Subcontractor Alleges Fraud for Scope Reduction on DOT Contract
A contractor that reduces a subcontractor's scope of work is well within its rights if the contract explicitly allows the change....

Grouting Methods
This chapter discusses common grouting methods used in underground applications in both soil and rock. Jet, compaction, permeation, and hydrofracture grouting methods are frequently used...

Maximum Weighted Log-Likelihood Estimation for Parameterization Selection Uncertainty
Hydraulic conductivity identification remains a challenging inverse problem in groundwater modeling because of inherent non-uniqueness and lack of flexibility in parameterization methods....

Groundwater Transport Modeling Using Fuzzy Sets and Fuzzy Logic
Modeling of groundwater flow and transport is inherently uncertain. The predictive capability of the model depends upon both the quantity and quality of hydrogeologic data. The introduction...

Viral Fate and Transport Modeling under Salinity Impact
This research studied the impact of salinity on sorption and transport of MS-2 in saturated sand through one-dimensional column experiments. MS-2 was used as a surrogate to understand...

Effects of Impervious Area Estimation Methods on Simulated Peak Discharges
The variability of simulated flood discharges is evaluated using two methods for estimating impervious surfaces and common design methods in the Mission Creek watershed (31 sq km) located...

Design-Build Contract Complexities
There are many approaches or options that an owner may pursue in acquiring facilities. Depending on the owner's objectives, the DB project approach may offer unique benefits,...

Project Definition and Conceptual Design
In order to select a DB contractor, the owner must define its requirements for project implementation and for the completed project. These requirements are typically incorporated into...

Preparing the Request for Proposals
Discussions with experienced DB contractors indicate that one of the most important aspects (if not the most important aspect) of a successful DB project is proper planning prior to issuing...

General Terms and Conditions
DB commercial contract terms can differ from conventional design-bid-build project terms, depending primarily on the owner's objectives, the level of risk that is to be assigned...

Specifications for Design-Build Projects
This chapter discusses the various specifications that come with a design-build project, including owner-generated specifications and contractor-generated specifications....

Geo-Denver 2007
New Peaks in Geotechnics
Proceedings of Geo-Denver 2007, New Peaks in Geotechnics, held in Denver, Colorado, February 18-21, 2007. Sponsored by the Geo-Institute of ASCE. This collection contains nearly 300 papers...

Roles and Responsibilities
This section summarizes the roles and responsibilities of the parties involved: owner, design team, contractor, construction manager, and dispute adjudicators....

Contributing Factors
This chapter examines contributing factors of the hurricane protection system failures, including the underappreciated risk to New Orleans, a piecemeal implementation of the hurricane...

Stochastic Analysis of the Truckee River Flow System
The Truckee River system is a complex system that involves a number of hydraulic structures such as natural and artificial lakes and reservoirs and diversions. Streamflow data have been...

The Best Alternative
The City of Portland, Oregon, is using a hybrid contracting scheme that combines the scheduling advantages of design/build with the control of a construction manager arrangement to construct...

Firepower
The processes put in place by water utilities are designed with the quality of water normally received for treatment in mind. But the runoff from areas ravaged by fire can degrade that...

Case Studies in Steel
An innovative project delivery system for structural steel buildings enables the structural engineer to provide complete structural design services on conventional contractor-led design/build...

Water Treatment Plant Design
Let a team of water treatment plant design experts . with contributions from more than 30 international authorities -- give you comprehensive guidance on modernizing existing water treatment...
