Although design-build construction projects have recently increased. general conditions of construction contract are not reflecting the characteristic of design-build construction projects neither performing its fundamental roles as implying many claim elements. So. this study aims to propose the basis for improving the general conditions of the domestic design-build construction projects. This study reviews literatures associated with design-build construction contract and analyses domestic general conditions into foreign standard forms of general conditions. Additionally, it is examined the problems of design-build construction contracts and performed questionnaire survey to the practitioner in the construction contract field. In doing so, this study suggests the direction for improving general conditions of domestic design-build construction projects.

Construction uncertainties are frequently exposed to the claims. In most cases, an interpretation of the claims is based on the construction contract. Therefore, the key points of contract negotiation are how to fairly distribute the contract risks to the client and contractor. For these, a FIDIC that is considered as an international standard contract form would be a good reference to decide reasonable contract risk distribution. In order to find out any unreasonable and unfair contract clauses at the general conditions of contract applying generally to public construction project in Korea, this study surveys, analyses and evaluates the general conditions of contract based on a FIDIC, and then proposes a risk mitigation methodology to response those clauses' risk factors reasonably.

The maintenance and repair work of sidewalk block pavement is a construction that requires a large amount of budget to be invested every year. It is important to establish an appropriate standards for estimating construction cost to ensure proper budgeting and quality. In this study, the standards for estimating the cost of maintenance and construction work for sidewalk blocks that can be applied to the construction volume classified according to the site conditions, construction type, and equipment use differentiated from new construction was established. As a result, the daily construction volume was presented by reflecting excavator and truck as equipment in the combination of paver and common worker. The re-installation was applied by separating the construction volume of sections with general blocks and induction/raised blocks based on the installation of sidewalk blocks after demolition. Generally if block cutting is necessary, the precision construction conditions using a cutting machine were taken into consideration to secure the construction quality. In addition, it has been revised to apply classified construction volume into A and B-Type depending on the park and site conditions.

In recent years, the number of female workers pursuing careers in the construction engineering and management field has increased, despite the fact that the job positions have been traditionally considered as retaining job functions and/or qualities that are more appropriate to male than female. This may be attributed to the fact that the positions also require delicate and/or detail-oriented job functions, which can be successfully performed by female. It is important for project participants to understand the working conditions for female field managers by analyzing their job performance. This study collects expert opinions regarding female's managerial performance on job site. Survey questionnaires were administered to two focus groups, male and female field managers who work for general contractors. This study contributes to encouraging female's social and economic involvement by investigating the challenges they face in the workplace, and provides measures to respond to such challenges.

Construction work has character which claim or dispute is frequently raised. This means that each construction project has it's own contract documents due to the difference of environment and time. Therefore to overcome the associated risks, domestic contract rules and acts should be reformed. Several well-recognized contract documents developed by FIDIC, AlA, CMAA and general conditions of the contract is investigated and analyzed. Based on the research outcomes the direction of reformation is suggested.

The construction workers might be at the risk of many occupational injuries and illnesses. To protect workers from various hazards, industrial health and hygiene systems were specified for the construction workers by law. It is important to know the actual health and safety(H&S) conditions by tasks and the characteristics of injuries and illnesses of construction workers. This study was designed to investigate the actual conditions of construction workers exposed to various harmful substances and work elements including evaluation of health status of each worker and general H&S system. Questionnaire was sent to 600 construction workers nationwide and totally 367 people responded to it having 61.67% of response rate. The common construction hazards were dust(29.6%), noise(19.3%), repetitive motions(12.0%), handling excessive heavy materials(11.2%) in order. The repetitive motions and handling heavy materials related to muscle disorders accounted for 23.2%. The accident and injury types were in order of overexertion, falling, overturning, dropping or flying, electric shock, collision, etc.

Many contractors have overlooked the construction contract general conditions and it was a bad construction practice. Today, construction project is very complex and complicated. This requires a networked contract document and results in a complicated contract conflict hardly to be solved. Therefore, to reduce the construction dispute and to enhance construction practice, clarification of definition of Owner, several conditions to be revised, insertion of design supervision were suggested in this paper.

Mountainous areas cover more than 70% of Korea. With the rapid increase in tunnel construction, tunnel-collapse incidents and excessive deformation are occurring more frequently. In addition, longer tunnel structures are being constructed, and geologically weaker ground conditions are increasingly being encountered during the construction process. Tunnels constructed under weak ground conditions exhibit long-term deformation behavior that leads to tunnel instability. This study analyzes the behavior of the bottom region of tunnels under geological conditions of long-term deformation. Long-term deformation causes various types of damage, such as cracks and ridges in the packing part of tunnels, as well as cracks and upheavals in the pavement of tunnels. We observed rapid tunnel over-displacement due to the squeezing of a fault rupture zone after the inflow of a large amount of groundwater. Excessive increments in the support member strength resulted in damage to the support and tunnel bottom. In addition, upward infiltration pressure on the tunnel road was found to cause severe pavement damage. Furthermore, smectite (a highly expandable mineral), chlorite, illite, and hematite, were also observed. Soil samples and rock samples containing clay minerals were found to have greater expansibility than general soil samples. Considering these findings, countermeasures against the deformation of tunnel bottoms are required.

In the absence of any guidance under statutory law, such as the Rules for Construction of Policy, MIA 1906, judges should follow the general principles of interpretation that apply to all contracts. In simple terms, Contra Proferentem Rule means that if the contents of the terms and conditions are ambiguous, they are interpreted against the writer of the terms and conditions. In the Anglo-American Contract Law, the 'default rule' is an important judicial tool that can supplement defects in contract norms and reinforce the principle of private autonomy through gap-filling techniques related to the interpretation of contracts. In Korea, it is sometimes mentioned in case of precedent, and it has been established as a clear rule. This study analyzes the interpretation of terms and conditions is not in the form that the interpretation of other general contracts and other interpretation principles are valid, but contracts based on terms and conditions are also contracts, and as a general rule, the interpretation of terms and conditions is explained like the general contract interpretation.
