PROJECT DEFINITION & SCOPE Chapter (1) PROJECT DEFINITION & SCOPE Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 4 - Architecture Consultant: Raafat Miller Consulting (RMC) HHCP,inc MEP Consultant : Raafat Miller Consulting (RMC) 1.4 Contract Type A Unit Price Contract is a type of contract based on estimated quantities of items and unit prices (rates: hourly rates, rate per unit work volume, etc.). In general, the contractor’s overhead and profit is included in the rate. The final price of the project is depending on the total quantities needed to carry out and complete the work. The Unit Price Contract is only suitable for well-known resources involved project but unknown quantities at the time of the contract which will be defined when the design and engineering or construction work is completed. 1.5 General Layout Fig.( 1.3 ): Ground Floor Layout Chapter (1) PROJECT DEFINITION & SCOPE Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 5 - 1.6 Project scope The project consists of four buildings which are split into sections according to construction joints: Building A has 7 sections, Building B and C have 5 sections and Building D has 6 sections Each of the four buildings is a structure of basement, ground level and two more floors: -The basement is going to be used for the parking area -The ground level is for cafes, restaurants and food courts -The upper floors are for the retail stores, offices and entertainment areas 1.7 Work Scope  Side supports: - Retaining Walls - Anchors - Piles (CFA & Bored Piles)  Foundation: - Isolated Footings with smells  Skeleton: - Columns - Beams - Flat slabs with dropped panels  Finishing: - Different layers of finishing from plasters to paintings - 6 - 2. CONTRACT ANALYSIS Chapter (2) CONTRACT ANALYSIS Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 9 - The project delivery method is: EPC It stands for Engineering, Procurement, Construction and is a prominent form of contracting agreement in the construction industry. The engineering and construction contractor will carry out the detailed engineering design of the project, procure all the equipment and materials necessary, and then construct to deliver a functioning facility or asset to their clients. Companies that deliver EPC Projects are commonly referred to as EPC Contractors. Fig.( 2.1 ): EPC contract hierarchy Advantages of EPC contract: 1. EPC contractor is responsible for the implementation process of project. This could help the planning and collaborative operation of the overall project. 2. Effective solution of connection problem between design and construction, reducing the intermediate link between purchasing and construction. 3. The limit between working range and responsibility is clear. 4. General contractor is the responsible for risk during the construction period. 5. The advantages of project management could be showed, realizing the various objectives of project management. 6. The total prices and duration of the contract are fixed. This could help the control of expense and progress. 7. The owner could be free from the specific and the pay attention to the important factors influencing the project, finally ensuring the general direction of project management. Chapter (2) CONTRACT ANALYSIS Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 10 - Disadvantages of EPC contract: 1. The owners seldom participate in the project, and the control degree is also low for the owners. 2. EPC companies are responsible for risk, so it's important to choose the right EPC companies. As if the EPC companies have the serious financing problems, the project will be at risk. 3. The cost of EPC companies will be higher for the owner due to risk responsibility. 4. More information about EPC companies could be found in this site as the owners of the traditional construction mode will be more difficult to understand the works of the EPC companies. 2.3 Contractor selection method Direct Order method was used by the owner to select ATRIUM as EPC contractor to execute this project because: Both Owner and ATRIUM belong to TMG Both had achieved several projects together ATRIUM is well known contractor Suitable method to save time instead of the traditional method of tendering 2.4 Classification of contract conditions Contract conditions can be classified to 3 main conditions: Financial conditions. Legal conditions. Technical conditions. Chapter (2) CONTRACT ANALYSIS Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 11 - 2.5 Financial conditions compared to FIDIC 1- Changes in cost Contract condition No adjustment to the Contract Price shall be made in respect of any increase or decrease in the cost to the Contractor of goods and materials (whether for Permanent or Temporary Works), consumable stores or Plant or in the cost to the Contractor of ocean or air freight and other associated charges which may take place subsequent to the date of Tender. FIDIC clause Not mentioned Comment The contract is not shown to use this ratio to reverse reference model contractor obligation. 2- Delays and Cost of Delay of Drawings Contract condition If, by reason of any failure or inability of the Contract Administrator to issue, within a time reasonable in all the circumstances, any drawing or instruction for which notice has been given by the Contractor, the Contractor suffers delay and/or incurs costs then the Contract Administrator shall, after due consultation with the Employer and the Contractor, determine: (a) any extension of time (b) the amount of such costs, which shall be added to the Contract Price and shall notify the Contractor accordingly, with a copy to the Employer. FIDIC clause The same clause Comment The contract is not shown to use this ratio to reverse reference model contractor obligation. Chapter (2) CONTRACT ANALYSIS Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 14 - (b) the Contractor has marked the Plant and/or Materials as the Employer’s property in accordance with the Engineer’s instructions. Comment Same as FIDIC 2.7 Technical conditions compared to FIDIC 1- Valuation of Variations Contract condition The difference: The value of any variation shall be agreed by the Contractor and Contract Administrator, within a period of 90 days from the issue date of the formal instruction, unless otherwise instructed by the Contract Administrator. Should the Contractor fail to agree the value within the stipulated period, the Contract Administrator, shall determine the value as noted above, which value shall be final and binding. The Contractor shall employ a dedicated cost management resource to service the valuation of any variation in accordance with this Clause. This resource will be separate from the Contractor's internal cost reconciliation team. The primary duties of the cost management resource will comprise: (i) the provision of cost estimates for potential variations; (ii) the collection of Subcontractor and suppliers' costs; (iii) the preparation of individual variation cost submissions; (iv) the preparation of the monthly statements of account for progress payments; (v) preparation of final account; and (vi) any other duties as agreed. FIDIC clause All variations referred to in Clause 51 and any additions or deletions to the Contract Price which are required to be determined in accordance with Clause 52 (for the purposes of this Clause referred to as "varied work"), shall, subject to Clause 52.2, be valued at the rates and prices Chapter (2) CONTRACT ANALYSIS Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 15 - set out in the Contract if, in the opinion of the Contract Administrator, the same shall be applicable. If the Contract does not contain any rates or prices applicable to the varied work, the rates and prices in the Contract shall be used as the basis for valuation so far as may be reasonable, failing which, after due consultation by the Contract Administrator the Employer and the Contractor, suitable rates or prices shall be agreed upon between the Contract Administrator and the Contractor. In the event of agreement, the Contract Administrator shall fix such rates or prices as are, in his opinion, appropriate and shall notify the Contractor accordingly, with a copy to the Employer. Until such time as rates or prices are agreed or fixed, the Contract Administrator shall determine provisional rates or prices to enable on-account payments to be included in certificates I issued in accordance with Clause 60. Comment Varied quantity doesn’t exceed 10% 2. Inspection of Site Contract condition The Contractor shall be deemed to have inspected and examined the Site, its surroundings and all other places where the Works are to be performed and to have satisfied himself before submitting his Tender as to the form and nature thereof, including, as far as is practicable, the sub-surface conditions, the hydrological and climatic conditions, the extent and nature of work and materials necessary for the completion of the Works and the remedying of any defects, the Laws, procedures and labour practices of the Country, the Contractor's requirements for access, accommodation, facilities, personnel, power, transport, water and other services and in general,' §hall be deemed to have obtained all necessary information as to risks, contingencies and all other circumstances which may influence or affect his Tender or the performance of the Works. FIDIC clause The Contractor shall, within28 days the time stated in of these Conditions 8/1 after the date of the Letter of Acceptance, submit to the Engineer for his consent programme, in such form and detail as the Engineer shall reasonably prescribe, for the execution of the Works. The Contractor shall, whenever required by the Engineer, also provide in writing for his information a general description of the arrangements Chapter (2) CONTRACT ANALYSIS Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 16 - and methods which the Contractor proposes to adopt for the execution of the Works. Unless the engineer - within (21) days from the date of receipt of the program - to comment upon and inform the contractor about the extent of non-matching program for a decade, then equal right to the implementation of which, considering its other obligations under the contract. As members of the employer is entitled to base on that program when planning to perform their activities Comment Contract pilot was not clear in this clause. There is a condition in the Contract is an obligation on insurance companies Chapter (2) CONTRACT ANALYSIS Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 19 - Administrator, Should the Contractor fail to agree the value within the stipulated period, the Contract Administrator, shall determine the value as noted above, which value shall be final and binding. The Contractor shall employ a dedicated cost management resource to service the valuation of any variation in accordance with this Clause. This resource will be separate from the Contractor's internal cost reconciliation team. The primary duties of the cost management resource will comprise: (i) the provision of cost estimates for potential variations; (ii) the collection of Subcontractor and suppliers costs; (iii) the preparation of individual variation cost submissions; 2.9 Beneficial Payment of Subcontractors 4.7 ii) The Contractor shall pay its Subcontractors in accordance with the terms of their respective subcontracts. (a)If it comes to the attention of the Employer that the Contractor has not complied with Clause1, the Employer reserves the right (at its sole discretion), to pay direct to the relevant Subcontractor, on the receipt of an invoice issued by the Subcontractor addressed to the Employer, part or all of such amounts which are due to the Subcontractor as noted in the invoice. The Employer may at any time request evidence that amounts due to the Sub Contractor are paid by the Contractor. (b) The Employer shall deduct any payment made pursuant to Clause 4.7(a) from any sums owing to the Contractor and such payment shall be considered to have been a payment made to the Contractor in respect of the part of the Works to which it relates. (c) The Contractor agrees that any payment made pursuant to this Clause will be without any risk to the Employer and shall not create any contractual relationship between the Employer and the Subcontractor. The Contractor indemnifies the Employer in respect of any claims made by any Subcontractor as a result of the Employer exercising its right pursuant to Clause 4.4 and this Clause 4.7. Chapter (2) CONTRACT ANALYSIS Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 20 - 2.10 Collateral/Security Disruption of Progress 6.3 The Contractor shall give, not less than twenty eight (28) calendar days, written notice to the Contract Administrator whenever planning or progress of the Works is likely to be delayed or disrupted unless any further drawings or order including a direction, instruction or approval, is issued by the Contract Administrator within a reasonable time. The notice shall include details of the drawing or order required and of why and by when it is required and of any delay or disruption likely to be suffered if it is late. Failure to comply with this clause shall relieve the Contract Administrator from the obligation to consider any claim by the Contractor. Unforeseeable Physical Obstructions or Conditions 12.2 If during the execution of the Works the Contractor encounters physical obstructions or physical conditions, other than climatic conditions on the Site, which obstructions or conditions were, in his opinion Unforeseeable, the Contractor shall forthwith give notice thereof to the Contract Administrator, with a copy to the Employer This notice shall describe the physical conditions, so that they can be inspected by the Contract Administrator, and shall set out the reasons why the Contractor considers them to be Unforeseeable. The Contractor shall continue executing the Works, using such proper and reasonable measures as are appropriate for the physical conditions, and shall comply with any instructions which the Contract Administrator may give. On receipt of such notice, the Contract Administrator shall, if in his opinion such obstructions or conditions are Unforeseeable, after due consultation with the Employer and the Contractor, determine: (a) any extension of time to which the Contractor is entitled under Clause 44, and (b) the amount of any costs which may have been incurred by the Contractor by reason of such obstructions or conditions having been encountered, which shall be added to the Contract Price, and shall notify the Contractor accordingly, with a copy to the Employer. Such determination shall take account of any instruction which the Contract Administrator may issue to the Contractor in connection therewith, and any proper and reasonable measures acceptable to the Contract Administrator which the Chapter (2) CONTRACT ANALYSIS Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 21 - Contractor may take in the absence of specific instructions from the Contract Administrator. However, before additional Cost is finally agreed or determined under sub-paragraph (b) above, the Contract Administrator may also review whether other physical conditions in similar parts of the Works (if any) were more favourable than could reasonably have been foreseen when the Contractor submitted the Tender. If and to the extent that these more favourable conditions were encountered, the Contract Administrator may proceed to determine the reductions in cost which were due to these conditions, which may be included (as deductions) in the Contract Price and Interim Payment Certificates. However, the net effect of all adjustments under sub-paragraph (b) and all these reductions, for all the physical conditions encountered in similar parts of the Works, shall not result in a net reduction in the Contract Price. Failure to Give Possession 42.2 If the Contractor suffers delay and/or incurs costs from failure on the part of the Employer to give possession in accordance with the terms of Sub-Clause 42.1, the Contract Administrator shall, after due consultation with the Employer, and the Contractor, determine: (a) any extension of time to which the Contractor is entitledunder Clause 44; and (b) the amount of such costs, which shall be added to the Contract Price and shall notify the Contractor accordingly, with a copy to the Employer. Chapter (3) WBS & OBS Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 24 - Fig.( 3.1 ): WBS Chapter (3) WBS & OBS Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 25 - 3.2 OBS definition Organization Breakdown Structure or OBS is a hierarchical model describing the established organizational framework for project planning, resource management, time and expense tracking, cost allocation, revenue/profit reporting, and work management. The Organization Breakdown Structure groups together similar project activities or “work packages” and relates them to the organization’s structure. OBS (also known as Organizational Breakdown Structure) is used to define the responsibilities for project management, cost reporting, billing, budgeting and project control. The OBS provides an organizational rather than a task-based perspective of the project. The hierarchical structure of the OBS allows the aggregation (rollup) of project information to higher levels. When project responsibilities are defined and work is assigned, the OBS and WBS are connected providing the possibility for powerful analytics to measure project and workforce performance at a very high level (example business unit performance) or down to the details (example user work on a task). - 26 - 4.

The anchors provide forces for the stability of the sheet pile, in addition to the lateral passive resistance of the soil into which the sheet piles are driven. It includes an anchor or tieback at or near the head of the wall. More than one set of anchors or tiebacks can be used. It increases wall stability and enables taller walls to be built and sustained almost a necessity with vinyl, aluminium and fiberglass sheet piles. It is not exclusive to sheet piling; also used with other types of in situ wall systems. In case of cantilever sheet pile walls if the deflection at top point of the sheet pile wall is very large, then settlement of soil takes place at top just behind the sheet pile wall. So, to reduce the excessive deflections the anchors are provided. The angle of internal friction, which is an empirical shear strength parameter of the soil, plays a major role in the resistance of the load carried by the ground anchor. Also, when it is installed to a greater depth, the frustum of cone of soil supporting the anchor is also large, which gives more force-resistance. Also, when small loads are applied the depth can be less. But if the load is of higher range, sufficient additional anchors (or) greater length is to be provided. The diameter of the anchor also plays a bigger part. The size and angle of the top surface of ground anchor is a useful parameter in the installation and pull-out resistance of the ground anchor. Components and Principle of Ground Anchor in Construction The following are the different components of the Ground Anchor 1. Wedge Plate 2. Individual Sheathing 3. Bearing Plate 4. Wedge 5. Strands 6. Spacer 7. Grout body The stiffness of the wedge plate is useful in transmitting the anchor load to the bearing plate closer to the ends of the plate’s span. This prevents the bending of the bearing plate. If you have large size wedge plate, then the amount of bending of the bearing plate is reduced. Strands are useful in tying up all the cables and act as one unit. The wedge prevents the anchor part from sliding and thus keeps the ground anchor in position. Grout body is useful in maintaining a bond between the anchor and the soil. Chapter (4) METHOD STATEMENT Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 35 - How to Determine the Reasonable Position and Length of the Ground Anchor This problem arises in slope reinforcement projects. One of recent method used to calculate the above is the variable- modulus elastoplastic strength reduction method or simply called as the SRM. This method is used to obtain the stress variations, strain field, factor of safety of the slope. In this method, slope- stability done by anchor cables is modeled using surface loading. To represent the anchor reinforcement system, they are distributed in different forms of surface loading.

The dimensions and alignment of R.C components and formworks should be inspected by the site engineer. Steel reinforcement should be placed and its alignment & number of steel bars should be revised according to the drawings. Ensure that the concrete delivery vehicles have suitable access to the intended areas in the suitable time. Ensure that the quality of concrete is suitable and proper, tests such as slump test should be made. Concrete is poured using a pump followed by a worker with a vibrator for the compaction of the concrete. Surveying instruments and level should be set up during the pouring to ensure the formwork states. Cubes of the designed mix must be tested for compressive strength at 7 days and 28 days for the initial approval satisfying a 400 kg/cm2 compressive strength. The structure should be checked after the pour, line and levels should also be verified. -Risk assessment: Incidents that could happen as a result of poor planning. Unsuitable equipment locations which can cause several accidents. Collapse of work area. Live electrical lines in working area. Injury through failure of equipment. Vehicle damage. Personnel struck by hoses or concrete Working in extreme weather conditions. Chapter (4) METHOD STATEMENT Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 40 - -Formwork: After studying the structural drawings, the Project Engineer will plan for sizes, numbers and type of formwork to be used in consultation with the Structural Engineer, if required. Depending upon the program, the number of repetitions will be decided. Availability of formwork will be checked with the Procurement Manager and decision will be taken to buy, hire or reuse formwork material. During fabrication of formwork shutters, all dimensions shall be cross-checked with a view to avoiding corrective action during erection. Paint reference numbers on all panels to ensure their use in correct positions. Ensure that the props, shores, waling, bearers, clamps and tie rods are the right size and at the correct spacing. The Formwork designer shall check the false work system with respect to load imposed on it and design parameters as laid down in the specification. Check that the false work is securely braced and is on a firm foundation. Forms fastened to previously cast concrete must be tightly fixed to prevent grout loss. Cellular foam plastic strips can be used to make a seal. Check quality of shutter lining, tightness of bolts and wedges, built-in items, inserts and other embedment. Tie-rod holes to be made in the formwork shall be neat so that they can be patched or plugged later on. Particular attention will be paid to the rigidity and line of stop ends and joint formers. Remove all tie-wire clippings and nails, which may stain both the formwork and the concrete. Ensure that adequate access and working platforms are in place for the concreting gang and that toe boards and guardrails are provided. A spreader or lifting beam shall be used to prevent distortion when placing formwork. Adjustable steel props shall be erected in plumb and verticality of props checked using a spirit level. A prop should not be used if it is bent, creased or, rusted or has a bent head or base plate, damaged pin etc. Proper release of agent shall be used so that it can be removed without damaging the surface finish of the concrete. New timber and plywood forms shall be given first coat of the appropriate release agent 36 hours in advance, then a second coat just before they are used. Chapter (4) METHOD STATEMENT Graduation Project 2019 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ - 41 - Avoid excessive use of release agent as this can cause staining or retardation of the concrete. A close watch should be kept on all wedges and fastenings. Make sure that they do not work loose. Grout loss is an indication that some movement has occurred. 4.3.4 Finishing Brick works: Lines and levels should be set out and datum's marked whenever possible. Material should be stacked as close to working site as possible. Materials used are: Perforated bricks, light bricks, cement hollow and solid blocks connected using a binding mortar. Binding mortar will be mixed on site to ensure consistency. Levels and line checks will be performed periodically during works. For masonry works underground bricks will be insulated using liquid bitumen. -plastering: Plastering will be done on three stages: Spattering: Cleaning the wall surface from dust, and other roughness, then sprinkle it with water & smoothing the surface, with a steel brush, Sprinkle mortar cement to the walls using trowel. Level dots & strings: It is made by gypsum. Thickens of dots equals to the thickness of plastering layer. Plastering: Sprinkle the walls with water. Fill between the strings with mortar Level the surface. 4.4 Application of Method Statement On The Project The following tables include an application of method statement on some of the project activity.
