Scope of Planning Bridge

Scope of Planning Bridge
Bridge construction engineering planning essentially begins with the preparatory workthe initial planning and final planning that includes drawing plansbasicunderstanding of the specifications in the bidding documentsas well as the basis for calculating the estimated value engineering (engineering estimate), making a list of the quantity of currency payments in accordance with the specifications for can beused in the implementation of the bridge work. 

The scope of the Technical Planning Bridge Construction is discussed in this material are:
1. Definition of the bridgeBridge Construction
2. This type of data collection needed
3. Implementation of surveys and investigations
4. General requirements planning bridge
5. Bridge engineering planningconstruction and building
6. technical specificationsa bridge over building standards
7. The calculation of the quantity and cost analysis
With this material is expected to gain insight and understanding of the basics ofbridge engineering plans in accordance with the provisions and technical requirements that apply
Type and Building Standards Upper Bridgeconstruction of the bridge
To be able to carry out the construction of the bridge is faster since the design process to implementation of construction and building design to avoid errors that might occur over the bridgethen built a bridge over building standards that are tailored to the length bentangannya effectiveness.
Type of building the bridge that developed up to this time are:
 reinforced concrete Gelagar
 Gelagar prestressed concrete
 Gelagar composite steel
 Gelagar instead of composite steel
 Gelagar prestressed concrete box
 Steel Frame
 Suspension bridge
• cable stayed bridge (cable cancang)
 arch
 Beams arch

If not specifically designed, it can be used for building bridges of Highwaysstandards in accordance with the economic landscape, as follows:
 Gelagar Type Reinforced Concrete T-span 6 ms / d of 25 meters
 Gelagar prestressed concrete Type I and Box, spans 16 ms / d 40-meter
 Gelagar Steel Composites with spans 12 ms / d of 25 meters
 Frame of steel, spans 40 m s / d 60 meters

To bridge loading standards are divided into:
 Expenses BM 100 or 100% load with standard loading bridge
 Expenses BM 70 or the load with 70% standard loading bridge

Standard loading BM 100 is used to design a permanent bridge, for example:bridge construction with concrete or steel construction design plans age ≥ 50 years.
While the BM 70 is used to bridge non-permanent, for example: type of emergencybridge Bailley or Acrow panels, semi-permanent bridge.
Bridge Parts
The bridge consists of the parts and elementsEach element has a different functioncorresponding to the location and needs. Broadly speaking, the bridge can be divided as follows:
 Building UpperBroadly speaking
 Building Down
 Foundations
 Road approach
 Building Complementary
• Equipment
1. building Up
Is the first supporting structure load of traffic across the bridgeTraffic load on this bridge by building up will be passed down through the placement to buildings.Building the bridge consists of:

a. The main structure
 plate
 girder
 order
 hanging
 cable stayed (cable cancang)
 arch
 arch beam
b. floor systems
 floor
 longitudinal girder
 backrest
 pole backrest
c. Siar expansivity
 Broadcast steel expansion
 Broadcast rubber expansion
 Broadcast asphaltic plug expansion
d. cornerstone
 The cornerstone of steel
 Platform for rubber
 Platform for pot
