下面是building inspection Report的一部分节选。这是一个七年新的duplex。做inspection的时候正好我们在场,那个inspector说如果我们还没签合同就不要签,可是我们已经签了。所以请大家帮忙看看下面这些问题到底有多严重?主要是那个墙上的裂缝和墙面的泡泡。 有朋友说墙面的裂缝只是水泥(render)的裂缝,不是大问题,但如果是地基的问题就麻烦了,怎么看到底是水泥还是地基的裂缝了?
还有如何判断导致墙面的水泡得湿气是从何而来?
另外,如果楼上handbasin水流慢,是大问题吗?
对建筑方面真的是一窍不通 ,所以请高手指教,多谢了
FAULTS
1. Considerable cracking is present in the exterior painted cement rendered walls at various
locations indicating that the builder has not incorporated sufficient techniques in the
construction of this building to prevent cracks from appearing. These techniques may
include, but are not limited to, the omission of vertical articulation joints, the installation of
insufficient articulation joints or the omission of slip joints and although no instability in
the walls could be identified, some risk is present that cracking may increase in extent and
severity in the future.
2. Considerable flaking is present along the surfaces of the exterior painted cement rendered
walls at the front side and rear of the house indicating the builder has not incorporated
sufficient techniques in the construction of the building to prevent damp from occurring.
These techniques may include, but are not limited to, the omission or incorrect installation
of a damp course, the omission, insufficient installation or incorrect installation of weep
holes or the filling of the cavity with rubble.
Extensive patching and painting of the exterior walls is now required to obtain a
satisfactory finish, a repair that will necessitate the complete re-painting of the exterior of
the house with costs being in the order of $15,000 to $20,000 depending on the quality of
workmanship performed. However, some risk is present that further movements of the
walls may occur and further cracking at these locations may appear. Some risk is also
present that flaking along the surface of the walls will also reappear in the future but this is
difficult to predict.
3. Flaking is also present along the cement rendered posts and beams above the first floor
balcony at the front of the house due to damp penetration into the posts and beams and
waterproofing of the posts and beams should now be undertaken with costs being in the
order of $1,800.
4. The internal wall linings in some rooms are cracked due to the slight movements of the
timber wall framing to which the wall linings are attached. This condition is superficial in
nature only and has no structural connotations, however, patching and painting of the cracks
is now required to obtain a satisfactory finish although some risk is present that further
movements of the timberwork will occur and further cracking at these locations or in other
areas may appear but this is difficult to predict.
STRUCTURAL DEFECTS
1. Considerable cracking is present in the exterior painted cement rendered walls and although
no instability has resulted at present, cracking may increase in extent and severity in the
future.
DAMPNESS
Damp penetration into this house may occur at the following locations:
1. Flaking is present along the surface of the exterior walls due to damp penetration into the
walls.
2. Flaking is present along the surfaces of the cement rendered posts and beams above the
front balcony.
3. Buildings on concrete floors are constructed very close to the ground, a condition that can
result in damp entry internally during certain weather conditions.
4. Damp meter readings taken about the surfaces of the internal walls near the floors revealed
no evidence of damp at the time of this inspection. Nevertheless, damp can appear at any
time in the future for various reasons including, but not limited to changes in the weather
pattern, a breakdown of any damp course that may have been installed in the walls, or
concealment of damp by the application of various paints or waterproof membranes to the
walls. Please note carefully that we accept no responsibility for any damp that may appear
at any time in the future. (Photo 3)
5. A box gutters has been installed to collect rain water from a section of the roof. No
evidence overflowing of the box gutter was visible at the time of this inspection but box
gutters are notorious for overflowing and allowing rain water entry through the roof during
certain weather conditions.
6. The exterior walls should be continually treated with a good quality paint or waterproof
membrane to prevent damp penetration through the walls from the exterior.
7. No evidence of water seepage through the balcony floor was visible at the time of this
inspection but if seepage appears, replacement of the tiles and renewal of the waterproof
membrane will be necessary.
