A review of the operation of the GCCC Contracts on Civil Engineering projects
This document outlines the tender process for the construction of a 4-story commercial building. It includes 9 sections covering instructions, conditions, forms, specifications and drawings. Requirements include experience with similar projects of at least 1.2 crore BDT, an annual turnover of 1 crore BDT, and liquid assets of 80 lacs BDT. The tender submission deadline is November 12th, 2015. The opening will be on November 17th at the Executive Engineer's office. The performance security required is 10% of the contract price. The intended completion date for the project is November 5th, 2017.
The document is the tender and contract conditions for the construction of a building in Liwan, Dubai. It includes instructions to tenderers on submitting the tender, requirements for site visits, and clarification of contract documents. The tender must include supporting documents such as proof of a site visit and a tender bond. The employer reserves the right to accept or reject any part of the tender. The tenderer is responsible for understanding all project requirements and conditions. No changes can be made to the tender documents except for filling in blanks.
The document discusses the procedure and essential elements involved in preparing a final account. It defines key terms like final account, provisional sums, and prime cost sums. The procedure for final account involves the contractor submitting documents within 6 months of completion for the architect to complete the account within another 6 months. Adjustments must be made for variations, remeasuring provisional quantities, omitting unused provisional/prime cost sums, and adding back nominated subcontractors' accounts. Implications of omitting works from the bill of quantities and not allowing them as provisional sums are discussed from the client and contractor perspectives.
Knowing the need of utilising the energy sources efficiently, people are utilising the solar power resources. The inforgraphy states four different types of solar power. Reading them thoroughly will give you an idea which will suit best to your requirement.
This research poster was created as a part of the 2014 Solar Symposium and is by James Mueller and Amit Ronen.
Fitting Clean Energy into a Reformed Tax Code” Given the looming expiration of clean energy tax incentives and the likelihood of comprehensive tax reform, the clean energy sector need to be developing pragmatic and politically attuned alternatives that fit within the context of tax reform principles. The GW Solar Institute is launching a research series, Fitting Clean Energy into a Reformed Tax Code, which seeks to develop innovative policy solutions and inform policymakers on the full range of impacts that these potential options could have.

This document lists potential 30-year savings from installing solar photovoltaic systems on the roofs of 50 large school districts in the US at installed costs of $2/watt and $2.50/watt. It shows that New York City public schools could save $209-169 million over 30 years, with savings per student of $270-218. Los Angeles public schools could save $91-61 million, with savings per student of $145-96. The largest savings per student were for Hawaii Department of Education at $380-329. Overall, significant savings were projected for many large school districts across the US from installing solar panels on their roofs.
The document provides solar industry employment data for various US states in 2013. It lists the number of solar jobs, top solar subsectors by employment, and rankings for each state on metrics like solar jobs, solar jobs per capita, solar companies, electricity prices, solar capacity and policy factors. For example, it shows that California had the most solar jobs (47,223), while Alabama had 420 solar jobs and Hawaii had 2,600 solar jobs mainly in installation, sales and distribution. It also provides sources for more detailed state solar policy and market information.
This document summarizes key facts about solar energy in the United States and Florida: [1] The U.S. consumes disproportionately more energy than other nations; [2] Solar power can be implemented across the continental U.S.; [3] Solar industries have grown rapidly in recent years but face political threats; [4] Florida ranks among top states for installed solar capacity and jobs but still has opportunities for growth compared to other leading states.

Softer Solar Landings: Options to Avoid the Investment Tax Credit CliffGW Solar Institute
This document analyzes the potential impacts of allowing the 30% federal investment tax credit (ITC) for solar energy to expire at the end of 2016 as scheduled under current law. It finds that failure to extend the ITC could result in a 10% or greater increase in the cost of solar energy from 2016 to 2017, along with 42% fewer utility-scale solar installations and 15% fewer distributed solar installations in 2017. It considers several policy options Congress could pursue to mitigate these impacts, recommending a two-year extension of the current ITC levels followed by a gradual phase-out as solar and other technologies reach full market maturity and scale.

GRID CONNECT SOLAR POWER GENERATING SYSTEM
I DEFINITION
The Grid Connect Solar Power Generating System consists of mainly three components viz. the solar photovoltaic (SPV) array, module mounting
structure and the power conditioning unit (PCU)/ inverter. The SPV array converts the solar energy into DC electrical energy. The module
mounting structure holds the modules in required position and the DC electrical energy is converted to AC power by the PCU, which is
connected to the power grid. The AC power output of the inverter is fed to the AC distribution board through metering panel and isolation
panel. The 415 V AC output-3Ø of the system can be utilized or as an option it could be stepped up to the required voltage level and after
synchronizing with the grid, can be exported to the grid.
