The parameters of heating and cooling of rivets made of steel and aluminum alloy, as well as data of fi lling holes with these rivets during hot and cold riveting are compared. The features of the process of performing cold impact riveting by direct and reverse methods, as well as the possibility of reducing the force of this riveting by improving the closing heads and constructive transformation of the rivets themselves are considered. Features of physiological infl uence of cold shock riveting on hands, elbows and shoulders of workers are determined. Describes the construction of riveting hammers and supports with spring shock absorbers that prevent the disease of workers vibration disease, portable riveting presses of pneumatic and hydraulic action. A description of the press equipment and technology of bolt-riveting connections, allowing mechanizing the process of cold riveting is given.

AbstractThe paper presents methods of determining the location of cost buffers and corresponding contingency costs in the CPM schedule based on its work breakdown structure. Application of correctly located cost buffers with appropriately established reserve costs is justified by the common overrunning of scheduled costs in construction projects. Interpolated cost buffers (CB) as separate tasks have been combined with relevant summary tasks by the start–to–start (SS) relationship, whereas the time of their execution has been dynamically connected with the time of accomplishment of particular summary tasks using the “paste connection” option. Besides cost buffers linked with the group of tasks assigned to summary tasks, a definition of the cost buffer for the entire project (PCB) has been proposed, i.e. as one initial task of the entire project. Contingency costs corresponding to these buffers, depending on the data that the planner has at his disposal, can be determined using different methods, but always depend on the costs of all tasks protected by each buffer. The paper presents an exemplary schedule for a facility and the method of determining locations and cost for buffers CB and PCB, as well as their influence on the course of the curve illustrating the budgeted cost of work scheduled (BCWS). The proposed solution has been adjusted and presented with consideration of the possibilities created by the scheduling software MS Project, though its general assumptions may be implemented with application of other similar specialist tools.

The development of green buildings has become a global issue as global climate change is gradually becoming a serious concern for the future. Government buildings can be categorized as buildings that must comply with green building requirements, because they consume energy, water and other resources with large quantities. The absence of guidelines in maintenance and repair of government buildings will have an impact on the security and comfort of building users. In addition, the absence of guidance regarding the material specifications used will also result in a material stock system for maintenance and repair being ineffective. This study discusses the development of implementation guidelines for maintenance, reparation and determine material specifications for mechanical components design in government own green buildings based on work breakdown structure. This research will detail starting from the sub work section, work package, alternative design, implementation requirements, activities, resources and material specifications. With the implementation guidelines for maintenance, reparation and determine material specifications for mechanical components design in government own green buildings based on work breakdown structure (WBS) expected maintenance and reparation of government buildings can be implemented maximally, according to specifications and functions.

WBS (Work Breakdown Structure) plays an important role in every construction project. WBS is a hierarchy of decreasing scope of work to become the smallest level called a work package, making it easier in the process of project management and control. The current problem is that many contractors in Indonesia, both large and small contractors, do not understand the importance of using WBS in a construction project. This causes project performance to be less than optimal, especially on cost and time performance. Currently, WBS standards have been developed for building projects. In this study will look at the cost and time performance of the project from the use of WBS standard building. The sample used in this study are projects that have applied the use of project standards. The projects include Building X, Lecture Building Y, and Sports Facility Building Z. The method used in this study is the EVM (Earn Value Method) approach, collecting data using questionnaires. The results showed that using the WBS standard had an effect on cost and time performance. Good cost and time performance is shown in the Building X and Lecture Y buildings. While the cost and time performance of the Z Sports Facility Building tends to be unstable. This is because the work items that exist in the WBS standard are not in accordance with the project conditions, so it is necessary to adjust work items.
