The designs of fin drains vary dependant upon the flow capacity that is required. The geosynthetic has the capacity to transport a certain flow (i. e. it has a certain transmissivity) – see diagram A, above. Where this is insufficient a pipe can be added to increase the outflow capacity, diagrams B and C. The dimension of the pipe varies depending on the additional capacity that is required.

B.5.3 Core Designs for Fin Drains

2

Core designs other than those shown here are also used. The purpose of the core is to support the geotextile membrane without hindering the flow of water within the thickness of the geosynthetic.

The figure, above, shows a plan view of a geocomposite highway edge drain, comprising a core (3/4/5) between two geotextile sheets (1/2). Some cores have one permeable side (e. g. geotextile layer 1) and one impermeable side (e. g. in place of geotextile layer 2) where water is to be collected from one side of the fin drain and not to be drained from the other, but these are seldom employed in highway construction except where an impermeable face (e. g. part of a retaining wall) abuts the pavement. The core may be formed in a number of ways, some of which are illustrated here: 3=plastic plates with pillars to separate faces; 4=concertina waffle structure, 5=dimpled plastic sheet. Nets/grids and stiff, entangled polymeric strands may also be used to provide a permeable core.

Housekeeping

Housekeeping is something we all grow up with. Some learn it better than others. On the job site, we all must practice good housekeeping because it affects safety and productivity. There are three main housekeeping issues: job site scraps, personnel debris, and tool organization.

Job site scraps are the cut-off ends of pieces of wood, lumber torn down that will not be used again, wrapping from lumber, empty nail boxes, and numerous other materials brought onto the job site that will not be used. You don’t always want to take the time to attend to this debris at the moment it is made, but you do need to make sure that it is not left in a location that would pose a safety problem,

such as in a walkway or at the bottom of a ladder. As you create the scraps, throw them in a scrap pile or at least in the direction of a scrap pile. Many cut-off pieces of lumber can be used for blocking and should be thrown in the direction of where they will be mass-cut later.

Whenever you have lumber with nails sticking out, pull the nails out if you are going to use the lumber again, or bend them if the lumber will be thrown away. It is easy to forget this, so be sure to attend to the nails while you are working with them and they are on your mind.

Personnel debris is the garbage individuals create personally, like lunch scraps and soda bottles. It makes it easier on your crew if you provide some sort of container near the lunch spot. You will be lucky if you don’t have to keep reminding your crew that they are responsible for their own personal garbage.

Tool organization can save you time and a lot of aggravation. With tools that are in common use by the crew, it is important to return the tool to where it belongs. If tools are not stored in a location where other framers can expect them to be, a lot of time will be wasted looking for them. When rolling out your electric cords and air hoses, keep them organized. If you have to roll out in a walkway, try to stay to one side or the other. If you have to move your hose or cord, and it is rolled out underneath someone else’s cord or hose, be careful that when you move yours, you don’t drag theirs (and possibly their tools) along with you.

Housekeeping is sometimes difficult to organize, but getting it right can be a big asset for safety and productivity.

The VE Task Force presents the awards in the categories of (1) process improve­ment, (2) project delivery, and (3) preconstruction engineering (design, utilities, right – of-way, and construction). The awards for 2007 for the most value added proposals are summarized below.

Category: Improved Process

Agency: California Department of Transportation (Caltrans)

Project: Antioch and Dumbarton bridges Geotechnical Investigation Requirements to

Develop Retrofit Strategy

Citation:

This unique study analyzed the geotechnical investigation requirements necessary to develop the strategy that leads to retrofit recommendations for the Antioch and Dumbarton bridges. Caltrans will use this study to develop an appropriate retrofit strategy for each bridge. The baseline scope placed heavy emphasis on conducting new explorations and associated labora­tory testing to obtain more dependable data (baseline estimate of $12,100,000). The value analysis (VA) team concluded that the objectives of the investigation could be achieved with fewer new exploratory borings drilled to somewhat shallower depths. Other recommended alternatives also improved the project and lowered cost, with implemented savings of $2,350,000 or 19 percent. All recommended alternatives were accepted and implemented.

Category: Project Delivery

Agency: Minnesota Department of Transportation

Project: TH 212 Design-Build Project, State Project No. SP 1017 12

Citation:

The TH 212 Design-Build Project is a $238 million construction project consisting of 11.75 miles of new four-lane divided highway realignment, 7 interchanges, 28 bridges, and numerous retaining and noise walls. The VE proposal is to eliminate a bridge and provide for the realignment of a crossing road to intersect where the main line creek crossing occurs. This combined crossing concentrates impacts and construction activities in one location. This change minimizes environmental impacts to the creek, the big woods remnant vegetation, and the flood plains, and reduces slope stability issues. The VE impacts include savings in project costs, and reduced construction impacts and future maintenance activities. The new design eliminates an insufficient horizontal curve design exception, improves sight distance at an intersection, reduces the total acreage disturbed, and creates less impervious area.

Category: Preconstruction Engineering < $25 Million

Agency: Florida Department of Transportation Project: Protection of US 98 on Okaloosa Island Citation:

US 98 on Okaloosa Island has been damaged by storm surges from at least five tropical events in the last ten years, resulting in more than $16 million in repair work. The purpose of this project was to provide additional protective features to reduce the potential for future damage from similar storm events. The District wanted the additional protection in place prior to the next storm season, which required the project to be designed and constructed in less than one year. The recommendation developed by the team and accepted by management reduced the cost of the $20.6 million project by $8.3 million, or 40 percent, and also reduced the construction time by 50 percent. A key product innovation from the VE team was the rec­ommendation to use Teflon sheet piling to replace conventional concrete sheet piling.

Category: Preconstruction Engineering $25-$75 Million

Agency: Transport Canada, Ontario Ministry of Transportation, and the City of Windsor Project: Let’s Get Windsor Essex Moving, Walker Road and Howard Avenue Grade Separations VE and Risk Study Citation:

Security measures at the U. S. border have caused significant traffic problems in the City of Windsor. One of the problems was the need to x-ray rail cars entering the United States, which reduced train speed and increased traffic delays at major arterial road-rail crossings in the city. An immediate and concerted effort was put into place to grade separate two major urban road crossings. The original project cost estimates increased dramatically due to the rushed design, limited property, business and industrial activities, traffic operations, and a myriad of major utility issues. A VE study and Cost Risk analysis improved commu­nication with the city, Transport Canada, Ontario Ministry of Transportation, and designers; saved $2 million; identified risks; brought certainty to the cost estimates; and clarified project scope.

Category: Preconstruction Engineering >$75 Million

Agency: New Jersey Department of Transportation Project: Route 52 Causeway Replacement Contract A Citation:

The Route 52 Causeway Replacement Contract A project involves the replacement of 1.2 miles of existing Route 52 Causeway, including 2 structures displaying structural, geometric, and safety deficiencies. Bids far exceeded original estimates. The VE repack­aging of Contract A converted Rainbow Island from bridge structure to roadway by grade touchdown utilizing fill. Additionally, the VE changes introduced conventional fixed bridges as an alternate design to high-level bascule bridges. VE design and bridge changes reflected through this repackaging effort resulted in a low bid of $141,350,400, with a net savings of $88,636,000, and improved constructibility by acquiring environ­mental permits that allowed timely construction without seasonal delays.

Category: Preconstruction Engineering >$75 Million—Honorable Mention

Agency: Central Puget Sound Regional Transit Authority (Sound Transit)

Project: 755 Segment of Sound Transit Central Link Light Rail Project Citation:

The 755 Segment of Sound Transit Central Link Light Rail Project extends approximately 5 miles, from the Boeing Access Road to a station at Southcenter Boulevard. This LRT guideway is mostly elevated and parallels or crosses over Washington State Department of Transportation (WSDOT) freeways along much of its route. The design team undertook an intensive value engineering study of the 30 percent preliminary design at the beginning of the final design assignment. The VE study identified significant configuration changes that were forecast to save $23 million and approximately 8 months of construction duration. Sound Transit evaluated and accepted the recommendations for incorporation into the final design. The potential savings and other benefits identified in the value engineering work were validated by the bids received and continue to be realized during construction of the $234 million project.

[1] The alignment should be as directional as possible while still consistent with topo­graphy and the preservation of developed properties and community values.

• Maximum allowable curvature should be avoided whenever possible.

• Consistent alignment should be sought.

• Curves should be long enough to avoid the appearance of a kink.

[2] Rounding should be 4 ft where the foreslope begins beyond the clear zone or where guardrail is installed and foreslope is steeper than 6:1. No rounding is required when the foreslope is 6:1 or flatter.

Note: No attempt has been made to include every bridge type in the above tabulation.

[8] Entrance and exit. The deceleration and acceleration lanes adjacent to the main roadway can be lighted so that a motorist can safely transition into and out of the rest area. When the main roadway is not lighted, an average illumination of 0.6 fc (6 lx) should be maintained on the deceleration with three to five luminaires along the speed change lanes. On the exit gore and acceleration lane, 0.6 fc (6 lx) is rec­ommended to a point where the motorist can merge onto the main roadway. If the main route is lighted, the entrance and exit lanes should be lighted to a level equal to that of the main route.

• Interior roadways. These are the roads for the entrance gore to the parking areas and from the parking areas to the exit gore. The recommended illumination is 0.6 fc (6 lx) with a uniformity of 3:1 to 4:1.

The design of lighting for rest areas requires consideration of both vehicle and pedes­trian needs. Properly designed rest area lighting will enhance the architectural and landscape features of the facility, promote safety by easing the task of policing, and contribute to the rest and relaxation of motorists by adequately lighting the driving, parking, and walking areas. In areas with landscaping or in natural settings, the lighting designer often attempts to make the light poles less noticeable by causing them to blend with the environment. One cost-effective method uses colored fiberglass rein­forced poles that blend with the surrounding environment. These poles are usually of the direct burial type that can be installed with or without breakaway devices.

The lighting system designer should be mindful of motorists on the travelway by not allowing glare or spill light from the rest area luminaires to adversely affect their vision. The motorist on the main roadway should be able to see any vehicles leaving the rest area as well as traffic along the main route. The lighting concerns for rest areas can be divided into several distinct areas:

[10] Obtain soil parameters for both backfill and foundation. Usually the cohesion­less backfill is slightly larger than Rankine zone. This enables the designer to use the properties of backfill material to estimate earth loads; otherwise the properties of retained material must be used.

[11] Determine the appropriate design cases and load combinations. Load types are designated as follows: D, dead load; E, earth load; SC, surcharge; RI, rail impact; and W, wind load. Typical load combinations are as follows: sloped or leveled fill without rail, D + E; leveled fill without rail, D + E + SC; leveled fill with rail, D + E + RI; and leveled fill with rail and fence, D + E + SC + W.

STRETCHING CARPET

Once the carpet seams have cooled, stretch and attach the carpet to the tackless strips around the perimeter of the room, using the knee-kicker, power stretcher, and stair tool. Actually, if you must join carpet seams, you already will have used the knee-kicker to draw the carpet edges taut so the glued seam will be a straight.

Typically, stretching begins in a corner, using a knee-kicker. Place the knee-kicker about 1 in. from the wall and rap the cushion of the tool

Подпись: 9. After stretching a carpet, use an edge trimmer to cut off the excess around the perimeter of the room. Then use a stair tool to tuck carpet edges behind tackless strips or under baseboards. That’s pretty much it. Once the second corner is attached, alternate using the knee-kicker and the power stretcher, somewhat as shown in "A Carpet-Stretching Sequence,” below. There’s no one always-best sequence. Keep an eye on what the carpet is doing, and use the tool that seems right. Seen from above, your carpet-stretching movements would resemble something between a tennis match and icing a cake. Back and forth, fine tuning as you go.

TRIMMING CARPET

Подпись:Once the carpet is secured to the tackless strips and the transition pieces in the doorways, use an edge trimmer to remove the excess; trimmers also tuck the edge of the carpet to a degree. After trimming the edge, go around the perimeter with a hammer and a stair tool, tamping the carpet between the tackless strips and the wall, or under the baseboard trim. It’s important that the trim­mer’s blade be sharp, so change razors whenever the tool drags, rather than cuts.

image1046Подпись: To stretch carpeting, alternate using a knee-kicker and a power stretcher. Typically, use a knee-kicker to secure a short section of carpet to tackless strips nearby, before using a power stretcher to stretch carpet across the room and secure it to strips along an opposite wall.

quickly with your knee. When done properly, this maneuver carries the carpet forward and onto the points of the tackless strips. Then use the stair tool to pack the carpet into the small gap between the strips and the wall, also to securely lodge the carpet on the tack point. Knee-kicking takes a little practice. But, as more of the carpet is attached, and there is some tension on it, the task becomes easier. As you work along an edge of the carpet, rest your hand on the section just attached. The extra weight will prevent the section from being dislodged by successive knee-kicks.

After securing a corner 2 ft. to 3 ft along each wall, assemble the power stretcher to stretch the carpet to an adjacent corner across the room. To do this, place the tail end of the power stretcher on a 2×4 block resting along a baseboard of the corner you just attached; the 2×4 prevents the tail end of the stretcher from damaging the finish wall. Unlike the knee-kicker, which rebounds, the stretcher has a lever that extends the tool and holds it there until the lever is released. Before you engage the stretcher’s lever, place the stretcher head 5 in. or 6 in. from the wall you’re pushing the carpet toward. Once you push down on the lever, the stretcher head should move the carpet about 2 in. forward, leaving you plenty of room to use the stair tool and secure the carpet to the tackless strip.

METHODS OF CALCULATION

The concepts of annualized cost and present worth are employed in LCC. Using the annual­ized cost method, all costs incurred are converted to equivalent annual costs using a base­line and a specified life span. For example, initial costs would be amortized over the life cycle and include principal and interest (similar to home mortgage payments). Replacement costs or rehabilitation costs at various points during the life cycle would also be converted to equivalent annual costs (sinking fund). The following steps can be employed:

1. Annualized initial cost. Tabulate all initial (acquisition) costs. These include the base cost of each of the alternative systems and any other initial cost. Total these ini­tial expenditures to arrive at the total initial cost (IC). Next, amortize the initial costs (IC) by determining the annual payment necessary to pay off a loan equaling the total initial cost. Using a capital recovery table or the following equation, find the periodic payment (PP) necessary to pay off $1.00 at a discount rate of r over a period of n years. Each total initial cost is multiplied by this factor to determine the annualized cost for this element.

r

1 – (1 + r)-n

2. Annual recurring cost. The next step is to tabulate, for each alternative, the average annually recurring costs for operations, maintenance, and other known factors.

3. Annualized nonrecurring cost. Next, determine the replacement or rehabilitation costs for all major items, for each alternative, at appropriate times during the life span. Also determine the salvage value at the end of the life span. Each of the replacement costs is then discounted from the point in time where the funds are to be expended. Multiply each cost by the present worth factor (PW) from a table or calculated by the equation

PW = (1 + r)-n

Then, the present worth of these replacement and salvage costs is reduced to a uniform series of payments by applying the same capital recovery periodic payment factor (PP) used in step 1. Salvage or residual values are treated similarly except that the resulting costs are negative.

4. Total annual cost. Finally, sum the annualized initial cost, annual recurring cost, and annualized nonrecurring cost for each alternative to determine total annual costs. These costs represent a uniform baseline of comparison for the alternatives over a projected life span at a selected interest rate. The annual differences are then deter­mined and used for recommendations.

5. Present worth of annual difference. To determine the real value of an annual cost difference, calculate its present worth. Multiply each cost by the present worth annu­ity factor (PWA), which shows how much $1.00 paid out periodically is worth today in real dollars. The factor may be obtained from a table or calculated by the equation

1 – (1 + r)-n

r

Thus, one may then compare the present worth of each alternative to assess the bene fit derived.

6. Effect of inflation. The effect of inflation should be considered in the calculations when determining annual recurring cost, replacement cost, and salvage value, If infla­tion is constant at a rate i, costs at a future date of y years can be found by multiplying the cost by an inflation factor (IF) given by the equation

IF = (1 + i) у

Thus, the calculations can be made using costs that allow for inflation. Using this procedure, different costs can be adjusted for different levels of inflation, if there is information to support such choices. More complex methods for handling inflation are also available.

If the items being compared do not involve different annual costs, it is more direct to make the present worth calculation directly. Future nonrecurring costs over the project design life can be reduced to their present worth value by multiplying by the PW factor given above, PW = (1 + r)“n. These are added to the initial costs to determine total pre­sent worth of each system. The present worth of alternative systems can then be compared.

10.10.1 Example of Calculations

A simple example to illustrate the above calculation method is presented in Table 10.4. In this example, inflation is handled by using a net discount rate equal to the nominal discount rate (assumed as 10 percent) minus the rate of inflation (assumed as 5 percent). Two pipe materials are being considered for a drainage application where the project design life is 50 years. Initial costs associated with pipe A are $150,000, and those associated with pipe B are $180,000. Pipe A will require a $37,400 rehabilitation at the end of 40 years, and pipe B a $25,000 rehabilitation at the end of 45 years. Pipe A will have no salvage value, and pipe B will have a salvage value of $30,000. For illustrative purposes, each is assumed to have an annual maintenance cost of $1000. Calculations in part A show that for the assumed conditions, pipe A will have the lower annualized cost and the present worth of the difference in annual cost is $24,900. Calculations in part B show the same difference in present worth, since the annual recurring costs are the same in this example. (For an example of LCC in pavements, see Art. 3.11.)

Life cycle costing is a technique to assess the total cost consequences between alternatives. The potential to optimize value through LCC is only as good as the alternatives being considered. It should be used in proper sequence as part of the VE effort.

CATEGORIES OF COSTS

Costs that must be considered depend to some extent upon the system or project analyzed,

but can generally be categorized as follows:

1. Initial costs

a. Item costs. These are costs to produce or construct the item.

b. Development costs. These are costs associated with conducting the value study, testing, building a prototype, designing, and constructing models.

c. Implementation costs. These are costs expected to occur after approval of the ideas, such as redesign, tooling, inspection, testing, contract administration, train­ing, and documentation.

d. Miscellaneous costs. These costs depend on the item and include costs for owner-furnished equipment, financing, licenses and fees, and other one-time expenditures.

2. Annual recurring costs

a. Operation costs. These costs include estimated annual expenditures associated with the item such as for utilities, fuel, custodial care, insurance, taxes and other fees, and labor.

b. Maintenance costs. These costs include annual expenditures for scheduled upkeep and preventive maintenance to keep an item in operable condition.

c. Other recurring costs. These include costs for annual use of equipment associated with an item as well as annual support costs for management overhead.

3. Nonrecurring costs

a. Repair and replacement costs. These are costs estimated on the basis of pre­dicted failure and replacement of major system components, predicted alter­ation costs for categories of space related to the frequency of moves, and capital improvements predicted necessary to bring systems up to current stan­dards at given points in time. Each estimated cost is for a specific year in the future.

b. Salvage. Salvage value is often referred to as residual value. Salvage value is not really a cost, in that this factor is entered as a negative amount in the LCC calculation to reduce the LCC amount. Salvage value represents the remaining market value or use value of an item at the end of the selected LCC life span.

ACCORDING TO A SURVEY in Builder

Magazine, Habitat for Humanity is the

15th largest house builder in the U. S.

a Since its founding in 1976, Habitat for Humanity has built or rehabilitated more than 40,000 houses throughout the U. S.

^ More than 350 Habitat houses have been built by all-women crews.

a According to The Chronicle of Philan­thropy Habitat for Humanity is the 23rd largest nonprofit organization in the U. S.

a The average Habitat house built in the U. S. costs just over $48,000, encom­passes 1,100 sq. ft. of living space, is held together with 20,000 nails, contains 650 pieces of lumber, and is finished with 40 gal. of paint.

a Habitat for Humanity has 1,621 affil­iates in the U. S. (including Guam and Puerto Rico) and 497 international affiliates in 83 countries.

Smoke detectors and fire extinguishers save lives

Smoke detectors can and often do save lives, especially when a fire breaks out while you are sleeping. Most codes require that smoke detectors be installed in every bedroom and hallway. Some detectors are designed to be wired into your electrical system (with battery backup in case of power outages), while others work on battery power alone. You need to know the location of these units so you can check them every three to four months by pressing the test button that’s clearly visible

on each detector. If the unit is operating prop­erly, it will emit a high-pitched sound.

A while back, a friend was visiting and left a small towel on top of the stove not realizing that one of the burners was on. In just a minute or two, the towel was ablaze. A handy fire extinguisher quickly put an end to what could have been a major disaster. Fire extin­guishers are inexpensive and have been put in all the Habitat houses I have worked on. Install one in the kitchen where it is easily vis­ible and accessible so that anyone can locate it quickly. Drive the mounting screws into a stud so the fire extinguisher is securely attached.

[1] Clip the first nail by bending a second nail over it. Hammer the clip until both nails are fully em­bedded in the wood.

[2] Prepare for Truss Arrival and Installation

[3] Cover the inside and outside corners. This is an optional step, but one that I routinely take to provide extra protection in these crit­ical areas, especially if the siding will be installed directly over the studs. Fold a 2-ft.- wide wall-high length of wrap in half and staple it vertically over the outside corners and into the inside corners.

[4] Wrap the house from corner to corner.

If a 12-ft. roll is too tall for the house you’re working on, cut the roll roughly to length

[2] For a recent synthesis of the birth of agriculture and the Neolithic revolution, see the book of the pre­historian and archaeologist Jacques Cauvin, Naissance des divinites, naissance de l’agriculture, la revo­lution des symbols au Neolithique, revised in 1996.

[3] Some have proposed that population pressure explains the exodus which clearly accompanied the Neolithic spread (each generation seems to have migrated 20 kilometers or so). But according to Jacques Cauvin, this explanation is inadequate; he sees in addition a profound change of mentality, responding to the call of the “new frontier”.

[4] According to Geyer and Besanfon (1997), the Euphrates was in a sedimentation phase until the VIIth millennium BC, having a braided morphology which favored early seasonal, non-irrigated agriculture. From the VIth millennium BC, the river entered a new phase of erosion of its bed into its own alluvia. The terraces that were formed as a consequence, protected from flooding a dozen or so meters above the riverbed, became favorable to permanent settlements. Irrigation then became necessary.

[5] Cauvin (1969), p. 239. Evidence of such drainage may also have been observed at Bouqras.

[6] See for example Huot (1994), describing the explorations performed by the American archaeologist John Oates in 1967-68.

[31] The Bahrain and Oman archaeological sites of the 3d millennium BC have been partially explored (Cleziou, 1987). It has been established that the copper used in lower Mesopotamia in this period came from the mines of the mountains of Oman. At the eastern extremity of the peninsula have been found remnants of tar used to waterproof seagoing vessels, as well as objects characteristic of the Indus civi­lization. The tasty dates of Dilmun are celebrated in Sumerian texts. Dilmun had numerous artesian wells and luxuriant palm groves.

This dam, built with limestone blocks cemented with a chalk – based mortar, could be a Hellenistic or Roman reconstruction, given the proximity of Doura Europos, of a structure from Mari or even from an earlier time, for there is a very ancient inhabited site here.

[62] Akkadian texts engraved in cuneiform writing on tablets of baked clay; this evidence dates from the reign of Zimri-Lim, one of the Amorite successors of Yahdun-Lim, who reigned 14 years and was the last king of Mari.

[67] Geyer (1990).

[68] Jean-Claude Margueron is a strong proponent of the hypothesis of an ancient navigation canal (see his various publications). Prior to the era of Zimri Lim, from which the texts cited herein are drawn, a message sent by a king of upper Mesopotamia, whose domains include Mari and its region, is of inter­est. The message asks that precious wood coming from Qatna in Syria, coming down the Euphhrates to Suprum, “be brought upstream by boat to Saggaratum, from there (again by boat) to Qattunan (further up the Khabur). From there, the wood can be transported on carts…” (Durand, letter No. 187). J. C. Margueron brought this letter to my attention. The importance that it gives to Suprum as a transfer port, and to Saggaratum as a stopover, is quite consistent with the notion of a grand navigation canal.

[79] This title could be contested by the Homs dam in Syria that is attributed by some to the Egyptians, but that probably dates from the Roman occupation. We come back to this in Chapter 7.

[87] This account, called the “stela of famine”, relates the difficult years that were said to have occurred under the reign of Djoser, 2nd Pharaoh of the 3rd Dynasty (about 2600 BC).

[105] 10 cm per century, according to Butzer (1998). The normal level of the Nile at the latitude of Fayoum, today at an elevation of +24 m, was probably about +20 m at the beginning of the IInd millen­nium BC.

[106] These data are from the geological studies synthesized and analyzed by Butzer (1997). The eleva­tion of -2 m reached around 2000 BC is derived from the geological work of Gardener and Caton – Thomson (1929), cited by Garbrecht (1996). Annual evaporation in this region is estimated at 1.7 m; the lake level could therefore fall some 20 m in a dozen years.

[117] This zone is unoccupied in the Middle and New Empires, as attested to by Jean Yoyotte (see his note 266 in Strabo’s Travels in Egypt (Le voyage en Egypt); see also Carol Redmount, 1995). This author raises the possibility of a canal to Tell el-Rebatah built in the New Empire; the canal would be more to the north, and more modest, than the actual canal of the two seas. The text of Linant de Bellfonds nice­ly describes the remains of two distinct canals to the west of this site, one on the north flank of the wadi Tumilat valley, the other on its south flank.

[165] Our principal general sources concerning the Library and Museum of Alexandria are the works of Geoffrey Lloyd (1973), Luciano Canfora (1986) and the article of Anita Measson (1994).

[166] Sometimes acquisition by force: on transiting boats stories were told of books that were confiscated, only copies to be returned to the owners.

[167] But many fewer books: only the shortest of books could be contained in a single roll. This estimate is discussed in detail by Luciano Canfora (1986).

[168] We recall that Greek science had established that the earth was round in approximately the 6th centu­ry BC. The circumference obtained by Eratosthene was 250,000 stadia or 39,690 km, taking the stadi­um to be 157.5 m, compared to the modern accepted Figure of 40,009 km (Lloyd, 1973)

[169] Vitruvius, X, 7, 4.

[170] These hanging gardens are described by Strabo (Geography, XVI, 1, 5), but not by Herodotus who wrote during the period of the Achaemenid Persians. Thus it seems probable that they were not devel­oped until the Hellenistic period.

[171] A passage in the work of Philon may suggest hydraulic force to turn a lifting waterwheel (noria). But we know this work only through an Arabic transcription, and there is some doubt as to the authenticity of the passage (it could be an addition from the Islamic era, during which the use of hydraulic energy is widespread). We share this doubt. There is no evidence of the use of hydraulic force before the 1st cen­tury BC (see further on), and even during the era of Strabo’s voyage in Egypt (25 BC), there are no hydraulic machines on the Nile. His account is perfectly clear on this point (we cite an extract further on).

[172] Heron, “Pneumatics”, I, 16, cit. after Lloyd (1973).

[173] Note the dedication of Archimede’s treatise “The Method”: “Archimedes to Eratosthene, prosperi­ty! I earlier sent you certain theorems that I had discovered, giving you only the statements and invit­ing you to discover the proofs…” (Vol. III of Works of Archimedes, Edited in French by Les Belles Lettres, 1971, adapted).

[176] Here, in summary, is how this proposition is deduced from the initial postulate: if this were not the case for a liquid at rest, two points inside the liquid, situated on a sphere centered at the center of the earth would be compressed by different water heights above them, thus “the part that is the least compressed is displaced from its position by a more compressed part; it follows that the liquid cannot remain at rest.”

[177] The Roman engineer Vitruvius writes later, in book VIII of his treatise On Architecture (V, 3): “Perhaps those who have read the works of Archimedes will say that one cannot establish an exact level using water, since Archimedes teaches that a water surface is not a level plane, but a sphere having as its center the precise center of the terrestrial globe. But whether the water surface is planar or spheri­cal, if a horizontal straightedge is laid upon the surface of water in a gutter, then this straightedge, at its left and right extremities, necessarily is at the same distance above the water surface; if, on the other hand, the straightedge is laid on a slope, one end of it will be above the water while the other touches it.”

[178] Gunther Garbrecht (1983) gives an excellent overview. See also Trevor Hodge (1995).

[179] According to Gunther Garbrecht, many of these elements were secretly sold to collectors, but the three pipelines are quite visible at certain locations.

[180] 22 cm according to Gunther Garbrecht (1979), only 17.5 cm according to Trevor Hodge (1995). These dimensions are suppositional, no element of this conduit having been recovered. The exterior diameter of 30 cm is, on the other hand, well established on the basis of the diameter of holes in the blocks that supported the conduit.

[185] In effect, Claude Orrieux (1983) situated the “domain of the 10,000 aroures” between the altitudes +20 m and -10 m. Other studies have situated this elevation at -2 m (Garbrecht, 1996).

[186] One can consider that Apollonius served the king in an intermediate function, between that of a Finance Minister and Prime Minister, according to our references. He very closely followed the agri­cultural performance, this being the principal source of fiscal revenue.

[221] This is of course not the Hellenistic aqueduct of Mandradag (Chapter 5), but rather the Roman aque­duct of the Kaikos valley. It comes from the east; even though its elevation is high enough to supply only the lower quarters of the city, it transports a much larger quantity of water than the Hellenistic aque­duct.

[222] This indication is somewhat uncertain (5 cm/km?) It does not correspond to actual slopes in the aqueducts.

[233] The reader can consult the article of Marcel Bailhache (1979).

[234] Sources: Grenier (1960), Bailhache (1979), Burdy (1979, 1996), Jeancolas (1983), Pelletier (1983), Fabre et al (1992), Andrieu (1997), Andrieu and Cazal (1997), Ardhuin (1997), Jaccotey (1997), Lefebvre (1997), Provist and Lepretre (1997), Rigal (1997).

[235] One reference study, unfortunately disappeared, is that of Germain de Montauzan (1909). Here we have based our discussions primarily on the study of Louis Jeancolas (1977, published in 1983), on the synthesis of Jean Burdy (1979), and on the monograph of Jean Burdy on the Gier aqueduct.

[236] This is the “traditional” dating estimated by Germain de Montauzan; Jeancolas, based on the remains of a tomb that is said to have preceded the aqueduct, estimated that the aqueduct could date from the second part of the 2nd century AD. In this case, the aqueduct would be the most recent of the four.

[237] the water velocity is greater than that of the wavespeed. For more detail, see Chanson (2000).

[238] This is the hypothesis of Louis Jeancolas, from his observation of a piling of the Craponne aqueduct that is particularly reinforced, suggesting that it could have supported the structure at the junction of two aqueducts.

[239] ”Chagnon Stone”, discovered in 1887, visible under the playground of the Chagnon school. A sec­ond inscription, apparently identical, was discovered in 1996 along the main path of the aqueduct, but further downstream (Burdy, 1996).

[240] Difference in water level between the head tank and exit basin.

[241] These data have an unexplained anomaly. An elementary hydraulic calculation shows that the ratio of the head losses must be equal to the ratio of the lengths of the two parts of the double siphon, if the pipes are identical and of the same number.

[242] Our principal sources here are the article of Victor Lassalle (1979), conservator of the museum of Nimes, and the work of Guilhem Fabre, Jean-Luc Fiches, Philippe Leveau, and Jean-Louis Paillet (1992) who coordinated, from 1984 to 1990, a program of research on the aqueduct of Nimes and the Pont du Gard.

[243] This new date is that established by Fabre, Fiches, Leveau and Paillet (1992). Earlier, the aqueduct had been attributed to Agrippa, the son in law of Augustus, also presumed father of the first aqueduct of Lyon (around 19 BC). The Brevenne aqueduct is also attributed to the era of Claudius.

[244] The ancient writings refer to an elevation of 76 m for the tapping of the Eure fountain. We have adopted here the more recent estimate of Fabre et al. (1992), namely 72 m.

[245] It is probably to reduce the height of the Pont du Gard that the aqueduct’s slope is steeper upstream than downstream of it.

[246] It is about 150 km long; see Figure 6.32 below (Balty, 1987).

[260] The first description comes from the discoverer of the site, Fernand Benoit, in 1935. We have used here the results of the more recent study of Sellin (1979) for the flour mill itself, and of Leveau (1995) for its water supply.

[261] The first studies of the site supposed that this distribution system was a triangular reservoir. Sellin showed that it was more likely two canals, laid out in the form of a “V”, supported on walls that are still visible today, conveying water into the headraces. We have adopted this hypothesis in Figure 6.24.

[294] This was a frequent argument in Antiquity. It was used at the time of the Pharaoh Necho in the con­text of the canal of two seas.

[295] For example, in the aqueduct of Nimes with a discharge of 66,000 m3/day, if one takes as a simpli­fication a constant slope of 0.38 m/km upstream of the Pont du Gard, and a smaller slope of 0.18 m/km between the bridge and the city of Nimes, one finds that the water depth should be approximately 0.96 m along the first segment and 1.3 m along the second one, these values representing the useful depth of the canal (calculations done with a wall roughness of 5 mm and a canal width of 1.22 m).

[296] After Viollet, Chabard, Laurence, and Esposito (1998); the calculated velocities and discharges cor­respond to a slope of 1.3 m/km and a wall roughness of mean height 3 mm.

[365] In Antiquity, China is known, in the West, by two principle names: Seres, derived from the Chinese Si signifying silk, and Sina, that is thought to have come from the name of the Qin Dynasty. The first name arrived in the Occident through the intermediary of the Greek world; the second seems to have come by the route of the Indies (Needham, 1978).

[372] This does not mean there was nothing further to the south. Archaeology has indeed shown the exis­tence of a culture of rice in the basin of the Yangtze (the Blue river) from 6000 BC. But it is clearly in the north that organized civilization, destined to spread, was established (see for example Debaine – Francfort, 1998).

[384] The slope of the Yellow River is about 1.1 m/km along its upper course (3,472 km); 0.74 m/km on its middle course (1,200 km); and only 0.11 m/km along the 786 km of its lower course – after Lian Ruiju, Zheng Zhaojin, Hu Jialin (1987).

[385] The main bed of the river, the narrow channel in which the river flows during low-water periods, is formed in the bed’s sediment, and therefore is not significantly super-elevated compared to the plain. The overflow bed, on the other hand, is much wider and is occupied during periods of high water; and can be more than ten meters above the level of the surrounding plain.

[389] The hypothesis that Ye is near Handan is taken from the work of Henri Maspero (p. 145) and Jacques Gernet (p. 65). This localization is consistent with the fact that Ye was irrigated by Ximen Bao, using water taken from the Jian, which is precisely what Sima Qian said. It is curious, however, that this city, still active as the center of the cult of the river around 400 BC, was not located on the course of the river itself in this period, since the course had changed in 602 BC. Marcel Granet (Dances and legends, p. 474) situates Ye more to the south, near the place where the ancient course of the Yellow River arrives on the plain and turns toward the north.

[403] According to Needham, Li mentions the idea of separation. It is therefore possible that the name of the river – the Li – comes from the structure mentioned here, separating the discharge from the Xiang. One could say the same of the Li escarpment, at Dujiangyan: it is separated from the hill by the notch through which the canal passes.

[466] The rapid growth of references to mills in deeds from Picardy in the 11th and 12th centuries may not be significant, for the number of deeds being rediscovered and archived is, in itself, growing rapidly (see Gies and Gies, 1994; Derville, 1994).
