Assignment Brief

Scenario
You have recently been employed as a civil engineering technician. Your employer, a medium-sized general contractor, has been commissioned to design and build a small building in a local industrial park. The design team within the company has prepared a set of outline design drawings, which provide general information about the proposed building, site and form.

You are tasked with the responsibility of preparing the construction information package that will allow the construction team to build the project. The package of information required includes the following:
• Site Location Plan
• Site plan
• Floor plan
• Elevations
• Section/Details
• Door and window schedules
• Outline bill of quantities
• Schedule of works

Accompanying the construction information package, your employer wishes to understand your reasons for the drawings, specification and schedules that you have produced.
The submission is comprised of two parts:
1. Construction Infrmation; to include:
a) Site Location Plan (1:1250)
b) Site plan (1:500 or 1:1000)
c) Floor plan (1:50 or 1:100)
d) Elevations (1:50 or 1:100)
e) Section (1:20)
f) Detail(s) (1:5)
g) Door and window schedules
h) Outline bill of quantities
i) Schedule of works

All drawings are to be on a minimum sheet size of A3. They should include a title block, showing project information and be numbered using an industry standard.

Drawings should be produced using an industry standard CAD software package. BIM software may be used but is not required.

2. A written report - this should be a justification of your decisions for producing specific information for the project and compare the choices you have made with other potential information types.

LO 3: Interpret different types of construction information in order to explain a construction project.
LO 4: Assess ways in which construction professionals collaborate in the production of construction information.

Scenario
One of your colleagues, in a medium-sized general contracting firm, has produced a set of construction information documents for a small industrial building. Before issuing this information to the construction team, your employer has asked that you review the information to ensure that it is fit-for-purpose. In particular, your employer asks you to:

• coordinate the drawings with the schedules, specifications and bill of quantities
• identify any information clashes
• highlight areas where there may be missing, or incorrect information provided.

You are then tasked with making corrections to the construction information, ensuring that copies of the originals and your recommended changes are recorded.

Finally, you are asked to prepare a short report on the construction information package that you have reviewed. You will discuss your findings with the original author of this work, as part of both of your continuing professional development.

The submission is comprised of two parts:

1. Construction Information Review; to include:
a. ‘Redlined' construction drawings (highlighting errors or inaccuracies)
b. ‘Marked-up' specifications and schedules (highlighting errors or inaccuracies)
c. Corrected versions of all documentation, with suitable revisions recorded.

2. Feedback Report - Produce a report explaining the design team roles (such as Architect, Landscape Architect, Quantity Surveyor, Civil Engineer, Building Services Engineer etc), how they work with each other and assessing the types of information produced by each. The report should also highlight and compare the impact of CAD and BIM in the collaborative process of producing construction information.
