'd get a value of 0.02, which 3/5

4 3/7/2 Errata Search Results you used Fig. 7.4, you'd get a value of 0.02, which would be fine for the exam. There are several versions of the "Moody" chart, and newer ones make use of the same equations that App. 7.B was generated from. The differences are minor, and 3- digit accuracy is illusory. The solution to Ex should be as follows: Consider wall. The cost per foot of wall is $9000/50 ft. According to Eq , accuracy of cost data is proportional to wall length, (i.e., cost per foot from a wall of length 2X is twice as reliable as cost per foot from a wall of length X), this cost per foot value is given a weight of 50 ft/(50 ft + 90 ft + 65 ft). So, the weighted cost per foot for wall is 86-3 correction w C ft, = (50 ft)($9000/50 ft)/(50 ft + 90 ft + 65 ft) = ($9000)/(50 ft + 90 ft + 65 ft). Similarly, the weighted cost per foot for wall 2 is w 2 C ft,2 = ($5000)/(50 ft + 90 ft + 65 ft), and the weighted cost per foot for wall 3 is w 3 C ft,3 = ($,000)/(50 ft + 90 ft + 65 ft). From Eq , the total weighted cost per foot is C ft = w C ft + w 2 C ft,2 + w 3 C ft, correction = ($ $5,000 + $,000)/(50 ft + 90 ft + 65 ft) = $70.73 per ft Second column, in the table in the solution, "+55-5 = = +5". Rest of solution is correct correction First column, in the Solution to Example 86.28, calculation of E(EUAC(A)): "...+ ($600,000)( )...+ ($600,000)( )". Rest of solution is correct correction Second column, near the top: "Use App. 22.C" should be "Use App. 22.B." 25-4 correction Second column, near the top: "are found in App. 22.Care found in App. 22.B" correction Second column, Solution of Ex. 25.2: "From App. 22.CFrom App. 22.B". 25- correction Second column, in TWO places: "Appendix 22.C" should be "Appendix 22.B", and "App. 22.C" should be "App. 22.B". 4/5

Second column, bottom: In part (c) of the solution correction 7-39 correction of Ex. 2.2, "S max = 8.87 cms max = 8.67 cm". First column, in the third line of the example: For the steel, "E = 2 x 0 9 PaE = 2 x 0 Pa". The correct value was used in the subsequent calculations correction Second column, near top. "0.35 lbf/ft 3 " should be "0.35 lbm/ft 3." The correct units are picked up in the subsequent step correction Second column, second line after Eq. 8.36: "...characteristicsof...characteristics of..." correction Eq. 5.36: correction Second column, in Eq. 7.3, the exponent on C in the denominator should be.85 not.85.
