There are many definitions of project management. This post try to pisk out some most common that widely accepted and understood. Also listed here the job description and main activities that project management job must cover.

Definitions of Project Management:
* PMBOK (Project Management — Body of Knowledge as defined by the Project Management Institute — PMI):“Project management is the application of knowledge, skills, tools and techniques to project activities to meet project requirements.“

Construction insurance provides safeguards for you as an employer against your construction workers being injured on site. Construction insurance does not exempt you from maintain a safe workplace. Usually, construction insurance policies only pay out if a strict set of health and safety guidelines are followed.

Construction insurance is an important policy to have if you own, run or manage a construction site.

Construction insurance provides safeguards for you as an employer against your construction workers being injured on site. Construction insurance does not exempt you from maintain a safe workplace. Usually, construction insurance policies only pay out if a strict set of health and safety guidelines are followed.
Construction insurance also covers materials and machinery on the construction site in the event of an accident, fire or theft. Due to the high cost of building materials in the current economic climate, the theft of building materials is getting more commonplace and gives a good reason why you should opt for construction insurance.

 Construction Bids are written offers from contractors to undertake a construction job in return of a certain sum of money.

What is Construction Bids?

Construction Bids are written offers from contractors to undertake a construction job in return of a certain sum of money. Bids can be either Negotiated Bid, Limited Competition, Selective Bid or Open Competition Bid. This article will talk about Negotiated Bid while the other will be written in fupcoming posts.

Negotiation Bid

In this method the price to be paid in return of the work to be done is negotiated with a single contractor. This , obviously, does not provide the owner with a comparative prices. Though the cost of a work will be higher in this method, an owner may expect some advantages from employing a particular contractor whose policies and methods are known and who has in the past proved capable of fulfilling his obligations. The higher cost may be offset by better quality , early completion, and smooth administration.
The negotiated construction bid procedure can be adopted to the owner’s advantage if the chosen contractor is one in which the Owner and the Engineer have confidence, and which is of known integrity and reliability. Moreover, the work to be carried out is within his special scope and experience.

Criteria for Buildings

The AISC specification for ASD for buildings places a limit on compressive stress in webs to prevent local web yielding. For a rolled beam, bearing stiffeners are required at a concentrated load if the stress f a , ksi (MPa), at the toe of the web fillet exceeds F a = 0.66F y w , where F y w is the minimum specified yield stress of the web steel, ksi (MPa). In the calculation of the stressed area, the load may be assumed distributed over the distance indicated in Fig. 9.4.

Horizontal deflections in the planes of bents and shear walls can be computed on the assumption that they act as cantilevers. Deflections of braced bents can be calculated by the dummy-unit-load method or a matrix method. Deflections of rigid frames can be computed by adding the drifts of the stories, as determined by moment distribution or a matrix method.

For a shear wall (Fig) the deflection in its plane induced by a load in its plane is the sum of the flexural

Figure showing Building frame resists lateral forces with (a) wind bents or (g) shear walls or a combination of the two. Bents may be braced in any of several ways, including (b) X bracing, (c) K bracing, (d) inverted V bracing, (e) knee bracing, and (f) rigid connections.

 The countdown to the Eurocodes changeover has begun. So we ask – how prepared are you?
Are you are a structural engineer and unaware of what Eurocodes are by now? If so, it is unlikely that you will have been working at the hard end of design. The clock is ticking and there is now only a year left until compulsory implementation of Eurocodes on public projects. If designers fail to get up to speed soon, they could well end up left on the shelf when it comes to winning work.

Eurocodes are causing the biggest shake-up in engineering since the UK went metric. They are a set of new building codes that will replace British Standards by March 2010. These codes are supported by national annexes which give country specific values and published documents (PDs) that contain guidance included in BritishStandards but not in Eurocodes. The full set of Eurocodes is now published, as are the majority of annexes.
“For engineers working on public projects, it seems there will be little choice but to use the Eurocode on projects procured after March 2010 under the requirements of the [European Union] Public Procurement Directive,” says Parsons Brinckerhoff (PB) director of bridge and structural engineering Steve Denton. “There has been a huge effort to finalise the UK National Annexes and provide other supporting information such as PDs and companion BSI British Standards Published Documents.
