Target Market

Small to Medium Span Deck Type Bridges

Relates to analysis specialism rather than actual span

Linear static analysis


Product Overview

Target Market

Avoid discussions around long span suspension or

cable stayed projects

Most competitors offer a highly advanced but complex

bridge analysis

Not always suited to small to medium span deck type bridges

They also have a weak or non-existent code check

offering

Most high end systems used in conjunction with

spreadsheets to carry out code checks

Leads to complex, time consuming and disjointed

workflows

Position as a fully integrated product covering both Design

and Analysis

Provide much faster solution for smaller span deck type

bridges

Stress the code checking capability No other product goes to our level of detail

No need to spend time / money creating and maintaining spreadsheets

‘in-house’

Integrated tightly with analysis

Far more reliable than ‘in-house’ products, in-house solutions can contain

errors and omissions

ARUP is responsible for many world-leading

infrastructure design projects across the globe.

New contract won to design a series of new

prestressed concrete deck bridges

Design codes specified was unfamiliar to

Bridge Engineers on the project

Existing in-house developed design solution

deemed not adequate in terms of flexibility

and reliability

Designs required to a short timescale as

design cycle already started

Designs for prestressed concrete bridge

components successfully completed using

new design code

Efficient design workflow maintained though

successful collaboration with other team

members using legacy in-house solutions

Use of efficient workflows ensured timely

delivery of prestressed girder designs

Challenges Results


Sales Activities – Successes

Egis are a global multi-disciplinary consultancy

responsible for many prestigious infrastructure

design projects.

Producing preliminary and final designs was

perceived as an inefficient process

Producing code check work via

spreadsheets and other methods proved

troublesome

Potential upcoming projects specified using

an unfamiliar design code

New integrated system streamlined existing

workflows producing a very efficient design

cycle delivering preliminary and detailed

design effectively

Integrated code checking delivered reliable

designs quickly without the need for

protracted post processing

Code checking system with design

standards built-in allowed engineers to

produce design with an unfamiliar code and

aided code education
