(2019-05-08)In construction projects whether small or large scale, in the design and construction phases, contractors and owners face numerous reworks which finally leads to schedule delays and cost overruns. Although studying the ... -
Identifying Issues Impacting Productivity Of Box Jacking Projects
(Civil & Environmental Engineering, 2013-03-20)Jacking is a trenchless construction technique used for installing underground pipeline system. Jacking method is more widely used for upgrading under capacity culverts and drainage structures under roads and railroad ... -
Identifying the Optimal Combination of Critical Roadside Slope Segments Susceptible to Rainfall-induced Failures for Minimizing Vulnerability of Highway Networks
(2022-08-11)The stability of roadside slopes is vital for the smooth operation of the highway transportation system. The failure of slopes adjacent to the highway corridors adversely impacts the network users and network operators. ... -
Impact Of A Pre-combustion Retrofit Device On Vehicular Emissions: A Case Study
(Civil & Environmental Engineering, 2007-08-23)Vehicular emissions are a major cause of air pollution in the cities worldwide. Increased numbers of vehicles and the vehicle miles traveled by them every year means that the emissions are going to have a detrimental effect ... -
Impact Of Lateral Swell Pressure On Retaining Structure Design Using Expansive Cohesive Backfill
(Civil & Environmental Engineering, 2008-08-08)Since cohesive soils are difficult to drain once becoming saturated, in order to reduce lateral earth pressures exerted by saturated cohesive soils on retaining structures, retaining wall designs most always specify use ... -
The Impact Of Lime Dosage On Odor Reduction Of Biosolids
(Civil & Environmental Engineering, 2014-12)The amount of boisolids production is increasing due to developing cities and the mitigation of biosolids odorants is a key role to have a successful biosolids land application program. The objective of this study is to ... -
Impact Of Transit-oriented Infrastructure Investments on Property Valuations
(Civil & Environmental Engineering, 2012-04-11)The population explosion of the second half of the last century brought about increased human activity. Much of the attendant increased access to activities has been facilitated by the incredible technological advances in ... -
IMPACT OF WEATHER FACTORS ON GO-AROUND OCCURRENCE
(2016-05-10)A “go-around” occurs when an aircraft, which is on final approach, aborts it landing due to unsatisfactory conditions. Go-arounds have a significant impact on the capacity of the airports and pose a serious concern at large ... -
IMPACT OF WET-DRY CYCLE ON MECHANICAL PROPERTIES OF EXPANSIVE CLAY UNDER LOW OVERBURDEN STRESS
(2016-09-16)The seasonal variation in the water content termed as drying-wetting cycle is one of the most important environmental factor that may cause the degradation of strength for expansive clay. Highway embankment within the north ... -
