The literature review is aimed at covering the study of the research related to labor productivity calculations performed to evaluate the performance of the United States construction industry and the development of formulae used to perform the labor productivity calculations.
Attempts at the quantification of labor productivity of the construction industry
Considering the magnitude of construction industry, any research is not only critical in improving the nation’s economy but it will also assist in improving the productivity of construction work force (Chapman and Butry, 2008). But studies related to the accurate measurement of the productivity of the construction industry has been limited (BFC, 2006). Many researchers have made efforts in identifying the factors, which drive the construction labor productivity, and in developing robust methods for its measurement. According to one of the first studies conducted in terms of analyzing labor productivity of the construction industry, from 1968 to 1978 the productivity of the construction industry has experienced a decline because of delayed growth in capital per worker (Stokes, 1981). Another study supported this finding that construction industry has declined from 1968 to 1978 and regarded the shift in the output between commercial projects to residential projects as the contributing factor (Allen, 1985). Another attempt at measuring labor productivity found that the productivity has increased from 1980 to 1990 due to depressed real wages and technological advances (Allmon et al. 2000). In 2004, a study suggested that although construction industry has significantly adopted the technological advances, the productivity of the industry experienced a downfall from 1964 to 1999 ...

...t the sub-sector level rather than at the industry level since the aggregation of data at the overall industry level may camouflage productivity trends at the individual sub-sectors (Rojas and Aramvareekul, 2003)
Relevance to the study:
Like the previous study, this research also had a broader approach in calculating the labor productivity. This study attempted to estimate the labor productivity of the entire industry by taking weighted average of the grouped sectors. Consequently, it was recommended that the measurement of labor productivity be examined at the sub-sector level rather than at the industry level since the aggregation of data at the overall industry level may camouflage productivity trends at the individual sub-sectors (Rojas and Aramvareekul, 2003).
Table 1 shows the comparison of the two previous studies and the development of the proposal.
When we see an economic downturn many of the different industries are affected in different ways depending upon their demand. The industry which always seems to be affected first and the last to recover is the construction industry. The construction industry is one of the largest sectors of the UK’s economy. It contributes around £90billion which is 6.7% of the total and 2.9 million people are employed within the construction sector. (HM Government, 2013) (Barawas and Fleetwood et al., 2013) This contribution is measured by the Gross Value Added (GVA), here below is a table to represent the contribution the construction industries GVA (for 2012 prices) and its % of economy.
The construction industry plays an important role in competitiveness and prosperity of the economy in terms of its significantly contributing to shelter, infrastructure and employment (Anaman and Osei-Amponsah, 2007). A number of researchers have investigated on the vital role of the construction sector to the overall economic growth. In Rhodes’ paper who stated the construction industry in the UK contributed £83.0 billion in economic output in 2012, which accounts for 6% of the total. Also, workforce jobs in the construction industry in UK were 2.03 million in 2012 and 2.12 million in 2013, account 6.4% and 6.5% in total respectively (C. Rhodes, 2013). Oladinrin indicated the significance of construction linkage with the aggregate economy in Nigeria by studying on construction output and Gross Domestic Project (Oladinrin and etc., 2012). A recent report of U.S. Bureau of Economic Analysis showed that the GDP value added of construction industry was $652,723 million in 2014, 3.7% of total GDP (http://www.bea.gov/industry/gdpbyind_data.htm). Besides, a report of U.S. Bureau of Labor Statistics stated the employment by construction industry sector take 4.7%, 3.9% and 4.5% in the year of 2002, 2012 and 2022 respectively (http://www.bls.gov/emp/ep_table_201.htm). The construction industry has been playing an influential role on domestic GDP in China (Zhou and Liu, 2007). A report of National Bureau of Statistics of China
In order to determine if total factor productivity is an accurate measure it is important to look at another economist that utilizes a different empirical method. Antras and Voth (2003) explore the slow growth of total factor productivity between 1750-1850 in Britain (p.53). This is similar to Craft (2004a) and Craft (2004b) since they found during this time that there is slow total factor productivity. However, there is a disadvantage in the time period that they focus on. Similar to Craft (2004a), they look at the time period where the steam engine did not have the greatest impact on total factor productivity. However, the research will still give a broad overview of its impact and may suggest that the steam engine had a higher impact than Craft (2004a) found. Unlike Craft (2004a) and Craft (2004b), Antras and Voth utilize a dual method in order to discover independent estimates of TFP growth during the British Industrial Revolution (p. 55). Their dual method is based on looking at factor prices. They decide to look at factor of production prices since they will tend to rise when productivity increases (p. 57). A downside to their experiment is that they make a couple of assumptions. The assumption that they make in order to be able to use their equation is that there was perfect competition and constant returns to scale (p.57). It is
Construction industries are classified largely which comprise of skillful employee and general workers. As opined by Cassidy (2006), these are intrinsically demanding, hazar...
In many nations, the relationship between labor and production has often been a tense one. On one side of the equation, businesses have insisted on greater productivity at lower costs. On the other side, labor (most often in the form of labor unions) has insisted that increased productivity can be best be achieved if the workers have a reasonable “living” wage and job security (Howard 2002).
Growth in labour productivity is important because it is associated with economic growth, standards of living, and real incomes. It is another useful tool that we can use to compare the welfare and growth of countries. Labour productivity measures the amount of Real GDP produced by an hour of labour. Increases in labour productivity can occur from increases in the amount of machines and equipment available to workers, a higher proportion of skilled workers, increases in plant scale, changes in organizational structure, and improvements in technology (1).
Productivity in the United States, due to new innovations (that are coming together after years of investment), is growing to levels not seen since the 1960’s. For example: productivity growth has averaged 2.3 percent from 1996 to 1999, doubling the 1.1 percent average productivity growth from 1973 to 1995. At a rate of two percent from 1996 to 1999, labor has also increased, as unemployment fell and welfare recipients have gone to work. The economy has been growing at a rate of about 4.5 percent each year, due to this.
The Construction industry in the US has faced some interesting changes throughout its progression. From economic instability during the housing market crash to amazing technological advances to reduce the need for construction workers and therefore the cost associated with newly built properties in the real estate market. Beginning with the first tools ancient man used to carve their niche in the soon to be global expansion of arguably one of the oldest trades in history, construction has a rich history of trial and error, analysis and engineering that covers a very necessary skill that directly affects everyone who seeks and finds shelter, a place to work or any aspect of public works and many
The main important role of the Project Management in the construction industry is to make everyone work towards the same goal that must be aligned with the strategic objectives of the company. One of the most relevant differences between any Project Management and the ones working on the Construction industry is the knowledge and skill in certain areas related to the field, it is essential to have a good understanding of construction methods, materials, scheduling and blueprint reading as well as knowledge in communication and leadership skills. In construction technology plays an important aspect to considered, for a Project Management it is important to be updated in any new technology used by construction companies. (Dykstra, 2011)
"...the productivity performance of the manufacturing sector of the United States economy since 1995 has been abysmal rather than admirable. Not only has productivity growth in non-durable manufacturing decelerated in 1995-9 compared to 1972-95, but productivity growth in durable manufacturing stripped of computers has decelerated even more."
Brooke (1997), explains Estimation as the technical procedure of anticipating the value of the project. Building construction estimation is the process of acquiring the construction value for the whole project before the project starts. Thus, construction attaining process depends hugely on financial management to sustain workability and smooth operations. The delay in construction is a global issue which is due to improper preparation of estimates and lack of drawings (Ajanlekoko, 1987). In accordance to Gkritza (2008), the source of delay in a project are identified to be in the initial stages, like bad quantification, errors in design and ground conditions. Thus, the purpose of a proper estimate is to foretell the cost needed to finish the
India is serving piping hot construction projects all across the country. With India’s economy getting bigger and bigger. A new study by Global construction perspectives and Oxford Economics says, India will become the world's third largest construction market by 2025, adding 11.5 million homes a year to become a $1 trillion a year market. Infrastructure industry led by some of the established as well emerging companies have constituted a strong domestic market and has displayed a sturdy performance with continuous growth.

This paper explores what it takes to be a construction manager and the responsibilities of being a construction manager and the skills that a construction manager should have. It also explores what good construction managers do to have success on their construction projects and the steps that a construction manager must follow to end a project and meet their deadlines at the same
While there is no disagreement on this general notion, a look at the productivity literature and its various applications reveals very quickly that there is neither a unique purpose for, nor a single measure of, productivity. But many different productivity measures are available but choice to apply which depends on the purpose of productivity measurement and in many times on the available of data. Productivity measure in general can be categorised as either single factor productivity or multifactor productivity measure depends on the measure of output to input (OECD 2001). An economy only increases if the people “works smarter” and acquire more output from a given supply of
