Part - Civil Works Design You are required to undertake a civil construction design project as outlined below- Your Assessor will take the role of the client for the purposes of this assessment task- Design Specifications 1- The Problem You are a civil designer working for the state department of transportation- You have been assigned responsibility for the design of a truss bridge to carry a two-lane highway across the river valley shown below-   2- Design Objective Satisfy all of the specifications listed below, while keeping the total cost of the project as low as possible- 3- Bridge Configuration1- The bridge may cross the valley at any elevation from the high water level to 24 meters above the high water level-2- If the elevation of the bridge is below 24 meters, excavation of the river banks will be required to achieve the correct highway elevation-3- To provide clearance for overhead power lines -shown above-, the highest point on the bridge may not exceed an elevation 32-5 meters above the high water level -8-5 meters above the top of the river banks--4- The bridge may consist of either standard -simple supports- or -arch supports-- If necessary, the bridge may also use one intermediate , located near the centre of the valley- If necessary, the bridge may also use cable , located 8 meters behind one or both abutments-5- Each main truss can have no more than 100 and no more than 200 -6- The bridge will have a flat, reinforced deck- Two types of concrete are available: 1- Medium-strength concrete requires a deck thickness of 23 centimetres -0-23 metres--2- High-strength concrete requires a deck thickness of 15 centimetres -0-15 meter-- 7- In either case, the deck will be supported by transverse spaced at 4 metre intervals- To accommodate these floor beams, your must have a row of joints spaced 4 meters apart at the level of the deck- These joints are created automatically when you begin a new design-8- The bridge deck will be 10 meters wide, such that it can accommodate two lanes of traffic-4- Member Properties • Materials- Each member of the truss will be made of either carbon steel, high-strength low-alloy steel, or quenched and tempered steel-• - The members of the truss can be either solid bars or hollow tubes- Both types of cross-sections are square- • Member Size- Both cross-sections are available in a variety of standard sizes- 5- Loads The bridge must be capable of safely carrying the following loads: • Weight of the deck-• Weight of a 5-cm thick , which might be applied at some time in the future-• Weight of the steel floor beams and supplemental bracing members -assumed to be12-0 applied at each deck-level joint--• Weight of the main trusses-• Either of two possible truck loadings: • Weight of one standard H25 truck loading per lane, including appropriate allowance for the dynamic effects of the moving load- -Since the bridge carries two lanes of traffic, each main truss must safely carry one H25 vehicle, placed anywhere along the length of the deck--• Weight of a single 480 kN Permit Loading, including appropriate allowance for the dynamic effects of the moving load- -Since the Permit Loading is assumed to be cantered laterally, each main truss must safely carry one-half of the total vehicle weight, placed anywhere along the length of the deck-- 6- Structural Safety The bridge will comply with the structural provisions of the state specified standards, to include: • Material densities• Load combinations• Tensile strength of members• Compressive strength of members 7- Cost The cost of the design will be calculated using the following cost factors: • Material Cost: • Carbon steel bars - $4-50 per kilogram• Carbon steel tubes - $6-30 per kilogram• High-strength steel bars - $5-00 per kilogram• High-strength steel tubes - $7-00 per kilogram• Quenched and tempered steel bars - $5-55 per kilogram• Quenched and tempered steel tubes - $7-75 per kilogram • Connection Cost: $500-00 per joint• Product Cost: $1000-00 per product• Site Cost: • Reinforced concrete deck -medium strength- - $5,150 per 4-meter panel • Reinforced concrete deck -high strength- - $5,300 per 4-meter panel• Excavation - $1-00 per cubic meter -See the Site Design Wizard for excavation volume-• Supports -abutments and pier- - Cost varies -See the Site Design Wizard for specific values-o $6,000 per anchorage Required: 1- Make a detailed list of all constraints and requirements to the bridge design- 2- Prepare functional specifications 3- Present at least 2 designs to meet the design specifications- The designs are to include, as relevant: • calculations, which may include: • loads• sheer forces• bending moments• stresses• construction materials and services quantities• construction cost estimates • recommended sizing of components• recommended materials• recommended reinforcement sizing and location• drawings• risk assessment of: • the existing conditions• the application of the design• maintainability of the works • health, safety and environmental requirements• contribution to ancillary documentation, which may include: • design notes• construction notes• supplementary drawings• input to the specifications Note: The designs, and their development, should comply with relevant requirements including: • legislative, organisational and site requirements and procedures• manufacturer's guidelines and specifications• Australian standards• Code of practice• Employment and workplace relations legislation• Equal Employment Opportunity and Disability Discrimination legislation Attachment:- Civil Works Design-rar
