Task 1: Construction methods and work preparation

You work for a construction company and support the work preparation for the construc-

tion of a 1,000-meter-long reinforced concrete canal. Your tasks include earthworks,

sealing works and the construction of the reinforced concrete structure (ref. Figure 1-

for top view and Figure 1-2 for vertical section).

c) Work estimate (30 min.)

You are at the time of the beginning of the construction works. For the controlling

of the construction project, a comprehensible work estimation has to be estab-

lished under consideration of the given boundary conditions. It was decided to

subcontract the reinforcement works for the canal bottom slab and the canal walls.

Use annex 1-3 to prepare the work estimation. In addition, calculate the contribu-

tion margin, the construction site result and the contract amount.

Quantities earthworks (rounded):

Excavation works = 32,000 m³

Quantities blinding concrete (rounded):

Concrete volume blinding concrete = 2,250 m³

Total surface sealing sheet = 13,000 m²

Performance sealing works (includes set-up time) = 0 h/m²

Quantities canal bottom slab (rounded):

Concrete volume bottom slab = 1,500 m³

Reinforcement content bottom slab = 110 kg/m³ concrete

Performance steel-fixing (includes set-up time) = 16 h/t

Performance casting (includes set-up time) = 0 h/m³

Quantities canal walls (rounded):

Surface area canal walls = 9,000 m²

Concrete volume canal walls = 1,750 m³

Reinforcement content canal walls = 120 kg/m³ concrete

Performance shuttering (includes set-up time) = 0 h/m²

Performance stripping (includes set-up time) = 0 h/m²

General boundary conditions:

The awarded scope of works comprises the earthworks, the sealing works and the

reinforced concrete works of the canal.

No influences from the surroundings of the canal have to be taken into account.
The specification of construction joints between the sections are yet to be agreed

with the structural engineer and are not part of this task.

Soil condition: Soil classification 4 according to DIN 18300:2012-09.
The slope can be assumed to be sufficiently stable.
All concrete components are made of concrete grade C30/37.
A truck-mounted concrete pump is planned for the casting process.

Name: ……………………………………………….………. Matr.-No.: ….……………………

Task 1 Page 6 of 13

Boundary conditions task b):

• The earthworks are to be neglected in the course of the takt scheduling and

run independently.

• The 1,000-meter-long canal is to be completed after 260 working days.

• The length of each takt section of the canal is 20 meters.

• A learning curve is not to consider.

• The formwork and concrete works will be carried out by your own working crew

(Crew A). The working crew works from Monday to Friday. The weekly working

time is 40 hours.

• Your own work crew (Crew A) also carries out the construction of the blinding

concrete and placing the sealing sheets.

• The placing of the sealing sheet happens immediately after casting of the blinding

concrete.

• Works on the canal bottom slab may begin no earlier than 2 calendar days after

the concrete is casted. The stripping period for the canal walls is 9 calendar days.

• The reinforcement works of the canal bottom slab and canal walls are carried out

by another work crew (Crew B). This work crew will also carry out the shuttering

of the canal bottom slab. The shuttering works of the canal bottom slab is not to

be considered further. Work crew B is employed on the construction site 4 work-

ing days per week. The weekly working time is 40 hours.

• The reinforcement works for the canal bottom slab can first start half a working

day after the start of the sealing sheet works.

Boundary conditions task c):

General boundary conditions:

• The working time is 40 hours a week per worker.

• The total construction period is 16 months.

• The earthworks are to be included in the estimation.

• The construction manager is assigned 50 % to the project.

• There are two foremen assigned to the site. The foremen do not work productively

on the site.

• The formwork is delivered one month after the start of the construction works and

carted off one month before the end of the construction works. The formwork is

rental material.
