SECTION A

Marks1. A new six-storey framed building with a 4 metre deep basement, is to be

constructed on a city centre site which is close to a river.

(a) Identify four aspects of the ground investigation report which wouldbe of interest to the engineer in the design of the foundations for thebuilding.

Description of each stratumDepth and level of change of each stratumLocation of samples, disturbed and undisturbedLocation and results of field tests: eg penetration tests, vane test etcResults of laboratory tests: eg chemical analysis (sulphates), pH value etcWater levels and a record of each water strike

Any 4 from the above, 1 mark each. 4

(b) Study the borehole log shown in Figure Q1(b). Describe, with theaid of annotated sketches, an appropriate ground water controlsystem which may be adopted by the contractor during theexcavation and the construction of the basement. Give reasons foryour choice of system.

Wellpoint system with suction pumps.

This is because water is present at 2.5m and the depth of the basement is4.0m, and therefore the water level requires to be lowered duringconstruction of the basement. The wellpoint system is known to be ideal innon-cohesive soils such as sandy gravels shown on the borehole log.

The wellpoint system consists of a number of small diameter vertical wells(normally disposable) connected to a header pipe which is under vacuumfrom a pump. The ground water is forced out of the soil by atmosphericpressure into the header pipe, via the wellpoints, and discharged by thepump.

4. (a) (i) Briefly explain why the house shown in Figure Q4(a)(i) may besaid to have correct visual scale.

The candidate’s answer should cover the substance of the following:

A house should not be intimidating to normal users, so the scaleshould be related to an average human.The figure shows human forms beside the house at a size to suit thedoor, steps etc. This gives the building correct visual scaleprovided the human forms are in the same plane as the building. 1

(ii) What makes the group of buildings shown in Figure Q4(a)(ii) appear to be out of proportion?

The group shows a tall tower block beside lower buildings.The tower block seems to be crushed by the lower buildings and thelower buildings seem to be dominated by the tower block. 2

(iii) Illustrate graphically, the difference between scale and proportion.

This building shows all the elements, doors, windows and over-allshape to be reasonably in proportion and the scale would normallybe assumed to be domestic. However the inclusion of the figure infront shows that the building is much larger scale than domestic andmay indicate a much larger building.

Other examples are acceptable. 2

Marks

[C021/SQP155] 34 Page eight

(b)(i) Briefly explain what is meant by each of the following terms as usedin architectural design:

(1) form;(2) function;(3) mass.

Form is the structural system used e.g. framed, load bearing wall,cross wall, space frame etc. 1Function is what the building will be used for expressed in thedesign e.g. school, offices, flats, church etc. 1Mass is the relationship between the design and the apparent 'weight'of the building. This is related to the size or volume of the buildingand can be offset by use of openings, windows or different finishes. 1

(ii) Produce a sketch to show the relationship between form, function andmass as used in architectural design.

The sketch shows an aircraft hanger beside a domestic scale building.The hanger is massive beside the smaller building and the shape of thehanger expresses the structural form from which it was created andalso the functional requirement of large uninterrupted space internally.

Any other suitable example will be acceptable. 2 (10)

5. (a) Identify four items of spatial information which would be collectedduring a measured survey of an existing building.

Any four items will be acceptable, such as:

(i) social factors;(ii) functional factors;(iii) technical factors.

The candidate’s answer must cover one relevant factor in each category.Acceptable factors are as follows:

(i) Social factors could include the special memories a church mighthave for those of the public married or baptised etc in the church.The objectors would have to be appeased in some way. 1

(ii) Functional factors could include the shape of the existing building,the floor to floor/ceiling heights, the position of openings etc. 1

(iii) Technical factors could include the cost to upgrade the fabric tocurrent standards e.g. thermal insulation, damp proofing, requirementfor new opening may not be allowed etc. 1

(c) The walls of the church building are constructed of 600mm thicksandstone and the internal lath and plaster finish will require to beremoved. Explain, with the aid of an annotated sketch, how a suitablereplacement finish, providing better thermal insulation, could beprovided.

One solution would be to strap the walls and add insulation betweenthe straps, with all necessary vapour protection.External insulation would not be acceptable as the outside appearancewould be altered.

6. (a) Explain what is meant by the following terms relating to foundationdesign:

(i) settlement;(ii) subsidence.

(i) Settlement is downward movement brought about by thepressure from a foundation causing compression of the ground. Itis the differential settlement of one part of a building relative toanother that produces distortion and cracking. 2

(ii) Subsidence is the sudden downward movement of the groundbrought about by an activity in the ground such as mining, soilerosion, removal of water from the ground (particularly in claysoils), compression of loose or man-made fill etc. 2

(b) An extract from a surveyor’s field notes is shown in Figure Q6(b). Thisprovides details of cracking on the elevation of a building. Describepossible causes for the cracks in each of the locations indicated.

Diagonal cracksSubsidence caused by:Mining below groundSoil erosionFrost heaveShrinkage of clay soil caused by removal of water either by trees orprolonged hot weather.Man-made fill at that corner of the building. Any three for 3 marks 3

7. A small office development is to be constructed on a city centre siteadjacent to existing buildings. The site is over a deep bed of sandygravel.

Marks

(a) Explain the following terms as they relate to types of pilefoundations:

(i) replacement pile;(ii) displacement pile.

(i) A replacement pile is constructed by removing ground(normally by boring) and replacing it with reinforcedconcrete or grout. 1

(ii) A displacement pile is constructed by displacing theground laterally by driving in a preformed pile or tube. 1

(b) (i) Select a suitable type and system of pile for the project,giving reasons for your choice.

Continuous flight auger (CFA)Displacement pile such as driven precast or driven cast-in-place piles should not be used near existing buildingsas the displacement may disturb the adjacentfoundations. Vibrations may be a problem together withnoise polution from driving. CFA is a replacement pilewhich is relatively quiet and will not disturb adjacentfoundations. These piles are also suitable in a widevariety of soils 2

8. A new prestige high-rise city centre office development is to be constructedusing a steel frame.

Marks

(a) Discuss the performance standards that would need to be satisfiedin the design and specification of the flooring element of the project. Provide a level surface with sufficient strength to support the

dead and imposed loads as set down in current standards. Provide compartmentation and fire resistance between offices

on different floors to comply with current standards. Provide a level surface to receive the chosen finish. Provide resistance to the passage of sound between floors. 4

(b)(i) Select an appropriate system of floor construction for the buildingand clearly justify your selection.

Composite floor comprising a profiled metal deck and in-situreinforced concrete. This floor system uses the profiled metal deckas permanent formwork for an in-situ concrete slab and hencespeeds up construction work. The metal deck also acts as bottomreinforcement to the slab. Good sound insulation and fire resistanceis also achieved. 2

(ii) Worksheet Q8 shows an incomplete section through the steel frame.

Using the worksheet, complete the drawing to an approximate scaleto show the construction of the floor and ceiling, including finishesfor a typical office. Include notes to ensure compliance with currentstandards.
