I am working on the construction of a small warehouse builing 60' X 40'. The building is a steel framed building with masonry blockwork as the walls. I am looking for the best means to connect the steel frame and masonry blockwork, in particular the steel column masonry block wall connection or...
We are putting together a proposal for the feasibility study and design of a small steel stadium for a soccer field.
Can someone recommend a steel manufacture/ fabricator that we can assist in quoting on the design and supply of the steel elements of such stadium, preferably in the USA...
I am working on a housing development project, as part of the contractor's team. After signing the contract the cost of cement has increased by approximately 25% . The contract states that there will be "no revision in prices". The option we are thinking about is to claim under force majuere...
I am working on an earthworks project and have to come to an agreement with the contractor for the volume of rock (solid boulders) excavated. The contractor has surveyed the rock stock piles using a total station and computed the volume using modeling software. We are reasonable comfortable with...
All,
I am working as a civil engineer in a newly developed consultancy company. I am seeking guidance for purchasing contract documents (form of tenders/ agreements etc.) and specifications for civil and building projects with the intention of the firm representing the clients on these...
I have been asked to advise on settlement problems at a recreation field that was constructed about 3 years ago with a cut/fill operation, the maximum depth of fill being approx 30’. I am uncertain to the compaction achieved whilst carrying out the initial construction of the field, however...
We poured a 8" thk floor slab about a month ago, on the day of the pour the surrounding ground was wet. We poured it using wheel barrows and apparently some clay particles have been left behind in the slab (from the wheels and off the shoes of the labourers).
We noticed pockets of cracking and...
I was asked by owner of a newly constructed building to inspect cracks in the top of a concrete roof. The building was constructed in April this year. The cracks were noticed because after heavy rainfall water would leak through the slab and into the building. The crack widths are about 3mm...
I am working on an earthwork project, which consist of a cut and fill operation. The specification for filling requires a compaction 95% Maximum Dry Density with +/- 2% Optimum moisture content. The geo-technical engineer for the contractor is suggesting using one point proctor method to...
I am working on a project in which concrete cube samples were taken. Tests were carried out at 3,7,28 days, the specified strength was 4000psi. Unfortunately the samples were not placed in a water for curing. After crushing samples at 28 days, the strength were much lower that 4000psi. Can the...
Hi All,
I am trying to put together a contract document for some "minor civil works construction". Does anyone know where i can find some general specifications online?. Typically for excavation, concrete works, formworks etc...
Thanks in advance

Is only anticracking reinforcement specified for these slabs? My problem is a steel building was purchased and the concrete slab and reinforcement were not specified for the metal pan decking. I have no literature on how to design such (one way) slabs . The span is 8 ft so I estimate that...

When extending a building, say a two storey dwelling, should the new members (beams, columns footings)be 1. joined to the existing members by dowelling or exposing rebar splicing new rebar and concreting or 2. not be connected at all, allowed to act as separate structure all together?
Hi,
I would like some advice, I have given the task to design the foundation of a new mechanical workshop in my department. The building will be a steel framed structure. I am responsible for designing the pad footings for the columns and the floor slab.
I have a few questions:
1) Do we need...
I am designing a one storey reinforced concrete frame building (9.15m by 30.39m). Height 4.42 m. Walls on exterior only
Nine frames I set up are at 3.811m intervals, consisting of 2 columns each and 1 beam spanning 9.15m. The loading for interior frames are as follows:
1. seismic 398 kN at roof...
I would like some advice on a project that I am working on. The scope of the project is to design a reinforced concrete retaining wall along a sloping site (slope 24%). I have tried to use the stepped footing approach but it requires excessive excavation. Can I use a footing inclined parallel to...
I am a freelance strutural engineer, i am presently doing alot of analysis for wind and earthquake loadings of reinforced concrete building structures( not usually greater the 4 storeys), retaining walls, and also timber roofs of houses to B.S Codes. This analysis is very repetitive.
Can anyone...
Hi
I have designed a retaining wall to retain soil pressure and over burden pressure from a foundation of a house about 2 meters away. The height of the wall is 4.57m high. My design produced a 330 mm thk wall with T16@125 c/c main reinforcement, vertically ( designed as a cantilever). My...
