One of the BCIS informations – Merthyr Tydfil Mid Glamorgan, Merthyr Tydfil is banned in this study for analysis and comparing due to the undermentioned ground:

I. The cost per mA? is excessively high comparing to others undertaking and the location factor is merely 0.98.

two. Many component cost is undefined in inside informations, illustration floor coatings, wall coatings, ceiling coatings, internal and external doors, roof, etc.

three. The preliminary is merely 14.52 % of the contract amount ( excepting eventualities ) compare to others 5 undertakings. Therefore, this elemental cost is non analytical.

Price & A ; Design Risk is assumed as 7.0 % and eventualities assumed as 2.5 % for the two proposed undertaking.

4.1 Element cost accommodation

The rational accommodation for component cost as below:

I. 2A Frame – Proposed steel column and beam frame for this edifice. This component is cost 5.36 % of the undertaking and 2.30 % lower if comparison with Merthyr Tydfil undertaking.

two. 2C Roof – Proposed steel pitched roof with individual ply waterproofing membrane for this edifice. This component is cost 4.43 % of the undertaking and 1.44 % lower if comparison with Merthyr Tydfil undertaking.

three. 2G Internal Wall / Partitions – Proposed metal he-man and cell dividers is because a board room and two meeting room are required by client.

four. 2H Electrical Installation – The per centum distribute to this component is 12.43 % and is the highest comparison to other five undertakings. Therefore, we proposed to cut down the utilizations of electricity to this edifice by 5.97 % .

4.2 Cost analysis program for metropolis Centre – Edinburgh City, Scotland

Refer to the above BCIS informations, location factor above 1.00 is Aylesbury, Buckinghamshire, Aylesbury Vale, Oxford Oxfordshire, Oxford and Uxbridge, Greater London, London Borough of Hillingdon.

Harmonizing to the current cost index of 212 ( 1Q2010 ) for the Proposed 3 Storey New Office Block at Edinburgh City and location factor is 1.09. The updated cost per mA? for Aylesbury, Buckinghamshire, Aylesbury Vale is ? 1,561.69, Oxford Oxfordshire, Oxford and Uxbridge is ? 1,341.77, Greater London, London Borough of Hillingdon is ? 1,296.19.

Oxford Oxfordshire, Oxford and Uxbridge and Greater London, London Borough of Hillingdon is non selected because the updated cost per mA? is lower than Aylesbury, Buckinghamshire, Aylesbury Vale. The low monetary value for these two countries may be due to the location that nearby the border of the metropolis and it is unable to accomplish a high category office edifice.

However, the updated cost per mA? of ? 1,561.69 for Aylesbury, Buckinghamshire, Aylesbury Vale is selected for budgeting intent merely and this is current cost and non includes building rising prices and involvement rates.

The current cost bound is ? 2,322,729 and the projected stamp sum is ? 2,300,817 as apply ? 1,401.38 as current cost per mA? in analysis 3.

5.0 SUSTAINABILITY OF Building

Building proprietors, interior decorators and builders face a alone challenge to run into demands for new and renovated installations that are accessible, secure, healthy, and productive while minimising their impact on the environment. The chief aims of sustainable design are to avoid resource depletion of energy, H2O, and natural stuffs ; prevent environmental debasement caused by installations and substructure throughout their life rhythm ; and make reinforced environments that are liveable, comfy, safe, and productive.

In UK, Green Building, besides known as green building or sustainable edifice, is the pattern of making constructions and utilizing procedures that are environmentally responsible and resource-efficient throughout a edifice ‘s life-cycle: from sitting to plan, building, operation, care, redevelopment, and deconstruction.

5.1 Reduce Carbon Dioxide Emission

In UK, one-year CO2 emanation is 568,520 in 1000s of metric dozenss. Buildings are responsible for more than 70 per centum of electricity usage ; hence, cut downing electricity usage in edifices straight affects C emanations in electricity production.

Therefore, solar panels and heat exchange system are proposed in this undertaking for infinite warming and air-conditioning.

5.2 Whole life cost of the edifice

Solar energy is renewable and basically free. There are two factors that influence the sum of money solar panels will salvage you on your electricity measures: 1 ) the sum of money you spend on your current electric measure, and 2 ) the sum of electricity your solar panels will be supplying.

The demands of solar energy acquire good known because of the high monetary values for electricity measure utilizing conventional beginning. The worldwide of demand for solar energy is greater than its supply. This is due to it will cut energy ingestion and pollution beginnings like they have lower heat loss, less air escapes, warmed window surface that better comfort and minimise condensation.

Automatic lighting and air conditioning control system is proposed, illustration it will automatic off and / or alteration to some low electromotive force lighting after working hr.

6.0 COST SAVINGS PROPOSAL

The cost program is for appraisal budgeting merely but non concluding contract amount for this undertaking, so to command the concluding cost within budget and / or addition extra net income from the economy, the following cost nest eggs for this undertaking are proposed:

I. Proposed Slimdek extends the scope of cost-efficient steel options for modern edifices. Ease of planning and service, combined with a decrease in edifice tallness, gives important cost and velocity of building benefits. Slimdek is particularly economical for extremely serviced edifices. Flexibility of routing services without restraint and the ability to suit services between the ribs can take to significant nest eggs in the cost of services.

two. Proposed to get down work at month April 10 ‘ because the frame work and roof covering able to complete when winter season, this aid to salvage extra cost when concept in winter season, examples heating for bring arounding concrete, protection of new work ( concrete and brickwork ) , etc. This assist contractor to salvage extra cost and will reflect to overall development cost for client.

three. Solar warming panels is a the use of solar energy to supply procedure that depends on the solar radiation, surface country, surface coefficient of reflection, surface emissivity, ambient temperature, and thermic convection from air current.

7.0 ADDITIONAL INFORMATION TO ACHIEVE A FIRM PRICE

We required extra information which will hold impact on costs in order to fix a firmer appraisal cost as below:

I. Ground status

two. Site topography

three. Site bing construction, handiness and protection

four Market status

v. Type of contract for the undertaking

8.0 CONCLUSION / RECOMMENDATIONS

The quality of the edifice is more of import for offices than for other development like retail. It should supply necessary services and enable flexible sub-division of floor infinite. While location ( reference ) is of import, congestion is cut downing efficiency and promoting out of town office Parkss.

Therefore, Proposed 3 storey office block at Aberdeen City, Grampian alternatively of Edinburgh City due to the undermentioned grounds:

I. Based on the comparing, the cost is excessively high physique at metropolis Centre, i.e. ? 274,398 or 13.54 % higher instead use the money for upgrade the edifice quality.

two. Office edifice is promoting to construct at outskirts of metropolis due to the congestion is cut downing efficiency and the quality of office edifice is more of import than location.

three. The land value at Edinburgh City is more expensive comparison with Aberdeen City, Grampian. This 3 floor little office ca n’t to the full use the land value at Edinburgh City.

four. harmonizing to CB Richard Ellis, Market View Scottish Office H1 2008, completion of office at Edinburgh City are set extremum in 2009 when 611,400 sq foot ( 56,799 sq m ) is anticipated to be delivered mean the market of office development at Edinburgh City is competitory.
