Conflicts and Deviations The selection of material and equipment, and the design, construction, maintenance, and repair of equipment and facilities covered by this Standard shall comply with the latest edition of the references listed below, unless otherwise noted. Company Representative: Saudi Aramco's authorized representative with overall authority and responsibility for the project. Contract or Contract Documents: Any and all documents, including design drawings, which Saudi Aramco has transmitted or otherwise communicated, either by incorporation or by reference, and made part of the legal contract or purchase order agreement between Saudi Aramco and MAKANA.

Contractor: The party responsible for performing excavation and backfill, including work executed through the use of sub-contractors. Dune Sand: is wind-deposited sand consisting of relatively single-sized particles generally passing the No. Fill Material: see section 6. Hard Rock: see Rock Excavation, section 7. Marl: is a wide variety of calcareous soil materials found in Saudi Arabia which may vary from clay to gravel sizes and often include cobble and boulder sized pieces. Rocks: have various hardness and engineering properties.

See section 7. Sabkha: is a saline generally coastal deposit generally consisting of saturated, loose silty sand and possibly clay. MAKANA shall institute a quality control program that will verify or ensure that the work performed under the contract meets the requirements of this Standard and the design drawings as per Inspection document "Schedule Q". Should it be later found that some work has been completed not in compliance with this Standard, it shall remain MAKANA's responsibility to repair or reconstruct deficient work until specifications are met at no cost to Saudi Aramco.

Field test reports shall include density and moisture content test logs indicating location by coordinates and elevation. Reports shall be submitted on the following:. Sources and test results of all borrow materials and compaction water used for fill prior to beginning fill operations. All excavations, including shoring and sheeting materials and systems, shall meet the minimum requirements established by the Saudi Aramco Safety Management Guide If an Excavation Plan is required and shoring is used, the Plan is to: a Describe the materials and shoring system to be used.

If dewatering of an excavation is required, MAKANA shall submit proposed methods and details to the Saudi Aramco Company Representative for review, before beginning dewatering and excavation. Known contaminated soils within the construction limits shall be managed in accordance with a contaminated soil management plan provided by Saudi Aramco prior to the start of excavation. If unexpected. MAKANA shall ensure that all areas shall be maintained using temporary erosion and sediment control measures during construction or until relieved by the Saudi Aramco Company Representative or until permanent measures are completed and functioning in a satisfactory manner.

The adequacy of the dust control shall be determined by the Saudi Aramco Company Representative. Ponding of water on placed fill or within excavations shall not be allowed.

Excavations for foundations and other underground installations shall not be used as temporary drainage ditches. All excavation and trenching shall be done in accordance with all Saudi Aramco safety requirements including, but not limited to, the Saudi Aramco Saudi Aramco Safety Management Guide All necessary permits must be obtained from Saudi Aramco prior to performing any earthwork.

One or more of the following permits are required as applicable:. When any excavation or trench reaches a depth of 1. Excavations are not allowed to intersect a 45 degree plane extending downward from the bottom edge of existing foundations unless an engineered support system is in place prior to the start of work or the excavation is in stable rock. Fill or backfill of the excavation must meet the compaction requirements in Paragraph 6. Whenever Saudi Aramco determines that any excavation or embankment or fill on Saudi Aramco property which was created by a Contractor and which is a hazard to life and limb, or endangers property, or adversely affects the safety, use or stability of a roadway or drainage channel, the responsible contractor, upon receipt of a notice in writing from Saudi Aramco, shall immediately repair or eliminate such excavation or embankment so as to eliminate the hazard.

Fill and backfill materials shall be from either on-site excavation, designated borrow areas, or off-site sources conforming to the following criteria or as recommended by a geotechnical report. All borrow material and its source of supply shall be approved by Saudi Aramco. Stockpiles of cohesive soil shall be protected from freezing. Fill or backfill materials shall meet the requirements given in Sections 6. As a minimum, 'Select Fill Material' shall be used within 0.

Foundations may be constructed directly on undisturbed soil. Excavation of undisturbed soil and replacement with Select Fill Material should not be performed except as noted in 7. The maximum size of the fill material shall be one-half the lift thickness or 75 mm 3 inches , whichever is less.

Fill material shall be free of frozen lumps, organic matter, trash, chunks of highly plastic clay or other unsatisfactory material. That portion of the material passing the No. Clean sand and dune sand can be used as Select Fill Material. If sand is used as fill material, see Paragraphs 6. Water used for compaction of fill material shall be reasonably free of salts, oil, acid, alkalis, organic matter, or other deleterious substances.

Use of water with a TDS in excess of 10, ppm such as brackish water, seawater or water obtained from ground pits such as subkha water is not allowed unless it is proven and verified by the Company Representative and the Project Inspection Representative that there is no other source of water available within 20 km and all concrete to be supported by or buried within the fill is designed for either Exposure Type II or III as defined in SAES-Q Table 1.

The compaction water TDS requirements do not apply to fill or backfill which will be below the surrounding area natural water table.

Stripping shall consist of the excavation, removal, and satisfactory disposal of all topsoil and soil containing organic material or excessive. Such material shall not be used as fill material under any circumstances.

Proof roll may be defined as crossing the area with a heavy minimumton weight rubber-tire or steel-wheel roller. The density of the top 6 inches mm in these areas shall not be less than that required in paragraph 6.

Compaction shall be performed with equipment compatible with soil type. Fill materials shall be placed in lifts not exceeding mm 4 in in loose depth for hand-operated compaction. Other lift thicknesses may be approved by the appropriate Saudi Aramco Inspection Representative based on a field test section using the intended compaction equipment.

Every effort shall be made. When the backfill material cannot clearly be classified as cohesive or cohesionless both relative density and Proctor density tests must be performed per the above paragraph.

The backfill shall then be compacted to the greater density. However, flooding may be used if the fill material is cohesionless freely draining sand. Water flooding may be the most effective compaction technique for poorly graded and single-size sands, as these.

A series of horizontal benches, steps, or terraces, at least 10 feet mm wide, should be cut into existing and natural slopes prior to adding new fill. Construction of new slopes shall be accomplished by compacting horizontal fill layers at least 1 roller width beyond the design edge of the slope and then trimming back to achieve the final slope dimensions.

A cap layer of compacted cohesive material to mm 6 to 12 in in thickness will generally be sufficient. The capping material shall have a maximum liquid limit of 35 and a maximum plasticity index of 12, per ASTM D Acceptance testing of in-place density and moisture content field density testing on compacted fill will be performed at the following rates: 1. Backfill of trenches - one test for every 50 linear ft 15 m of each lift. The number of tests shall be increased if a visual inspection determines that the moisture content is not uniform or if the compacting effort is variable and not considered sufficient to attain the specified density.

The Project Inspection Representative may approve a decrease in the number of tests once a compaction procedure has proven to meet compaction requirements. The base course for roads, parking areas, and other areas to be surfaced shall be prepared in accordance with SAES-Q Structural excavation shall include excavations for footings, grade beams, pits, basements, retaining walls, man holes, catch basins, pipeline thrust anchors, etc. Earthen structures include permanent work items such as ponds, canals, ditches, etc.

Excavation for such work shall be made to the lines, grades, and cross sections as shown on the drawings. Unstable soil in the slopes shall be removed and the slopes properly prepared as described in Section 6. The bottoms of excavations shall be graded to the elevations and configurations as shown on the drawings. Seismic velocities will be the sole factor in determining the appropriate category for the excavation of rock.

Excavation of rock will fall into the following categories, based on the seismic velocities measured in the field by refraction seismic testing. All excavated materials that are unsatisfactory for use as fill or backfill or that are surplus to that needed for backfilling shall immediately be disposed of at a location designated by the Saudi Aramco Company Representative.

 Танкадо. Сьюзан едва заметно кивнула: - Он требовал, чтобы мы сделали признание… о ТРАНСТЕКСТЕ… это стоило ему… - Признание? - растерянно прервал ее Бринкерхофф.  - Танкадо требует, чтобы мы признали существование ТРАНСТЕКСТА. Но он несколько опоздал.

Секунду спустя машина остановилась рядом с. - Мисс Флетчер! - раздался изумленный возглас, и Сьюзан увидела на водительском сиденье электрокара, похожего на те, что разъезжают по полям для гольфа, смутно знакомую фигуру. - Господи Иисусе! - воскликнул водитель.  - С вами все в порядке.

Шестнадцать часов. Но это не все, сэр. Я запустил антивирус, и он показывает нечто очень странное. - Неужели? - Стратмор по-прежнему оставался невозмутим.  - Что показалось тебе странным.

Сьюзан собралась с мыслями и шагнула в дверной проем.

Коммандер был вынужден принимать невероятные решения, совершать чудовищные поступки, на которые, как ему казалось раньше, не был способен. Это единственное решение. Единственное, что остается.

Это цена, которую приходится платить за известность. - Действительно.  - Клушар вздохнул с видом мученика, вынужденного терпеть всякий сброд.  - Вы когда-нибудь видели что-либо более ужасное, чем это место? - Он обвел глазами палату.

Ее мозги работали словно на совсем другом уровне. Она подавляла его своей красотой, и всякий раз, когда он оказывался рядом, язык у него заплетался. Сейчас она держалась подчеркнуто сдержанно, и это пугало его еще сильнее. - Так в чем же проблема, Фил? - спросил Стратмор, открывая холодильник.  - Может, чего-нибудь выпьешь.

В кромешной тьме вокруг ей виделись чьи-то лица. На полпути к ТРАНСТЕКСТУ тишина шифровалки нарушилась. Где-то в темноте, казалось, прямо над ними, послышались пронзительные гудки.
