Materials approved at the manufacturing plant will be subject to visual acceptance inspections at the jobsite or point of delivery. 701.03 EXCAVATION. For all trench excavation, ensure that the sides of the trench are stable, as evidenced by the sides of the trench being able to maintain a vertical cut face. Consider the sides unstable if fissures develop in the face of or adjacent to the open excavation; if the edge of the excavation subsides; if material ravels, spalls, or slumps from the face of the excavation; or if the bottom of the excavation bulges or heaves. In all cases of apparent distress, or when the trench excavation exceeds 5 feet in depth, sloping, benching, and shoring will be required in accordance with the OSHA trench safety standards, 29 CFR § 1926 (P). Consider these and any more stringent trench safety standards as minimum contract requirements. Submission of bid and subsequent award of contract will serve as certification that all trench excavation in excess of 5 feet will be in compliance LA R.S. 48:251.1. Consider all available geotechnical information when designing the trench excavation safety system, including groundwater. Evaluate trench stability due to the effects of surcharge loads from adjacent structures, stored materials and equipment, or traffic. Ensure that excavated material is placed a sufficient distance back from the trench edge to preclude material from falling back into the trench, otherwise provide an adequate retention system. Ensure that the bottom width of a pipe trench provides at least 18 inches of clearance on each side of the pipe. In accordance with 202.02, satisfactorily dispose of surplus excavated material that does not conform to the requirements of 203.06.1. Control rainfall runoff or excess moisture by proper selection of backfill materials, dewatering sumps, wells, well points, or other approved

  • FHBRO Heritage Character Statement
    HERITAGE CHARACTER STATEMENT Page 1 FHBRO Number 96-51 Kingston, Ontario Redoubt FINAL DRAFT Fort Henry The Redoubt, the main work of Fort Henry, was constructed between 1832 and 1836 for the Master General, Board of Ordnance. A six-sided casemated fortification, the redoubt, was built to observe and defend the glacis on the north-west front, dominate the eastern approaches to the dockyard and naval and commercial harbour of Kingston, command the entrance to the Rideau Canal, defend the dry ditch on all faces, and provide bomb-proof space for barrack accommodation, the storage and shifting of gunpowder and other support activities. The redoubt was the work of two members of the Corps of Royal Engineers: Lieutenant Colonel Gustavas Nicolls, who produced the design and Lieutenant Colonel Ross Wright, who oversaw the construction. External modifications include: the diverting of water from the valleys between the dos d’ânes of the casemates into internal cast iron vertical pipes and the blocking up of the original gargoyles (1844-46), the replacement of the 24-pdr. SBML gun in the north-east angle with an 8-inch shell gun on a common traversing platform (1845), the dismounting of nine 24-pdr. guns (1859), the sheathing of the superior slope of the parapets in pine boards (1861-64), the replacement of the 8-inch shell gun with a 7-inch (11 0-pdr.) Armstrong Gun RBL (1875), the demolition of the west curtain (1895), the covering of the terreplein with a built-up roof and the re-sheathing of the superior slope of the parapets (1914-1 5), the

  • The Milton Blockhouse, Gravesend: Research and Excavation
    http://kentarchaeology.org.uk/research/archaeologia-cantiana/ Kent Archaeological Society is a registered charity number 223382 © 2017 Kent Archaeological Society THE MILTON BLOCKHOUSE, GRAVESEND: RESEARCH AND EXCAVATION. VICTOR T.C. SMITH, B.A. INTRODUCTION This is the third report of the Kent Defence Research Group of the Kent Archaeological Society. In the writer's paper 'The Artillery Defences at Gravesend', (Arch. Cant., Ixxxix (1974), 143) mention was made of Milton Blockhouse, one of five artillery blockhouses erected by Henry VIII to defend the Thames against a hostile fleet. It was suggested that this blockhouse had probably been built on a site at what is now the north-eastern corner of the Canal Basin, Gravesend (N.G.R. TQ 655743). Preliminary trenching in that area during 1973 had led to the discovery of substantial chalk foundations. Subsequently, addi- tional documentary research was undertaken and with the assistance of grants kindly given by the Gravesend Historical Society and the Kent Archaeological Society, and with the co-operation of the Gravesham Borough Council, further excavations under the writer's direction were carried out by the Kent Defence Research Group at intervals during 1974-8. The purpose of the excavations was to verify identification and to recover a basic plan which could be com- pared with the D-shaped Gravesend and Tilbury blockhouses, the plans of which were the only ones previously known of the five Thames blockhouses. This report sets out the documentary evidence and describes and discusses the results of the excavation. HISTORICAL BACKGROUND AND DOCUMENTARY EVIDENCE Early in 1539 provision was made for the building of the five Thames blockhouses near the mouth of the river where it first begins to narrow after the estuary.1 They were constructed in 1539/ 341 VICTOR T.

  • Notes on the Consolidation of Earthworks." by JULES GAUDARD,Civil Engineer, Lausanne (Translatedfrom the French by James Dredge, C.E.)
    21s THE CONSOLIDATION OF EARTHFVORKS. EO.1,274.-" Notes on the Consolidation of Earthworks." By JULES GAUDARD,Civil Engineer, Lausanne (Translatedfrom the French by James Dredge, C.E.). THEexecution of earthworks for roads, and more especially for railways, is frequentlyhindered by landslips, sometimes of so serious a nature as todefy all theresources of the engineer. In laying down the centre line of a road or of a railway, the regularity of the natural surface is not by anymeans the sole con- sideration. The attentionof the engineer has to becarefully directed to the natureof the ground; he must avoid, as faras possible, deep cuttingsin clayey soiIs, and, above all, in side-lying pound. Embankments, again, should not only be constructed of carefully- selected material,but they shouldbe formed upon a natural surface solid enough to carry their weight withoutset,tIement. It is easy to lay down rules for dealing with simple and well- defirled cases, but Nature for the most part presents complicated conditions for the engineer to control. Matter is not purely inert ; it possesses, so to speak, a certain chemical or physical life, which becomes gradually converted either into changeof material, or into motion. In the simple case of a cutting or a tunnel in rock, the sides of thecutting or the roof of thetunnel may be left unpro- tected,provided the rock is sufficiently solid. Butthere are materials which, appearing reliable at first, disintegrateunder atmospheric influences ; and natural steep sloping beds or strati& cations, which induce slips, are not unfrequently encountered. In such cases it is necessary either to give special inclinations to the faces of theearthworks, or to protect them with masonry.

FM 90-3 CHAPTER 1 THE ENVIRONMENT AND ITS EFFECTS ON PERSONNEL AND EQUIPMENT This chapter describes the desert environment and how it affects personnel and equipment. CONTENTS Page Section I The Environment . 1-1 Section II Environmental Effects on Personnel . 1-17 Section III Environmental Effects on Equipment . 1-30 Section I. The Environment Successful desert operations require adaptation to the environment and to the limitations its terrain and climate impose. Equipment and tactics must be modified and adapted to a dusty and rugged landscape where temperatures vary from extreme highs down to freezing and where visibility may change from 30 miles to 30 feet in a matter of minutes. Deserts are arid, barren regions of the earth incapable of supporting normal life due to lack of water. See Figure 1-1 for arid regions of the world. Temperatures vary according to latitude and season, from over 136 degrees Fahrenheit in the deserts of Mexico and Libya to the bitter cold of winter in the Gobi (East Asia). In some deserts, day-to-night temperature fluctuation exceeds 70 degrees Fahrenheit. Some species of animal and plant life have adapted successfully to desert conditions where annual rainfall may vary from O to 10 inches. Desert terrain also varies considerably from place to place, the sole common denominator being lack of water with its consequent environmental effects, such as sparse, if any, vegetation. The basic land forms are similar to those in other parts of the world, but the topsoil has been eroded due to a combination of lack 1-1 FM 90-3 of water, heat, and wind to give deserts their characteristic barren appearance.
