A critical process for the timely development and delivery of highway construction projects is the early identification and depiction of utility interests that may interfere with proposed highway facilities. The effective management of such utility interests or conflicts involves utility adjustment (or design changes), inspection, and documentation. The large number of stakeholders and the magnitude of the process result in enormous amounts of data. Despite substantial data exchange among utility accommodation stakeholders, few standards exist for exchange and management of utility data in the project development process. With sample data provided by the Texas Department of Transportation, research described in this paper addresses the issue of utility conflict management by analyzing specific utility conflict data flows and data needs of stakeholders. The paper presents the product of this analysis, which is a prototype system for managing utility conflict data called the Utility Accommodation and Conflict Tracker.

Detection of utility conflicts as early as possible during the project development process can help to substantially improve the timely relocation of utilities and can allow time to develop alternatives to avoid utility relocation. However, collecting accurate information on the location of underground utilities from utility companies can be challenging. This is one reason that subsurface utility engineering (SUE) has become a critical tool in helping to identify and locate utility installations within the right-of-way. Although the benefits of SUE have been well documented, a disconnect between its full potential and its actual use at the Texas Department of Transportation (DOT) was suspected. A survey of staff in diverse organizational units at the Texas DOT was conducted to learn about current utility investigation practices and to gain a better understanding of how the Texas DOT uses SUE. The team found, among other issues, some unfamiliarity with SUE technology and its best uses, a general need for training and education on the use of SUE, and a recent decline in the use of SUE technology that may be linked to frequent uncertainty about the benefits of SUE.

The Texas Department of Transportation (TxDOT), in partnership with the Center for Transportation Research, has implemented the Texas mobile load simulator (TxMLS) as a tool for accelerated testing of in-service pavements. Although the TxMLS has been used successfully to test in-service pavements in the Yoakum and Fort Worth districts, the fact that only one TxMLS machine exists limits the number of accelerated pavement tests (APT) that can be performed. Therefore, TxDOT is evaluating a modification of the rolling dynamic deflectometer (RDD) for use as a super-accelerated pavement tester. In this application, the truck-mounted dynamic loading system is operated in a stationary mode, with the loading rollers and rolling sensors of the RDD removed from operation. The servohydraulic actuator is used for application of harmonic loading to a wheel footprint on the pavement surface. Hundreds of thousands of load repetitions are applied in a matter of hours; hence the designation as super-accelerated testing. This stationary dynamic deflectometer (SDD) is being studied as a possible tool for use in expanding TxDOT’s APT program. The SDD may allow TxDOT to increase, in a cost-effective manner, the number of accelerated tests that can be performed. Preliminary tests have been performed with the TxMLS and SDD on two different pavement recycling strategies constructed on the northbound and southbound lanes of US-281 in the Fort Worth District. That the same conclusion was reached about the relative performance of the test sections with both machines indicates the potential usefulness of the SDD.

Reconstruction of the Dallas North Central Expressway is one of the largest construction projects undertaken by the Texas Department of Transportation. The $450 million, 18-km highway and light-rail corridor is being stage constructed under heavy commuting and Interstate traffic and a variety of strategies have been undertaken to mitigate the adverse impacts on traffic flow and businesses. The findings of various surveys conducted to evaluate the effectiveness of the business mitigation policies, including the impact on sales and access of business sales data reported to the state comptroller, an examination of multitenant occupancy rates for office space in the catchment area, and an analysis of businesses that either closed or opened are reported here. Somewhat surprisingly, more businesses opened than closed during construction. Recommendations are made on which policies can be utilized in other metropolitan areas of Texas and the United States.

The implementation of the construction project caused miscommunication, this made the contract became a reference during implementation. In the implementation of construction projects, there are often changes that not according to contract, for example: work volume changes, specifications changes, type or method of work changes, schedules changes , design changes, and others. These changes are commonly known as change orders. There are several things that cause a change order, for example: incompletable contract, design does not fit in the field, unsupportive weather, and others. This research is to determine the effect of change order in the aspects of cost, quality, and time in multi-storey building construction projects. Researchers used data from the responses of respondents consisting of contractors, consultants, and owners. The questionnaire made proposes several aspects of change orders and their effects on cost, quality, and time. Analysis of research data was carried out with the help of the SmartPLS 3.0 application program. The influence of change orders on costs is the lack of costs due to the addition of work items, while on quality is the quality decrease due to additional work volume, and on time is the delay in project completion due to changes in completed work.ABSTRAKPelaksanaan proyek konstruksi menyebabkan terjadi perbedaan pendapat yang disebabkan oleh pihak yang terlibat, hal ini membuat kontrak menjadi sangat penting dan menjadi acuan selama pelaksanaan. Pada pelaksanaan proyek konstruksi sering terjadi perubahan-perubahan yang akhirnya tidak sesuai dengan kontrak sebelumnya contohnya seperti: perubahan volume pekerjaan, perubahan spesifikasi, perubahan jenis atau metode pekerjaan, perubahan jadwal, perubahan design, dan lain-lain. Perubahan ini umum sekali terjadi dalam proyek konstruksi dan lebih sering dikenal sebagai change order.  Ada beberapa hal yang menyebabkan perlunya dilakukan change order, misalnya: kontrak yang dibuat tidak lengkap, design yang ada tidak sesuai dengan kondisi lapangan, cuaca yang tidak mendukung, dan lain-lain. Penelitian ini dilakukan untuk mengetahui besar pengaruh change order dalam aspek biaya, mutu, dan waktu dalam proyek konstruksi gedung bertingkat. Peneliti menggunakan data dari hasil tanggapan responden yang terdiri dari kontraktor, konsultan, dan pemilik. Kuesioner yang dibuat mengajukan beberapa aspek mengenai change order serta pengaruhnya terhadap biaya, mutu, dan waktu. Analisis data penelitian dilakukan dengan bantuan program aplikasi SmartPLS 3.0. Pengaruh change order terhadap biaya adalah kurangnya biaya akibat penambahan item pekerjaan, sedangkan terhadap mutu adalah menurunnya kualitas bangunan akibat penambahan volume pekerjaan, dan terhadap waktu adalah terjadinya keterlambatan penyelesaian proyek akibat perubahan pekerjaan yang telah selesai.

Construction practitioners recognise that rework is undesirable due to the detrimental effects. While rework literature has examined rework causation factors in construction projects, the problem continues to plague the industry resulting in poor delivery performance. To better understand this phenomenon and given the scarcity of Malaysian-based rework study, a questionnaire survey involving 130 Malaysian construction practitioners (consultants, contractors and clients) were undertaken to obtain feedback about nature, implications, causes and solutions for rework. Data were analysed using descriptive statistical techniques to prioritise the variables studied. From the analyses, rework is a causal factor for delays and cost overruns, higher wastage and productivity inhibitor. The findings revealed the leading causes of rework are poor quality management, improper planning, lack of communication, design changes and poor subcontractor management. Some practical rework minimisation approaches are also suggested to better manage and prevent rework towards enhanced project performance.
